A clean, functional interface that focuses on workflow rather than flashy graphics.

At its core, Cthulhu is two tools in one: a and a Pattern-Based Arpeggiator . It doesn't generate sound on its own; instead, it acts as a MIDI "brain" that sits between your keyboard and your favorite synthesizer (like Serum, Massive, or Sylenth1). 1. The Chord Engine
