LDM Twenty - MIDI Filter Ten & Chance Ten

Overview & The Complete MIDI Toolkit

LDM TWENTY combines MIDI Filter TEN and Chance TEN into a comprehensive 22-device toolkit for MIDI manipulation in Ableton Live. One pack introduces controlled chaos through Brian Eno-inspired probability. The other creates complex routing and conditional filtering with unique ID-based architecture. Together they transform MIDI from static input into evolving, intelligent, performance-driven sequences.

Chance TEN brings probability-based composition where notes might pass through, transpose, repeat, or trigger parameters based on percentage chances you set. Every device includes manual trigger buttons for performance control. MIDI Filter TEN adds conditional routing where MIDI flows from any device to any other device anywhere in your set, filtered by pitch, velocity, patterns, or sequences. Combined, you can create generative systems where probability determines which notes play, routing directs those notes to multiple destinations, and conditional filters ensure only specific patterns trigger specific instruments.

This is the essential MIDI processing collection for Ableton Live. Create hi-hats that randomly skip beats while occasionally transposing up an octave. Route every fourth note from your main performance to a bass instrument. Trigger chord stabs only when you play specific melodic patterns. Add stutter fills that occur probabilistically. Sequence parameter sweeps triggered by note velocity ranges. All without external controllers, complex automation, or duplicate MIDI tracks.

Chance TEN: Probability-Based MIDI Effects

Inspired by Brian Eno’s BBC-documented probability scripts, Chance TEN provides 10 focused devices (plus bonus Velocity_Seq) that introduce controlled randomness into MIDI workflows. Each device handles a specific function with elegant simplicity, designed to be stacked and chained for complex probability-driven effects.

Chance_Play: Probabilistic note gating. Only a percentage of notes pass through. Preserve Downbeat mode ensures notes on bar one always play, maintaining rhythmic anchor points while the rest of the pattern breathes with uncertainty.

Chance_Transpose: Notes occasionally transpose by the amount you set. Your bassline mostly plays as written but sometimes jumps an octave. Includes manual trigger for hands-on control during performance.

Chance_Repeat: Creates stuttering note repeats with controllable delay time and velocity. Set probability for random stutters or use the trigger button for manual control. Essential for adding movement to static patterns.

Alt_Notes: Assigns alternative pitches to specific incoming notes, each with individual probability. Eight different notes can have their own alternate possibilities, creating intelligent melodic variation within your compositional boundaries.

Chance_Drillz: Glitchy stutter and beat-repeat effects with probability controls for speed, duration, and three velocity modes (level, rising, falling). Includes velocity curve for “ghost rhythms” that sit as subtle shadows in your mix.

Chance_Note: Replaces incoming notes with random alternatives based on probability weights you set for all 12 chromatic pitches. Scale and root note settings constrain randomness to musical keys. Octave randomization adds vertical range.

Chance_Parameter: MIDI-triggered parameter randomization within a set range. Every note passing through randomizes a mapped parameter. Smoothing prevents sudden jumps. Perfect for filter sweeps, reverb changes, delay feedback that stays rhythmically locked to your performance.

Chance_ParaTrigger: MIDI notes trigger envelopes that modulate mapped parameters. Note-on makes parameters rise, note-off makes them fall. Minimum velocity threshold means only notes above certain velocities trigger the effect.

Midi_Panner: Automatic panning via LFO or note-triggered alternation. Set center position, range, smoothing, and randomization. LFO mode provides sync’d movement. Note mode alternates left-right on each MIDI note.

Chance_MIDIlay: Polyphonic MIDI delay with probability control. Delay time in milliseconds or sync’d divisions. Feedback slider sets velocity drop for each successive delayed note, creating natural-sounding decaying echoes.

Velocity_Seq (Bonus): Sequence velocity values from 2 to 16 steps. Incoming notes take on the velocity of the current sequence step. Includes humanization for variation relative to set values. Instantly adds dynamics to flat MIDI.

MIDI Filter TEN: Routing and Conditional Filtering

MIDI Filter TEN provides 10 specialized routing devices (plus bonus MF Paramaster) built on a unique ID system that enables MIDI routing from any point in any effect chain to any other device anywhere in your Live set. Break out of Live’s transport limitations and create complex conditional triggering systems.

MF Skipper: Plays only the first x notes from each selected number passing through. Filter so only the first note of every four triggers an element. Reset on clip launch for loop-locked patterns.

