On checking this 'smaller keys' issue, I found that the key's are normal synth size 'BUT' each key's side edges have been chamfered slightly thus reducing the key's playing surface area giving the appearance of a smaller key.

I have an Evolution MK461C 61 note MIDI controller keyboard and the GW-7 was almost an inch longer in total keyboard length.

Maybe It's time to make a sheet containing all brands and models with keysize which could be placed somewhere on synthzone by Nigel.

thanks pasadouble, i really appreciate it
