New issue (reproducable on rPI3, 4 and 5 alike).

Setup is either of these PIs + IQAudio DAC+

I have a I2S lcd connected and the rotary encoder (both works fine, scrolling, etc)

When i play just a single note, i hear small "stutters" and after 0.5 seconds the full sound of the patch plays. On the screen, for even a single note-press i see 4 instances of

00:00:25:nn (variable number) mcu: Unknown write nnnnn (5 digit number)

I have tried to play with chunksize and usb-speed, but it will not affect anything.

I control it via USB-A from my Yamaha MODX (in usb mode).
