I meant ‘playing technique’ not ‘instrument sound patch’.
It’s unrelated with what VST is used.
Track 1 is recorded with 128 samples.
Track 2 is recorded with 2048 samples.
You can reproduce it easily.
I used DSK Overture for your convenience.(also installed 32-bit Podium for this)
I’m using Steinberg UR12 now. MIDI Keyboard is Roland A-49.
I was using ASIO4ALL with on-board Realtek chip, but same problem.
I think this problem is not due to drivers.
