MIDI-to-CV converter with 8 outputs, 2 inputs, USB host/device, clocking, LFOs, arpeggiators, Euclidean patterns, sequencers, shift register randoms, CV-to-MIDI, and preset storage.653
Capabilities 8
Arpeggiatorarpeggiator
Each MIDI/CV converter has its own arpeggiator with configurable mode, range, gate length, latch, rate, and reset. Supports multiple arpeggiation modes including up, down, alt, random, and as-played.653
CV to MIDI Conversioncv-to-midi
CV inputs can be converted to MIDI CC, Trigger (note on/off), Note (with gate input), Program Change, or Aftertouch messages. Output can be routed to any MIDI port or used internally.653
Clock Sourceclock-source
32 clock generators available. Can generate analogue clocks from MIDI clock, MIDI clock from analogue clocks, or clocks from internal clock. Supports tap tempo.653
Euclidean Sequencereuclidean-sequencer
Up to 16 Euclidean pattern generators with configurable pulses, steps (max 32), rotation, rate, gate length, accent rate, and reset. Can be controlled via Launchpad.653
LFOlfo
Each output has an LFO with sine, square, triangle, saw, random, and noise shapes. Speed can be set in Hz (0.1-10Hz) or synced to tempo. LFOs can fade in on retrigger.653
MIDI to CVmidi-to-cv
Supports monophonic, polyphonic (up to 16 voices), and MPE MIDI-to-CV conversion with configurable outputs for pitch, gate, velocity, aftertouch, pressure, trigger, envelope, bend, and random CVs.653
Preset Storagepreset-storage
30 preset slots and 30 configuration slots in flash memory. Presets store direct output levels, LFO states, smoothing amounts, arpeggiator states, portamento, transpose, Scala scale assignments, Euclidean pattern states, and sequences.653
Sequencersequencer
Four note sequencers and one drum sequencer. Note sequencers support up to 32 steps, multiple directions/permutations, ratcheting, and ties. Drum sequencer has 8 lanes of up to 32 steps. Designed for use with Novation Launchpad.653

Assignable CV/gate/clock/trigger output. 14-bit DAC. Voltage range software selectable.653
Rotary encoder with push button function. Used to navigate menus, select items, and change values. In overview mode, pressing enters the menu system; turning can be configured for tempo control.653
Push button to the lower left of the display. In menus, goes back up one menu level; holding for more than half a second exits the menu entirely. Function when not in a menu is configurable (Off, Start/Stop, Tap Tempo/Stop, Test FHX-8GT).653
LFO Speed
menu_setting
0.1Hz – 10Hz
Sets the LFO speed. Logarithmic scaling allows finer control over slower end of range. Setting this parameter switches LFO to Hz-based (non-tempo-synced) mode. 14-bit quantity.653
Swing amount from 0 (no swing) to 127 (maximum swing). Applies globally to clock outputs, Euclidean patterns, and sequencers driven from FH-2's internal timebase.653
Per-output voltage range selection. Options: 0-10V, ±5V, 0-1V, 0-5V, and 0-8V.653
