In Edition 44 of the Very Cool Patch Challenge, you should either use VCV’s paid Host or Host FX module, and integrate with this a VST plugin or you could use the polyphonic Turing Machine from stocaudio. Of course I did both and also used all stocaudio modules. The difficulty with hosting was that I now work completely in Linux and I would have liked to integrate Windows plugins via Carla, but unfortunately Carla only caused system crashes. That’s why I used the Synthesizer Helm, which is available on all platforms to create an arp bassline. For the melody, I wanted something like a theremine. For this I have used a module, which is not yet officially available and I do not know what it will be called. So far, it is just called Wave and is by Erik Modules or something like that.
