I've been using Logic Pro X for a while but somewhat new still. I've been using my Casio PX 330 as a midi keyboard for months with no issues.
I just bought a mini midi keyboard (MidiPlus AKM320) to have right at the computer for tweaks and the first thing I notice is that velocity on the keys seems to be linked to pitch change, i.e. if I attack the key even moderately hard the pitch bends up a half step and comes back down. I suspect the difference is just that the old Casio isn't velocity sensitive (beautiful keyboard, love it) or not in the same way perhaps.
I'm triggering a Fretless Bass software instrument, and looking through the instrument details I can't seem to figure it out. The included screenshot is I suspect the right place to look, but for example under Mod Matrix where it says "source = velocity" and "target = sample select", if I change that to "none" there's simply no sound. The one below that, LFO 1, seems even more likely since the target is "pitch", but turning that off or changing the target to "none" doesn't remove the pitch bend.
I don't find anything on the keyboard itself to change, and to be clear I don't want to disable velocity sensitivity, I just don't want velocity to change pitch on this instrument.
Any advice welcome, thanks.
