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-1 Output Expander. Up to 64 extra 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.

Typical usages

With a MIDI keyboard

Up to 16 note polyphonic conversion, with optional pitch/gate/velocity etc. CVs per note. Also features arpeggiation, keyboard splits and more.

With an MPE controller

Up to 16 simultaneous touches converted with full position/pressure/glide etc. per touch.

With a MIDI controller

Up to 64 outputs. Direct control of CVs from faders, flexible and syncable LFOs, triggers from pads etc.

With a ‘groovebox’

Multiple clock outs at different divisions, run/stop triggers etc. Groovebox, FH-2, or another module can be the clock master.

With a computer/tablet/phone

All of the above, plus SysEx for configuration of the FH-2.

As a clock generator

The FH-2 can operate as the clocking centre of your modular, also generating (syncable) LFOs, with no USB connection.
