Obsidian is one of MIDI Maker’s experimental palettes, built from massive spaced hits. The bass strikes the three heads of a half-time tresillo and holds; metallic chord stabs answer only on the sixteenths the slabs leave empty, over one granite sustained bed.
What to listen for: Huge bass hits spaced far apart at a slow, heavy pace, short metallic stabs answering in the gaps, and a few dark notes hanging far above.
Obsidian is included with the Pro and Studio plans; the free plan covers five genres. See pricing.
How the engine writes obsidian
The single melody is an omen: a few long tones a bar at most, huge intervals, mostly silence, drawn first from the Locrian mode. Velocities slam between full slabs and near-whispers, and some progressions phrase their chords 3+3+2 in beats so the harmony is a tresillo too. The kit is a dub pulse built for the delay: a deep kick on the tresillo’s heads, a static snap on a three-bar cycle, a pin hat, and a sub drop where a slab lands.
From a roll to your DAW
A roll defaults to 70 BPM (every preset and tempo is editable before and after generating) and plays back in the browser through the studio's own synths. When you like a take, export it as whole-track or per-instrument MIDI, or as WAV/MP3 audio — the drum part uses General MIDI numbering, so it lands correctly on any drum plugin. There are step-by-step import guides for Ableton Live, FL Studio and Logic Pro.
