Forgot to mention there's a conflict (possibly a symbol conflict)
between A4 and aubio. I think I will have to link aubio statically to
GuitarSynth.
Will try that when I'm back from vacation. UI is the next thing I want
to do, till then you have to use the lv2.

GuitarSynth is now an lv2 plugin. Yep, it's true, thanks to falktx's

A new feature is the Overlay Input: It multiplies the synth output with
the input signal frame by frame. Basically

I wish I had polyphony!! It's only monophone since i'm not an expert on
the matter.
Right now i'm converting it into a lv2 plugin (actually lv2,vst, au by

I have no idea when and how (well not quite how) i'll achieve polyphony,

Interesting note, you must have ears if you can hear the overtones that
clear without amplification.
It also depends on the guitar body itself? A solid body (loke LP) would
behave different than a strat?

This is because the time resolution is divided by 2 and due to
uncertainity the frequency resolution is doubled. Furthermore the input

Thanks. The pitch detection is done by aubio library, but I rectify the
signal before since that stabilizes the detection.
By 'the 6th string' I assume you mean the lower pitched E string? Thats
due to the longer waveform of lower frequencies which would need more
frames per period to be detected.
Thanx. Fixed that and the warnings

Nice to play around. Fast pitch detection and reliable in most cases. The
performance drops a lot when using the 6th string though.
Nevertheless, good work Gerald!
