AJH cascaded VCA No CV control for VCA 2 ?

Post by rafyc » Tue May 04, 2021 4:31 pm

Hi,

Just discovered that Cv2 only act on VCA-1 like Cv1.
So no CV control for VCA2 ? I can't have a VCO-1 on VCA1 and an other on VCA 2 :(
What is the aim to have two CV in for the same VCA ? :hmm:

It's a copy of the original Minimoog circuit. Audio 1 and Audio 2 both flow into VCA 1 which has two CV inputs CV1 and CV2, so you could modulate using say an envelope and a LFO / velocity etc.

I think the master CV input which controls VCA 2 corresponds to a pedal input on the original Moog and defaults to a positive voltage if there is no input.

It's also nice to patch the same envelope into CV1 and master input to get a 'multiplied' faster envelope.

hi thanks for the answer.
In fact Master CV control VCA2 with VCA1 fed into it.

Ok i see the purpose with master and a LFO.
For exemple using an ofset EG in CV2 for a more complex EG ?
Where could i find good patch idea from moog voyager for instance ?
