Subject: Mod Matrix and pitch bending

From: "Jerry Aiyathurai" <tuskerfort@...>

I have been beating myself up trying to do one of those minimoog
style pitch bends, the ones where one oscillator bends up a fifth and
the other stays the same.

Can anyone help me with this. I don't know how to read the manual.
Specifically the chart in page 10 of the data list book. How do you
make sense of the three sources columns (CC AT, Vel KeyRND, and Key
Trck)? are they representative of the universe of sources in some
way? (In what way?)Secondly, how can I find out which
controller/destination pairs are active at the DIRECT setting? I find
this chart confusing and am wondering if someone has figured it out.

For example, from reading the chart, VCO2 pitch would appear to be
controllable by keytrck and nothing else. However I know that it
responds to the pitch wheel at the DIRECT setting. It would be
helpful to read the possibilities off the chart instead of trial and
error on every parameter pair.

Back to the minimoog fifth bend, I have figured out two ways to
approximate it without VCO2 pitch. They are :
1) use oscillator sync, tunes appropriately, and
2) dedicate the pitch envelope (modulating one of the oscillators) to
this trick, controlling pitch envelope depth with the pitch wheel.

The osc sync thing kinda sounds weak and the I hate to lose the pitch
envelope, so I am wondering if there is a better way to do this than
what I have found.

Thanks in advance for your help.

Cheers,

Jerry
