Speaking on behalf of at least a dozen touring musicians, we ask you to take the parts count up a notch. Most of us use the Kronos 2 and while we understand the lack of a dedicated sequencer/ sampler, we can't get beyond the limited 8 parts at any given time. The Kronos can go upwards of 8 although limited (Somewhat) by the CPU. With all your new wonderful sounds i.e. CTX and other layered instruments, there's simply not enough latitude for most of us to jump ship yet. Yes you can say there's always the dual keyboard option, or using the FX side to thicken things up, or add instruments via elements but if one is truly looking for magical fine sounding acoustical instruments with multiple layers and splits, 8 assignable parts as you call them is not enough for those of us looking for a new performance oriented synth. And, breaking down a wonderful sounding multi layered instrument just to make room is a step in the wrong direction. I have been reading that there are others on this forum looking to do the same so my mates and I aren't the only ones looking for more parts. Your machine is a 16 multi timbral unit with good processing speeds so the hardware is up to the challange. The idea of using a Midi jumper is a bandaid approach but proves it can be done more or less. I think there would be many more of us currently on the fence regarding Montage that would jump in if this one feature could be included in a future update. 16 assignable keyboard controlled parts would seal the deal for me and others.
