As shown in the video, if I change the pattern length of pattern 0 (empty) from 4 to 2 and saves it, next time the project is loaded it reverts to 4.
I use pattern 0 as an empty pattern I put at the beginning of a song when I record to my DAW via MIDI.
By the way, I’ve just had a freeze I have no clue how it happened but after recording my tracks in Reaper and doing a few manipulations, when I come back to my s2400 it was frozen meaning reboot didn’t work. Only power off.
Before it happened I was recording the separate outs, in the effects analog filter screen accessed from song mode. It seems that the crash happened after the recording was stopped in the DAW.
