This repo includes the mono FV-1 program banks that I have written for use specifically in guitar pedals.
All of these programs exclusively use the left inputs and outputs and assume that the right channel is unconnected. Additionally, all programs provide digital feedback, but no wet/dry mix control. That is assumed to be provided by the host pedal.
If you are looking for a platform for these programs, the Arachnid from PedalPCB is a good choice, and is fairly easy to build.
Some of these programs are derived from those originally written for the Sputnik Buchla format 289 Dual Defect Processor, and the original stereo programs can be found at github.com/wir35/dual-defect-289.
