Using MatrixBrute as an external audio processor
Is it easy to set up?
It is indeed. The MB is one of the finest external audio processors around (plus you happen to get a super-versatile analogue paraphonic synth in with the deal too)! We use ours for distorting drums and adding colour, plus the all-analogue BB (bucket brigade) effects sound great on anything, like having a suite of Moogerfoogers in one machine! Take the instrument you want to process, a jack lead (mono) and then set things up as follows…
Around the back of the MatrixBrute you’ll find a section labelled audio in. Plug in your audio source here via a mono jack lead. You can choose from a line level source or instrument level (guitar/bass/etc) via the switch. You also have a gain control to boost or cut.
Next start from an init preset by pressing Panel + Preset. Now in order to hear your external audio come through the mixer, you need to turn up the mixer’s external level dial and route that to one or both filters using the filter select button next to it.
Start your drum machine or play your instrument and hit any key or engage key hold to open the envelopes (make sure you have attack to fastest, plus decay and sustain at full on the amp envelope to start off with). You should now hear your audio through the MB!
If you want the envelopes to open without pressing a key, switch audio gate to on (via the rear panel switch) and the envelopes will open automatically when receiving audio. You can now use the envelopes, filters, effects and envelope follower in the matrix to process audio.
