[sdiy] OBX-a Poly mod

[ulfur hansson]

hello list,

repairing my old obx-a (again) i am falling in love with this synthesizer (again).

i came across this matrix-synth post that features images of an obx-a fitted with a mysterious JL-Cooper mod, allowing for prophet-5 style poly-mod.

does anyone happen to have any information on the kits design?

...or if i should end up feeling brave and design a board to achieve something similar - any thoughts?

thanks y'all!
sincerely,
-úlfur
