Mutable Instruments Peaks Eurorack Module is designed for Eurorack synthesizer systems and occupies 8 HP of space. It requires a -12V / +12V supply (2×5 connector), consuming 2mA from the -12V rail and 60mA from the +12V rail. The red stripe of the ribbon cable must be oriented on the same side as the “Red stripe” marking on the printed circuit board.
Peaks is a multi-function module, but the general rule is that cool things happen whenever a trigger is received. Its four main functions are:
- Envelope generator – the gate/trigger input starts and holds the envelope.
- LFO – the gate/trigger input resets the waveform cycle.
- LFO with tap-tempo synchronization – the gate/trigger input sets the period of the LFO oscillations. Note that Peaks can “learn” irregular trigger sequences and lock onto them.
- Drum generator – the gate/trigger input triggers the drum sound.
Peaks provides two channels of processing – each of them has a gate/trigger input jack, a gate/trigger button with an output indication LED, and an audio/CV output. Both channels provide the same function – the exception being channel 1′s drum generator being a bass drum generator, and channel 2′s drum generator being a snare drum/hi-hat generator.
Both channels can be “synchronized” (aka twin mode), in that they both share the same front panel controls – for example in ADSR envelope mode, the first knob will control both channel 1 and channel 2′s attack time. This can be used not only to create duophonic patches (for which you actually want both channels to behave similarly), but also to obtain two synchronized outputs of the same LFO waveform with different phase shifts…
Another way of controlling the module is the split mode in which the potentiometers 1 and 2 control channel 1′s settings; and the potentiometers 3 and 4 control channel 2′s settings. This mode only gives access to the 2 most essential parameters of each function (for example attack and decay time for an envelope) – the other parameters being set to default “neutral” settings.
Finally, if breaking the one knob per function rule is not a taboo for you, an expert mode allows individual control of channel 1 and 2.
