[PD] midi strange problem

[cyrille henry]

hello,

i've got few problem with the M4U usb-midi adapter (somtime the internal fifo does not empty corectly). but that's a pb with the hardware.
so i'm looking for a usb-midi interface that is plug and play under linux (ubuntu) and that really work.
any idea?

thanks
Cyrille
