Extending the soundscape of a hexaphonic guitar pickup

--- Quote ---I've had a far-fetched idea of adding some kind of an audio analyser to the setup, having an led bar display for each channel, to show and hold the peaks of average values of say, 5 sec. audio samples, to get the 'profiles' of certain sample's frequencies.

Can you program a PIC micro? (specifically 16F877)
I have a few 101 segment bar graph VFD devices and drivers (I think I'm out of PCBs but the gerbers are in the zip file) . Happy to donate one to the cause if you can use it :-)

WeldingRod, yes, delightful and universal prototyping material.
Bill, I appreciate the generous offer. Only problem is, that I don't know how to program in assembly langue. Back in the eighties I had the Sinclair Spectrum, which had an option to use assembler(was that same as assembly language?). Although I was fascinated by its sheer speed(sample programs from books and magazines), when compared to ones written in basic, I never understood its construction.
Later on, when internet started to grow, there were more info and samples of it available, but still I ended up scratching my head. So far, basic is the only language, that I can comprehend, and write simple math programs. I remember trying out some basic to assembler(or to machine code) translators at one point, but back then the results weren't too spectacular.
Since then, I haven't looked much into it, so in these days, more robust ways to do the translating could be available. As far as I know, there are also Basic Stamp -systems available, but as they don't seem to be as popular, as PIC-based ones, the prices are prohibitive, especially, if one needs several of them for separate projects.
Apart from the "language barrier", an interesting subject.

Today I managed to almost finish the fuzz and super tone control for the vocoder:

Again, the fuzz pcb layout was mirrored, which I noticed(again), while soldering the corner legs of the ic socket.
Anyways, It was a breeze to make a corrected one, as the board is so small.
The way, that the fuzz works with the vocoder is already tested, when it was on the breadboard. The super tone control will have to wait, until the vocoder itself is fitted into the enclosure.
The plan is to use as few switches as possible, to avoid unnecessary wiring hassle, when compared to the original, Paia version.

You could try Mikrobasic for PIC.
I've used it a bit - seems to work well.

Russell, thanks for the tip. I downloaded the demo, but haven't tried it yet.
Now the vocoder has an enclosure, although carboard is still in use for front panel:

There will be at least 7 pots more and one switch, once the fuzz and super tone control are installed. Then plug for the headphones, so the output doesn't need to be connected to the pc's soundcard, while testing.

The free version is only limited by size of program - and the limit still gives you a lot of scope.
