Chapter 1 Introduction

Chapter 1 Introduction

Thank you very much for your purchase of the MFC42. Here, you see its unique features and functions explained.

Features

Four 2-pole Analog Filters
By the combination of four 2-pole filters, the MFC42 can be configured as 8-pole filter unit maximum. The sharp cut-off curve and powerful resonance setting allow wide range of sound making possible.
Stereo and Mono Input
Equipped with the Stereo Input and Mono Input independently and can be controlled separately. For instance, swing the rhythm section from Stereo Input with LFO while the bass from Mono Input being radically changed by manual filter settings – works as two conventional filter units.
Four Filter types
The four filter settings of High pass, Low pass, Band pass and Notch. The filter type can be switched directly by the combination of toggle switch settings.
Groove Modulator
The Groove Modulator function offers the control of filter cut-off or resonance synced to the rhythm. By the combination of Tap Tempo or MIDI Clock Sync functions with LFO/Envelope, the filter cut-off/resonance can be controlled. It also has the Manual Trigger function to trigger the envelope manually at any point.
MIDI function
Almost all keys and knobs are assigned with the MIDI Control Change number. With the use of external sequencer, e.g. MPC2000/MPC2000XL, the movement of each key and knob can be recorded and played back later. The Send Scene function can send all the key and knob settings at once via MIDI. By recording this data at the beginning of each sequence, the settings can later be recalled when played back.
Analog Phaser/Distortion
The Phase Shifter and Distortion effects are built-in. The addition of these effects to the filter control makes the sound control more flexible.
2-Band EQ on Output
With the High and Low EQ at the output stage, the tone of output sound can be controlled.
Phono Input
With the Phono Input provided at Stereo Input with LINE/PHONO selector, the turntable can be connected directly.
2U Rack mountable
The enclosure is shaped so that it can either be rack mounted or placed on desktop to suit your playing style. With the optional mounting kit, i.e. KIT-MFC, the MFC42 can be mounted on the MPC2000/ MPC2000XL.

[Filter]
As the coffee filter, it separates one to pass through and the other to block. In sound application, the separation is determined by their signal frequencies. This particular criterion frequency is called as “cut-off frequency”. There are several filter types of different characteristics.

Filter operation

Let’s master the operation of MFC42, confirming how the sound changes when the signal goes through the filter, in the actual application. The following is based on the connection of rhythm machine (stereo connection), but the operation of the
MFC42 is the same with other devices.
<Preparation>
(Connection to rhythm machine)
Connect the stereo output of the rhythm machine to the STEREO IN connectors of the MFC42. Connect the OUTPUT L/R to your sound monitor system (or connect your headphones to the headphone jack, instead). While the MAIN VOLUME is turned down, turn on the rhythm machine, the MFC42 and then your monitor
system in that order.
(Level adjust)
Adjust the level of MFC42 while playing the rhythm machine. Turn the INPUT and LEVEL knobs on Stereo channel fully clockwise. Next, turn the MAIN VOLUME (or PHONES LEVEL for headphone) up to the appropriate level.
(Panel settings)
Turn the RESONANCE fully counter­clockwise and the CUTOFF knob to 2 O’clock position, and set the FILTER TYPE switches to LOW PASS (both switches down) position. Now, we’re all set to experiment.
(Auto-tuning)
As the characteristic of analog circuitry, the heat makes the filter cut-off operation unstable. With the built-in Auto-tuning function, it self-adjusts the internal filter circuit optimal.
• Press the MIDI CH. and CC NUMBER keys simultaneously to start it (bars on LED flash while auto­tuning). Perform this auto-tuning when the unit is warmed up.

