Perhaps: MIDI setup Keyboard MIDI OUT ------------> Computer MIDI IN Computer MIDI OUT1 ----------> Keyboard MIDI IN Computer MIDI OUT2 ----------> Synth MIDI IN Synth MIDI THRU ---------------> Effects Box MIDI IN http://www.epinions.com/inst-review-737E-184DBA3-39F0EB54-prod1 Computer MIDI OUT2 is connected to Synth MIDI IN and Effects Box MIDI IN in a chain. The warning from the page is: "2. WIRING UP When wiring up a MIDI device to another, there are different possibilities to consider, some MIDI devices only have only a MIDI IN or a MIDI OUT and some have both IN/OUT and THRU. The MIDI IN is always connected to a MIDI OUT device and vice-versa. The MIDI THRU is used to connect external MIDI devices, " here it comes "but it is best not to use more than three as any more can result in a slight delay which will decrease the quality of the music, as modules will sound slightly out of time." I am largely ignorant here but had a vague memory from the 80s iirc and looked this up. all the best, drew _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
