It offers up to sixteen audio input/output channels (eight stereo/sixteen mono) that you can use for processing or performing. Using sequencer modules, you can generate MIDI for other DAW tracks via sixteen MIDI input/output channels.
There are over 170 official modules and over 2000 on the VCV Library; you can automate up to 1024 parameters and run multiple instances in your project. In terms of the number of creative options, it’s a monster.
