Introduction Congratulations on your purchase of an Expert Sleepers FH-2. Please read this user manual before operating your new module. The key functions of the FH-2 are • MIDI-to-CV conversion, or more generally, generating CVs in response to MIDI messages.
Typical usages With a MIDI keyboard MIDI Clock 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 MIDI Up to 16 simultaneous touches converted with full position/pressure/glide etc. per touch. With a MIDI controller Power MIDI...
With a 'groovebox' Clock Clock MIDI 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 Clock Clock MIDI SysEx All of the above, plus SysEx for configuration of the FH-2. As a clock generator Clock The FH-2 can operate as the clocking centre of your modular, also generating (syncable) LFOs,...
Installation House the module in a Eurorack case of your choosing. The power connector is Doepfer standard If using the power cable supplied with the module, the red edge of the cable is furthest from the top edge of the PCB, and carries -12V. ("-12V" is marked on the PCB itself next to this end of the connector.) Be sure to connect the other end of the power cable correctly, again so -12V corresponds to the red stripe on the cable.
and its function is as follows: • Jumper across pins 1 & 2: take USB power from the FH-2's own regulator • Jumper across pins 2 & 3: take USB power from the Euroack 5V bus. Needless to say, to make use of the second option your Eurorack PSU needs to be one that supplies 5V in addition to the usual ±12V.
From here on these will be referred to as 'the encoder' and 'the left button'. Display Modes The FH-2's display is usually in one of a small number of modes. Overview This is the FH-2's default display mode. At the left of the screen are activity indicators for the possible MIDI connections: •...
Edit screens Many menu pages which allow you to edit configuration or preset parameters share a common way of working, illustrated here with the Preset/Edit preset/LFOs page. The rectangle is the 'cursor'. When the cursor is drawn using a dotted line, turning the encoder moves the cursor between items –...
Clocking All clocking in the FH-2 is in terms of 24ppqn (pulse-per-quarter-note) pulses. This is the rate used by MIDI clock messages, and also by the analogue DINsync standard. Thus if for example an LFO rate is given as '24' it means it will cycle at the speed of quarter notes; '12' means an eighth note etc. When using the FH-2 to bridge between analogue and MIDI devices, in either direction, if possible choose 24ppqn clocks (i.e.
Save configuration The 'Save configuration' menu allows you to select one of the configuration slots, displaying its number and the name of the configuration stored in that slot. Pressing the encoder shows the message 'Are you sure?' - press the encoder again to save the current configuration into the selected slot.
Reset preset This menu allows you to reset the current preset to default values. It has no effect on the presets in flash memory. Name Preset This allows you to edit the name of the current preset. Typically you would do this before saving it to flash.
The top item lets you select the output you want to edit. The centre item lets you set the 'centre' CV, which will be 0V if the output range is set to ±5V. It corresponds to MIDI note 60 (C4). The lower item lets you set the '+3 octaves' CV, which should output 3V more than the centre CV, or in terms of pitch, a note 3 octaves higher.
Configurations A configuration consists of the following: • the configuration name • some global settings (trigger length, global transpose etc.) • setup of the MIDI/CV converters • setup of the MIDI CC assignments ('mappings') • setup of the Clocks • setup of the Triggers •...
considered to have stopped. • "Run/Stop on Y" (1) – the Y input is used as a DINsync-style run/stop control. The clock runs while the signal is high, and stops when it is low. Tap Tempo Tap tempo can be controlled via the front panel button (if configured in the Settings) or via an incoming MIDI note or CC.
Name Value Description range Base output 1-64 The base output of the converter. (Outputs 9-64 are expander outputs.) Stride 0-32 Sets the spacing between the per-voice sets of CVs. For example, if a polyphonic converter has just CV and gate per voice, and a base output of 1, then the voice outputs will be 1/2, 3/4, 5/6 etc.
Polyphonic Expression or MPE . An MPE converter receives on a number of MIDI channels. The Channel setting is taken as the MPE 'global' channel, so the voice channels will begin one channel up from that. The last channel to receive on is set by the Last Channel setting.
Voltage range Each output of the FH-2 can be switched between a voltage range of 0-10V and ±5V. The same is true of the FHX-1 expanders, but for the FHX-1 this is done via a physical jumper on the module, rather than being software-configurable. Clocks There are 32 clock generators available.
Euclidean Patterns Most of the Euclidean Pattern setup is in the preset – see below. The configuration only defines the output that each pattern generator uses. Gate levels Two values define the low and high output values to be used if the output in question is used as a gate, clock, trigger etc.

The left box is a log of messages reported by the tool. The centre box shows the last SysEx message sent by the tool. The right box shows the last SysEx message received by the tool, and in the case of the Message SysEx message, the actual message as plain text (“v0.0”...
Presets A preset consists of the following: • the preset name • the internal clock tempo • for every output: • the direct output levels • the LFO state • the smoothing amount • for every MIDI/CV converter: • the arpeggiator state •...
Name Description Speed Sets the LFO speed, from 0.1Hz to 10Hz. A logarithmic scaling of the value is used, to allow finer control over the slower end of the range. A 14 bit quantity. Tempo Base The rate of the LFO, in terms of 24ppqn pulses. Tempo Mult Multiplies the 'Tempo Base' to give the actual LFO rate.
Arpeggiator Each MIDI/CV converter of the FH-2 has an arpeggiator. The controls are as follows: Name Description Arp Mode Mode - see below Arp Range Range - the number of octaves to repeat the arpeggiation pattern over. When mapped, CC values 0-127 map to 1-3 octaves. Arp Gate Len Gate length - the gate on time as a fraction of the clock rate.
Calibrations In addition to the basic calibration offered in the settings, above, the FH-2 can also perform an automatic calibration process much like that in the Expert Sleepers Silent Way software . This is accessed via the top-level menu item Calibrations.
through a rising set of pitches. As the calibration runs, the FH-2 will draw a graph, which ideally will end up looking something like this: This shows pitch (horizontally) versus voltage (vertically). The steepness of the curve indicates the V/octave response of the VCO; the image above shows 1V/octave (the usual standard). For comparison, an approximately 1.5V/octave response looks like this: Note that the pitch range is less, since less octaves fit into the FH-2's output range.
Name calibration This allows you to edit the name of the calibration you are about to save. Editing the calibration name works in the same way as editing the configuration name, above. Page 27...
5-pin DIN MIDI I/O The FH-2 has an expansion header on the PCB which can be used to add a pair of traditional 5-pin DIN MIDI ports to the module (one input/one output). This is compatible with the Expert Sleepers MIDI breakout Connections The MIDI ports are exposed on a 4-pin expansion header (labelled GT3) on the lower PCB.
All SysEx messages are prefixed with a manufacturer's ID, which is a unique series of hex bytes assigned by the MIDI Manufacturers Association. The Expert Sleepers ID is 00H 21H 27H, so all SysEx messages relating to Expert Sleepers hardware will begin...
22H – Request version string F0 00 21 27 2F 22 F7 This causes the FH-2 to respond with a SysEx message containing the module's version string as text, using the '32H – Message' format, below. Sent SysEx messages 10H – Install script See above.
The FH-2's firmware can be updated using a USB flash drive, which must be formatted as 'FAT' (variously referred to as 'MS-DOS FAT', 'FAT16', 'FAT32'). The process is as follows: • Download the firmware from the Expert Sleepers website. • Unzip the download.
