Sequencing a Bassline on the Ableton Push

This process uses the Push's Melodic Sequencer to input notes on a timeline while keeping them perfectly in a musical key.



Step 1: Set Up the Track and Instrument

  1. Select a New MIDI Track: Create a new MIDI track or select the one intended for the bass.

  2. Browse for a Bass Sound: Press the Browse button on the Push. Use the top rotary encoders (dials) to navigate to Instruments and select a suitable Bass synth sound (e.g., a "Sub Bass" or "House Bass"). Press the Load button.

  3. Enter Melodic Mode: Press the Note button. The pads will change into the keyboard-style layout, ready for melodic playing.

Step 2: Set the Musical Scale (No Wrong Notes!)

  1. Open Scales Menu: Press the Scales button (usually located near the top left of the pads).

  2. Choose Key and Type:

    • Use the first rotary encoder to select a Root Note (e.g., C).

    • Use the second encoder to select a Scale Type (e.g., Minor, Major, or Phrygian). A common choice for electronic music is Minor.

  3. Choose Layout: Use the encoders to select the In Key layout.

    • Concept: Only the pads that belong to the selected key (C Minor, in this example) will be lit up. All other notes are hidden, ensuring your bassline sounds harmonious with the drums you already created.

Step 3: Switch to Step Sequencing View

  1. Engage the Sequencer: Press the Clip button (or Step) on the Push.

  2. Observe the Pads: The 64 pads now serve a dual purpose in the melodic sequencer:

    • The Left Column: This usually controls the pitch/octave of the steps you are placing.

    • The Right 7 Columns (56 Pads): This is the Step Sequencer timeline. Each column represents a step in time (e.g., 1/16th note).

Step 4: Sequence the Bassline Pattern

  1. Select the Pitch (Octave): Tap one of the pads in the far left column (the pitch/octave column). Try selecting a low-pitched pad for a deep bass sound.

  2. Place the Steps: Tap the pads in the right 7 columns to place the bass notes on the timeline. You can visually see the note name on the Push's screen.

    • For a simple, driving bassline, try placing a note on the 1st, 3rd, 5th, and 7th steps.

    • Then, move to a different pitch in the left column (e.g., one step higher) and place a note on the 9th, 11th, 13th, and 15th steps.

  3. Listen and Edit: The new bassline will play along with your drum pattern.

    • Change Pitch: To change the pitch of an already placed step, tap and hold the step pad, and then tap a different pitch pad in the far left column.

    • Delete a Step: Tap the step pad again to delete it.

Step 5: Adjust Note Length and Velocity

  1. Adjust Note Length (Duration): For a "staccato" (short) or "legato" (long) feel:

    • Hold the pad of the step you want to edit.

    • Use the bottom-row rotary encoders (dials) to adjust the Length (Duration) parameter. Short lengths give a bouncy feel; long lengths sustain the note.

  2. Adjust Velocity (Dynamics):

    • Hold the pad of the step you want to edit.

    • Use the rotary encoders to adjust the Velocity (how loud/hard the note is played). This can help emphasize the first beat of the loop.

6. Exit Sequencing

  • To go back to playing the instrument manually, press the Note button again.

  • The newly sequenced bassline clip is now looping in the Session View, perfectly in time with your drums.
