•Turn the sound selector to select a sound.

Sound Description

PIANO1 A top-quality grand piano sound with superb presence PIANO2 A concert grand sound, with rich bass notes E.PIANO1 A light and clear electric piano sound E.PIANO2 A crisp electric piano sound with a nice attack HARPSI. A classical and realistic harpsichord sound P.ORGAN A solemn pipe organ sound E.ORGAN A funky jazz organ sound STRINGS An ensemble sound with violin and other bowed strings

Using the pedals

Damper pedal, Sostenuto pedal and Soft pedal can be applied to the HT-70’s sounds. You can use the pedals of the acoustic piano to make your performance more expressive.

Damper pedal

The notes will be sustained while you hold down the pedal, creating a rich resonance. The depth to which you press the pedal will control the amount of damper that is applied (half-pedal effect).

Sostenuto pedal

Use this pedal to sustain speciﬁc notes only. Stepping on the pedal sustains all the notes that you are currently pressing on the keyboard; additional notes that you play while the pedal is already down are not sustained.

Soft pedal

The sound will be softer and milder while you hold down the pedal. The depth to which you press the pedal will control the amount of soft-pedal that is applied (halfpedal effect).

Adding reverberation to the sound (Reverb)

You can add reverberation (reverb) to the sound to create the spacious ambience typical of a performance in a concert hall.

• Reverb will be alternately turned on or off each time you press the [REVERB] switch.

When you change the setting, the HT-70 will write the new setting to memory. During this time, the multidisplay will indicate that writing is in progress (☞p.5).

Do not turn the HT-70 power off while writing is in progress. Doing so may cause loss or corruption of memorized settings and song data.

Setting the Reverb Depth

1. Hold down [REVERB] for about one second.

The switch’s LED begins ﬂashing.

Press [▲] or [▼] to select the desired depth. The multidisplay shows the current setting.

The display shows “01” (shallow), “02” (standard), or “03” (deep).

3. When you have made the setting, press [REVERB] again to return to the original display.

When you change the setting, the HT-70 will write the new setting to memory. During this time, the multidisplay will indicate that writing is in progress (☞p.5 ). Once writing is completed, the [REVERB] LED will either light up or go dark to indicate whether reverb is currently on or off for the sound selected by the sound selector.

Do not turn the HT-70 power off while writing is in progress. Doing so may cause loss or corruption of memorized settings and song data.

If you switch to a different sound or turn the power off before writing the new depth setting into memory, the reverb depth will return to its original setting.

You can specify the reverb on/off and depth settings independently for each sound. With the factory settings, they are set to the settings typical for each sound.

Since the Piano 1 sound simulate the string resonance of an acoustic piano, a small amount of reverb will remain even if you turn reverb off.

The onboard recorder holds two parts for each song. When you make a quick recording without pressing either the [PART 1] or the [PART 2] switch, the recording automatically records to Part 2. This means that you can later record additional performance data into Part 1 for that song. In general, you may have numerous user songs where only one part is recorded. You are always free to record more data into the empty parts of these songs. You may also have numerous two-part songs recorded. Again, you are free to over-record either part at any time, or to delete either part (☞p.16) and then record it again later. The status of each part is indicated by the indicator lamp in the corresponding PART switch, as follows.

[PART 1] / [PART 2] Switch Status of Part

Dark The part is empty or muted.

Additional Features

As an electronic piano, the HT-70 offers numerous convenient features that you can easily use to adjust the instrument’s sound, characteristics, and operation.

Adjusting the Pitch

The built-in pitch control function allows you to make ﬁne adjustments to the HT-70’s pitch. You can use this feature, for example, to adjust the HT-70 so that it is in tune with other instruments. You can adjust the pitch by up to ±25.0 Hz, in 0.5Hz increments. Adjustment is made with respect to note A4, which has standard pitch of 440.0 Hz and can be adjusted over the range 415.0 Hz to 465.0.Hz.

2. Press [DISPLAY] several times, until “tUn” appears on the multidisplay.

When you release the switch, the multidisplay shows the last three digits of the current pitch setting. (The factory setting is 40.0.)

