I can't get it to work

I would give this app a higher rating if I could figure out how to use it. I bought this app to use as a plugin for LumaFusion. I have tried to use it like I use any of the builtin audio plugins. I get no audio and adjusting any of the controls does nothing. If I disable this plugin I hear my audio. This might be a newbie issue but if I can't get it to work I can't rate it 5 stars. I really would love to give it 5 stars because I need this type of plugin. Any advice, help. I am running app/plugin in LumaFusion 5.2 on my M2 iPad Pro running iPadOS26.

Simply marvelous

This app does a great job. Don’t go to far with it but find your sweet spot and it’s a go. Great work

I LOVE THIS APP

This is the best of all apps I run with Logic Pro

Read below, I know you’re busy

Fred, is the one of the most respected. Developer amongst the iOS community!

If anyone is having trouble using his apps, I’m so sorry to be truthful and blatant, get the wisdom for sound design and audio production first, then go for these unparalleled app’s developed by this mighty developer!

Does not self-load as GarageBand song editor starts.

As title. Generally Fred’s apps are really good. But, in Late August, 2022, Maxima unloaded, and then despite me swiping away GarageBand and then restarting it, there seemed to be a ‘memory’ in Maxima, that it wasn’t loading. Never had that before with an Audio Unit. In other words, having found which audio unit it was that unloaded, after GB’s dialogue box appeared (unload/disable?), I virtual-powered-off and back on Maxima, and in that session of GB in the song editor, it appeared to recommence working, BUT…

I copied the - now working - song as part of my workflow, then load it up in GB song editor, and although no notification appeared, FAC Maxima was not loaded. It’s unfortunately silently happening thereafter. Only happened since iOS/iPadOS 15.6 or the latest one with important security fixes, but I cannot say definitively this is the cause, it’s the only thing I personally changed about my ipad is all.

iPad Pro 12.9” M1 is the one I have, 1.4Gb free SSD. I cannot use Maxima until it’s fixed. Comprehensively looked into contacting the developer. I am not on Twitter.

The upshot is, I would have to remember to switch off Maxima and switch it back on every time I load a song in GB editor, with it in a track that’s in use. And, this cannot be done while the track is running, because that does not do the ‘fix’. I didn’t notice until after the Mastering process for me, where the drums seemed dead, and I traced it back to the effect not loading at startup. It’s just easier to use something else, or a different method to spruce up the drums, until Maxima is fixed.

Take care all.
