tracks record and monitor button loose they’re state after switching song:
Not tested but may be also on .30 ?
As i have ALL my songs with stacks linked to tracks, i now have to monitor enable each song each time to ear live stacks! 
Ciao!
EDIT: problem only in audio tracks types
Ciro, I cannot confirm this bug.
I created exactly the same project - two songs, two audio tracks in one song and routed to the Song. Set both buttons on and after switching songs forth and back the buttons are active as expected.
Tried with new midi update mixer actions enabled? That is the only new function I have active
Ouch, sorry. You didn’t mention remote mixer. I don’t have touchosc, but just tried to activate that option in preferences and it don’t change for me anything, button states are good.
@Spork @musicullum I confirm this happens only with midi update mixer enabled.
Sorry, Record and Monitor had been forgotten for remote MIDI, fixed with the next Version.
