Latency? Audio jitter? MIDI > jitter? Etc.? Could be better. The bridge will be the same as what the MB supplies for it's PCI slots. The extra power plug means cleaner power and enough drive for the analog audio circuitry. Latency will be the same. Audio jitter is more effected by whats in the card itself. The second link I gave (http://www.jrigg.co.uk/elec/interface.html) actually goes into some detail about that. MIDI is slow at 3khz for words and half that for a key down event. I wish I could use my boca board for that (from BBS days) with 16 uarts. 16 outputs one for each synth. But I think it is actually an isa board. If I ever use it again it will be with netboot dx66 or something and just enough OS to get it to network. Anyway, jitter is more in the software and drivers and how they handle (or don't) the midi signal. -- Len Ovens www.OvenWerks.net _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
