I think: I know the answer to this - I might be wrong too.
Question: Why don't Cakewalk have Mono Sends?
UPDATE: I know why this was on my mind. So . . .
"The QUESTION should be: Why doesn't the Input of a Send or Patch Point force the signal to Mono?"
The Inputs of a Send | Patch Point from an Aux or Audio Track dont seem to work. It doesn't force the Input to Mono as with Instrument tracks inputs. Wonder if this is a bug?