Changing the sound

1. Passing the filter
First, pass the input signal through the filter on the Stereo channel. Press 2 POLE key on the Stereo channel. This makes the sound of rhythm machine go through the filter. You now hear the change in sound already.
2. CUTOFF change
The CUTOFF knob changes the character of sound fed through the filter. Try rotating the CUTOFF knob, paying attention to the character of sound. Now press 4 POLE and 2 POLE keys alternatively while rotating the CUTOFF knob to hear the difference by the number of poles.
3. FILTER TYPE selection
FILTER TYPE, as the name implies, the type of filters is selected here by the combination of toggle switch position. Depending on the filter type selected by the combination of these switches, the way the sound change differs when the CUTOFF knob is rotated. Try selecting the different filter types while rotating the CUTOFF knob. Also, try them out with different pole selections. (Refer to Keywords in basic operation.)
Chapter 2 Basic Operation
4. RESONANCE change
The resonance effect gives the distinguish character of metallic sound. Try rotating the RESONANCE knob. It should sound metallic as you rotate the knob. As the effect of RESONANCE changes largely on the position of CUTOFF knob, try changing the CUTOFF position when the effect of resonance is not so significant.
5. Using the effects
The MFC42 has the Phase Shifter and Distortion effects unit built-in. The phase shifter gives the sound the swirl or roll effect. The distortion effect distorts the sound. Turn the PHASE SHIFTER on and adjust the SPEED and DEPTH knobs. Hear how the sound changes with the various CUTOFF and FILTER TYPE settings. Turn the DISTORTION on and check its effect, also. The output level of distortion is adjusted by the OUTPUT knob. The amount of distortion is adjusted by the INPUT and/or LEVEL knobs on Mono/Stereo channele. These two effects can be used simultaneously.
6. Adjusting the EQ
The MFC42 is equipped with the 2-band EQ. Adjust the tone of sound to your taste with the HIGH/ LOW knobs.
The operation on Stereo channel has been explained above. The operation on Mono channel is basically the same with the following few exceptions.
• The PAN knob is available for panning adjustment.
• The selection of up to 8 POLE is available.

[LFO]
The LFO stands for the Low Frequency Oscillator. The LFO waveform is used to control the pitch, level and character of sound cyclically. In the MFC42, the LFO is applied to the cut-off/resonance to change the character of sound cyclically. Also, the waveform of LFO changes the way it changes the sound character.

Sustain level is the level while the key is held pressed. The Release time is the time between the key is released and the sound diminished.
As in the above example, the envelope is often used change the sound level in time span. In the MFC42, the ADSR envelope is applied to the cut-off/resonance to change the sound character in time span. Note: When the envelope is triggered by the Groove Modulator, described later, the envelope becomes as the waveform shown at “Adjusting the trigger timing of envelope” on the previous page since the sustain time (the time the key is held) is not programmable. Similarly, in the Manual Trigger operation, the sustain time is the time the TRIGGER key being held.

Groove Modulator

What is the Groove Modulator?
In order to control the cut-off and/or resonance and change the sound character cyclically, it requires the setting of “speed”, “way” and “amount” of change. The section that does all these is called the Groove Modulator and consists of the BEAT module, LFO/ENVELOPE module and DEPTH module.

BEAT module (speed of change)
This is the module that sets the speed of LFO and the trigger timing of envelope. It consists of MIDI CLOCK SYNC, TAP TEMPO and RATE modules. One of them is selected to control the speed and timing.
LFO/ENVELOPE (way of change)
This module sets the way the cut-off/resonance is changed. The sound is changed according to the shape of LFO/Envelope specified (either one of LFO or Envelope is selectable, but not both).
DEPTH (amount of change)
This module sets the magnitude of LFO waveform or the depth of envelope. The magnitude of waveform or the depth corresponds to the amount of change.

Control the cut-off cyclically with Groove Modulator (TAP TEMPO)

Cut-off control with LFO
We’re going to explain how to control the cut-off by the Groove Modulator with the rhythm machine connected (stereo connection). Follow the steps below while playing back the rhythm machine.
Preparation
Turn on the LFO, CUTOFF and 2 POLE (Stereo channel) keys. Set the FILTER TYPE as LOW PASS and set the CUTOFF and RESONANCE knobs to 12 O’clock position. Be sure to set the DESTINATION switch to Stereo channel (down position).
ON ON
Procedure
1. LFO speed setting (speed of change)
Set the LFO speed with TAP TEMPO and BEAT keys. Press the TAP TEMPO key twice in sync to the rhythm (default tempo setting is 120BPM). The fine adjustment of tempo can be made with +/– keys. Select the note pressing the BEAT key. Pressing the BEAT key toggles the note selected. Select the crotchet note for the time being (it can be changed later). The length of this note is the length (1 cycle) of the LFO waveform. (Refer to the Keyword in advanced operation.)
Tempo entry Press the key twice.
The tempo is calculated by the time between the first key press and the next. The tempo entered is shown on the 7-seg LED.
ON
2. LFO waveform selection (way of change)
Selects the LFO waveform here to specify how the cut-off changes. Press WAVE key to select the waveform. The key press toggles the waveform selection. Select the “Triangle” for this example.
3. LFO magnitude setting (amount of change)
Rotate the DEPTH knob to adjust the

