I am a great fan of Vintage synths and Wind Controlers I have had Yamaha WX7 and 5 and I now have both EWI 4000s and 5000 (also a new Aodyo Sylphyo).
I would lie to make some modifications on my EWI's to integrate Wireless MIDI and make some other changes
I am trying to get the service manuals of the 4000s and 5000 so I would be grateful if someone could share them with me.
Thanks a lot for your help
Kind regards
Fred
