Creating an old-school music tracker-style sequencer in Max for Live (M4L) is a fun and creative project! Trackers are known for their vertical, pattern-based interface where notes are entered in a grid, often with columns representing different instruments or voices. Below is a step-by-step guide to building a basic tracker-style sequencer in Max for Live:


1. Plan the Interface

Before diving into Max, sketch out the key components of your tracker:

  • Pattern Grid: A vertical grid where each row represents a step and each column represents a voice or instrument.
  • Note Input: A way to input notes (e.g., via MIDI or a virtual keyboard).
  • Playback Controls: Play, stop, and tempo controls.
  • Pattern Length: Adjustable pattern length (e.g., 16 steps, 32 steps).
  • Instrument Selection: A way to assign different instruments or samples to each column.

2. Set Up the Max for Live Device

  1. Open Ableton Live and create a new Max for Live device.
  2. Drag and drop a Max Audio Effect or Max MIDI Effect onto a track, depending on whether you want to trigger samples or MIDI notes.

3. Build the Pattern Grid

The pattern grid is the core of the tracker. Use a multislider object to create the grid.

Steps:

  1. Add a multislider object to your patch.
  2. Set the multislider to display a grid (e.g., 4 columns for 4 voices and 16 rows for 16 steps).
  3. Use the multislider to store note values (e.g., MIDI note numbers).

Example:

  • Use the multislider's output to send note data to a coll (collection) object for storage.
  • Map the multislider to a live.grid for a more polished Ableton-style interface.

4. Handle Note Input

To input notes into the grid:

  1. Add a notein object to capture MIDI input.
  2. Map the MIDI note numbers to the multislider grid.
  3. Use a message box to set the active step (e.g., set 1 60 to set step 1 to MIDI note 60).

5. Create Playback Logic

The sequencer needs to step through the grid and trigger notes.

Steps:

  1. Add a metro object to control the tempo.
  2. Use a counter object to step through the rows of the grid.
  3. For each step, retrieve the note values from the coll or multislider and send them to a noteout object.

Example:

  • Use a counter to iterate through steps (e.g., 0 to 15 for a 16-step pattern).
  • Use tabread or coll to read the note values for the current step.
  • Send the notes to noteout for playback.

6. Add Instrument/Sample Support

To assign different instruments or samples to each column:

  1. Use a umenu or live.menu to select instruments.
  2. Route the note data to different channels or sample players based on the selected instrument.

Example:

  • Use poly~ or sfplay~ to trigger samples for each column.
  • Use midiout to send notes to different MIDI channels for external instruments.

7. Add Playback Controls

Add buttons and sliders for:

  • Play/Stop: Use a toggle to start/stop the metro.
  • Tempo Control: Use a live.dial to adjust the metro interval.
  • Pattern Length: Use a number box to set the maximum step count for the counter.

8. Polish the Interface

  • Use live.grid, live.text, and live.button to create a clean, Ableton-style interface.
  • Group elements into subpatches (pattrstorage) for better organization.
  • Add visual feedback (e.g., highlight the current step in the grid).

9. Save and Test

  1. Save your Max for Live device.
  2. Test it in Ableton Live by loading it onto a track and triggering notes or samples.

Example Patch Structure

Here’s a simplified structure for your patch:

[metro] -> [counter] -> [multislider] -> [coll] -> [noteout]
[notein] -> [multislider]
[toggle] -> [metro]
[live.dial] -> [metro interval]

Advanced Features

Once you have the basics working, you can add more features to make it feel like a true tracker:

  • Pattern Chaining: Allow multiple patterns to be chained together.
  • Effects: Add per-step effects like volume, panning, or pitch modulation.
  • Sample Offset: Allow samples to start playback at different points.
  • Save/Load Patterns: Use pattrstorage to save and load patterns.
