Digitone MIDI Keyboard quantization

Hello everyone,

I made my move and purchased the Digitone. It is amazing.
I have, anyway, a strange behaviour I am not understanding.

I have a Keystep connected via MIDI to the Digitone, using channel 10 (auto). I’m recording a lead on track 2 which is quantised. I use quantise recording (double play tap), but apparently all notes are still off.
If I do the same procedure using the Digitone Keyboard, everything is perfectly quantised.

Am I doing something wrong?

Thanks a lot for your help!
Tommy
