I'm another user that has everything IKM including much of the iPhone hardware and software. Not really anywhere left to go. Early on I got in on a whole bunch of group buys and all of a sudden I owned everything! Not just the synths but bunches and bunches of the add on sound packs.
Then the iPhone explosion and I got in on that too.
The biggest innovation I've seen at IKM is that in its 2 main current programs Amp 3 and Tracks CS there's a slick method of selling more mini modules like amp and cab and processor emulations at grossly inflated prices. I'm afraid I don't see the value in it anymore
Still there's been a lot of long winded talk of ST 3 so I'll see what's on offer when it happens.
