Straightforward ADAT conversion


Optx is a compact and bi-directional ADAT lightpipe converter for eurorack synthesizers. The module provides 8 channels of input and output expansion to many pro audio interfaces, and may be used standalone for noise-free interconnections between eurorack systems.


ADAT Encoding & Decoding


Some computer audio interfaces are equipped with one or more pairs of ADAT expansion ports allowing for additional input and output channels. Optx takes full advantage of these often unused ports, providing multi-channel connections directly to and from eurorack systems.


The module accepts any 8-channel ADAT encoded digital signal at the Rx TOSLINK jack (via lightpipe optical cable) and converts it into 8 discrete analog signals available at the OUT 1-8 jacks.


Conversely, Optx accepts 8 discrete analog signals at the IN 1-8 jacks and converts them into an 8-channel ADAT encoded digital signal available at the Tx jack.


DC-Coupled I/O


All of the module’s analog connections are DC-coupled, meaning signals can be AC (audio) or DC (control voltages). So when used in conjunction with software such as Bitwig Studio or Ableton CV Tools, Optx becomes a bi-directional interface for control voltages like 1V/oct pitch and gate signals, or LFOs, ADSRs and other modulators. the amount of creative potential here cannot be overstated.


Computers and software are not needed to take advantage of DC-coupling. When used standalone, both audio and control voltage signals can be sent between Optx modules.


Sample Clock Synchronization


The module has three options for sample clock sync, selectable using the 3-way switch.


44.1 Generates and syncs to internal clock of 44.1 kHz


EXT Syncs to external clock from ADAT signal at Rx


48 Generates and syncs to internal clock of 48 kHz


Signal LEDs


Optx also provides visual signal indication of the 8 decoded ADAT channels feeding the OUT 1-8 jacks. Each pair of WHITE LEDs indicates the polarity (-Ve left, +Ve right) and relative strength of the signal (± 10 V).


Audio-rate signals will generally light both LEDs continuously, whereas LFOs will alternate more apparently between the two. Gates, triggers and positive-going envelopes will generally light only the right LED (+Ve).

patch tips


CV/GATE/MOD & AUDIO RETURNS – Use CV capable software such as Bitwig Studio or Ableton CV tools to send pitch, gate, and modulation signals to Optx outputs. Patch them respectively into a 1V/oct oscillator, envelope gate input, and filter cutoff control. Then patch the audio signal(s) back to the Optx inputs to mix within the DAW software. Instrument tracks can then contain both the sequence data and audio returns for simple and powerful integration with your eurorack synth.


NOTE: 1V/oct signals will require calibration within the software.


DRUM TRIGGERS & AUDIO RETURNS – Using a drum rack in one of the aforementioned CV capable softwares, send up to 8 drum triggers to Optx outputs. Patch them into trigger inputs of drum modules, envelopes, etc. Now patch their respective audio signals back to Optx inputs to mix and process within the DAW.


NOTE: Some drum modules are responsive to varying trigger voltage. If the trigger CV output level is modulated using velocity/etc in the software, then Optx will dynamically produce trigger voltages based on velocity!