Chapter 3 Advanced Operations
0
+
In this set up, try changing the note length with the BEAT key or changing the LFO waveform with WAVE key. The way the sound changes is altered while still synced to the rhythm. Further, the rotation of CUTOFF and RESONANCE knobs and/or the selection of FILTER TYPE and the number of poles change the sound as well. The - 3 - key changes the selected note by the BEAT key to triplets.
Cut-off control with Envelope
Now, we’ll use the Envelope instead of LFO. The overall steps are similar to those of LFO.
Preparation
Turn on the ENVELOPE, instead of LFO. Other settings are the same as those for LFO.
Procedure
1. Envelope trigger timing (speed of change)
Set the Envelope trigger timing with TAP TEMPO and BEAT keys.
The TEMPO and BEAT settings are the same as those for LFO. For the Envelope, it only sets the timing of the envelope, but not the length as in the case of LFO. The A/D/S/R knobs adjust the shape of envelope (Refer to Keywords in advanced operation). Select the crotchet note for the time being (it can be changed later).
2. Envelope setting (way of change)
As for the LFO, the Envelope can specify how the cut-off/resonance changes. However, since the envelope has no preset shape as the LFO waveform, it is required to set how to change manually. The A/D/S/R knobs set the envelope shape. Set the A/D knobs to 11 O’clock and the S/R knobs to 12 O’clock position, for example.
3. Envelope depth (amount of change)
Rotate the DEPTH knob to adjust the amount of change. The sound begins to change as the DEPTH knob is rotated to + (or -) side. For easier understanding of sound change, turn the knob fully clockwise here. Note: When the DEPTH is set at 0, no change is observed as the amount of change is set to zero.
Similar to the LFO, try changing the trigger timing with the BEAT key or changing the envelope with A/D/S/R knobs. The way the sound changes is altered while still synced to the rhythm. Further, the rotation of CUTOFF and RESONANCE knobs and/or the selection of FILTER TYPE and the number of poles change the sound as well. The - 3 - key changes the selected note by the BEAT key to triplets.

Chapter 3 Advanced Operations
Up to this point, we explained how to control the cut-off using the LFO or Envelope. The same procedure can be applied to control the resonance by pressing the RESO key, instead of the CUTOFF key. When you want to control both the cut-off and resonance, turn both the CUTOFF and RESONANCE keys ON. Note: When both cut-off and resonance are controlled, it may sound as if the resonance is not changed since the cut-off effect is more dominant.

Control the cut-off cyclically with Groove Modulator (RATE)

Preparation
The same as those used for the TAP TEMPO settings apply.
Procedure
1. LFO speed setting The RATE knob sets the speed of LFO without the settings of tempo and/or note length. Now, try rotating the RATE knob. The tempo is not displayed on the LED, but the flickering speed of upper and lower halves of LEDs changes by the RATE knob setting.
The rest of the procedure for the LFO waveform selection and its magnitude adjustment is the same for the TAP TEMPO settings (refer to page 12).
The procedure to use the Envelope, instead of LFO, is similar.
Difference
Press the ENVELOPE key, instead of the LFO key.
The RATE knob sets the trigger timing of Envelope, instead of LFO speed.
The A/D/S/R knobs set the shape of Envelope, instead of waveform selection with the WAVE key.
Rotate the CUTOFF and RESONANCE knobs and/or change the selection of FILTER TYPE and the number of poles to confirm the change of sound.
Control the cut-off cyclically with Groove Modulator (MIDI CLOCK SYNC)
With the connection of external MIDI device such as the rhythm machine and sequencer, you can control the cut-off/resonance in sync to the MIDI clock.
Preparation
First, you need to connect the external MIDI device that can send out the MIDI clock to the MFC42 via the appropriate MIDI cable (Refer to the operator’s manual of the external MIDI device how to send the MIDI clock out.). The rest of the settings are the same as those used for the TAP TEMPO settings.
Procedure
1. LFO speed/Envelope trigger timing setting (speed of change)
Set the LFO speed with MIDI CLOCK SYNC and BEAT keys. Turn the MIDI CLOCK SYNC key on. The MFC42 is ready to receive the MIDI clock. When the MIDI clock is received properly from the external MIDI device, the “Syn” is displayed on the 7-seg LED. The “no” and “Syn” is displayed alternatively on the 7-seg LED when the MIDI clock is not received properly. Select the note length with the BEAT key and which sets the LFO speed. Note: When the MIDI clock is not received properly, the last used clock rate memorized is used (while the unit is on). The default value of 120BPM is used every time the unit is turned on.
14
Chapter 3 Advanced Operations
When receiving error occurred;
• Check the cable connection.
• Check the MIDI settings of the connected MIDI device.
The rest of the procedure for the LFO waveform selection and its magnitude adjustment is the same as in Preparation for the TAP TEMPO settings (refer to page 12).
The procedure to use the Envelope, instead of LFO, is similar.
Difference
• Press the ENVELOPE key, instead of the LFO key.
• The BEAT key sets the trigger timing of Envelope, instead of LFO speed.
• The A/D/S/R knobs set the shape of Envelope, instead of waveform selection with the WAVE key.

