This is amazing ! Congrats.
Eager to try the sidechain, this machine/os will really be something special.

Thanks for considering the features, multi line is quite neatly implemented imho. Also worth looking into the slice mode in TG which is pretty nifty.

Resampling and sampling from usb also came to mind 😇
