A mix of wishes and (possible) bugs here:
I'd love to have toggle buttons for going through amp models. Im just firing up an old track and with so many Fender amps available, it's hard to know what is going to work. To flip from one amp to the next, you have to click a few times and move the mouse around. Arrows would make this way faster. You wouldn't want to do this on an AxeFX where scrolling through amps can go through TOTALLY different amp types. Here they are more curated and its quite feasible that any of them could work on a given track.
I'd also love on the cab block to be able to hold a modifier to drag the mic position more granularly. It would also be good to be able to click and drag the text boxes for position as well as the actual position graphic. It's currently quite hard to accurately adjust distance without moving position. If you can drag the text boxes, it ensures you only move the intended axis.
I'd like to see a bit more exposed to the user as far as phase, timing and MPT. Blending doesn't feel particularly realistic to me. It all feels very convenient and dumbed down but at the expense of losing a more realistic workflow. To hear what I mean, try blending mics together and move the position around, both in distance and horizontally. I get why it is the way it is, but it does not feel or sound natural to me. Many sounds are simply not achievable.
It would be great to be able to lock parameters and blocks in place via right clicking. Both for auditioning presets, and also just when dialling things in.
I think there may be a with the Room feature on the cab block. When on a mono instance, blending it in sounds very comb filtery. If you do the same on a stereo track and pan both channels to mono. It would be great to have a mono option for this where it's only processing a single channel for the room mic, rather than doing L and R and summing them.
When duplicating the plugin to another instance, the "do not show this screen at startup" setting is being ignored and it's showing every time. There's also no way within the plugin to save the default window size as default (this can be done with a DAW factory setting but it would be great if this was handled by the plugin too, then it applies across DAW's and standalone).
The tuner feels janky graphically. I'd love to have the strobe mode, but also for the ballistics to be smoother. Submission Audio LockOn does a really solid job at displaying strobe style and needle type tuning in the same view.
The delays are too basic. Not just with the models available, but also with the parameters themselves. There are also too few reverb types. It needs some curveball options, not just meat and potato spring/room/hall. IMO the parameters are also too dumbed down for the reverbs.
There should be more graphics and knob styles across all the different block types. This goes for cabs and mics too.
Im on the latest Pro Tools AAX on Mac Sequoia.
