Hi Soren,
dived into this last night as I just recieved my 128 Vari.
I have a few questions that if answered publicly, might help other people rather than just over skype.
a) Can the operators modulate each other? or is it only the Att/Dec envelopes that can modulate operators.
b) what do the FM freq & amount refer to? the operator works at a frequency, but there needs to be another frequency to FModulate it. whats the other frequency?
c) similarly, what is the LFO that you can alter?
I am sure I might work all this out, but ifs you stick a few hints on Lines, then someone else might benefit.
Its a great app and uses the flexibility of the grid really well.
Sometimes I wish I was using more skill than luck to get sounds out of it.
