sc88sysex is a command-line program to send and receive system exclusive data
to/from a Roland SC-88 device using ALSA raw MIDI ports. This program is a
Bash script front-end to the ALSA amidi(1) utility.
Roland uses two types of System Exclusive messages: RQ1 (data request 1) and
DT1 (data set 1). This program can build both types calculating check-sums,
and has some mnemonic symbols for addresses, sizes and commands. It can be
used or extended for other Roland and GS devices with few changes.
