The Lead Generator is a Rhythm Explorer Algorithm that is incorporated into Metro. Settings for it can be found in the Rhythm Explorer Preferences Dialog, the Marker Edit Dialog, the Rhythm Explorer Window and the Manage Lead Presets Dialog.

The Lead Generator is different than other Rhythm Explorer algorithms in that it does not use currently entered notes as input, instead it uses the chord changes in markers. It is recommended to leave the variability slider at low when using the Lead Generator. When using pitch bend, the pitch bend range of the Metro Output must be set to the same as the output instrument for correct results.

The lead generator has the following features:

• 5 independent generation algorithms that can be specified by weight.
• 8 override scales that can be specified by weight with optional override at each chord change.
• 31 derivation algorithms specified via the derivation magic field.
• Sync pitches and rhythm to MIDI track or sync just rhythm to MIDI drum track.
• Motif setting can be specified at each chord change. This allows the user to repeat the generated motif at any chord change.
• Derivation range is user specified.
• Full support for pitch bend at the specified range, Support for tail bend up, tail bend down and head bend.
• Note quantizes specified by percent.
• Preset riffs with optional amalgamation extracted from user specified Artist Preset file.
• Add riffs to the Artist Preset file.
• Paste riffs from the Artist Preset file.
• Resolving Rhythms specified by percent for each generation type.
• Support for aftertouch, modulation wheel, volume, and breath controllers.
• Support for blues turnarounds, include unique scale for turnaround.
• Reduce velocities above a certain user specified note.
• Prefer 7th chords.
• Prefer chord root note.
• Predominant scales.
• Add chords notes to scale.
• Velocity range.
• Density range with optional override at each chord change.
