Hello,

Here is a very little part of a bigger amxd. The simple purpose is that when some tracks are soloed, other defined tracks are soloed too.

I don"t understand why this patch is only working when in edit mode... If I close edit mode, nothing is working anymore without any error in the console.

Just open a new live.set and create 20 empty midi tracks In the first one, create a Max Midi Effect and copy the patch below.

Any help will be very appreciated !

Merci !

Julien

EDIT. solved with some deferlow before live.object...
