I have the same concern. My collaborators are not DAW literate are on both PC’s and MAc’s and do not have an iPad. I find the plugin to be confusing to use for this purpose. Like VST Transit Go for the Ipad, I would like to see a stand alone application for PC’s and Mac’s
I can report that I’ve tried vsthost (free) and it almost works. The Join editor screen appears,and I can log in and upload the project. However, I can’t use the transport buttons on the plugin screen to make it playback or record. If I enable the processing engine on vsthost from the toolbar, the join plugin returns to zero and begins to play the tracks. If this could be solved , it would be a great solution. However, It looks like there is not much development for this host going on.
I tried the demo version of Blue Cat Patchwork ($99 US) and it crashes immediately on plugin load.
