1. Setting asio buffer size large(larger than 1024 samples).
2. Record MIDI.
3. Playing staccato chords.
4. Some notes are recorded extremely short duration (shorter than 1/32 note at 120 bpm, 4/4).

I know nobody record midi with this large buffer size.
But after this test, I’m beginning to suspect everything.
How can I believe recorded note length is ‘correct’ even if I record with moderate latency setting.

I changed midi keyboard, audio interface. Same result.

Hi,
I did several tests. This is the result.

The settings are visible in the picture.
You did not specify which driver and which VST plugin you are using. Perhaps the problem is due to one of these.

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.

Ah, sorry, I’m a nag!
Got it … I hope.

You’re right. I never noticed it because, as you have seen, I’m not a musician, so I don’t play/record almost never.

The problem is related to latency?
more samples = more latency -> incorrect notes (?) 😕
What about…
