Possible disadvantages

    VCV Rack can be demanding on system resources, requiring a powerful computer to run smoothly, especially when using numerous or complex modules.

    As a standalone application, it requires additional steps to route audio and MIDI to/from a digital audio workstation (DAW), potentially complicating the workflow.
