Endorphin.es Plus 3

The Endorphin.es Plus 3 Desktop Expression and Sustain Controller delivers exactly what it promises: a compact, thoughtfully designed solution for integrating expression and sustain control into a DAWless or live hardware setup. The build quality is solid and confidence-inspiring—clearly built with durability and consistent performance in mind.

Functionally, the Plus 3 performs without issue. Expression signals are smooth and accurate, with no detectable lag or stepping. The sustain footswitch integration is equally reliable, working seamlessly across multiple synths and samplers. It routes easily into most setups without requiring complex configuration or additional gear.

Its desktop format makes it especially well-suited to live environments, where space and simplicity are at a premium. The form factor allows it to sit neatly alongside grooveboxes, MIDI controllers, or modular gear, giving players tactile access to expressive performance controls without disrupting workflow.

Overall, Plus 3 fulfills a very specific need with elegance and precision. It’s a niche tool executed properly—well-engineered, practical, and musically useful.

Clearly a quality product, I succombed to 'Dom's' YouTube review partly because I did not have a decent slider control to apply expression to my DAW music mockups. As a experience pianist, using a sustain pedal is second nature to me, so pushing a button to work the sustain (meaning one only has one hand to play piano) is not any use to me - despite the multitude of reasons promoted by the sales team ie. using an arpeggiator etc. I considered sending it back, but it does what I essentially wanted it for, without spending a fortune for a more comprehensive device.
