It's CDJ-only but yes it's in the same category. Main difference is my timecode isn't based on a commercial system (may come in handy if Mixxx gets too popular and those companies want to bring in lawyers), has better latency and needs only 1 audio channel per CDJ. >I think we have some vinyl control experts on this list to help you to >integrate your approach right into Mixxx. Yes; Owen already gave me a good whipping :) One of the challenges is my algorithm is completely alien and as Owen mentioned, there's a limit to how often Mixxx's position cursor can be changed so a higher-latency/high-res driver may hit a brick wall. I'd be great to know which variables establish this limit (CPU speed, HW card latency, internal features depending on FFT width, etc.). >> Vanilla MIDI doesn't really solve my problem with is resolution. > >I have access to a RMX2 controller which also uses 14 bit resolution >scratching.

Maybe the least-intrusive method would be for Mixxx to define a high-level MIDI message template with more resolution based on MIDI SysEx. A better solution I think is for Mixxx to expose a binary shared-lib/DLL API via a class factory for drivers that need to bypass Javascript at runtime but still expose JS prefs at load-time. I don't know enough about Mixxx's internals to say if either makes sense though... other elders should chime in :) Btw another advantage of OSC is that since it's UDP-based it'd be trivial to implement loopbacks, probably make remote debugging easier and could interface with NI/Ableton software. Most end-users probably don't care about those. I've done a bunch of UDP coding recently for a remote log receiver but it's a far cry from the latency range audio apps need. cheers, -- p ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Get Mixxx, the #1 Free MP3 DJ Mixing software Today http://mixxx.org Mixxx-devel mailing list Mixxx-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mixxx-devel
