The problem we have with gen~ is that it doesn't have a facility for output parameters in the same way we have
send in Pure data.
This is a limitation with gen~ with no obvious workaround. There may be a way to use the 'history' object to update output values, but it's not working in the current version.
As a work-around, what we're planning to do is support additional outputs from the patch and assign them to the CV outputs. This way, when you create a patch with say 4 outputs in gen~, the first two will assigned to the audio left and right outputs, and the other two to the CV outs.
No I'm afraid not! The two signals are combined in the analogue realm and presented as one value. When you plug a an input into CV A or B, the knob becomes an attenuator for the (analogue) CV signal. This means that the Wizard can be used with Eurorack level CV signals by just turning the level down, with no loss in resolution at the ADC.
