Chromatic Sequencer


The Chromatic Sequencer is a Max for Live midi effect that creates a random sequence quantized to pitch and rhythm. It’s a stochastic sequencer which means it randomly chooses what to play. But, you determine the pitch and rhythm.


The Chromatic Sequencer is a Max for Live Midi Sequencer that controls three basic parameters: pitch, rhythm and randomness.


You can quickly quantize the sequencer by selecting the notes along the top ribbon. Only want it to choose the notes of a C major chord? Easy. Just select C, E and G. Want it to choose from the notes of a particular scale? No problem. Just turn on the notes you want to hear.

The Octave setting allows you to choose the range of the notes it chooses from. For example, if you select notes C and G and set the Octave to “4”, it will choose from C4 and G4.

If you want to expand the range of notes to choose from, use the +/- setting. Setting +/- to “1” adds an additional octave above and below the Octave range selected. For example, turn on note C, set Octave to “4” and +/- to “1”. The sequencer will chose from C3, C4 and C5 randomly.

If you want a certain pitch to have a stronger/softer accent or longer/shorter note length, use the Velocity and Note Length settings below each note.

Select the rhythmic subdivision using the ribbon on the far left. If you want it to randomly play eight notes, select 1/8. It’ll randomly play eighth notes in time with the Ableton project.

Subdivision Rhythm
1 Whole note
1/2 Half note
1/4 Quarter note
1/8 Eighth note
1/16 Sixteenth note

Use the probability knob to control how often it randomly chooses a note. For example, setting the subdivision to 1/4 and probability to 100% means it’ll play on every quarter note. Setting to 50% means it’ll play half of the quarter notes. The chart below shows how the device might choose when to play based on the probability setting.

There is a built in LFO that can modulate the velocity and note length of each note as well. LFO Freq controls the rate of the modulation while LFO Amt controls the amplitude. As an example, setting the Velocity of a note to 64 (about half way) and the LFO Amt to 40 means the velocity will modulate between 64+/-40 at the rate of the LFO.
