Firmata library for Processing - anybody knows is there a way to call sysexCallback from Processing sketch?
From Processing Firmata source I can see

Code: [Select]
private void queryCapabilities() {
out.write(START_SYSEX);
out.write(CAPABILITY_QUERY);
out.write(END_SYSEX);
}

so this means we need to send bytes F0 (START_SYSEX)  and F7 (END_SYSEX) to Arduino and some bytes in between (command and payload).

But how to send these bytes to Arduino? I cannot use Processing.serial because the port is already occupied by

arduino = new Arduino(this, Arduino.list()[0], 57600);
