Hi,
ich habe auch so eine PCI64 und habe mich so langsam damit abgefunden,
dass die Karte halt keine MIDI-Hardware hat. Der ES1370 auf der Karte
supported jedenfalls KEIN wave-table-sound. Wie kommst Du zu der
Annahme, dass die Karte 64Stimmen per hardware abspielen kann ?

Ich habe mal die CPU-Last beim Midi-Abspielen unter Windows mir
angeschaut, und die war ziemlich hoch (laut Systemmonitor bei ca. 10%
auf meinem K6). Bei MIDI-Hardware sollte die CPU-Last nicht messbar
sein. Bei meiner alten SB16 mit Waveblaster war auch bei MIDIs keine
CPU-Belastung messbar. 

Ich habe auch so ziemlich das gesamte Internet auf den Kopf gestellt,
aber konnte nirgends irgendwas zu PCI64 bezueglich MIDI finden.

Wenn Du mehr gefunden hast, sag doch mal kurz Bescheid.

Zu Alsa:
Der Sequencer-Part zu ALSA ist noch nicht implementiert, also wird
unter Linux vorerst eh noch nichts MIDI-maessiges mit der Karte zu
machen sein.

Gruss,
