Is there a single module that can sum the velocities of the keys being currently played into a monophonic cable?
Current setup
Something like VCV’s SUM?
Sum mixes all channels of a polyphonic signal patched into the POLY input to produce a monophonic signal at the MONO output.
The CHAN lights indicate the number of channels Sum is mixing.
Summing multiple audio signals usually results in an increase of audio levels, so you can account for this by adjusting the OUT level. Pay attention to the LEVEL VU meter to avoid clipping. For example, a four-voice polyphonic signal can increase the peak amplitude by 4, so it is a good idea to apply roughly 25% attenuation with Sum.
