Hi @Vincent,
just a fast guess:
The OB-6 can send SYSEX dumps? So a way may be:
- Get a SYSEX dump
- Convert it to LV2 (Parameters like Obxd.ttl).
@Baggypants (AFAIK) has written a cool tool for converting such dumps for Dexed/DX7 and others. This may also work for other synths. See LV2 presets & converters for Rapho, Synthv1, Padthv1
