This has some amazing sounds, but unfortunately in my opinion sounds not similar to the prophet 5 in anyway shape or form, I own a pro one and pro 53 has a really hard time even trying to emulate that, which I would have thought would have been a pretty basic feat, but anyway I think it soudns really cool for lead and pad sounds and is seriously worth punt if you interested in something which loosely sounds like a pro 5
I will NEVER stop using Pro53. Does it sound like a vintage Prophet? Not really. Kinda sorta enough for certain signature prophet sounds like the cutting saw leads... I really like this plugin for itself though. Its not generic in sound at all when compared to most other virtual analog poly synths. It has a sound and I like that sound and use it a lot. By today's standards its a pretty low CPU hit too.
I really like the way this synthesizer sounds, it gives a nice 1980's vibe. It's a shame it's no longer supported by Native instruments and because it's no longer supported I can't really use it in new projects because it is a 32 bit plug-in. Overall, however, I recommend this plug-in (if you can still find it, that is.)
