What we say about the Instruo Seashell...
Instruo's first foray into semi-modular desktop synth territory is as smart as you'd expect from one of Eurorack's most premium brands. If you've lusted after their products but maybe didn't want to go all-in on a modular rig, the Instruo Seashell is the perfect way to get a bit of that Instruo flavour in your studio or live setup. The compact size, beautiful interface and clever software integration is what makes this really stand out from other monosynths in a crowded field.
