I have Prophet 6 and Prophet 12 desktops, a Prophet X and an Analog Four.
Prophet 6 is pure analog bliss, one giant sweet spot and so easy/intuitive to use.
Prophet 12 is a lot deeper, fulfills all my needs for digital, has a lot of character and can also sound analog. Definitely gives me sounds that I cannot get ITB. Has a narrower sweet spot, but everything is so well laid out for deep sound design. For me the P6 and P12 are a match made in heaven.
I was a bit underwhelmed at first by the sound of the Prophet X and to me it seemed to have less character than the Prophet 12. However, I’ve been spending more time with it recently and loving it. With a bit of work the synth engine can sound very nice and analog, and with sampled sounds layered with the oscillators I’m getting very unique sounds. A few nights ago I was wondering if I’d bought the right synth, but after working on a patch I completely changed my mind. It just fills a gap.
Love the Analog Four. Don’t know why people complain that it doesn’t sound as good as other analog synths. I prefer the tone of the Prophet 6, but the Analog Four sounds very analog in a way that gives me something different, so I don’t find myself comparing it to anything. It can go very deep and the sum is way more than its parts. I also find it great for getting a track going without any other gear.
Overall, my 2 favourites are the Prophet 6 and Prophet 12, and I think just these 2 and a good monosynth could easily fulfill all of my synth needs.
Mind you, sometimes when I use the Analog Four, I wonder why I need any other synths at all!
