I got this PG-10 synth controller to use on my Roland D-10 Synthesizer. It works great and is good condition. There is aÃÂ cap missing from one of the slider controls but does not detract from it's functionality. It is my understanding that these controllers were used on a few Roland synth models. I am selling this unit as I may not alter any of the existing sounds on my D-10 any longer. I am mixing the preset tones with some software based synth sounds on all my vintage synths.ÃÂ I may also listÃÂ the D-10ÃÂ here as well, I haven't decided yet. Feel free to email with any questions.
