The Expert Sleepers FH-2 is an 8HP Eurorack module combining the following functions:

MIDI to CV conversion including polyphonic and MPE operation.

  • The FH-2 is simultaneously a USB MIDI host, a USB MIDI device, and also supports traditional 5-pin DIN MIDI.
  • Support for drum triggers including triggers with velocity or accents.
  • Support for automatic VCO calibration (similar to that in Silent Way).

Clock generation and synchronisation.

  • MIDI clock (in and out), analogue clock (in and out), or internal clock (BPM or tap tempo).

LFO generation (including tempo-synced LFOs) Arpeggiators & Euclidean pattern generators.

The FH-2 has 8 high precision CV outputs, expandable to 64 with the FHX-8CV Expander. Up to 64 additional gate/trigger/clock outputs can also be added with the FHX-8GT Gate Expander.

The module can be completely configured via its own UI, but a convenient web-based configuration tool is also available here, which communicates with the module directly via MIDI SysEx.
