Using with the Roland SPD-

20 (SOFT THRU)

This section explains how you can use the Roland SPD-20 (a
MIDI controller) together with the HPD-15 to play internal
sounds and an external sound module.
Performance data of the HPD-15 and performance data of the
SPD-20 will both be sent to the external sound module.

Soft Thru: OFF, ON

The messages (except for System Exclusive) received at the
MIDI IN will also be transmitted from the MIDI OUT/THRU
connector when Soft Thru is set to “ON.”
If this setting is not used, leave it “OFF” as the trigger
response of the pads will be faster.

Using a Sequencer or a

Computer to Record/Play

Back the Performance on the

HPD-15

HPD-15 performance data can be saved on an external
sequencer or computer.
For details on the settings for the recording, refer to “Using
the HPD-15 to Play External Instruments” (p. 76), for details
on the settings for the playing back, refer to “Using the HPD-
15 As a Sound Module” (p. 78).
Use MIDI cables to connect the HPD-15’s MIDI OUT
connector to the MIDI IN connector of the external
sequencer, and connect the HPD-15’s MIDI IN connector to
the MIDI OUT connector of the external sequencer.
