HI again.
You can use the Voltage Processors to control volume.
If you
1. connect an OSCs audio output to a Voltage Processor A input, and set the MIX slider fully towards the B input
2. connect the modwheel to the the MOD IN with full modulation amount for the slider
3. connect the Voltage Processor output to where you wan't the output to go
then you can control the volume of that OSC fully.
I attach a preset to import that show a simple example.
especially if/when I have a noise assigned to one of the VCOs.
Keep in mind that the sliders / inputs for the OSCs is modultion sliders/ inputs.
The noise module is a independent sound source. If you connect it to an OSCs inputs, then it modulate either pitch or PWM of that OSC.
Not sure i understand, what you have done. A screenshot and/ or preset would help - if you need more help to this.
And keep in mind that the Voltage Processor Section can be used as an audio mixer, using the sections sliders to adjust the A and B input levels.
