For what it’s worth to you Jo,
The Prophet 12 really is a different DSI from what I heard after going through a lot of the presets and tweaking a bit. And keep in mind I have never liked most of DSI except for a couple Mopho and Poly Evolver sounds.
Though that digital harshness most people associate DSI with is still somewhat noticeable, it had some really nice 12 voice unison mode patches, that were as fat and booming/slamming as a Jupiter 8 if not fatter… and made you really forget it was DSI at all at times. All 12 voices light up at the same time on the panel in unison mode and it really is a cool experience to play with that kind of power/sound from a machine.
It had a very different unique sounding set of string and pad sounds, as well as some very pretty high tone bells and plucked timbres that I have not heard from any other machine available up until today. I would like to get the module at some point and I hope it is all I heard those first few times.
You could always wait it out until the price drops
Best