Choosing a temperament

The HT-70 lets you choose from several temperaments (scale tunings). Many classical compositions were composed in historical eras in which the notes of a keyboard scale were tuned somewhat differently than the “equal temperament” commonly used today. For historically authentic performances of such music, the HT-70 lets you choose the Werckmeister or Kirnberger historical temperaments as well as the equal temperament used on most modern keyboard instruments.

•Werckmeister

III

This is the Werckmeister music theoretician Andreas Werckmeister. This temperament was created in the late Baroque era to allow relatively free modulation between keys.

• Kirnberger

This is the Kirnberger the early 18th century. This temperament is used mainly for tuning harpsichords.

• Equal temperament

This is the temperament used by virtually all modern keyboard instruments. In this temperament, every semitone is an equal distance apart, allowing you to play consistently in any key.

MIDI

What is MIDI?

MIDI (Musical Instrument Digital Interface) is a world-wide standard for exchanging performance-related data between electronic musical instruments and computers. You can use the HT-70 to play other MIDI-equipped instruments. When you do so, your sound selections and damper pedal operations etc. will also be transmitted as control data. You can also use another MIDI keyboard or sequencer (automatic playback device) to control the HT-70 and play its internal tone generator. By combining multiple MIDI instruments you can enjoy creating more sophisticated ensembles. You can also save the HT-70’s recorder data on an external storage device via MIDI. This section explains the MIDI-related operations and functions of the HT-70. If you would like to learn more about MIDI, please consult one of the many available introductory books on this subject.

Making MIDI connections

Commercially available MIDI cables are used to transfer MIDI data. Connect these cables from the MIDI connectors of the HT-70 to the MIDI connectors of the external MIDI device with which you want to exchange data. There are two types of MIDI connector.

MIDI IN connector

This connector receives MIDI messages. The MIDI IN connector lets you play the HT-70’s sounds from an external MIDI device (e.g., MIDI keyboard or sequencer). Use a MIDI cable to connect the HT-70’s MIDI IN connector to your external MIDI device’s MIDI OUT connector.

MIDI OUT connector

This connector transmits MIDI messages. The MIDI OUT connector lets you control an external MIDI device using the MIDI messages transmitted from the HT-70. Use a MIDI cable to connect the HT-70’s MIDI OUT connector to your external MIDI device’s MIDI IN connector.

Using the HT-70 as a multi-timbral sound module

When you turn on the power of the HT-70, its internal sound generator is operating as a 16-part multi-timbral sound module that can be played from an external MIDI device.

1. Use a MIDI cable to connect the HT-70’s MIDI IN to the MIDI OUT of your sequencer or similar device.

2. Receive MIDI messages from the connected sequencer etc.

For details on how to transmit data from the sequencer you’ve connected, refer to the owner’s manual for the equipment you’re using.

If the HT-70 is receiving program change messages together with performance data, it will change the sound (timbre) to accord with incoming program numbers as the performance proceeds. Note that this can occur only if the program change ﬁlter is off for the relevant MIDI channel. Note, however, that the selected MIDI channel (☞p.20) ignores program changes.

Filtering resets to OFF when the HT-70 power is turned on.

1. Hold down [FUNC.] for about one second.

The switch’s LED begins ﬂashing.

2. Press [DISPLAY] several times, until “16t” appears on the multidisplay.

When you release the switch, the multidisplay shows the current setting. (The factory setting is on).

3. Press [▲] or [▼] as necessary to change the setting.

Display on oFF Multi timbra on off

4. Press [FUNC.] to complete the setting.

The setting is stored and the [FUNC.] LED goes dark.

The sound selector cannot be used to change sounds while the HT70 is playing externally supplied MIDI data. But note that it is possible for the selected MIDI channel (☞p.20).

MIDI channels

When you’ve ﬁnished making connections, set the HT-70 to the same MIDI channel as the MIDI device to which you’ve connected it. There are sixteen MIDI channels, numbered 1–16.

The channel setting returns to “C01” when the power is turned on.

Local on/off setting

You should turn the HT-70’s Local setting “off” if you want the keyboard of the acoustic piano to which the HT-70 to play only an external MIDIconnected sound module and not the HT-70’s internal sound generator, or to prevent duplicate notes from sounding when you’ve connected the HT-70 to a sequencer that echoes-back (re-transmits) the incoming data back to the HT-70. Normally you will leave the HT-70’s Local setting “on” so that it will produce sound when you play the keyboard.