Shifting LFO waveform with L-R PHASE (Stereo channel only)

Try rotating the L-R PHASE knob while the Groove Modulator is controlling the cut-off/resonance. As you rotate the knob, the pan changes cyclically as the phase difference of LFO waveform between the left and right channels becomes larger. Note: The L-R PHASE knob is effective only while the cut-off/resonance is controlled by the LFO. No effect is observed while the Envelope is used.
When the knob is at 0 position,
k
the left and right waveforms have no phase difference.
q
As you rotate the knob to the right . . . the phase difference becomes larger.

Control on Mono channel with Groove Modulator

Up to this point, we explained how to control on the Stereo channel. To control the sound of Mono channel, set the DESTINATION switch to Mono channel (up position). The rests are the same.
Switching MIDI CLOCK SYNC, TAP TEMPO and RATE mode No special procedure is needed. It is switched immediately as the keys or knobs are operated. For example, when the RATE knob is moved while in T AP TEMPO mode, the TAP TEMPO mode is cancelled and it switches over to the RATE mode. The priority is given to the last operation and the previous selection is cancelled.
15
Chapter 3 Advanced Operations

MANUAL TRIGGER

What is Manual Trigger?
The Manual Trigger is to control the cut-off/resonance by triggering the Envelope manually pressing the TRIGGER key at the desired point. The Manual Trigger triggers the Envelope only when the TRIGGER key is pressed, not like the Envelope being triggered cyclically by the Groove Modulator with the specified timing of BEAT module.
Triggering Envelope with Manual Trigger
First, you need to decide what to control with the Envelope, by pressing the CUTOFF key, RESO key or both.
Press the TRIGGER key. When the key is pressed, the Envelope is triggered on and it’s triggered off as you release the key. The shape of Envelope is as set by the A/D/S/R knobs and its depth by the DEPTH knob.
While the ADSR settings are as shown and applied to Cutoff, pressing the TRIGGER key to trigger Envelope makes the cutoff frequency to change as il­lustrated.
Frequency
Key pressed
Key released
Cutoff frequency
Note: When the TRIGGER key is pressed while the Groove Modulator is controlling the cut-off/resonance, the control is cancelled (LFO/ENVELOPE key off) and the Envelope is triggered. Press the LFO/ENVELOPE key again to resume the control by the Groove Modulator.

Controlling Cut-off on Mono and Stereo channels simultaneously

It is required that the signals are available on both the MONO IN and STEREO IN inputs and their signals are fed through the filter modules (x-POLE keys are lit).
Link function
Pressing the LINK key (key is lit) enables the cut-off control of both Mono and Stereo channels simultaneously with the CUTOFF knob on the Mono channel.
Turn the LINK key on. Now rotate the CUTOFF knob on the Mono channel. The sound of Mono and Stereo channels change simultaneously. The CUTOFF knob on the Stereo channel has no effect while the Link function is on.
16
Chapter 3 Advanced Operations
Invert function
This function is used with Link function. It inverts the movement of cut-off control on the Mono and Stereo channels.
In another word, when the CUTOFF knob on the Mono channel is rotated to one direction, the sound of Stereo channel changes sa if its CUTOFF knob is rotated to the other direction.
Turn the LINK and INVERT keys on. Rotate the CUTOFF knob on the Mono channel. The sound of both the Mono and Stereo channels change simultaneously.
Note: The Link and Invert functions only control the cut-off on the Mono and Stereo channels simultane­ously, but the setting of Filter Type and Pole remains as set on each channel.

Chapter 4 MIDI Function

Chapter 4 MIDI Function

By connecting the external MIDI device (sequencer) via MIDI, the operation of keys/knobs and/or the settings of MFC42 can be controlled/recorded, other than the MIDI Clock Sync function described in Chapter 2. Refer to the Chapter 5 for the use of MPC2000/MPC2000XL.
Most of keys and knobs on the MFC42 have the MIDI Control Change numbers assigned and their operations can be sent out as MIDI information. The operation of keys/knobs and settings are recorded onto the sequencer tracks. The MIDI send and receive channels cannot be set independently, however.

