I have a beloved vintage Mono-Poly that has been my analog keyboard of
 choice for live performance for many years. I need three replacement
 keys, specifically E, F, and F#, thanks to a clumsy roadie. Any help
 would be most appreciated. I have 4 Moogs (Mini, Micro, Multi, and
 Poly), but I prefer the Mono-Poly to all of them for live performance.
 The wonderful arpeggiator gets a lot of use. The Mono-Poly is perfect
 for reproducing vintage VCS-3 Pink Floyd sounds (especially the synth
 solo on "Run Like Hell"), and I prefer the pitch and modulation wheels
 to the Moog touchstrips. I don't have a lot of patches set in stone;
 I use the "change the cutoff and resonance on the fly" technique more
 often than not. Again, any help you can offer concerning the keys
 would be most appreciated.
 Thanks, Joe
