Dave Smith Instruments SYNTHESIZERS

I am very sad to say that my Evolver has stopped functioning correctly.  I am very good at 
program this synth so I know that no LFOs and the third envelope are turned on.  The 
transpose and fine tune are also at zero.  So my problem is that when I have the 4-pole on 
and all oscillators at zero, with the resonance at 100, I get a strong beating where the 
resonance will go up in down in timbre and this will speed up as I go up the keyboard.  I 
have an example I recorded, but I don't know where to post it..so anyone who wants to 
help and hear the example please email me @ sdanuser@... and i'll send you the 
audio file.  I don't know what to do..it was working fine yesterday!

Thanks everyone,

Scott
