Problems with SysEx transfers have been noticed with following MIDI interfaces: **Soundblaster Audigy:** some older driver versions don't work reliable, use the latest one **Tascam US-122:** bytes get lost during SysEx transfer, even with the most recent windows driver version 3.3 **Tascam US-122L:** is OK! **Yamaha UX256:** bytes get lost during SysEx transfer under WinXP and 2000 (earlier versions not tested), even with most recent MIDI drivers (Yamaha //universal// drivers) **ESI MIDIMATE:** works unreliable for SysEx transfers under Windows XP. Plain MIDI sending/receiving seems OK. **ESI Rom I/O II:** this device it's driver free, as the USB audio support in the OS automatically supports it (win & mac) but MIOS Studio don't recognize the MIDI Ports of it.
