Their architecture must be far more flexible than Ableton, who's 9 -> 10 upgrade was seriously underwhelming for the five years they had to work on it. Nested groups, multi-track editing, and capture are all welcome, so I'm not discounting what they DID add, but for the life of me I can't understand why here is still: No MPE, no VST3, no inline VST MIDI effects (you still have to use multi-track hacks), no comping, no global time signature changes, and the same stunted MIDI/Audio routing system.
The Grid has Max4Live directly in its crosshairs. It is obviously not a direct replacement — yet, but it covers 90% of the way most people use Max, without the need to dive into the guts of Max signal processing, and with far superior DAW integration.
My prediction is that this is a prelude to Bitwig releasing a module designer app, with full access to the DSP components that underly the existing built-in synths and modulation system, that will bring this thing home.
