Hi @sean-3086 , thanks for the detailed report!
True—Gate Length and Micromove shouldn’t be used together. They are “conceptually” different: Gate shortens the note within the step, and by definition (see FX Description), it’s not intended to be used across multiple steps. So using both together leads to conflicts and is not supported. To achieve note of any length you can use Micromove on start and end of the note.
Secondly, OFF is by design used to end notes, and it does apply to MIDI OUT. OFF steps can also include Micromove, so they are not necessarily quantized. I will remove “…breaking quantized note length recording” from the title as this is achieved with Micromove. Please double-check all Config > Recording options, as they may influence this behavior.
Also, for future reports, please avoid combining multiple bugs in one topic—it makes tracking and resolution much harder. See How to report bugs for guidelines.
Thanks for your understanding—let me know if anything is unclear. I’ll go ahead and close this topic for now.