MIDI Receive channel setting

Set the MIDI Channel
1. Press the MIDI CH. Key
2. The LED shows the current MIDI channel setting.
3. Change the MIDI channel with +/– keys. The options are OFF, 01 ~ 16, and L01 ~ L16 (L designates Local Off).
4. Press the MIDI CH. Key again to finish setting.
Local Off
Normally, when the keys and knobs are operated, that information is delivered to the filter and/or effect modules as well as sending out the MIDI Control Change messages via MIDI. While Local Off is selected, the MIDI Control Change messages are sent out via MIDI, but not to the filter/ effect modules, when the keys/knobs are operated.
Confirmation of MIDI Control Change number
The MIDI Control Change number assigned to the keys and knobs can be confirmed.
1. Press the CC NUMBER key (LED shows “CCn”).
2. The assigned number will be displayed when you rotate the knob (quickly) or press the key you want to confirm.
3. Press the CC NUMBER key again to resume normal operation.

Recording the knob operation to sequencer

Recording
First, connect the MIDI OUT of the MFC42 to the MIDI IN of the external sequencer and connect the MIDI IN of the MFC42 to the MIDI OUT of the sequencer via MIDI cables. Set the MIDI channel of the recording track and that of the MFC42 to the same channel. Next, start recording the sequencer. The operation of keys and knobs will be recorded as the sequence of MIDI Control Change messages onto the recording track. Playback the recorded sequence. The MFC42 replays the operation of keys and knobs as it receives the MIDI Control Change messages (knobs won’t move, however). Refer to the Operator’s Manual of the sequencer for its operation.

Sending the settings via MIDI

The settings (of all keys and knobs) of the MFC42 can be sent out in one go via MIDI. This is called the Send Scene function. By connecting the MIDI sequencer, the settings can be recorded and recalled.
Recording
Set the MIDI channel of the recording track on the external sequencer and that of the MFC42 to the same channel. Next, start recording the sequencer. Then, press the + and - keys at the same time. The settings of MFC42 will be sent out via MIDI and recorded by the sequencer (approximately 2 seconds). The LED displays “Sen” while the data is being sent. Playback the recorded sequence. The settings of MFC42 will be recalled as it receives the MIDI Control Change messages.
Using these MIDI functions above, replay of the song can be made by recording the MFC42 settings to the beginning of the sequence and further recording the operation of keys and knobs on to the sequence track. Also refer to Connection of MPC2000/MPC2000XL in Chapter 5. Note: It is recommended to use the auto-tuning function, before each recording and playback, for more accurate reproducibility (see Chapter 2 Auto-tuning).

Chapter 5 Connections to Others

Connecting to Keyboard as external Filter Module

The MFC42 can be used as the external filter module. As the MIDI note on message can trigger the Envelope by the MIDI Trigger function (Envelope is triggered by every note), the MFC42 can be used as the VCF module of the synthesizer. The A/D/S/R knobs adjust the shape of Envelope. If the keyboard is the all-in-one synthesizer, the settings and the operation of keys and knobs can be recorded onto the internal sequencer for the replay.
Note: The MIDI channel of MFC42 and that of keyboard must be set the same.

Connecting the Turntable

The MFC42 is equipped with the Phono amplifier in STEREO IN input. The turntable can be connected directly with the LINE/PHONO slide switch selector set to PHONO position. Note: The signal from the turntable is very small and the built-in amplifier amplifies it. Thus, it is strongly recommended to connect the signal ground to avoid noise.

Connecting MPC2000/MPC2000XL

When the MPC2000/XL is connected as in the drawing, its output sound can be changed in real time, as well as syncing via MIDI, recording the keys/knobs operation of MFC42 and backing up its settings. The following explanation is based on this drawing. Refer to the MPC2000/XL Operator’s Manual for their operation.
Changing the sound of MPC2000/XL
Prepare the sequence data of Bass part (Trk1, Ch1) and Drum part (Trk10, Ch10) for the MPC2000/XL first.
Connections
Connect the individual OUT1 of the MPC2000/XL for the Bass part to the MONO IN of the MFC42. The Drum part from the STEREO OUTPUT of the MPC2000/XL is connected to the STEREO IN of the MFC42. The MIDI cables are connected from the MIDI OUT of MPC2000/ XL to the MIDI IN of MFC42 and vice versa.
Playback
Play the sequence data back on the MPC2000/XL. When the keys and knobs are operated on the MFC42, the playback sound of Bass and Drum changes in real time. For example, you may play the Bass part on Mono channel with abrupt filter changes manually while the Drum part on the Stereo channel is swung in rhythm by the slow LFO of Groove Modulator.

