Re: Anyone interested in Pitch Detection?
I did couple of mono synths several years ago. Main idea was to calculate input frequency and translate it to VCO "input voltage" , like modular synthesis. So , several "compressors"/normalizers were made and Shmidt triggers too. With good basses it has good result. I've test it ...

Re: Reading programs using the dev board
you can read ROM memory, when, decompile binaries to source

Re: Reverse delay?
I hvae only one idea -reset pointer(s) after firt tap of springs or use led indicator to show begin of tact to muscian

Re: Fv-1 preamp Multi effect
You can make short FIR on FV-1 and make overdrive in manner of screamer , but other modern dsp could make it easier (but have other problems and limitations)

Re: Delay Access and Modulated Delays
Are you trying to make delay and chorus in same , maximum RAM buffer?
I see no MEM directives and separate buffers for delay and chorus

Re: Waveform starting point when changing patches/engaging effect
Hm... It's a good way to get sine LFO off battling LFO''s. only 8 lines and range wider than 20Hz

What is about JAM instruction? restart LFO and restart led in MCU

Re: Delay tails and 4049 clock
1. disconnect only input then pedal off. output is always connected
2. pin 10 = oscillator input , pin 9 = not connected.

Re: Can a triangle LFO be used in chorus?
you need one buffer for servo and two triangle LFOs with shifted 180 degrees phase
so, starting coefficient or RRR1 must be 0, for RRR2 - 0.25

Re: log/exp exact coefficients
i don't fully analize your example, but POT is 9 bits, so last 14 bits are zeroes, and you get any low bits only because of 1st order LPF. Another thing is , potetentiometer will have zipper noise because of scratches. Simple LPF will not resolve scratching 100% correctly. One else: you multiply 15 ...

Re: Reducing the tremolo artefact from pitch shifting
you may simply smooth signal by resonant filter and reverb after octaver and compress signal before octaver.
with custom octaver with 256 words cross-fade window, I think, it can give significant result.

Re: Reducing the tremolo artefact from pitch shifting
audio is logarithmic, so it need to square x-fade coefficients to make volume more natural.
wrap, as far as i understand, gets obertones or harmonics , but you need whole tone.
And only one way - make transpose function yourself, with x-fades, filters, etc
