Trying to maximise the fluency of my live set.

[Cupachinos]

Hi All

Hope all's well and good,

I'm running Ableton 12 suite, Windows 11, Push 3 controller, looking to buy a Novation Launchkey MK4,
my live set has 8 tracks, each track with 8 devices.

I'm looking to make my Launchkey mimic the track and device selection of the push and have the same 8 parameters on the endless encoders.
Using the bottom row of 8 drum pads on the Launchkey to select the track and the top row of pads to 8 select the device,
then have the same 8 instant mapping/blue hand parameters on the encoders.

Basically I'd like to have 2 independent blue hands, that can be used simultaneously and allow me to select any of the 8 devices from any of my 8 tracks on both the push and launchkey.

Don't want to be clicking round with the mouse using "lock to control surface" every 2 minutes.

Or maybe there's a totally different, better way to achieve this??
Any help or tips are very much appreciated.

Cheers!
Best wishes.
