How can I convert a signal stream to data? There's an object that may work called sig2MIDI but it is only for OSX and I'm running windows. I need to convert an output from the adc~ to raw data (numbers) so I can then manipulate that data to trigger samples etc.

convert-signal-to-data

Right, so if I want a constant update of the converted signal, I should do this, right?

I want to convert the frequency of the signal to MIDI notes, but something is not right. I'm getting strange numbers when the signal is converted. For example, shouldnt 278 Hz (middle C) convert to 60 (middle C)?

Thanks! I had heard about fiddle~ before but I never knew exactly what it did. It's kind of strange to understand how to get it to work, but I'm getting there. Thanks again!

before you are using snapshot~ 5 you might want to use a rampsmooth~ or slide~ before.

All right, I got fiddle~ working with a cycle~. However, when I change the pitch (in midi notes) to 44, the output of fiddle for pitch gives me 0, instead of 44. If I set cycle~ at 45, I get the correct output of 45. but for some reason 44 brings it down to 0. Here's the test patch.

Any ideas as to why it does that? I tried amplifying the signal of cycle~ before it goes into fiddle~ but that just brings the amplitude up.

frequencies lower than 44 Hz are probably beyond what

its quite difficult to fin the loudest fundamental 

below that point. (as well as above nyquist)

fiddle~ is able to analyze.

Ah, I see. But it's not 44Hz, its midi note 44, which is 110Hz.

Oh well, I'll try to work with that then. Thanks very much for the help!

it's cos the window size is too small. it cant identify pitches which have a longer waveform period than the window for analysis.

That's why Roman always precedes his patches with 110, he never got

Thanks Justin. I imagine I can make the window size larger to get even lower frequencies analyzed. at 2048, it wont go lower than 34/33.

You can find most objects here:
http://www.maxobjects.com

The thing is, that when I go to Maxobjects, it takes me to ircam forum and I can't find the object, only some info

Sorry for bother, I'm kind of a newby to the forum

Thanks for your fast answer Chris.
