Making Lua scripts snapshot-friendly

[piRoN]

So in my Roland MKS-7 panel I’ve got mostly straight-up sysex modulators, but there’s a handful of MKS-7 settings that use bit-packed parameters. Right now I’ve got those switches calling a Lua script when their value changes, which just gets the values for all the relevant controls, builds the midi message and shoots it out. That works great, but it does mean that those settings aren’t being output when you do a “Send Snapshot”.

I couldn’t find any specific info on how the snapshot functionality works, so I’d like to know if there’s a “proper” way to set up these sort of scripts to make sure that they work correctly with it.

I thought i added a special callback on snapshots, but i see it’s not there (must have slipped my mind). I will add two callbacks that will be triggered right before and right after a snapshot has been sent, so you get a chance to add stuff to the snapshot if needed.

Awesome, cheers Atom.

Wow, a working MKS-7 panel !
Is there a way to find it ?

Thanks
