Re: LFO mod of VCO (was Using Velocity)

2005-02-23 by tontaub

If it's just attenuation without any time dependency you virtually can
do that whereever you want (mostly depending on the rest of the
patch). If you want to control that remotely from a let's say MIDI
keyboard you will need a VCA which is controlled by the MIDI-CV interface.
However - no one stops you to grab the knobs of your modular when
playing ;-)

Did this answer your question?
