Dylan, I "used to have" a 224, but it was too unreliable, so I sold it.
What I liked about it was the remote, with those faders, you could move them all at once and get a global decay adjustment, unlike the 91, where you have to menu dive for each frequency. What I didn’t like about it was the fan noise! I had to have it on a 10m remote extension down the end of the hall, it was like a hoover!

On the PCM90 — and I expect the 91 is the same — the low Rt decay time IS the global decay time adjustment.

It acts as a multiplier for the mid and high frequency decay times so that they track with it to maintain the correct proportions and tonal balance.

It's all explained in the PCM90's manual... so I can't believe it's not in the 91's manual too.

Well, changing the low rt certainly doesn’t sound like it's altering everything, sounds very muddy the more I increase it. I can understand if it had two functions, but what’s s the point of having a dedicated low rt if it affects everything? although changing the crossover seems to do "something"
And it's sort of annoying when you read on the preset list that the most important parameter to change on this sound is "decay" what? there is no decay parameter, or "change delay time" that doesn’t exist either, it's just very confusing listing things that aren’t mapped. This machine definitely "isn’t" intuitive.
Also, I’ve trawled though most of the presets and found a few decent things that I've edited into sounds I like, OK, I’ve got a nice dreamy space, a long epic "Running Blade" reverb, a couple of nice small percussion spaces, that’s it, job done, no need to edit anything anymore.

Update, as I know you’re all "so" interested :)
I've been through all of the 450 presets, and created about 40 sounds of my own, in fact, I've used it so much I've got used to the sound of it now.
I also know what all the cryptic parameters do, and understand the "adjust" knob and how to assign it, I’ve managed to create some lovely "playable" verbs for piano/EP, very inspiring, but where this unit really shines is in very realistic small/medium spaces, especially for percussion, it's worth having just for those.
All I need now is a Yamaha SPX990, to complete my collection of my favourite hardware verbs.

Yes, makes a change doesn’t it :D
It’s amazing how some bits of kit get their feet under the table so quickly, this Lexicon even looks happy, and it oozes quality.
