Controlling the ih automatically with the i30: 
I hook up both the send AND return midi 
cables, so that information from the ih can 
be transmitted back to the i30. In global mode, 
you set the midi channel and make sure that 
"system exclusive messages" are enabled. 
On the ih, in learning mode, you specify the 
midi channel to match the i30's (the voicing 
buttons are from the bottom=1 to the top =5 
and the ones across the top are for 10+the 1 
to 5 below or 5 + 10 + the 1 to 5 below to get 
all the way up to channel 16. (my i30 works 
the ih just fine in plain old global channel 1). 
Then, I go to a backing sequence, and record 
an extra track, usually track 8, the last one,
the most likely to be free. As I start the recording 
of the bsq extra track, I simply push whatever 
chordal mode voicing buttons I am wanting on 
and off during the sequence. This is especially 
handy for that tight timing, sometimes I have a 
special voicing pattern for just one word. You 
can enter the CC#'s manually as well, but being
lazy and prefering the tight timing, I just use 
button pushes on the ih, and the i30 "learns" 
them. It's amazing to play back the sequence 
and see the ih going through voicing changes 
all by itself! I start every sequence with the ih 
voicings muted, and end each that way, so it 
never matters what song I am working on, or 
if I change the order of the songs, each song 
starts with the same default position. This is 
important because the ih will remain in the 
position of that last song, and it could be wrong. 
The default solves this problem.
