i have a 300MHZ ibook with 128mb's of ram and a 5400rpm 20Gb HD, and i am trying to use it as a DJ mixer / jukebox. The problem i'm running into is that no matter what i do or what song i play, is that when i am crossfading over from one song to the other and both songs are playing, the music starts to get very choppy and it doesnt stop until the crossfade is complete. i'm thinking it has to be a problem with the onboard sound card in the ibook. anyone have any ideas of what else it could be? i will be trying the software out on a friends 400MHZ Imac this weekend to see how that reacts to the crossfade. The software i've tried so far has been "Mplay" and "disco" for OSX i havent tried the OS9 version of "Mplay" or "disco" yet, maybe i'll try that too.