Immediately after the power is turned on, the Local setting will automatically be turned on.

1. Hold down [FUNC.] for about one second.

Program changes

These messages can be sent by the HT-70 to select program numbers on an external MIDI device, or received from a connected MIDI device to switch program numbers on the HT-70.

Transmitting program changes

Program numbers on a connected external MIDI device can be switched from the HT-70.

• When you change the setting of the sound selector, the HT-70 will send out the corresponding program change number. The correspondences are shown in the table in the next section.

Receiving program changes

When the HT-70 receives a program change number from an external device, its multi-timbral sound generator will change programs as shown in the table below. Note, however, that the selected MIDI channel (☞p.20) ignores program changes.

The HT-70 will change sounds (timbres) in accordance with received program change numbers indicated in the table below. If the remote MIDI devices send the HT-70 a program change number not included in the list below, the HT-70 will stop generating MIDI sound.

The installer will also install the KORG MIDI Data Filer. The Data Filer is not used by the HT-70.

3. Turn on the HT-70 power, and connect the HT-70 to the computer by USB cable. The computer will then automatically install the Windows standard USB MIDI driver.

You must now proceed to install the KORG USB-MIDI Driver for the USB port that you are using.

USB Mode

The HT-70 supports transfer of data between its internal memory and an external computer. A USB connection is the most effective way of making such transfers. This capability is supported by Windows ME, Windows 2000, and all subsequent Windows versions, and by Mac OS 9.0.4 and above.

Before entering USB mode to transfer data to or from the HT-70, please be sure to close all MIDI applications at the computer side. Leaving a MIDI application running while USB transfer is in progress may result in corruption of data at the HT-70.

The HT-70 automatically restarts when you exit USB mode (by setting the mode “oFF” at the HT-70 side, by disconnecting the USB cable, by cutting the connection from the computer side, etc.). This means that any data and settings that have not yet been saved will be lost. Before entering USB mode, be sure to save all data and settings.

The USB connection cannot be used for MIDI communication while USB mode is being used for data transfer.

1. Connect the HT-70 and the computer with a USB cable.

2. Hold down [FUNC.] for about one second.

The switch’s LED begins ﬂashing.

3. Press [DISPLAY] several times, until “USb” appears on the multidisplay.

When you release the switch, the multidisplay shows the current setting. (USB mode is set to “oFF” when the power ﬁrst comes on.)

While USB mode is on, most other operations are disabled. Only the following operations remain available: turning USB mode off, turning reverb on/off, turning metronome on/off, and use of the keyboard to play notes.

4. Press [▲] or [▼] to change the setting.

6. When you have completed the data transfer, remove or delete the USB drive from the computer desktop. For the details, refer to the computer’s instruction manual.

If you are using Windows XP: When you remove or delete the USB drive, the HT-70 automatically returns to its initial (power-on) screen. (If you are using Windows Vista, after removing the USB drive at the computer side you must then press the switch at the HT-70 to return to the initial screen. If you are using a Mac OS: When you move “KORG SSD” into the Trash (or remove “KORG SSD”), the HT-70 automatically returns to its initial (power-on) screen.

Playing MIDI Files

The HT-70 can recognize and play songs stored in the “UserSong” folder, provided that these songs are stored in standard MIDI format and that the ﬁlename consists of a “U” followed by two numerical digits (“01” to “99”) followed by the “.mid” ﬁle extension.

Examples: “U07.mid”, “U34.mid”

The HT-70 may not be able to correctly play standard MIDI ﬁles that use a time signature that cannot be set by the HT-70 itself.

Display on oFF USB Mode ON (Mass storage) OFF (USB MIDI)

The HT-70 will automatically restart when you turn USB MODE off.

Exiting USB mode while USB data transfer is in progress (by setting the mode off at the HT-70 side, by disconnecting the USB cable, etc.) may cause corruption of data at the HT-70 side and may cause damage at the computer side.

Do not turn the HT-70 power off while USB mode is on. Doing so may cause corruption of data at the HT-70 side and may cause damage at the computer side.

5. Once you have set USB mode on, you can use the HT-70 just as any other external USB drive. You can move ﬁles into it and out of it, and you can use it to back up and restore your data.

HT-70 data is stored within subfolders under the “KORG USER” folder. Files within these folders may be given names of up to 128 characters.
