I've been looking for a high-performance music engine. It must have an asynchronous control (socket, pipe?) mechanism to seperate the application from the audio thread. I'm looking for: start/stop samples on the beat scaled tempo control across all samples volume effects? easily wrappable (I'll write extensions, implement protocol plugins...) with python I'm trying to write something like ableton live without writing an engine all over again. FMODex would be *perfect* if it had a well-defined tempo/beat/sync interface. thanks -- Patrick Kidd Stinson http://www.patrickkidd.com/ http://pkaudio.sourceforge.net/ http://pksampler.sourceforge.net/