MF NoteRange: Filters by pitch range or single note. Allow or block specific MIDI values. Use single notes as dedicated triggers for parameter changes without affecting normal MIDI flow.

MF Velocity: Filters by velocity range or single velocity value. Let only hard hits trigger certain instruments while softer playing goes elsewhere. Create velocity-based layering and dynamics routing.

MF NoRepeat: Blocks notes if the previous note had the same pitch. Perfect for live performance cleanup where repeated notes might trigger unintentionally, or for forcing melodic variation.

MF Doubler: Triggers second notes from note-off messages. Adjustable note length and velocity relative to originals. Create automatic ghost notes, delayed doubling, or call-and-response patterns.

MF Following: Allows notes through only after specific 1-3 note sequences occur. If E3-B3-G3 comes through, the next note passes. Essential for performance-based section triggers and musical cue responses.

MF Note: Visual piano roll for intuitive note filtering. Faster and clearer than Live’s Scale effect. Click notes to allow or block them. Includes parameter triggering options.

MF Phraser: Record melodic sequences of any length. Device plays through the sequence using incoming MIDI to trigger each note. Convert rhythms to melodies, create call-and-response between tracks.

MF Span: Transport-sync’d gate that opens and closes based on sequence length proportions. Change gate length in real-time for live note filtering that adapts to tempo.

MF Allpass: Routing hub that doesn’t filter anything but makes its output available as input for all other MF devices. Create central distribution points for complex multi-path MIDI architectures.

MF Paramaster (Bonus): MIDI notes trigger incremental parameter changes. Set how many notes cycle through the full parameter range. Forward loop or palindrome mode. Performance-driven parameter sequencing.

Universal Parameter Triggering: Most MF devices include parameter mapping with AD envelope shaping and range control. MIDI Thru mode bypasses note filtering while keeping parameter triggering active.

The Synergy: Combining Probability and Routing

Used together, Chance TEN and MIDI Filter TEN create generative MIDI systems impossible with either pack alone. Route MIDI from your main performance track through Chance_Play (thin out notes with probability) into MF Skipper (allow every fourth note) into MF Phraser on a bass track (trigger recorded sequence). The bass plays every fourth note that randomly passes probability, triggering a melodic sequence. Meanwhile, route the same source through Chance_Transpose (occasional octave jumps) into MF Following (wait for specific pattern) on a chord track. Chords only trigger when the transposed melody hits a certain sequence.

Chain probability devices for layered randomness. Follow Chance_Play with Chance_Drillz. Notes that make it through probability gating sometimes stutter. Add Chance_Parameter mapping a filter cutoff. Surviving notes that trigger stutters also sweep filters. Three layers of probability create complex evolution that never repeats exactly the same way twice.

Use MF device routing to create parallel processing paths. Place MF Allpass at your track’s start. Route to MF NoteRange (only C3) on track two, MF Velocity (only hard hits) on track three, and MF Following (wait for pattern) on track four. One MIDI source triggers three different instruments based on three different conditions simultaneously, no external routing required.

How to Use

Start with simple probability. Add Chance_Play to a drum track. Set probability to 60%. Suddenly your programmed pattern has organic variation. Enable Preserve Downbeat so the pattern stays anchored. This is immediate gratification – instant evolution from static MIDI.

Build routing complexity gradually. Place MF Allpass on your main MIDI track. Add MF Skipper on a second track with a different instrument. Set the Skipper’s input to the Allpass device’s ID. Set it to allow 1 note out of every 4. Your second instrument now plays every fourth note from your main performance automatically. Add MF Doubler after the Skipper. Now it plays every fourth note plus a ghost note.

Combine both packs for generative systems. Chain Chance_Play into Chance_Transpose into MF Following on a chord track. Notes randomly pass probability, some transpose, and only when E3-B3-G3 occurs do chords trigger. Map MF Following’s parameter trigger to reverb send. When the pattern finally occurs, chords play and reverb swells. Three layers of logic create musical moments that feel composed.

Use parameter triggering extensively. Map Chance_Parameter to filter cutoff. Map MF NoteRange to delay feedback. Map Chance_ParaTrigger to reverb wet/dry. Your performance now modulates multiple parameters based on different MIDI conditions simultaneously, creating evolving timbral landscapes tied to your playing.
