INTRODUCTION

The Freq 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 Freq 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 channels of liquid FM sounds, it plays great by itself or synced with your favourite external gear.

VOICES

• 2 independent 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, Saw, Reverse Saw, Square, Noise, Off
- Attack/Decay modulation envelope per voice
- LFO per voice with multiple waveforms and selectable destination: envelope attack, decay & depth, FM ratio, note length or modulation level

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

• Audio output (16KHz 14-bit DAC)
• Sync input / output (0-5V rising-edge)
• Powered by an Arduino Nano V3
• 112mm (w) × 100mm (d) × 40mm (h)
• 7-12V DC or micro USB powered.
• Current draw 300mA @ 12VDC

OPERATIONS MANUAL

DISPLAY

SOUND SYNTHESIS

VOICE SELECTION

• Press [VOICE] to toggle between the two voices
• Press [FUNC]+[VOICE] to toggle Control-All mode to control both voices at once

OCTAVE

- Hold [FUNC] and turn [AMP DECAY] to set the octave for the current voice

MODULATION ENVELOPE

- Use the [ATTACK], [DECAY] and [DEPTH] controls to set the shape and intensity of the modulation envelope

FREQUENCY MODULATION RATIO

• Turn [FM RATIO] to control the ratio between the carrier and modulator
• Hold [FUNC] and turn [MODE] to access different multiplier modes for the ratio

Quantised multiple

Un-quantised multiple (high range)

Un-quantised multiple (low range)

Unrelated

- Hold [FUNC] and turn [ATTACK/CARRIER] or [DECAY/MOD] to control the waveform of the carrier or the modulator

LFO

• Turn [LFO DEPTH] to control the intensity of the LFO
- Hold [FUNC] and turn [LFO RATE] to control the speed of the LFO
- Hold [FUNC] and turn [DEPTH/LFO] to change the waveform for the LFO\
- Press [FUNC]+[LFO ->] to control what parameter is affected by the LFO

SEQUENCER

• Press [START] to start the sequencer running
• Hold [FUNC] while tapping [START] to set the tempo. The Freq FM will average 4 consecutive taps

SYNC WITH OTHER GEAR

• The Freq FM responds to a rising-edge 5V trigger signal received on the SYNC IN jack.
- To control how many steps the sequencer advances, hold [FUNC] and turn [SEQ LEN]. The default value is 2 (Volca compatible).

MUTATION - HOW FAST THE SEQUENCE CHANGES

• More often: turn [ MUTATION] clockwise
• Less often: turn [MUTATION] anticlockwise
• Never: turn [MUTATION] fully anti-clockwise

DENSITY - HOW MANY STEPS HAVE NOTES

• More steps have notes: hold [FUNC] and turn [DENSITY] clockwise
• Less steps have notes: hold [FUNC] and turn [DENSITY] fully clockwise

LENGTH - HOW MANY STEPS IN THE SEQUENCE (SETTING IS PER VOICE)

• More steps (up to 16), turn [SEQ LEN] clockwise
• Less steps (down to 1), turn [SQL LEN] anticlockwise

MUSICAL TONIC & SCALE

• To change the scale, press [SCALE]
• To change the tonic, press [FUNC]+[SCALE]

ALGORITHM - HOW THE NOTES ARE GENERATED

• To change the generative algorithm, press [ALGO]

PARAMETER LOCKING

• Hold [REC] while moving a control to record that movement into the sequence
  is displayed when recording mode is activated
• Hold [FUNC]+[REC] while moving a control to delete all recorded parameter locks for that control
  is displayed when recording-delete mode is activated
