how to get arranger-like setup going?

Greetings guys. I am trying to do something since long time , and no luck what so ever :(.

The idea is this:

I have an Yamaha EX5, Yamaha AN1X, Kawai K5000w, Alesis SR16, etc.

What sequencer would help me, to sing with these 4 instruments, Live, in an autoacompaniament style ?

I mean, to compose little sequences on each if these synths, and then, when I sing Live, hese synths follow my chords automatly, like an huge arranger ?:)

Let us say a situation:

I want to sing live with sequences from An1x, strings and bass and keys from EX5, and drums from Alesis SR16...Wich sequencer allows me to sing live in an autoacompaniament style ?

Please note, I do not want a sequencer for linear music, in on key, or to just transpose, i reallly need a sequncer who knows to do realtime chord recognition, from Yamaha EX5 master keyboard.


i hope you get the idea of my concern

Many thanks

respect
