AutoSlide - MPE Generator

AutoSlide adds MIDI Polyphonic Expression (MPE) ramps for incoming MIDI notes.  Quickly edit the slide shape, direction and scale in the graph, and then use the Mod Matrix to enable deeper variation in your slides.  The Chance control lets you choose how often a slide is generated, and the Merge control lets you use the slide to block, add, or subtract from incoming MPE data.  AutoSlide is fast, deep and flexible enough you'll reach for it again and again.

MPE

MPE allows different notes played to have independent MIDI CC and Pitch Bend controls.  AutoSlide makes MPE magic quickly accessible to all Live 11 users, even without pricey hardware.

Versatile

Live's three standard MPE controls: Pitch, Pressure, and Slide are easily controlled in AutoSlide.  Or you can use the MIDI CC of your choosing to work with 3rd-party plugins which handle note-per-channel control data differently.

With AutoSlide you can make subtle timbre shifts to ear-bending swarms to wild drum-synth-like envelopes, all with the possibility of deeper variation and transformation through the powerful built-in modulation matrix.

Note: The modulation source names had a couple small changes for clarity after making the above Intro video. The names in these pictures are the finalized names.

Push

Take control using an adaptive control layout for Push.

Requirements

Live 11 is required.  Max 8.2.1 is also required (included automatically in Live 11.1 and higher).

Live 11.3+ is required for the Pack (.alp) installer and Presets (.adv), as these filetypes are not backwards compatible.

Not all Max for Live Devices or 3rd party plugIns currently support MPE, but many do. As of Live 11.3, Wavetable, Sampler, Analog, Collision, Electric, and Tension all support MPE!  Please see MPE in Live 11.

Support

AutoSlide is developed, maniacally polished and tested by a former Apple engineer. Your satisfaction is truly important to me, so if you have issues or ways to improve anything I release, please reach out!

Version History

In version 1.1, open the menu revealed by hovering on the ZL icon:

In versions < 1.1, check version by hovering over the ZL icon:

• 1.1.0
  • Date: 2025-08-19
  • UI: Removed the "Rate" control.  Ramps now automatically use adaptive rate output for greater accuracy with steep/fast attacks and more efficiency over time.
  • UI: Removed "Vcs" (Voices Count) setting. 15 MPE voices are now always available.
  • Beats-based durations now track tempo changes during ramps.
  • Mod Matrix:
    • Range/effect is now displayed in the graph on mouse hover (rather than only when the settings are changing).
    • Time modulation amount is now overlayed on Time dial on mouse hover.
    • Now uses Ableton Sans font.
  • Mod Matrix custom mini dials:
    • Now reflect source/row color and show inactive color when they are exclusively mapped (e.g. by Macro or live.remote~).
    • Now shows colored takeover dots for macro assignments and parameter modulation (Live 12).
    • Now display both base and modulated values (Live 12) when applicable.
    • Now work with keyboard input to set their values.
  • Release Velocity is now correctly passed through the device.
  • Expanded the Push interface pages.
  • UI: ZL logo now opens as a menu with links for bug reporting and reviews.
  • Background efficiency improvements reduce work when the device is not visible.
  • UI: Workaround initial device background color issue caused by Max 8.6 and higher.
  • All UI now appears inactive when the device is inactive.
  • UI: Removed the "hidden" toggle button inside the monitor.  The monitors are now always on.
  • Live 12 conformance:
    • "Pitch" is now "Note PB"
    • Misc. UI tweaks to better match the Live 12 device style.
• 1.0.2
  • Date: 2023-02-03
  • Now bundled as a Pack (.alp) file with a Demo set and 30 presets for AutoSlide, Wavetable and some Racks.
  • Initial values are now calculated and sent prior to Note-On.  This makes cleaner attacks, especially when used in Add/Sub Merge mode and inside MIDI Effect Racks.
  • When Add/Sub Merge was used with CC controls other than Slide, if there was no incoming data we weren't resetting the offset to 0.
  • Prevent hanging notes if notes are held and user changes Vcs count during playback.
• 1.0.1
  • Date: 2023-01-24
  • Fixed issue with playback of S-style curves after re-opening a Live set or loading a .adv preset.
  • Automation-state dots appear as expected over Mod Matrix dials, Curve, and Direction buttons (critical supporting file was missing from the initial release).
  • Fix a console error about matrix configuration on load of the device.
  • Set minimum_max_version flag to 8.2.1 due to Live theme / color compatibility.
• 1.0.0
  • Date: 2023-01-16
