I have no idea why call “compressor up” to an Expander.
Expanders have been around since the analog days for over half a century.
If after compressing or expanding, you equalize a band up or down, it’s still
just equalizing a compressed band, or equalizing an expanded band,
instead of compressor up, or, probably soon, expander down.
I read it, but I did not understand what you wanted to say with it, since the thread was about compressors, not EQs.It just seemed to me that you were saying „compressor up“ is just a different name for an expander.
