Latest VEP7, intel i9 Mac latest

Repro:

1) Launch VEP7 and create a new instance

2) Add channels for any two 3rd party AU plugins (VST plugins and Synchron Player do NOT suffer from this bug): could be Kontakt AU, SINE player AU, Spitfire Originals AU... your pick

3) The bottom channel should be selected, just press the left arrow key which should select the next higher channel...but.....

=> Immediate crash out of VEP7, Mac desktop is all you see

I thought I saw a bug fix announced of something like this at some point recently, but if so, it has regressed.

(Also, I posted a lot of feedback (much of it positive) in this forum on Synchron Prime Edition and it all got deleted. Fear not criticism. The "Johann Strauss rather than Richard Strauss" line I'm not letting go of, that was bullseye. But I do like your stuff anyway.)

Another thing. Seems that MIDI controller assignments don't survive my typical power cycling of instances, at least when on disk. Annoying to have to re-learn them all the time.

(I'm not actually certain what the repro steps are here. But these are steps I do, and it keeps failing. I would explore what exactly breaks it; it's something along these lines.)

1) Create a new instance, with an instrument plugin of your choice, and add a VST or AU FX plugin to the channel.

2) Create a new MIDI controller over there on the right of the screen, learn the controller assignment, and learn the plugin parameter to use for it.

3) Power off the instance, and save the server project.

4) Quit VEP, relaunch it and open the saved server project, open the instance and power it on.

=> MIDI controller will still have its source assignment but not its target asssignment into the FX plugin which will be blank and won't work.

I power the instances on only when I need them, as I have > 150 instances, one per instrument, as makes sense for Logic.

Seems left-arrow got fixed in the last update.

Make 200 instances using the vertical orientation option and drag them around. You won't miss it...it's just an off-by-one bug on the size of the list element. You are thinking you're dropping between instances 3500 pixels from the origin but it's actually 3900 pixels (or thereabouts). Your list elements are actually one bigger than you're adding up, at least on Mac. This is a common enough bug to have in a dnd list, someone has to sit there and make 200 instances and test it and own their error. Don't overindulge them.

I repro'd the MIDI controllers bug here

Although I'm still not 100% certain that will always break them. But I always break them somehow. The screen just looks like blank in the right column where the parameter would be, but the controller in the left column is still listed. I am not doing any other operations to the plugins or MIDI controllers, they are just breaking.

Most likely this is a conditional serialization bug: on Save As you are doing a tree search for data to save vs data not to save (probably because you are mixing in all sorts of ugly backpointers and GUI pointers in the model layer, given the quality of this implementation that would be about the programmer level). And when the power on the instance is off you are bailing on that leaf of the tree prematurely; that's still data you want serialized of course. As your programmer masters the craft they will learn not to do things this way, just like the Import bug kludge.
