I really can wait for a sale on Omnisphere now!
I think I have all of the synthesis types covered now, except for granular.
In addition to Dimension Pro, Rapture and Z3TA+2, I now have Iris 2, SynthMaster 2, AIR Loom, AIR Hybrid 3, AIR Vacuum Pro, AIR Structure, SampleTank 3, TimewARP 2600, Tracktion Collective, plus many of the great free synths out there ...
Iris 2 will be a very good sample based sound machine to have. For real instruments, I have SampleTank and Structure, but for cool ambient pads and atmospherics, this will be it!
Exploring the "Rhythmic" category turns up some nice moving patches, that could easily be used as pads, plus a lot of other stuff.
The closest match to this type of sound so far I have only found in Rapture, Synthmaster, and Hybrid, which are capable of using single cycle waveforms samples as oscillators. But this takes it a huge step further. Gonna be a lot of fun!
