Expert Sleepers FH-2
The ultimate MIDI-to-CV hub for Eurorack
8 HP Eurorack module
The FH-2 'factotum' is a comprehensive MIDI-to-CV converter and clock generator for Eurorack, capable of converting USB MIDI, USB host MIDI, and 5-pin DIN MIDI into up to 64 control voltages via expansion modules. It supports monophonic, polyphonic, and MPE conversion, flexible LFOs, arpeggiators, Euclidean pattern generators, envelopes, and extensive clocking features, making it a powerful hub for integrating MIDI devices with modular synthesis.
Features
- MIDI-to-CV conversion: monophonic, polyphonic (up to 16 voices), and MPE
- 8 onboard CV outputs with 14-bit DAC resolution
- Expandable to up to 64 outputs via FHX-1 expander modules
- USB A host port: connect USB MIDI devices and hubs directly
- USB C device port: connect to computers, tablets, phones as USB MIDI device
- 5-pin DIN MIDI input and output via expansion header (GT3)
- FH-1 module usable as expander via USB A to USB C cable
- 32 clock generators with configurable rate, pulse length, shift, and type
- 32 trigger generators responding to MIDI notes
- 16 MIDI/CV converters active simultaneously
- Per-output LFOs with 7 waveform shapes (sine, square, triangle, saw, random, noise) and phase control
- LFOs can run in Hz mode or tempo-synced mode
