A simple contact microphone and amp in a modular format. Simple but inspiring! Not sure when it will be released yet but keep an eye on


One self patched Doepfer A-143-4 LFO makes beautiful sounds.

Hack your MiniBrute into a Modular MEGABRUTE!

Tuesday, January 28th, 2014 | Building Things, Electronics, Modular Synth, Music! | No Comments


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:

Pitch out

Gate out

Gate in

Amp in

Filter in

Pitch in

Main audio out

Headphone out

Audio in

Midi in

Midi 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)

PT742 +12v

PT743 -12v

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

PT35 Sine

PT32 Triangle

PT34 Saw

PT33 Square

Oscillators (large board mid right – respond to pitch)

PT13 Square

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)

PT57 Noise

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

Have Fun!

Playing with a chaotic patch built around the doepfer ‘chaos patch’ found here


3 modular synth excercises…

Tuesday, January 21st, 2014 | Building Things, Electronics, Modular Synth | No Comments

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….

Church Bells
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

Water Drops
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.