Recording the settings and operation of keys and knobs on the MPC2000/XL
The data is recorded onto the sequence track of the MPC2000/XL. Note: Select the empty track for this purpose. If the data is recorded on the track with other data, the sequence data of the MFC42 will be mixed and become difficult to edit later on.
Recording the keys and knobs
As an example, we’ll change the Bass part sound on the Mono channel with the CUTOFF knob and record its knob movement.
First, confirm the MIDI Receive channel of the MPC2000/XL is set to ALL in the MIDI Input window. The ALL is the default setting. Set it to ALL, when necessary. The following illustration shows the MIDI Input window of the MPC2000XL.

3. Record the data on track
Select the track16 to record and start playing back the MPC2000/XL. Move the CUTOFF knob (Mono channel) as the playback of Bass and Drum parts begin. The movement of CUTOFF knob will be recorded on the track16.
4. Playback the recorded data
Press the [PLAY] key to playback the recorded data. When the Bass sound changes as it did in recording, the MFC42’s data is properly recorded on the track16 (You may also check the recorded data in Step Edit mode).
In the above example, only the operation of CUTOFF knob has been recorded, but operation of other keys and knobs can also be recorded as well.
Recording the settings
When the settings of MFC42 have been recorded (Send Scene function) at the beginning of sequence, it can be recalled when it’s played back from the beginning of the song, even if the keys and knobs are operated in the middle of the song.
1. Select the track to record data
Since the tracks 1, 10 and 16 are already in use, select the track other than 1, 10 and 16. Let’s use the track15.
2. Set the MIDI channel on MPC2000/XL and MFC42
The recording track has been selected as track15, but the MIDI channel is set as MIDI channel 16. Since the MFC42 can have only one MIDI channel, the previous control data recorded on track16 cannot be played back when the MIDI channel is set as channel 15. For example, if the MIDI channels are assigned as follows, the MIDI channel data on track16 can be received, but not the data on track15 as its MIDI channel is different.
MFC42 .........MIDI channel 16
Track16 ........MIDI channel 16
Track15 ........MIDI channel 15
3. Record the setting on track
The settings data is recorded at the beginning of sequence in Step Edit mode. On Track15, be sure that the now time is at the beginning of sequence. Press the STEP (F1) key to open the Step Edit screen. Pressing the + and - keys of MFC42 simultaneously records the setting data on the Track15 of the MPC2000/XL. The movement of CUTOFF knob should be recorded on the track 16.
4. Playback the setting data
First, make the MFC42 settings different by moving the keys and knobs from those of recorded data. Now, playback the sequence data from the beginning to confirm the recorded settings on the MFC42 has been recalled (recorded data can be viewed in Step Edit mode).

When recording the settings and movement of keys and knobs on the MFC42 onto the sequencer, it is recommended to record the settings data and operation of keys and knobs onto the separate tracks. Also, record the settings data before the song begins as illustrated. When the sequence is recorded as above, the settings of MFC42 will be recalled before the song begins and the movement of keys and knobs will be reproduced from the start of the song.
Merit in recording on separate tracks
When you want to recall either the settings or the movement of keys and knobs separately, or change the setting or re-record the knob movement, it is easier to make changes on the separate tracks.
Note on recalling the recorded data
The knobs and levers on the MFC42 do not move in sync to the external data. This means that the settings recalled and their actual positions may differ. In the following example,
CUTOFF knob position in recording = 12 O’clock CUTOFF knob position when recalled = 9 O’clock
When the data is recalled, the internal data is at 12 O’clock position while its physical location stays at 9 O’clock. It functions as the knob is at 12 O’clock position.

Connecting MPC3000

For the connection with the MPC3000 and the procedure of recording the keys/knobs operation on the MFC42 and/or its setting data, refer to Connecting MPC2000/MPC2000XL section of this manual.
However, the certain MIDI related items on the MPC3000 have to be set as follows. In the Sequencer Input Filter screen (press MIDI, then 3), select C16 to C26 at Event: field. Set their setting at Pass event?: field to YES and the value at Min change: field to 1. Also, in the MIDI Routing screen (press MIDI, then 2), select the number at Assign Note V ar slider to controller: field to the MIDI Control Change number that is not used for the MFC42, e.g. 27 to 31.
