"Rev 3.2 Prophet 5 with full midi installed (including rare velocity sensitive functionality not found on all midi prophet 5's )Now i should make it clear that the difference between this and a rev 3.3 is 80 memory locations But i should also state that this can be upgraded to 3.3 rev status very easily by replacement of a chip in the prophet 5 which mosy synth techs can do ( its outlined how to upgrade a 3.2 to 3.3 in service manuals ) and also that the 3.2 and 3.3 are identical in every other way .A 3.2 is a 3.3 without the larger memory chip...
Ok so now the sound , i dont need to talk it up , these things sound legendary , fat , warm , creamy , resonant , all words used a million times to describe analogue circuits but seriously if you havent heard a real prophet 5 then it is a bit of a heartmelting experience , every range of sounds it does its stunning , the low end is smooth and the highs crystal clear and when you dial in the unison mode it can blow your speakers apart if your not carefull , its resonant filter and the osc sync combined make the most incredible metalic harmonics which sing , they dont 'resonate ' they sing and this is one of the most subtle and beautifull synths you can buy.Its range of sounds is wide, the prophet 5 was used for many star wars fx and Pads and the ambient spaces in the film , its a blinding machine for ambient work but equally good for mean dance music , it can be off the wall or do all those classic 80's sounds.Yellow magic orchestra and Peter gabriel , Japan , you name them , they used one and dialing through the presets gives an instant ' so thats where they got ' that' sound ' experience..."
