I'm building a simple drum sequencer for a university project.

I have got it all working except when I play each audio file. The wav is sound output is cut short as it moves through the sequence. Ultimately the slower the tempo...the more of the audio file that plays. I have tried using a buffer but I can't figure out where to place it.

here is some sample code on how it works..

When you post code please use "copy compressed".

you would probably want a separate buffer/groove~ pair for each sound. this way they don't cut out on you. something along the lines of the below code (non-functioning!!!!). Have a try and if you have more questions I will be happy to help out more... just don't have the time right this sec :)
