Is there something wrong with the flute samples in KP2? When I play the Flute Solo V instrument non-legato (sustain pedal up), it plays a full +10dB louder than with legato (sustain pedal down).
I've never had this problem before upgrading to KP2. Legato should only be effecting articulation not volume! Anyway the oboe and other woodwinds don't exhibit this behavior. My MIDI Controller #64 "acting as" switch is currently set to "CC only". I've tried all different settings.
