I recognize that the Muse Receptor is "special", but I feel like getting z3ta+2 is *this* close from being truly workable on that platform.
 
Two main issues (with OS1.9, which is not the latest):
 
- You cannot recall patches via the Receptor host software. You can select patches within the VST's browser, but whatever the VST needs to respond to in terms of "load this patch" from the VST host... well, it ain't happening. That's the real show-stopper.
 
- The vertical slider GUI elements don't work. Everything else seems to: rotary knobs, switches, horizontal sliders, changing FX order, menus... just the dang vertical slider! Not THAT big a deal, because if patch loading worked, you could do sound design on one machine and then load patches into your Receptor version.  But given that patch loading doesn't work...
 
Otherwise, the synth sounds and performs great on the Receptor.

Put in a problem report to Cakewalk.

I don't think this qualifies as a "problem" though? That's why I posted here, as Receptor is not an officially supported platform for the product.
 
 
I don't know enough about the VST SDK or what the Receptor host to send patch definitions to a plug-in, but I suspect the problem is some disconnect with that particular API.

These are known issues, maybe there's more to add not sure. You will probably experience the stuck note bug as a guess...

Some insight: I could not load .fxp files via the plugin's menu option. Not sure why that would be. As the Receptor appears to save plug-in state as fxp files, if there are issues with z3ta loading fxps to begin with, well, there you go. I can't imagine why this would be a problem except for some mismatch in file handling between z3ta+2 and the WINE environment the Receptor uses.
 
Given that the original z3ta runs on Receptor, along with a large number of other VST2 plug-ins, it is a head-scratcher.
