I want to take an Audio In and be able to recognize the pitch. I would use it in the context of the Note Detector or the Compare mods. Basically, I want to be able to recognize a certain pitch coming through the Audio In and then send a logic signal to trigger something. Is there any way to do this? The closest I can get is to compare the volume of an Audio In to something else (and this is nothing like what I want to do).

I think the 'note detector' only detects midi notes, so it won't work. 'Compare' does, though. Search the patch archive for 'pitchfollower'. They work great, just need to be adjusted for whatever instrument you're using.

Clavia stated once the FilterBank could be used in such manner. I don't have time to check now

I'm off to the The Hague QueensNight (KoninginneNach)

Here is a patch which recognizes pitches in 1 octave. It is based upon a pitch detection circuit (Lowpass filter, followed by a pulse and smooth module) which I also used in several other pitch-tracking patches. The output of this circuit is passed to a series of compare modules combined with logic processors, which decide what envelope module is triggered. Ofcourse the outputs of the logic processors can be routed to anywhere you like. And the levels of the compare modules can be altered to take care of other pitches. Be sure that these levels stay in ascending order for proper operation of this patch.

Indeed: "The Filter Bank is a 14-band static filter with attenuation controls for each frequency band. The Filter Bank is very suitable for simulating different kinds of body resonance (formants). It can also be used to filter out a specific frequency range of an external audio signal. For example, you could connect a CD player or similar to the AUDIO IN jacks, and route the signals via the Audio In module to the Filter Bank and filter out kick and snare hits and have them trig different modules in the patch." (from the help file) Has anyone tried this

I don't know who made this, but I've tried it and it works.

Clavia website had a link which describes how the trick was done on Cher's "I believe"

Sorry for getting back to this item so late, but I was out for some days and didn´t have the red box with me. I once too tried to create a patch which would react on incoming pitches (audio) by sending clock pulses, for a performance piece with live-instrument, and found a quite "cheap" solution, to leave me some dsp for several of theese modules: it just needs a digitizer tuned to the frequency and a pos. edge-delay. the attached patch contains this and a test-section with a simple sinus-oscillator. once you get "tuned" (i.e.the test oscillator -knob 1- matches the frequency of the digitizermodule, the sequencer starts playing. to do other things, e.g. trigger an envelope is up to you. for proper working with real instruments you may have to tweek the bit-rate of the digitizer and the delay-rate. (I got to set it up with a tenor-recorder).
