Re: Lag/Tracking Generator tips?

2009-01-24 by mattvrazo

Thanks-both those examples are helpful.  I have read the manual, but
alas, they only give one or two examples and despite reading again, I
didn't really get the big picture regarding inputs vs. sources.

For the first example-LFO speed doubling via the TG:  Am i using the
LFO1 as INPUT, and the speed of LFO1 as the source?
