When I play a virtual synth and a patch that has some modulation, like vibrato, controlled by after touch, my S-61 M3 does not do anything, unless I switch AT to monophonic under the keyboard settings. Is this normal for all keyboards that have polyphonic AT? They won’t work with an instrument that does not have polyphonic AT? Or is this a bug with the S-series MK3 keyboards. I created a discussion last week highlighting this problem with Form, but I’ve since confirmed it is the case with other synths as well (eg Bx Oberhausen).
