8-voice MIDI drum sample player, up to 200 of your own samples in onboard flash

Eight-voice, one-shot drum sample player, played over MIDI from any sequencer. Same board and firmware in two formats: 3U/6HP and 1U/20HP.

• 8 slots on General MIDI drum notes, 16 voices, per-slot choke
• Velocity-sensitive with four response curves, or fixed level
• Per-slot pan across two outputs, left and right
• Kits of 8 sounds, auditioned live from the encoder
• 8 user presets saved in flash
• Up to 200 samples, about 80 seconds, stored in onboard flash. No SD card
• Ships with three CC0 kits: 808-style, 909-style and Dust
• Load your own samples with a browser-based loader, nothing to install

No pitch, no envelopes, no filters: each slot plays its sample unchanged.

Inputs: MIDI in (3.5mm TRS, Type A, opto-isolated)
Outputs: OUT L, OUT R
