All actions was performed on common computer keyboard. In 2.6.1 everything was ok.
At the beggining (new song + first instance of surge)everything was fine, i could play chords etc.
After adding, 3rd instance of surge lost polyphony (while inside surge’s gui everything was fine) and started to behave like cheap monosynth.
when i tried to record chords in track, during playback with scroll-lock, renoise recorded linear note sequences, not chords.
when i pushed L. SHIFT and entered chord everything recorded fine, as it should be.
But, while keyjazzing, vsti still behaved like monosynth.
