Description:

Up for sale: a Teenage Engineering Oplab, the discontinued MIDI/USB/CV/Sync24 experimental interface board. Fully tested and working.

The Oplab is TE's hacker-friendly junction box for getting analog, MIDI, and USB gear talking to each other — no computer required. It ships and is meant to be used exactly like this: as an exposed board, no enclosure.

Features:

• 2x USB host ports (A/B) — plug in OP-1s, pads, or class-compliant USB MIDI controllers directly
• MIDI in/out (5-pin DIN)
• Sync24 / DIN sync output — sync vintage gear like the TB-303, TR-606, and other DIN-sync sequencers
• CV1/CV2 + gate ins and outs on 3.5mm jacks
• CV out switchable between Hz/V and V/oct
• Gate out switchable between gate and s-trig
• 10-position rotary switch selecting between 10 operating modes (single source, single destination, USB merge, clock master, jack sync, sensor/CV-to-MIDI mode, and more)
• A / B / Select buttons for routing and playing notes
• Per-port LEDs plus 4 mode-indicator LEDs

Great for bridging USB MIDI gear with vintage analog synths/drum machines, or as a MIDI-to-CV converter for a modular setup.

Included: Board only — no power supply, box, or cables. Runs on 5V DC (standard 5.5/2.1mm barrel, 2A) or can be bus-powered over its USB device port from a computer, so any compatible 5V USB power supply works fine.

Condition notes: Board shows normal handling wear consistent with age; all ports, switches, and jacks function correctly. Tested working across MIDI, USB host, CV/gate I/O, and Sync24.

This is a discontinued TE product and doesn't come up for sale often — grab it while you can.
