Thanks a lot Mark, I'm going over them now. I'm sure this is some mishit but line
26535,TotalTrack Control:0,Control change,1,12,62 in "numark_tc_slow_clockwise_revolution.txt" seems out of place. Looks like a pure speed data so far. I also looks like the sensor resolution/sampling frequency is so low that it misses a lot of ramping data. This is most noticeable during the spin data set. Unless it is a delta speed (acceleration) whereby the acceleration is high to start and slowly drops to zero. But the slow_revolution data files seem to refute that possibility since the data seems constant and the delta speed would more likely be varying from positive to negative if you're trying to maintain a constant speed I think it's worth exploring that if the microcontroller uses interrupts, or polls at a higher rate, we could do better than this using standard midi, provided the sensor has the resolution. Also on the fast revolutions, you're getting ~20 data points in best case 0.25 seconds, that's 80 Hz. That's pretty slow. It's probably worse considering the error when stopping the timer. -Nick ----- Original Message ---- From: Mark Glines <[email protected]> To: Nick Conway <[email protected]> Sent: Wednesday, March 11, 2009 8:36:21 PM Subject: Re: [Mixxx-devel] Midi Encoder data details Mark Glines wrote: > I'm hoping this will indicate how sensitive it is to angle and time. HTH, Just to clarify, the dumps are in reverse chronological order, so newest first. The record fields are mostly self explanatory, the first record appears to be a timestamp, and the turntable I was fiddling with is widget #24 (and the other turntable is #25).
