I’m trying to add a multiband EQ effect to a single snapshot and not the entire mixer – but adding it to the snapshot appears to set it for everything. Is this possible?
No it isn’t, the effect will be present whether the snapshot is activated or not. But the snapshot could automate its behavior, which probably is what you want. The simplest way is probably to automate the frequency of the multiband EQ with the snapshot (from max by default to the value you want).
Thanks @Alcibiade, I had tried that but couldn’t find neutral settings. Going and trying what you propose seems to work as intended, and gets the job done for my needs.
