My keyboard is a VPC1 (no internal sounds - strictly a MIDI controller). Although I can play along with pre-created tracks in BIAB (using other VSTi software), I'd love to be able to have a virtual band follow me rather than me follow it.

I've found software that follows my chord changes, but nothing that senses, then follows my tempo changes.

Basically, I'm looking for either a software or hardware solution that will allow me to choose a style and have it follow my chord and tempo changes without me having to fiddle with a computer keyboard or touchscreen in the middle of a live performance.

I know that this is asking a lot, but does something like this exist?

Any recommendations appreciated!

Kawai VPC1 MIDI Controller; Asus A53E Laptop running Windows 7 - 64 bit; BIAB 2017 UltraPlusPak (upgraded from 2014 EverythingPak), running from Laptop's Hard Drive.
