Still on 8.5, maybe this is already in 9?
Would be great if there was an Auto-On option for the components of a channel strip such as the EQ. For example, moving the low-pass frequency on the channel EQ would engage the filter on. This would also be very useful because if you have Quick Controls saved in a track preset where you have hardware rotary controls automatically mapped to the lowpass, highpass, etc - it’s very quick to engage and get sounds happening.
Noticed this is working on the dedicated hi/low cut filters.
