I released a pack of 16 scripts that netplements the current library.

Chord - Smarter version of the current Chorder. About 100 presets.

Chord Bank - Build a bank of chords.

Mono - Force mono playing.

Mono Group - Force mono playing for selected notes. (Ex : hihats choking)

Bass Extractor - Only plays the lowest note (convenient to add a sub)

Random Note - Add randomness on note parameters. The "static" mode applies a fixed random number (eg a detuned instrument), while the "dynamic" mode renetputes the random number each time (eg a bad musician)

Random Play - A random arpeggiator. Useful for creating FX, ambient noise. Can be associated with the script "Random Note".

Scale - Restricts all MIDI notes to a defined scale.

Transpose - MIDI Transpose.

Note Range - Limit the range. Notes out of range can be muted, played at the nearest octave or more.

Note Single - Redirect all notes to a single one.

Piano Analyzer - Midi note analyzer.

Fix Overlaps - Maintains consistency between "note on" and "note off". This script ensures that two notes with the same pitch will never overlap.

Mapper - Map the desired control: Velocity, midi cc, etc ... Can be used to limit the velocity, making it soft, hard, or constant, reverse a midi cc.

Delay - A simple delay in ms.

Double - Play octave.

All these scripts are loaded into a rack of type "Event", "+" button and "Script Processor" submenu.

The pack is available on my website for free :
