I have an event with multiple instruments, with various trigger conditions. I don’t want more than one instrument playing at any given time in the event. If the event is playing when I change parameter, I don’t want a new instrument to trigger, if another instrument is already playing. Is this possible?

Probably by checking “hold value during playback” on your 2 parameters. (my first answer was completely off, I thought it was a timeline…)
