VCA Envelope on forever mod not functioning

Post by Dixie237 »

Hi all,
I'm working with a friend to mod up my unit. So far we have added 2 extra oscillators with independent volume control and power on / off control and delay. All good, works fine, sounds like an animal.
Next mod on the list was the VCA Envelope on forever mod. So we did this, installed and fully tested, switch, 12v feed etc (my mate is a qualified electrical technician by trade so pro soldering and testing) ...however switch activation produces no difference. I was (correct me if I am wrong) expecting upon switch activation to have the current note in the sequence hold. Again nothing.
Am I understanding this mods function correctly?
I have run the unit with only the first osc, volume off and triggered. No difference
Volume up, envelope fully down and triggered. No difference.
Combinations of the above to no effect.

I have just read online that perhaps in need the Gate on forever mod in conjunction with this to produce the "note on forever" I am after.

Any help much appreciated. Thanks in advance all.

Cheers
D
