MFOS Sequencer with Custom dual gate sequencer

video upload by O.Z. Hall

"Music from Outer Space Sequencer with MOTM panel designed by DJ Thomas White. I've created a custom module for adding two additional GATE sequencers for extra percussion. I also have a separate CV output for the inner row of knobs. Together with one of the GATE sequencers, it is possible to have two sequences at the same time (same tempo, same end step, same direction).

One other customization is a module (to the left) which will shift the level of a gate to allow a +5V gate to drive the internal clock of the MFOS sequencer. This module also contains two LFOs and two 4:1 multiples.

Finally, the voice you hear is made up of the first 5 modules on the lower row of this rack case. There is a dual oscillator, a Prophet 5 Rev 2 filter (with NOS SSM2040 chip), a programmable ADSR/LFO/Mixer with 3 extra programmable CV outputs to control Resonance and two other parameters. There is also a dual VCA.

The two percussion modules are an MFOS 8 stage phase shifter and a state variable filter modelled after the eMu Universal Active Filter. The phase shifter makes a percussive sound when the audio input is "pinged" by the gate output. It responds to both the GATE on and the GATE off. Thus, the "double time" rhythm. The second eMu filter is the first percussive sound you hear added to the sequence."

State Variable Spring Reverb Demo

Published on Jun 22, 2017 djthomaswhite

"This is a demo of my SVR-101 State Variable Spring Reverb. It is a combination of the Paia Hot Springs Reverb, Crag Anderton (EPFM) Super Tone Control analog filter and a simple DC Mixer from Catgirl Synth (CGS). It is a mono effects device that can be used as:

- Spring Reverb alone
- State Variable Filter alone
- Or combinations of both with the filter being switchable to the main output or the reverb output only, allowing you to EQ and shape the tone of the reverb that is mixed with the dry signal at the output.

I've had these projects since the late 90's but never really used them. I decided to take my knowledge of building DIY projects from the last 20 years to remix the boards into something I would use today. I hope you enjoy the concept and maybe some of the sounds. I am really pleased with the outcome of this enDIYvor."

Not NAMM 2017: DJTW Pocket Mixer Project Update

Published on Jan 16, 2017 djthomaswhite

"This is a video of my updated DJTW Pocket Mixer. It has 1 audio/sync combo input (Teenage Engineering format), 5 more audio inputs, 5 sync outputs and 1 main (mono) mixed audio output. You can chain 6 Teenage Engineering devices together at once with no need for the internal mixing of the Pocket Operator series. This is totally DIY still but now with powder coated case, water slide decal labeling, new style Alpha pots and a more polished look overall. They really add a lot to the Teenage Engineering line of devices but can also work for Volca's. Using them like this would mean 5 shared sync jacks (like a multiple) and 6 mono audio inputs mixed to one main mono output.

The concept is now proven, and I'm looking for someone to partner with to build these. I am working on an "active" powered version but have yet to complete the mixer circuit thus far. I have many ideas about how to do a version of what you see here in this video but with some small and vital improvements. I simply don't have the time between family, work, school and my music business to properly focus on making these. If you are interested in talking about making these happen for real lets chat. It could easily be a Eurorack interface module too."

"Stunning piece of gear: Screaming, growling, yelling, bumping... and this is only the first few turns of the knobs. Fortunatley this is a dual LPG so the signal can be fed into the 2nd gate if needed. And as you see: after the first there is the urge for more!!!!"

it's modular+akai ax-60+volca beats
also the akai at the end got run through a megaohm audio ma20 korg style filter with modulation as I was getting a bit of a feedback/ground hum and it took out the high frequency noise quite nicely and added in it's own little bit of white noise from the gain stage."

DDVCO as 5/4 Pattern Generator
Published on Jan 17, 2013

"Messing around with the SSL Ian Fritz Double Deka VCO's lower-octaves/sub-audio cycles through some Steiner filter resonance with a dash of 'verb. The 10 adjustable nodes of the waveshape can be used to tease out some pretty cool rhythms, but thus restricted to 5/4. Lucky it's one of my fav time-sigs. The further 2 successive nodes are displaced from the center detent in opposite directions (+ and -) the more pronounced the percussive effect/staggering of the waveform/rhythm. Pardon my crappy camera quality."

Heavy Horses and the Vactrol Monsters

"Recently I finished two builds: an LFO designed by me, and the amazing Buchla 292c "Low-Pass Gate" with PCB by Thomas White (panel by Clarke). Both devices feature vactrol inputs for CV control, which makes for some truly magical sounds; I definitely feel like I'm controlling unknown forces of nature when playing on these things."

Dual Cyndustries Zeroscillator

"WATCH YOUR EARS AND SPEAKERS. There are big volume jumps and some sounds clip the poor little FlipHD microphone. Please be careful, I'm not sure the YT encoding is going to limit that stuff and clean it up. This is my first patch with this setup, just screwing around. Through zero FM and Wave Folding from a Metalbox-built CGS Wave Multiplier, through a Thomas White LPG clone and with help from a Topp 281 Function Generator and Fonik Attenuverter. 2nd ZO is in LFO mode and sending CV to every interesting input on the other modules. Noisy! Spooky! Fun!"

Dual Zeroscillator, take 2

"WATCH YOUR EARS AND SPEAKERS. Unpredictable volume fluctuations and very low frequencies. YouTube's compression algorithm has NO IDEA what to do with this. I mean, it's supposed to be noisy and weird but...not that much. Similar patch as take 1, except with a faster envelope for the typical pinging FM sounds. No "Buchla bongos", though. Still the first bit of noodli9ng with this little lunchbox of doom. Careful viewers will spot the point where I turn a knob with nothing connected to it. Oops. Helps to use your eyes. Thanks to Cynthia, Mike at Metalbox, Thomas White, Toppobrillo, Fonik, Ken Stone, and Todd Fletcher for helping make these modules possible."

via Muff's:
"First patch with the ZOWI and associated new DIY and custom Wiard format modules. Completely random noisy noodling; watch for the spot in the 2nd video where I turn a knob with nothing attached to it d'oh! I had an hour with nobody in the house and figured I'd provide the promised videos; more to come for sure. CAUTION: particularly in the first video, there are some big volume jumps and a resonant screech or two. Watch your ears and speakers! The resonance on the Thomas White RLPG is no joke!

Basic patch is: ZO sin output -> CGS Wave Multiplier "Folds" section -> RLPG. 2nd ZO is in LFO mode, one pair of quadrature outs goes to folds CV and Offset CV, the Folds CV is also multed to control the LPG freq. 2nd pair of quadrature outs go to the Attack and Decay CV of a cycling 281 envelope. One Attenuverting output is used as an offset to the v/Oct in of the LFO speed ZO, providing crude manual control of event timing smile Slight delay and too much nasty reverb from a Boss RE-20 in the FX loop of the MFOS stereo mixer that's just offscreen in the Euro rig."
