Yes, this is next generation of BIAB-like programs.

It can be used to prepare quality styles for (hardware) autoarrangers -- it has built-in rendering engine (so called "MIDI enhancer" from NTONYX, Novosibirsk, Russia).

Another programs with music rendering develops at www.musiclab.com (from Rostov-on-Don, Russia).

You can use such a programs to compose your own "quasi-live" styles more quickly than with sequencer use only.
