Explore Tension Lover →Start with the connection, not the name
A model name is only the beginning of a useful comparison. If you want standalone operation, look at the controls and the available patterns. If you want computer control, identify the interface, software and operating-system requirements before choosing a box. A wireless feature is useful only when the software you intend to use can actually talk to it.
Audio adds another decision. A line input accepts an external signal, while a microphone responds to sound. Neither feature means that every device processes the same track in the same way. Our comparison table separates these questions so you can narrow the field before reading each device guide.
A guide with a declared commercial connection
STIM-SYSTEM publishes this website and sells some of the products discussed. The linked shop is separate from this guide; check the offer there for availability, accessories, delivery terms and the exact build. We describe published features and make no claim to have measured the devices under identical laboratory conditions.
The guide also separates original devices from later projects. The ET312B-to-ZC95 history explains the technical connections without presenting several manufacturers and community projects as one official product series. That distinction helps when researching manuals, support and compatible accessories.
