Re: Dotcom compatibility with a MOTM & Modcan?

Re: Dotcom compatibility with a MOTM & Modcan?

2008-10-29 by warpt666

I think I'm getting it now. 

If I were to use a .com oscillator to modulate the a Modcon osc, I'd need to turn the signal 
down or get an extreme or high amount of modulation. 

If I were to use a Modcan osc to modulate a .com osc the amount would be weaker or less 
extreme. 

If I were to the output of a Modcan filter into a .com VCA would the output signal also be 
half the volume? Seems logical, but I thought I should ask. 

I guess my question would be, is there a way to boost the Modcan signal? 

Chaotic modulation is what I'm hoping for...  :D

Again, thanks for the help. I do appreciate it.

Yes, the biggest level concern is when using Modcan oscillators to modulate Dotcom and 
MOTM but Modcan VCAs can double the input signal (20v max) and there is always the 
Dotcom signal processor. I've never had a problem with the inputs of Modcan modules, 
and , in fact, some are designed to handle 10v signals (flanger, mixers) and the new digital 
Quad LFO can be set to +-5v. All three systems use 5v envelopes.

Good info, David, thanks.


To warpt666, you've got it right, here:

The thing is that many people aren't much into extreme modulation, so 
these level mismatch issues are somewhat academic. To "turn the 
signal down or get an extreme or high amount of modulation" is what 
we do most of the time, anyway.

On the other hand, some users -- including you, apparently :-) -- are 
very much into extreme modulation, and that's where you could find 
yourself needing to amplify the Modcan signals. (Which can be done 
with a dotcom Instrument Interface or the top section of a dotcom 
Signal Processor, for example.) And, after all, one of the best 
things about modular synths is the ability to do unusual and extreme 
things when you want to do so.
