The Matrixbrute is a 3-VCO, monophonic synthesizer with arpeggiator, 64-step sequencer, dual filter, 2 LFOs, 3 ENVs, pressure & velocity-sensitive keyboard, CV outs and ins, and extensive matrix modulation, and more. Although it is monophonic, each oscillator can have a different sound, and they can be variously assigned, so that one could carry the sequence, and the others serving as the lead. Through matrix modulation, the oscillators can be transformed into other sounds using the foot pedal, modwheel, or aftertouch. The sequencer can reset with every keypress so that sequences longer than 64 steps can be played. (Examples can be found in my YouTube videos). This synth has never left my studio. It is programmed with sequences of Tangerine Dream, Edgar Froese, Chris Franke, Peter Bauman, Johannas Schmoelling, Pink Floyd, Jean Michel Jarre, Emerald Web, Kitaro, The James Gang, Santana, Traffic, Alan Parson's Project, Iron Butterfly, and others. The sequences can be found in 9 separate videos on my YouTube channel: <wedream2>. Examples include: Phraedra to Tangram <>, The Sorcerer soundtrack, Tangerine Dream—Logos, Tangerine Dream & Edgar Froese, Tangerine Dream & Chris Franke, Tangerine Dream, Bauman, & Schmoelling, Emerald Web & Synchestra, Kitaro, Pink Floyd and others. See patch program list in above pictures, (banks I, J, M, N, O, & P for names of sequences). I had uploaded some of these sequences to the Matrixbrute face book users group, but was informed that they don't play back with the latest firmware update, so I have not installed the latest version. This can be easily done, but I would suggest using the Matrixbrute as is and doing the update later. This will give you an opportunity to learn those sequences of interest and write the notes down so that they can be programmed back in after the new version is installed. The update expands the matrix modulation slots, which are not really necessary for a novice.

If you have another monophonic synth, such as an ARP 2600 clone, you can use the Matrixbrute as a keyboard controller through midi and can arpeggiate or sequence the external synth. It also responds to pitch bend. You can also use the CV ins and outs to connect to the external synth's patch points, and use aftertouch and the mod wheel to modulate the external synth. You can also route the audio output of the external synth into the Matrixbrute as a 4th oscillator and send it to either filter or both, and to the envelopes. I used the Behringer 2600 and stacked together 6 oscillators. 

This Matrixbrute is in excellent condition, and will be shipped in its original box (with additional packing) along with User manuals plus additional material, the power cord, a USB cord, 2 audio cables, a midi cable, a 1/4" to mini-plug adapter for the head phone jack, and the patch program library list. I can also email the MS word template for the patch library if you want to make changes, and the entire library of sounds as an “mbprojz” file.
