These are surely the epitomy of " FAT BASTARDS ", and each have their purposes and unique character.
I will load up Adern Flexor III and Modular also, and pray that the polyphony restraints will not interfere w/ my high poly demands. I need at least 6 voices on my synths since I use 5 voice chords, and always play the root. The 7th and 8th voices are needed so the envelopes won't re-trigger. However on certain presets that is a desirable feature as the entire sound gets re triggered, and this sounds awesome w/ a reverse delay, or reverse reverb effect.

I will also have Celmos BlueWave w/ 16 voice polyphony for those fine ass FM Pianos. I'm sure that Celmo didn't plan on this synth being an electric piano, but it's presets of FM EPno's are stunning through a Scope mixer, and beat the pants off of any sampled EP, or FM8's sounds.
QWave and Multi-Synth can be layered since they are 4 part multi timbral, and I will use them as a giant 8 part synth, or 4 part emulation of a Waldorf Wave w/ many more tricks up it's sleeves.
Solaris 5.0 has no equal in analog emulation since JB added the new performance features to it. It is the FATTEST BASTARD I ever had and sounds like a giant Modular Moog doing 8 voice pads. I never owned one but heard Keith Emerson using his live back in 1972, and I thought it sounded so FAT, that the Gods from Olympus had descended upon us. I was only 16 years old then and drove my dirt bike 40 miles to see that show, but it made an impression on me that I shall never forget. Solaris 5.0 has filled that void with great sucess.
To Us, And Those Like Us.
