Hi Riche
So i presume the "Multi Mute" I have set up on a pattern will only use the mute status the pattern is set to when pattern set was saved.
I was sorta hoping I could use the Multi Mute switch the pattern has to as a way of building arrangement witout having to save each track mute settings to a pattern - which is what i do when using the Pattern Sets live - this would allow less patterns to be saved as each pattern has 2 mute settings when using the MultiMute button...
You can use the multi-mute for that.
But you must know that the multi-mite setup is stored per pattern.
Assuming you have a few patterns with multi-mute setup in your set.
If you want to have variations of that pattern in different slots of the set, then you must copy the pattern to these slots first.
Then you can change the multi-mute state or config per pattern slot, which will not affect the others.
I suppose I must just save each part of arrangement to its own pattern - and not use the multi mute for song arangement really

Generally yes. But this doesn't mean that you cannot use the multi-mute to speed things up or to make things easier for your preferred workflow.
A song arrangement in GSS is a chain of different patterns. The difference between these patterns is your choice. Can be mutes, different sequences, tempo, instruments, or whatever.
But the song player doesn't do more than running the pattern chain.
