Rhino

I don't want to duplicate what has been said already, so - you can get Rhino for 50 $ now. What you get reminds me strongly of the Yamaha SY Series (77/99) with 1000+ Patches of very skilled Programmers. Just download the Demo and have a Look. I promise you'll not regret it. Complicated - yes. But more than impressing, full of Love and the perfect Place to learn FM (if you don't just want to use the 1000+ Presets). Strongly recommended.

Zebra, DUNE, MSF, Harmor, Razor and some others in my Barn - but I really couldn't resist Rhino. This is no Mainstream Toybox. Real / "Oldschool FM" and passionate Programming. Exotic Spectra. Endless Playground and Source of Inspiration.

Edit:

- VINTAGE inclusive. Rhino can load Samples and use them as Oscillators and quiet many Sample OSC are already included that are nothing but pure Vintage FM Vibe and probably Hardware Samples.

- Rhino sounds great and unique. 90s Vibe.

- The Flexibility is oustanding and the spectral Possibilities are endless.

- FM is complicated, but it's really simple to generate interesting and inspiring Results within Minutes.
