Freaq FM 8-bit Generative FM Synthesizer
Wirehead Instruments’ Freaq FM is an 8-bit digital synthesizer for your desktop featuring dual FM voices paired with a 2-track generative sequencer.
From soul-soothing sine waves to multiverse-shredding modulated distortion, slapping bass lines to soaring arp leads, the Freaq FM is a powerhouse of sound design packaged with a melodic and intuitive generative sequencer inspired by the likes of Elektron, Intellijel & Music Thing.
With 2 independent liquid FM voices each with user-controllable waveform, modulation envelope and LFO all integrated with a 16-step generative sequencer, it plays great by itself or synced with your favorite external gear.
Voices
-
2 independent 8-bit FM voices
-
2-operator FM (for old-school prince of persia vibes!)
-
Multi-mode FM ratios - quantised, free-multiple, independent
-
Multiple operator waveforms for carrier & modulator - Sine, Triangle, Overdriven triangle, Saw, Square, Noise, Off
-
Attack/Decay modulation envelope per voice
-
LFO per voice with multiple waveforms and configurable destination: modulation envelope (attack, decay or depth), FM ratio, note length
Sequencer
-
2/1.5 track polymetric sequencer with up to 16 steps per track (Both tracks use same note sequence but can have different step-counts for poly-metric rhythms)
-
Multiple generative algorithms - (semi)random notes, (semi)random runs, arpeggio, drone
-
Sequence mutates/evolves at user-defined rate & note-density
-
Selectable tonic, octave & scale - Ionian (Major), Minor (Dorian), Pentatonic, Phrygian (GOA!), Octaves, Fifths
-
Tap-tempo control
-
Sync input & output (Korg Volca compatible)
-
16-step parameter-lock recording of synth parameters (track 1 only)
Hardware
-
Mono audio output (16KHz 14-bit DAC)
-
Sync input / output (0-5V rising-edge)
-
Powered by an Arduino Nano V3
-
112mm (w) x 100mm (d) x 40mm (h)
-
7-12V DC or micro USB powered

Parameter Locks Per-step parameter locks: Note length LFO depth FM Ratio Modulation envelope attack, decay & depth Parameter locks apply to track 1, but are recorded into the track with the longest sequence length. For example, if Track 1 has 3 steps and track 2 has 16 steps, you will record a 16-step parameter-lock sequence which is applied to track 1 |
