Mod Matrix and pitch bending

2001-06-21 by Jerry Aiyathurai

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
