The MiniBrute (MB) is an affordable analogue mono-synth which offers several Control Voltages (CVs) for use with modular synth systems. As standard you get:
Main audio out
This is amazing for a synth of this price but inside the MB lurk many more useful CVs! Opening up the synth you will see there are many test points, these are all numbered and will make the task of modifying your MB a piece of cake.
I spent the last week poking around with a osciloscope and discovered lots of useful CV signals and waveforms just waiting to zip in to a modular system. Here is what i found:
Power (small board middle, ground main board lower left)
PT720 / PT 605 3.3v
PT175 Ground – there are loads of ground points to choose from, try and stick with one though.
Envelopes (large board upper left)
PT105 Filter Envelope
PT112 Volume Envelope
LFOs (large board lower middle – these all respond to tempo and are MIDI beatclockable!)
PT59 Random Steps
PT58 Smooth Steps
Oscillators (large board mid right – respond to pitch)
PT158 Sub (square or sine as selected on MB panel)
PT22 Triangle (+metaliser if activated)
PT19 Triangle (clean)
PT20 Saw (the modulating wave for this is PT65)
PT151 some kind of folded triangle ( |\/|/\| )
Clocks (large board bottom left)
PT136 Clock out
PT145 Clock in (see special tap emulation circuit)
Modulation (small board bottom right)
PT656 After Touch
PT655 Mod Wheel
PT654 Pitch Bend
there is a thread about the mods on Muffwiggler
And I’ve uploaded fairly comprehensive mod instructions here MegaBrute Leafcutter Mods 03.pdf
Playing with a chaotic patch built around the doepfer ‘chaos patch’ found here http://www.doepfer.de/a100_man/a100_patch.htm
The idea was to get to know some of my modules better and to try and emulate a couple of real-world sounds. I limited myself to 15 mins per patch so they are not perfect but I had a lot of fun and found out a lot about my system – like how much I love the A-199 spring.
In no particular order….
Signal source is a Modcan FMVDO supported by a 110 sawtooth and frequency divided square wave (thanks a-163). Also present the ring mod output of the MFB 0sc-02. FMVDO goes through make noise MMG and the other stuff through a 101-2 LPG. Notes thanks to Turing Machine quantised via A-156. A-199 reverb and a little Dub Jr delay on the FMVDO and the other waves dry
Signal source is an A-106-6 filter on the verge of oscillation, pinged by random gates from 1-149-1 expander. Random pitches from 1-149-1 distribution output. Some drops have a pitch bend env generated by MFB dual ADSR. A-199 reverb and a little Dub Jr delay
Rock Guitar Freakout, (Thurston Moore Simulator)
Basic patch is Piston Honda into A-199 Spring reverb, with PH wavetable modulation. Pitches come from A-149-1. There is a little Dub Jr delay which is randomly faded in but I like the reverb sound better.
This is a work in progress but I thought it might be interesting to some of you. The Max/MSP patch below tracks the price of gold between 1957-2013 and uses the data to control parameters of an algorithmic composition.
It’s a mess but it works!
Here is the price of gold between 1957-2013 expressed as an audio wave
You can clearly see it’s general upward trajectory, it’s a bit like a upwards ramp but with lots of extra harmonic content. This waveform is used for much of the percussion in the piece which you can hear below….

Staubgold and Choo Choo Train Records present an exclusive one-off kind-of-reunion of late 70s/early 80s UK DIY super group The 49 Americans.
The main instigator behind The 49 Americans was Andrew “Giblet” Brenner who assembled a loose, disparate group of musical/non-musical practitioners as an experiment in equality and democracy. At Cafe Oto, Giblet and original members Steve Beresford, David Toop, Max Eastley, Nag and Bendle will perform the songs of The 49 Americans for the first (and only) time after more than 30 years. Moreover, in keeping with the ethos of the 49 Americans, some very special guests, like Leafcutter John and Alice Grant, as well as friends, friends of friends, and even children of the original members, will play, interpret or deconstruct their music, or even make some music of their own.
“Think of The 49 Americans as a band, in the conventional sense, and you’re lost.” – David Toop
With this exclusive evening at Cafe Oto, The 49 Americans celebrate the re-release of their complete back catalogue on the French-German Staubgold label. The Staubgold label celebrates its 15th anniversary in 2013. Label owner Markus Detmer aka DJ Monsieur Croque will guide through the evening on turntables.

@dangusset I have no idea.
Total blast from the past, a 2005 remix I'd completely forgotten about just turned up on youtube. http://t.co/ZgzRZ5LWIn
