Some old fracrack synth modules. The last is a Blacet Mixer Processor. The others are DIY. These DIY modules are
2 x 8 step sequencers. These are barebones they don’t have any quantization or even LEDs for the steps. These have a clock trigger out, forward backward switch, reset, and a carry out which can be used to chain them together.
A 10 step step sequencer it outputs a trigger at each of 10 steps. This has a clock out, and and end step which can be used to make shorter sequences.
2 x LFOs with triangle, square, saw, noise, and step out. These also have a sample and hold.
This will be the fourth time I try to build one of these. I made a PCB for the original using the layout from GGG. I never finished this. Then I built and finished a second using the layout from UStomp.com. I couldn’t get this to work. I forget what the problems were, it was more than a few years ago. Franciso Pena, of Tonepad.com came up with a new and improved version that used 13600 in place of the 3080s. I built the first version of this. It was the most successful of the bunch. It worked pretty well but had two problems that I couldn’t seem to solve. With mine you could hear a ticking from the sample rate oscillator and the sweep switch refused to work in one direction.
Anyway, I found a sheet of PnP that I had printed sometime ago of Francisco’s second version of the FSH-1. I thought what the heck, might as well give it another try.
With a great idea from Brian Marshall of Subdecay I managed to get my 9V sample and Hold working. This ties Brian’s Sample and Hold to the Colorsound Wah. This works pretty good. The range of the effect could still use some adjustment.
