tried out the audio2pitch with my guitar.
it works for lower notes but is really erratic at higher pitches. Also latency is quite big.
I also had to tune the oscialtor up 5 semitones to have the right pitch.
So right now it is for me not really usable. Are you planning on tweaking this a bit more?
This is the setup:
I've gotta say, I'm not surprised. Pitch-detection for guitars is really hard to do. Even the expensive guitar synths by big companies like Roland aren't that reliable, according to the reviews I've read.

That's true but this roland things are also polyphonic, so that's also more a matter of picking up each string indivdually. And of course quick playing techniques like hammer ons, trills etc are not so easy to translate.
Monophonic pitch detecetion on the other hand is not too tricky I think. Each cheap digital multifx unit has like a monophonic guitar synth.
On the axoloti there is this yin object by @joren, wich did a pretty decent job on the guitar but wasn't yet finished and crashed my axoloti patches.
So i think monophonic should be absolutely doable 
I was really intrigued by this, but @joren never replied to my PMs about it. I guess he abandoned it. Shame..

you might add some extra lowpass filtering to remove more high frequencies and maybe an extra highpass filter at 20hz to remove sub-frequencies.
I used zero crossing technique for getting the pitch and to be able to get the right pitch, I needed a longer buffer, otherwise there was this contstant offset. Though there are some ways to improve this.
at the moment I'm coding a random oscillator which, hopefully, just stays around or under 4% cpu..
Ok thx the filtering helped a lot!
I think I will build a pickup just for the low E string on my guitar and use this to create a clean sine sub for my guitar synth/sampler:
NEW MODULE
OSC
"randOsc"
oscillator with randomisable waveshape.
Uses up to 64 steps and features both a seeded random as well as a triggered-randomise option for both waveshape-amplitude and waveshape-amplitude-update (where the shape changes to other values).
The whole array goes through a filter (yes, this becomes a smoothly faded array->morphed waveshape).
A mix-knob (SeRa) allows to set the mix between seeded and randomised waveform.
Multiple knobs and inputs are given to modulate the oscillator.
Hi
randOsc is great module thanks 
little bug - smooth not working (see code and range value smooth is 0 to 0)
Dear SSS,
While you're being so outrageously prolific, have you thought about enhancing some of the GPIO interfacing objects? It would be great to have better options or wrappers for exporting and importing Axo data out over i2c, UART etc.
The inlet/outlet tabs in the Editor are still quite glitchy in my experience. It's not hard to do things you didn't intend when working in these areas.

yes, I think it happened when I editted the desciption boxes just before I saved it to the community.
I haven't even touched these things yet haha
after 4 months, my axoloti is still a bare-bone circuitboard. I'm still thinking about the best layout and options for controls (eg. thinking about adding a multiplexer so I can choose between using a slider, knob, button or encoder for each control) that is directed towards the use of my modules. So first I'm gonna create all the modules I want and after that I'll focus on the internal/external control of those.
new module coming up
4 voice poly oscillator

NEW MODULE
DISP
"LFO_xy_scopeLowRes"
trying out whether I could a very low resolution xy scope using the "button-row displays"-thingies.
Takes in positive fractional signals and shows the xy position in a 16 by 16 steps matrix
NEW MODULE:
OSC
"syncModOsc"
multi-modded oscillator featuring a big bunch of options for morphing your sound
audio modulations:
-linear and exponential FM
-PM
-AM
-softFM (phase modulation by pseudo-derivative of sync-input)
audio syncing:
-hardsync
-softsync
-sample&hold wave and add to original at sync
-reverse play direction
-shift phase by pseudo-derivative of sync input at sync moment
as far as it was usable, all parameters have external inputs for audio, mod-width and off/on sync-options.
while fully modded with several K-rate modules (including tempoSyncedLFO) and a sine-oscillator in the same patch, the cpu-use is 10%
NEW MODULES:
PATT
'rndEuclidPatt"
pseudo-random pattern generator
-randomise pattern externally or manually
-"repeat" sets euclidian stepsize where "gates" are generated
-"width" sets the width of these gates, being added to the sequence.
-4 euclidian patterns are combined with the random pattern to generate a looping CV-pattern
"sRndEuclidPatt"
a simplified version of the above, featuring only 1 euclidian pattern and a random pattern.
NEW MODULE
OSC
"polyWaveform"
4-voice "chord" oscillator with multiple waveforms
connect a positive saw-LFO (non-bandlimited) to the morph input for normal operation
connect an attenuatable LFO to the mofs input to "swing" the morphing
connect note patterns to the note(1-4) inputs, these will be scaled to the selected key internally
"PW" controls an exponential shaping of the phase, generating PW-modulation for all waveform-options
"waveform" controls the selected "base-start" waveform
"wChg" sets different waveforms for each voice, one knob for all possible combinations **use shift+ctrl to get to smaller bits
"detune" offsets the pitch between the 4 voices.
"key" sets the key of the scale. (negative values for minor scales)
"polyScanner"
variation on the above with only a sine-wave with PW-control
adds a XY-scanner to scan through the 4 voices using external LFO's
"polyFMOsc"
variation on the above with only a sine-wave, but with added internal Fm.
This one can make some seriously weird morphing sounds!
NEW MODULE
ENV
"quadEnv"
Quad Attack/decay envelope, linear attack, exponential decay.
"Amin", "Amax", "Dmin" and "Dmax" define the range of the attack and decay values for all 4 envelope generators.
Values are spreaded following a sine-curve of 45 degrees offset for each envelope.
"Amorph" and "Dmorph" set the position within the sine-curve, allowing to morph all attack and decay values simultanuously between minimum and maximum range.
pairs very well with the polyFMOsc (see former post)
