Release Notes

Separate Pattern & Sample Generation

The Generate button now supports independent control over what gets regenerated:

• • Left-click: Generate All (samples + groove + pattern)
• • Right-click (or Ctrl+click): Opens a menu with options for Generate All, Generate Patterns Only, or Generate Samples Only

Genre-Aware Dice Per Lane

The per-track dice button now generates genre-aware patterns instead of pure random noise. When a pack is selected, dice uses procedural generation rules appropriate for the genre:

• • Kick patterns respect four-on-the-floor vs syncopated styles
• • Snare always includes backbeat on beats 2 and 4
• • Hi-hats use appropriate density for the genre
• • Tom and percussion use sparse, tasteful placement

MIDI-Only Mode

A new "MIDI" toggle in the transport bar enables MIDI-only mode. When active, internal audio is bypassed while MIDI output continues normally — perfect for using Drummer-1 as a pure MIDI pattern generator driving external instruments.

Note: MIDI-only mode is not supported in Ableton Live, which does not allow VST plugins to pass MIDI through to other instruments due to its closed MIDI effect chain architecture — all other major DAWs are supported.

Ratchets & Probability

Steps now support ratchets and adjustable probability via a right-click context menu:

• • Probability: Set per-step trigger probability (100%, 75%, 50%, or 25%). Reduced probability shows a partial overlay.
• • Ratchet: Set 1x, 2x, 3x, or 4x subdivisions within a single step. Ratchet hits decrease in velocity for a natural roll effect.

Save & Load Drum Kits

The Sample Overview panel now includes Save Kit and Load Kit buttons for managing sample sets independently from patterns:

• • Save Kit: Exports all 7 track samples and their FX settings as a .drumkit file
• • Load Kit: Imports a .drumkit file, restoring all samples and FX
• • Kits saved to ~/Library/DrummerOne/Kits/ by default
• • Kit files are portable and shareable between users

Stem Export

The export panel now includes an "Export as separate stems" toggle. When enabled, each selected track is exported as an individual file (e.g., pattern_Kick.wav). Works with both MIDI and audio export formats.

Per-Step Lock

Individual steps can now be locked to prevent changes during pattern generation and randomization:

• • Shift+Click on any step to toggle its lock state
• • Locked steps show a purple border indicator
• • Locked steps are preserved during generation and per-lane dice
• • Works independently from per-track lock
