	Hi, instrument 2101 from the Csound Book, using the tempest opcode, does not work for me. Is someone willing to try it out? Perhaps there is an issue with tempest because the following example does not match my expectation as well? p4 is the startempo. "beats.wav" = 120 bpm so i assume that the corrected tempo will be displayed after half a second or so, but it does not. Instead it follows more or less the value of the starttempo throughout the example, but with a very deviation. ; Select audio/midi flags here according to platform ; Audio out Audio in -odac ;;;RT audio I/O ; For Non-realtime ouput leave only the line below: ; -o tempest.wav -W ;;; for file output any platform ; Initialize the global variables. sr = 44100 kr = 4410 ksmps = 10 nchnls = 1 ; Instrument #1. instr 1 itempo = p4 asig soundin "beats.wav" krms rms asig ; Estimate its tempo. k1 tempest krms, .02, .1, 3, 2, 30, .005, .3, p4, 1 printk2 k1 out asig endin ; Table #1, a declining line. f 1 0 128 16 1 128 1 ; Play Instrument #1 for two seconds. i 1 0 2 120 i 1 3 2 100 i 1 6 2 60 e The output is this: i1 0.00000 i1 127.68835 i1 130.55675 i1 135.93220 i1 136.99758 i1 135.06034 i1 138.31908 i1 138.28060 i1 151.15247 i1 158.53091 i1 154.14752 B 0.000 .. 3.000 T 3.000 TT 3.000 M: 32767.0 soundin: opened '/home/menno/csound/Samples/beats.wav': 44100 Hz, 1 channel(s), 88200 sample frames i1 0.00000 i1 97.20582 i1 95.77929 i1 95.14187 i1 95.69701 i1 95.40662 i1 94.94771 i1 92.88452 i1 95.49217 i1 98.95349 B 3.000 .. 6.000 T 6.000 TT 6.000 M: 32767.0 soundin: opened '/home/menno/csound/Samples/beats.wav': 44100 Hz, 1 channel(s), 88200 sample frames i1 0.00000 i1 63.19203 i1 64.82812 i1 66.46707 i1 66.38185 i1 67.86636 i1 67.61985 i1 67.14476 i1 70.85533 thanks, Menno -- View this message in context: http://csound.1045644.n5.nabble.com/tempest-tp4931696p4931696.html Sent from the Csound - General mailing list archive at Nabble.com.

	Hi Menno, I was testing the instrument you send and changed the RMS opcode for the PITCHAMPDF following the example from tempest in the manual. There is some significant improvements. I suppose that if p4 is too far away from the correct tempo, tempest is not able to detect it. Tricky thing.
