When I stack a few notes and play them simultaneously, some of the notes won't play.
Reset those knobs to zero and you'll be able to play the sample at different pitches. sounds like a classic case of wrong view in prv. Note end time � the MIDI note end time will be quantized to the nearest grid interval Leave note duration � FL Studio will preserve the length of the note Record to step sequencer � notes are quantized to steps and appear in the Piano roll as zero-length notes Automations � quantize automation clips (not relevant for MIDI) I made sure to go into the view menu and select all keys in the key labels area but nothing changes.
Fl studio piano roll notes not playing MIDI Settings'.
