There are plenty of controller sources for the matrix modulation, some rather exotic ones like Data Entry, Random, or the KeyAna Course and Fine, which is great, yet some of those are probably not that often used.
I was wondering if there is a technical reason why something like VCO 1 and 2 frequency are no legitimate modulation sources. On a modular system VCOs would obviously be the most used mod sources besides envelopes and LFOs.
An LFO is not really helpful when you want to use a frequency higher than 100Hz and making the frequency change depending on Key Follow. So it would be good to know is there a technical hurdle which can not be overcome ?
Especially since the structure of the signal flow and the whole layout of potentiometers and of course the filter "sound" are so ideal for making Prophet-5 type sounds, i would say no other VA would be as perfect for recreating classic P5 patches !
For that and especially to recreate the Prophet Polymod, the only things missing are Oscillators as mod sources and Filter FM as destination.
By the way, having Filt Cutoff 1+2 as a combined destination, very much like Osc Pitch 1+2 and Osc Pulse 1+2 on the LFO page would be helpful.
Thanks.
