PrBoom+ has a "mus_portmidi_reset_delay" config option just for this sort of thing, it turns out.

I noticed the same issue on Windows 10 -> CoolSoft MIDIMapper -> UM-ONE mk2 -> SC-55 mk2 in latest versions of Chocolate and Crispy when a new track starts, looping seems to be fine. PrBoom+ with SDL set as the MIDI player has next to no stuttering, but the music sounds muffled, which is why I suppose PortMidi is recommended for hardware - that has stuttering on track start as well.

Thanks, appreciate it!

I'd download that. I can tell these tracks are also noticeably quieter compared to MusicallyInspired's packs.

@Captain Ventris What about the virtual one that Roland sells currently?

This one? https://drive.google.com/file/d/1aadKmjIoJSbc3M4TFycPwvJzzCqP4WPd
