[sdiy] Rack Mounting OBX Voice Cards as Modular Synth Modules?

[Wheaton, Simon]

I bought 4 OBX voice cards, purchased for about $50US each.

 

The plan is to mount them behind panels as modular synth modules to
connect to my Roland System 700, MOTM and Fenix.

 

Has anyone done something similar?

 

Is there any info on this sort of thing up on the web?

 

Is there an OBX service manual/schematics online somewhere?

 

Any ideas/tips on doing this sort of thing?

 

I was thinking of putting each voice card behind it's own Schaffer
panel, with separate power supplies per panel.

 

Do I need to buffer the inputs/outputs?

 

Do I need to have some extra circuits providing certain voltages, and
some control over those voltages, or would they all come from other
external modular modules?

 

Does anyone know what sort of control voltage ranges the different
inputs of these voice cards expect?

 

It's a long term project, so no rush on it, but I would like to get it
all running right before buying front panels.


I also have 3 SEM modules that I plan to do similar rack mounting to,
along with a mini-sequencer (and plan to buy a 4th SEM and 2nd
mini-sequencer to go with these).

 

Thanks,
Simon
