The FH-1 ‘faderHost’ is a USB MIDI Host in an 8HP Eurorack module, allowing you to directly connect a USB MIDI controller to your modular synthesizer. Using a suitable connector box, “USB MIDI controller” here includes an iPad or plain old computer. As well as simple direct control of the output CVs from MIDI CCs, the FH-1 also offers LFOs on each output, step sequencers, polyphonic, MIDI/CV conversion, and much more.

The front panel is drilled for both Doepfer and Analogue Systems mounting holes (using a ‘slot’ rather than a single round hole). The power connector is a Doepfer standard 10 way IDC, with -12V furthest from the top of the board.

Specifications

• Current draw: 70mA on the +12V rail, 30mA on the -12V rail (100mA total) plus the power requirement of the attached USB device.
• Outputs: 8
• Digital-to-analogue conversion: 14 bit
• Inputs: 2 digital inputs for clocks etc.
