I don't know if this is related to the thread "sysex and cakewalk", but I am having problems with my X5D and SysEx with Logic Audio 5.5.0 on XP (can also reproduce it in Logic Audio Delta 4.8.1). Basically, whenever I send SysEx (even just changing from Combi mode to Multi mode), it seems to lock up the MIDI in port until I reboot the computer. However if I connect using MIDI cables and the interface on my Audiophile 2496, it seems to be OK. Seems to be OK with other MIDI applications though (like Sonar 2.2 Demo, Cubase SX demo). Has anyone else seen this and come up with a solution? I'd prefer to use the PC/IF cable as this leaves the MIDI port free for my other synth. thanks, Andy ---------------------------------------------------------------- This message was sent through the Korgy Park mailing list.
