I just happened upon this video:
It's a selection of Amiga music produced using a program I've never heard of before: "Symphonie Pro".
Does anybody know anything about this program? Most particularly, the sound it produces seems vastly in excess of anything I've ever heard from an Amiga. It sounds less like a sample-based system, and more like an actual subtractive synthesizer, with convolutional reverb, distortion effects, phasing, etc. And the video description talks about how this program is "aimed at high-end Amigas" and uses "software DSP".
Thing is, real-time subtractive synthesis should be vastly out of reach for any Amiga. Certainly programs like OctaMED could do realtime wavetable stuff. But I've run both FM synthesis and subtractive synthesis programs on the Amiga, and none of them were even remotely real-time. (E.g., multiple minutes to render a 6-second synthesizer riff. And it sounded awful anyway.) So I'm confused as to how this program works. Does anybody know anything about it?
