This sounds great, thank you and unr

For me trying to use Free, Linear, or Analog FIR with 131k, 262k levels on render or in real-time does not appropriately compensate for plugin latency in Logic 10.7.9, on render tracks with Equilibrium using these settings are more delayed than other tracks (at 44.1kHz sample rate). Minimum phase, and no latency analog work as expected. Does this happen for anyone else?

EDIT: After some correspondence with DMG Tech support, it seems this is not related to Equilibrium itself but is a built-in limitation of DAWS like Logic and Ableton where there is a maximum delay compensation they will handle before they stop trying to compensate for it (waiting 3 seconds for the playhead to move is absurd, so this makes sense). "We believe at 262144 it is going over the maximum amount of latency that Logic can compensate for. Reducing to 65536 seems to work ok here."

As a result, No Latency Analog and Minimum Phase work fine at 262144, but the other FIR options (Free, Analog, Linear) seem to cap out at 65k impulse length before the latency gets too large for Logic (or Ableton Live) to compensate for.
@ Skap @ rici you both ran into this and mentioned this earlier in this thread, it’s the fault of the DAW, not the plugin

Apologies for multiple consecutive posts: Found a solution to Logic’s lack of ability to plugin delay compensate for Impulse Lengths above 65k, figuring this may be of use to others (@Skap @ rici ):

Add two DMG Audio TrackControls before Equilibrium both set at -1000ms Delay. Then use Equilibrium at Impulse Length 262,144 with Free/Analogue/Linear to your heart's content. In Logic you'll want to set up a loop and hit play before freezing with these settings so Logic takes the time to "re-check" the latency of the channel, and you should see it start playing about 3 seconds before it reaches the playhead. After doing this once, then it will be safe to press Freeze and it will Freeze with the timing perfectly delay compensated as expected.

Put the TrackControl's after the Equilibrium instance, and using Cmd + Shift + Click on the Delay text to toggle samples/ms and then using two instances to enter in the required delay compensation (at 44.1k sample rate and Equilibrium Impulse Length 262,144 these come out as -88200 smp and - 42872 smp).

Long-time EQuilibrium user here, and just stumbled on a situation that has led me to want to make a feature request!

Doing some cymbal EQ'ing in IIR mode (standard digital EQ setup) and I want to quickly flip through all the Digital+ Compensation levels (16,32, 64, etc.). I would love it if I could just scroll my mouse wheel over this number to quickly flip through all of them without having to click the number and choose from the dropdown menu every single time!

Digital+ Phase is not working, it supposed to fix the high frequency deformed phase like Pro-Q's natural mode, but it's not doing anything.

This isn't the same thing, but least they have scroll available when hovering over the Subtypes. Helps you try each and every type of peak to see what you like the best extremely quickly.

That being said, would happily pay money for an Equilibrium 2.0 with only UI updates.

Will Equilibrium get tube simulation one day.

I hope not!!!
