8 channel random voltage generator, with per–channel looping & attenuator controls in 8HP.

RANDOM8 is an 8 channel random voltage generator, with: Looping & evolving, attenuator, pitch quantiser, probability, clock divider, slide, offset, and selectable random voltage styles per channel.

RANDOM8 is designed to bring any sized eurorack system to life and help people perform and jam music more easily. It can provide subtle per-step modulation, allowing phrases to play for longer without the ear tiring of them. It can provide up to 8 quantised pitch generators (or any combination of pitch and modulation) and provide automatic melodies for a whole system.

Feed the inputs triggers, and for every trigger, you get random voltages at the red output sockets on that channel and below it. Users can insert additional triggers into lower-down channels to break the normalisation and create groups of voltages. There is an output attenuator for each channel controlled with a trim pot.

By pressing a button, channels go from random to looping. Press again, and the channel is evolving, where voltages in memory change slowly over time. If users like the evolution, they can press again, and now that phrase is locked, until they press again. To return to full randomness, double tap the channel button.

Additional features are contained in 8 menus which are all one layer deep. Hold a button for 1 second, let go. Lights confirm you are in the menu that corresponds to the label. Now turn any of the 8 dials to edit that menu setting for any or all 8 channels at once. Only the controls you interact with will change. Push any button to exit the menu and return to looping and evolving.

Introductory video:

• 8 channels of random looping CV generation in 8HP with per-channel attenuators and looping buttons.
• Cycle between looping and evolving voltages with a single button press. Double click to return to random.
• Cascading normalised triggers to create groups of voltages.
• Pitch quantiser per channel with 16 options (unquantised, 14 scales, 1V steps scale).
• Looped phrases can have step length from 1-32.
• Input trigger divider per channel, letting 1-8 triggers advance each step.
• Per channel probability to make voltage changes less frequent.
• Slide for creation of LFOs, slow evolving voltages and acid lines.
• Offset to raise voltage range and 'clip' voltages to the ceiling.
• 8 preset locations to save and recall entire module state.
• Simple one-layer menu system designed by someone who dislikes menu systems.
• Distinct and considered LED colours in menus aid with visualising settings.
• Long press buttons to reset channels or whole module conveniently.
• 0-10V unipolar output voltage.
