Perform this procedure after repairs or the like to restore
the RAM to its factory preset status.
This procedure will delete all data currently written to
RAM and replace them with the factory preset data.
1.Turn ON the power while pressing both the [
▼]
and[ALL/ENTER] keys at the same time.
The following display appears.
2.Press the [ALL/ENTER] key to execute initialization.
If initialization is unnecessary, press a key other than
the [ALL/ENTER] key.
To save the data stored in the RAM of the SPD-20 on an
external device or to load the external data onto the RAM
of the SPD-20, use the exclusive MIDI message.
The following explains how to transmit and receive the
data.
NOTE: In some devices, the MIDI channel number and
the Device ID number can be set independently,
and will not necessarily be the same. When
transferring bulk data with another device, refer to
the operating manual for that device.
<How to transmit (Bulk Dump) >
Here's how to transmit the mamory data of the SPD-
20.
Make connections between [MIDI OUT] of the
transmitter and [MIDI IN] of the receiver.
1.Set the Device ID number (=Basic Channel) on Which
Exclusive data will be sent.
3.Use [▲PATCH/VALUE▼] to select the patch data you
wish to transmit (ALL/1 ~ 99). If ALL is selected, all
Patch data, Patch Chain data, and system parameter
data will be transmitted at once.
4.Set the receiving MIDI device so that it will be able to
receive Exclusive messages.
5.Press [ALL/ENTER] and data transmission will begin.
<The time required of transmitting data>
All patch data ЧЧЧЧЧЧЧЧЧЧЧЧЧЧЧЧЧЧЧЧЧЧabout 65 sec
One patch dataЧЧЧЧЧЧЧЧЧЧЧЧЧЧЧЧЧЧЧabout a sec
If you wish stop the operation during transmission,
press [EDIT].
6.If you wish to transmit other Patch data, repeat steps 3
~ 5.
* Exclusive data transmission can require a significant
amount of time, so allow a reasonable time for these
operations. Data cannot be transmitted while incoming
Bluk data is being processed, nor can data be
received while Bulk data is being transmitted.
If Bulk data (Exclusive data) is received during Patch
Chain play mode, the SPD-20 will return to normal
play mode when reception ends.
The ROM version can be checked on the "Version check"
in "Test Mode".
However,if can also be checked with the following
procedure.
1. Trun ON the power supply while pressing both the
[SELECT] and [EDIT] keys at the same time. The
following will be displayed on the 7-segment LED.
The displayed ROM version number is for the EPROM (IC10 on CPU Board).
Here's how to receive Patch data that was stored in
another SPD-20 or in a sequencer.
Make connections between [MIDI IN] of the transmitter
and [MIDI OUT] of the receiver.
NOTE: When data is received, the previous settings will
be lost.
1. Make sure that the MIDI channel of the transmitting
device matches the Basic channel of the receiving
SPD-20.
(refer to "How to transmit"-1)
If you transfer Exclusive data from another SPD-20,
set the basic channels on both units match.
If you receive the Exclusive data that was stored in a
sequencer, set the basic channel to match the same
number which was set when you saved data in the
sequencer.
The readings of 3.3 volts is a proof of a good battery
condition.
If the readings is below 2.2V, the battery needs an
exchange.
NOTE
:
The battery is also monitored during operation and
causes the error message if it goes below 2.2V.
(Refer to "ERROR MESSAGES" section.)
2.To return to the operation mode, press any key.

Preventing mistriggering of two pads tapped simultaneously
■
パッドを同時に叩いたときに発生する音抜けを緩和する方法
Apr, 1998
When you tap two internal pads simultaeously they may
positively trigger the sound. If this is the case, follow the
steps described below.
This information is not found in the Owner's manual.
1. Holding BANK A/B and LAYER, turn on the power
switch.
The display will read 70 which is the factory
setting.
2. This value is the "crosstalk cancel" level set for
the internal pads.
Change this value to 50 by pressing PATCH/VALUE [+] or [-].
Decreasing this value minimizes the chance of missing
sound but increases the chance of cross talk. *1 The
reverse holds true.
*1 Crosstalk: A tap of a pad will cause a different pad to
trigger its sound source.
A pad on the SPD-20 tends to cause crosstalk when it is
not tapped at the center.
Note: With the crosstalk cancel set at 50, strong tapping
of a pad at outer portion (from 2 cm from
periphery) will cause a crosstalk. Ask the user how
he plays the pads and adjust the cancel level in
the range of 60 to 70.
CAUTION: Pads are disabled during setting sequence of
the crosstalk cancel level.
3. Turn off power.
The setting is memorized and will be made effective as
you turn on the SPD-20 next time.
Remarks:
To set the crosstalk cancel level of the pads connected
to the TRIGGER INPUT of the SPD-20, refer to p.53 of
the Owner's manual.
Mistriggering is more likely to occur as two
pads are tapped at the same time and with
uneven forces (or out of the center of the pad).
To reduce mistriggering: Tap pads at the center
with same force; or not at the same time.
