CPS

I've been using CPS when I want to sketch weird signal chains or build generative rigs that respond in real time. Instead of menus and presets, you work on a canvas: drop processing and control modules, link them together and tweak parameters while audio flows. It runs as a VST2 so you can drop it into a DAW on Windows or macOS and start building immediately.

Why it shines:

• Visual, modular workflow — assemble synths, effects and controllers by connecting modules with virtual cables.
• Handles audio, MIDI and flexible I/O, so you can route microphones, controllers and host signals into your patches.
• Great for sound design, algorithmic composition, live performance setups and teaching synthesis fundamentals.
• Low-latency operation suitable for on-the-fly editing during rehearsals or studio sessions.

If you like experimenting beyond fixed presets and want a sandbox for DSP ideas or performance patches, CPS is a compact, hands-on way to prototype and perform unique sounds.
