jimusic,
This might be getting too far from the original post, but I'll try to explain one time here.
First, you need to consult a system exclusive message guide for your synth since each handles sysex differently. Second, you construct the sysx file inside SONAR under the Sysx View. Here is an example of selecting the Multi mode on a Korg Wavestation.
F0 42 30 28 63 00 F7 all sysx files start with
F0 and end with
00 F7 42 = Korg ID
30 = Korg format (3n, where n = channel number in hex [0-F])
28 = Wavestation device ID
63 = message type code, in this case "multi mode select"
Here's one that changes a parameter on the synth - setting the pitch bend range to 12
F0 42 30 28 41 2E 00 31 32 00 F7 Notice it starts out the same until...
41 = message type code, in this case "parameter change"
2E = LSB of param # (pitch bend range)
00 = MSB of param # (pitch bend range)
31 = hex code for ASCII of first character of parameter value (in this case = 1)
32 = hex code for ASCII of next character of parameter value (in this case = 2)
F0 42 30 28 41 2E 00 32 00 F7 would set the pitch bend range to 2.
Once you see what these can do it's easy to come up with a lot of useful files. I have some projects that send 6-8 files setting modes, pitch bend range, even selecting patches.
