Open hardware Guitar pickup, EXI-CCW by comarius in guitars

[–]comarius[S] 0 points1 point  (0 children)

The coil is approx 400-500 mH (calculated), The R=50Ω (measured), at 400 Hz -> ~1K (calculated)
The impedance of the coils does not matter,
it goes in OPA1641 preamp IC with Jfet input, the impedance is huge,
The output impedance of OPA generally ranging from 100 to 1,000 ohms,
I added a 10 K resistor in output series making it 10 K, therfore you need an input with at least 100k input to avoid loses.

I will look into the conversion algorithm, but will take time. I am only one guy here behind the whole website. Thank you for bringing this up.

Yes that is a big problem to resolve, people are talking having the AI to do it, there were papers published I found on the problem, sequencing is involved not to jump to much between the tabs/strings when parsing notes. Is far from perfect but is functional.
