CMOS DRUMS Pt.1

"Messing around with a few new modules. Most of the sounds are the MFB Drum 02 - super simple, 5 drums made out of CMOS inverters; sounds so good.

Controlling everything is my new Divider / Sequencer (bottom left) which divdes the main clock, also using the 4ms RCD (out of shot) to trigger stuff. I don't have much logic at the moment so I'm using a few differant methods to combine gates / triggers.

1 drum is controlled by two gates being processed by the Phase Comparator inside the Doepfer A-196 PLL. Some gates are combined in the A-172 Min/Max, some more in a 3P polarizing mixer. I also have an A-167 Comparator in the mix, the sum voltage fed into the min/max & the gate out controls the direction of the sequencer; you can see it toggling back & forward between the last 2 & first 2 steps (green LEDs)

One of the things that I love about VC is once you have all these processed highs & lows flying about, you can take a voltage & feed that back into the main clock... I think it was the Min. voltage from the min/max.... the CV output of the 196 PLL is in there as well somewhere, as well as a random voltage from the MFB Dual LFO controlling the Decay time of the "synth" sound that comes in...

The MFB modules have plain silver panels... because of the board mounted sockets on them I have to replace the whole panel when I convert to banana format.

All the drum sounds are processed by the Toppobrillo Triple Wave Folder; for extra wood!"

CMOS DRUMS Pt.2


"More fiddlin'

Half way thru I start messing with the comparator settings which ripples out thru the logic chain & alters the patterns... there's abit of luck involved in getting stuff locked in, doesn't always work & its pretty easy to F*! everything up by messing around too much... not to self; ALWAYS RECORD!!!!!!!!!"
