Hi folks... Tran typing here... first off, this is just a quickie hack 669 player I did for myself a day after getting my freebie ultrasound... It doesn't support any of the special 669 commands, only tempo changes... But almost all 669s will sound good anyway... I am releasing this to the public because of the pathetic lack of software for this soundcard... Hope you enjoy this nice little program. BTW: It doesn't care how much memory you got on your ultrasound, it will fill up the memory as far as it can go, and anything thats above that, you simply won't hear... Oh yeah, one more thing, during playback, press + and - to increase and decrease the volume. Be warned though, set the volume too high and your ears may regret it... L8r...
