Rigged up the Machinedrum with a couple of pedals…
The bassdrum goes through output F to an Octave Multiplexer and then to a Blackstar HT-Metal preamp/tube-overdrive pedal
The hihats go through output E to an Electro-Harmonix Stereo Electric Mistress Chous/Flange/Resonant Filter pedal
Using a Behringer analog portable two track mixer to combine the signals of the Machinedrum (main input with 2 band graphic eq and preview button), flanged hihats from the Electric Mistress goes to the microphone input (with the mic gain trim turned all the way down) - this input also provides a two band-range eq, albeit with no preview button.
The output of the tube overdrive/clean preamp pedal is converted into a parallel signal on two rca leads that then feed into the 2-Track input of the Xenyx minimixer.
the output of the Xenyx mixer goes to a stereo rca input of the soundcard.
Makes for quite an attractive array of sound design options, without taking up a huge amount of extra space.
