The GliGli firmware (versions 2.0 and 2.1RC3) re-designated the original "Mixer" and "Glide" of the Prophet 600 knobs to control the volumes of oscillators A and B separately. This has the disadvantage that the glide amount needed to go into the - not very user friendly - parameter menu. On the other hand with the GliGli layout, one could (over-)drive both oscillator A and B amps. Personally, I also appreciate the clarity of controlling the two volumes with the two knobs, conveniently positioned next the oscillator sections. There are obviously good reasons for either choice of layout. Now, I have had requests from several users that the original Sequential Circuits layout be brought back. I even had one collector who said he refused the GliGli upgrade because he didn't like the fact the panel control descriptions don't match the control function. And he has a point - not many people got hold of a synth graphics panel overlay to match the GliGli upgrade and
