Pyxis LFO

The Pyxis Wavetable LFO is a Eurorack module built around a 32 bit ARM microcontroller, rather than more traditional analogue technology. This means that it is able to offer a far more flexible take on modulation than most current Eurorack LFO modules, rivalling the capabilities of even some modern software virtual instruments.

The heart of the module is a wavetable scanning oscillator; this allows for smooth “crossfade” between a sequence of four waveforms, allowing an unparalleled number of wave shapes. With user definable waveform sequences, complete control over ordering, phase, and repetition, this is a massively flexible module.

Features

• Wavetable scan between sequences of up to four waveforms; define custom wavetables from 9 waveforms, with control over multiplier and phase of each entry in the table; the picture below shows such a sequence: The animation below shows the effect of scanning through the resulting wavetable:
• Three switchable frequency ranges:
• 0-1 Hz
• 0-10 Hz
• 0-100 Hz
• Voltage control over wavescan, frequency, phase.
• Attenuverters on all voltage control inputs; complete control over the effect of incoming control signals.
• Retrigger and/or clock input; quantise the LFO output to either an external or internal clock source, for tempo synced modulation effects. Retrigger allows the module to act as an envelope generator.
• OLED screen provides intuitive visual feedback on the current state of the oscillator.
• High performance ARM microcontroller; hardware floating point DSP, 22khz sample rate, 12 bit ADC/DAC resolution.

Tech Specs

• 14HP wide
• 25mm deep (measured from front of faceplate to top of tallest component on the back).
• Requires 25mA on the -12v rail, 75mA on the +12V rail. No 5V rail used.
