I’m experiencing strange issues with playback in OS3 (all point releases)

In (for example) a 1 bar sequence, when I load a wav from an external drive to a pad on a drum track and enter one hit of that pad in the step sequencer, it will (naturally) retrigger each time the sequence replays the sequence.

BUT if I record an audio track, then convert the track to a drum track and load the resulting sample to a pad and proceed as above, the sample doesn’t retrigger despite the sequence looping.

Can’t fathom it. The pad is set to NOTE ON but it works absolutely fine with a sample loaded from an external drive. It’s only if I sample internally - I haven’t tested whether it’s just with audio tracks or with the sampler/looper - that it won’t retrigger in the sequence. Something in the metadata interfering? Or a bug…? Or just my old X getting gremlins…

When triggering a sample in Note On mode, if the note length is longer than the loop length, a note-off message may occur right after the loop restarts, causing the playback to cut off. Try adjusting the note length or using One Shot mode with shorter notes.

Note length is just shorter than the bar length, doesn't go over.

Moving the event doesn’t change the outcome….
