• Early design to present day information
This is one of my early midi system designs which is now obsolete. I've found that most accordion users select the sounds from a sound module like a Ketron SD3. My new design is simple with options for volume controls. I can also add pressure sensor volume controls and effect controls like reverb or vibrato.
• Repairs, tuning and restoration
There's not many problems I can't repair. Replacing keytops, bellows corners, bellows straps, left hand straps, grill cloth, reeds, pads, valves, key stems, button stems, etc. Electronics repairs on Musictech, Ketron, Orla, Iorio, Elkavox Orla, Roland, Yamaha, Korg products. The advantage you will have with my services is that I can repair the acoustic and the electronics in your accordion. I am an authorized Roland, Yamaha repair tech.
