The Mutant Machine dynamic analog percussion synthesis engine v1 05 HEXINVERTER NET Thank you for your interest in the Mutant Machine MM The Mutant Machine is a 29HP eurorack format synthesizer module It requires the use of a eurorack format case and power supply to work A MACHINE IS BORN The Machine began as a quest to create a rich sounding eurorack snare drum synthesis module to complement the existing Mutant Drums The project quickly became too large and costly to justify the module being capable only of snare drum sounds So the decision was made to learn from the architecture of the TR 909 s snare and kick circuits in order to develop a module capable of generating multiple forms of analog percussion and various other effects Like the other Mutant Drums the Machine has its roots in classic analog percussion synthesis Even though it can create totally alien sounds it still has the capability to deliver those classic 909 house snares and kicks if you want them There are no microcontrollers in the Machine The signals and waveforms are all generated by discrete components and ICs for a distinctly analog sound and user experience FEATURES microcontroller free analog percussion synthesis engine unique Inverter Core oscillators form the MEMBRANE Each analog oscillator has three waveforms to select from e capable of synthesizing everything from heavy hitting bassdrums to classic 909 style snares and other complex timbre
3. alog system MEMBRANE ARCHITECTURE e The MEMBRANE forms the main body of the sound by way of two analog oscillators each offering three waveforms to select from e The analog waveforms can be selected manually by button press or the WAVESCANNER can be used to automatically scan through the available waveforms By modulating the frequency which waves are scanned at complex timbres are created e The scanner can be gated on and off via CV or gate with the ENABLE input e An external audio source can replace WAVE 1 in the signal path if a signal is patched into the WAVE 1 audio input PITCH CV SNAPPY DECAY CV SNAPPY SNAPPY OUTPUT SNAPPY NOISE DECAY LEVEL DRIVE GENERATOR CLICK SNAPPY GENERATOR CLICK NOISE OUT SNAPPY IN 01 29 2015 Mutant Machine user manual v1 05 PG2 hexinverter net electronics 2014 SNAPPY ARCHITECTURE e The SNAPPY generator features a voltage controlled noise oscillator reminiscent of vintage 8bit computers Small variations in pitch can produce dramatic changes in the overall sound produced by this unique oscillator e This section of the Machine complements the MEMBRANE by adding a decaying noise element to the mix The decay is voltage controllable e The CLICK generator derives its sound from the same source as the SNAPPY but its volume is adjusted independently e Should you tire of the internal noise generator virtually any sound source can be injected into the signal path by plugging into the SNA
