I used Fluid on the first bus of the DSP (the Harp preset).
Only other track that was in use was track 2 that had a simple chopped drum break on it. Used the Floaty LV2 delay effect on it. I’ve used this effect in other projects with no issues.
4 bar sequence using note repeat plus Round Robin to record faux arpeggios, recorded and played back perfectly.
Saved as usual and switched off.
Upon switching the 2400 back on, the project gets stuck during the load process. If I remove my SD card the machine boots up as normal and I can re-insert the SD and load other projects, but this particular one always gets stuck.
Created another test project with Fluid on track one, a few simple notes and Floaty on track 2, saved and loaded fine to start with, but then I added more notes using note repeat with round robin on the midi track. Saved and the project wont load again.
Boiled it all down to the issue occurs when applying round robin to a midi track (in my case bank E, either track one or two)
I think the issue is with round robin applied to MIDI tracks in the latest firmware as no projects load once round robin is activated.
