The code below should work, but doesn't even though it produces a signal related to the slope (slope with alternating zeros and interpolations). The errors look like they're related to the use of the K-rate controller even though I'm using K2A. Perhaps I'm misunderstanding what K2A does. The ugen "Slope" does the same thing. How would you do this? Paul Koonce Synth.scope({ var a, b, c ; a = MIDIController.kr(1,1,0,1,'linear'); b = K2A.ar( a ); c = FOS.ar(b, 1.0, -1.0,0.0) ; // OUTPUT SLOPE [b, c * 2000 ]; }, 1.0 ); ------------------------------ Date: Tue, 30 Oct 2001 21:08:11 -0600 From: James McCartney <---@---.---> Subject: Re: slope of controller If you changed this line perhaps what is happening would be more clear: a = MIDIController.kr(1,1,0,1,'linear',0); Now the lagTime is zero. MIDI control updates are intermittent giving a staircase function, not a continuously varying signal. So the slope is usually zero, unless you get a new value for the controller, which makes an impulse in the slope. With a nonzero lagtime the impulses decay, giving a saw effect. on 10/30/01 7:58 PM, Paul C. Koonce at koonce@phoenix.Princeton.EDU wrote: > > I want to get the slope of a MIDI control signal.

My question is: How can I use the freq data (from the example above) instead of Mouse.kr to trigger notes from the mode (when the actual freq happens to match one of the notes of the mode)? I know I could try to use an Identity dictionnary or conditional statements (if) to get the same result but it would not be as flexible as using DegreeToKey since I can easily send new Float arrays to change mode during the performance.

I would choose an Identity dictionnary, but your idea of DegreeToKey could also work. Remember that the mouseX in the example gives the index of your table, so you have to convert the freq. into midi-notes using cpsmidi (round is also done by DegreeToKey) and give a float-array of 127 points (complete midi-scale) as input table. Other table-lengths will give repeats after so many steps (with octave shifts), a length of 12 will give the same layout every octave you play. You could also process the output of cpsmidi before feeding into DegreeToKey, for instance */3 will give a new output every minor third you play. by, Hans >Hi, > >I am using a theremine (through AudioIn) to trigger >a sinewave with the Pitch object (simple). > >////////////////////////////////////////////////////////////////////////// > >( >{ > var in, freq, hasFreq, amp, sig; > > in = Mix.ar(AudioIn.ar([1,2],1)); > amp = Amplitude.kr(in, 0.1) thresh: 0.005; > > #freq, hasFreq = Pitch.kr(in); > > > freq = freq.cpsmidi.round(1).midicps; > > FSinOsc.ar(freq,amp); > >}.play >) >////////////////////////////////////////////////////////////////////////// > >Now, I would like the AudioIn to trigger only certain notes from a mode >(and not all the MIDI notes). > >I thought of using DegreeToKey to convert the signal to modal pitch. > >The Help file for DegreeToKey uses MouseX.kr to truncate the signal >to values from a FloatArray a ndtrigger pitch from the chosen mode. > >My question is: > >How can I use the freq data (from the example above) instead of Mouse.kr >to trigger notes from the mode (when the actual freq happens to match >one of the notes of the mode)? > >I know I could try to use an Identity dictionnary or conditional >statements (if) to get the same result but it would not be as flexible as >using DegreeToKey since I can easily send new Float arrays >to change mode during the performance. > >Any idea? > > Thanks. > > Fabrice Mogini >-------------------- ============================================================ Hans van Eck: schreck@xs4all.nl Schreck-Ensemble: http://www.xs4all.nl/~schreck Buy a Schreck CD at: http://knorretje.hku.nl/~schreck/cgi-bin/nph-BUYCD.cgi Tel.: "+31"-(0)20-6968957 ============================================================ ------------------------------ Date: Fri, 2 Nov 2001 12:55:42 +0100 From: Julian Rohrhuber <---@---.---> Subject: Re: Pitch follower+Degreetokey a KeyToDegree ugen wold be nice..

There is no once and for all solution for this, but for a specific case, like the theremin, it should be feasible. ------------------------------ Date: Sat, 3 Nov 2001 17:52:30 -0500 From: sonsgard <---@---.---> Subject: PlayBuf patch request Dear SC List, I would like to play soundfiles with SC and dynamicly control both length and start point of playback in the buffer.

I have changed the sampling rate to 48k (with a motu interface) in the audio setup, which is confirmed by Synth.samplingRate. When I record, however, the files are still written at 44.1k. As far as I can see from the documentation and the .sc files, I have no option of changing the sampling rate in the arguments for the .record method. The recorded files are then longer (not 5 secs but 5.44, for example), meaning that all of the data is there, and I can change the header to 48k in SoundHack, resulting in the correct length and the correct pitch level. Does anyone know if I have overlooked an argument, with which I can tell SC to include an indication for 48k sampling rate in the header?
