Hi there,
while programming a guitar part, I noticed the same MIDI controller CC 112 for Vibrato Speed (which I like to keep set to Fast - Tremolo bar) also switches the instrument between Poly and Mono.
In other words, I'm using both features (since my solo goes between sustained notes with vibrato, and single notes using hammer-ons, that is the articulation available only when set to Mono), but those conflict together and ruin the performance.
At the moment I'm unaware if this applies to the other Session Guitarist libraries as well.
Hope this will get fixed as soon as possible, in the meantime if anyone has a workaround for this, it would be very much appreciated!
