Need advices about preset management

[La Tenaille]

Hi,
I use the grid as a play list to change tune (a tune per grid line). The grid is triggering a master preset manager with a fader (the master pm is in a "util" rack and set to workspace).
Now I'd need, for each tune, to store various FX states in 8 different racks, and recall them with 2 controller buttons per rack (increment/decrement).

I really don't see how to achieve this simply. Let's say I've 15 tunes and 5 FX presets per tune, that make 75 presets per rack...

Thanks for your help

ok so i suppose you have try first the Usine playlist but you don't like it ?

The trouble with playlist is it needs a workspace per tune. Updating all the workspaces each time I change a single thing in a patch doesn't seem a solution to me, but perhaps I miss something ?
