BI-Polar Presets Test

"Mr. BugBrands fabulous "presets" design adapted for bi-polar voltages. A the moment its outputting about +/-5V which is a little too much for "note" seq'ing, I might swap the 50K pots for 10K (didn't have any 10Ks when I put it together) or I might just leave it because it does make a mighty fine modulator for things like the Wave Multiplers CV etc. Just needs abit of attenuation before it hits a VCO."

Modular Seq_Test

"Alot of my clock modules are controlled by Binary Numbers, so I've been looking at differant counters to build a flexiable divider module to control them, especially the BugBrand Presets module.

This one is built from a 4526 Proggramable 4 Bit Down counter. It has 4 outputs for 4 differant divisions & what makes it rather usefull for pattern generating is it has 4 switches which change the pulse trains at the outputs in differant ways.

In this video a random voltage is being used to reset the counter & I switch various patterns in & out. On the right a CGS Psycho LFO is being used to control the distorted 8008 sound. The LFO feeds a 2 Bit analogue to digital convertor & one of the bit outs controls a gate controlled switch, so, when the Psycho LFO outputs more than 5V a clock from the Binary Counter is tapped off into the trigger input of the drum module."

Pattern Dual I

"Binary Rate Multiplier. Clock goes in, switches set the number the pulse is multiplied by, funky shit comes out!
Just fiddling around breaking in new modules."
