The Yamaha AN1x Synthesizer mailing list

Hi, Jon I have noticed that when I switch the AN1x on after it being 
off for a while the edit indicator appears on the display screen 
even though I have not touched any buttons or knobs. That is when 
the strange behavour of the VCF cutoff happens and the sounds act 
strange. The OS version of my AN1x is v1.02.
