Does Matriarch have presets?

No — the Matriarch is 100% analog with no digital storage of any kind. Every parameter is controlled by a physical knob or switch, and there is no patch memory. This is a deliberate design choice that encourages attentive, present sound design, but it means recreating a favorite patch requires notes or photos of the panel layout.

Can Pro 3 be used as a MIDI controller?

Yes — the Pro 3 has MIDI DIN in/out/thru, USB MIDI, and four CV/Gate outputs for controlling modular or vintage analog gear that predates MIDI. It can sequence external hardware simultaneously while playing its own internal voices, making it a capable hub for a small hardware setup.

Is the Matriarch stereo?

Yes — the Matriarch has a full stereo signal path from oscillators to output, and its built-in stereo analog delay creates a genuinely wide, lush sound. Running it through a stereo effects chain or into a stereo interface captures the full width. This makes it unusual among semi-modular instruments at this price tier, most of which output mono.
