I’ve noticed that a Veils can output a negative voltage if in exponential (or near exponential) mode when the input level attenuator is turned up. I’m curious as to why that is. Looking at the schematic it seems like there’s an
AREF_-2.5 that is input in a couple different places in the circuit, and I’m curious if this voltage is somehow “leaking” into the output signal path when the resistance of the exponential potentiometer is low. Note this is probably way off because I know nothing about circuits, hah.
A neat little trick: That voltage can be used as an offset/bias similar to some other VCAs when you mix in a CV signal into the input of a subsequent channel. You can then take this mixed signal, invert it, and then use it in the cv in of another channel of Veils.
I wonder if the circuit could be altered to provide a positive voltage instead. This would remove the need to invert the signal.
