You mean another non-Hydra ASM?
Nothing solid on 3.0, it just always seems to come up from conversations as something really big. I think they may make the Quantum 16 voices if you don't use the analog filter... they'll put the digital Quantum filter in, instead. That's one of the things I've heard, but it's mostly a bunch of chatter.
As to triggering it, well, it's just incorporated into my setup. I have an MPC Live as the brain, which sends out to the Wavestate, Virus, Moog Sub 37 and the TR8S, and now the Iridium.
You've probably read that the one big complaint everyone seems to have is the squandered potential of the 16 pads not being velocity/aftertouch sensitive. I agree, but I'll also say that what's nice about them is just being able to go grab the synth and sit on the couch or lie in bed and do sound design and not have to worry about a keyboard. I can also see using them to perhaps just play some chord progressions, which would free up my mental space for other playing.
