Lambda II by Riccardo Sellan

Real-time granular effect


Lambda II is a Max for Live device for real-time granular effect.The main features are:
  • 8-voice polyphony
  • Live/Freeze mode | freeze audio input to work on the frozen buffer audio portion. If it is Off, Lambda processes the audio input in real-time
  • • Sequencer mode | grain generation in sync with Ableton Live tempo
  • Pitch | individual pitch shifter for every voice
  • Delay | delay and feedback parameters for each grain
  • Filter | the whole spectrum is granulated and filtered through an 8-band-pass filter
  • MIDI input | play grains via MIDI
  • Amplitude | individual amplitude parameter for each voice
  • Spray | stereo spatialization 
COMPATIBILITY: Ableton Live 11 Suite or Ableton Live Standard with MaxforLive | Ableton Live 10 Suite or Ableton Live Standard with MaxforLive (PLEASE NOTE: Live 10 | no MIDI input)
OS COMPATIBILITY: Mac – macOS El Capitan 10.11.6 to Monterey 12 (as of 10.1.42) | Windows – Windows 8 or Windows 10
Min. Requirements: Ableton Live 10 Suite or Ableton Live 10 Standard with MaxforLive Installed

    Our Products are generally provided as Zip file downloads which in all cases will need to be extracted and saved to your hard drive prior to installation. Details on the different file type provided and what to do with them are below.

    .alp Files – These are Ableton Live Packs and will install directly into the Packs Section of the browser of Ableton Live. When you double click on them you will see a pop up window asking you to confirm that installation is ok as the files are described as “Legacy”. This is fine and you are ok to proceed, the packs are created using the format for an earlier version of Live and so remain compatible with the current version.

    .amxd files – These are individual MaxforLive Devices and can be stored anywhere on your hard drive. We’d advise creating a folder for them and then adding that folder as a location within the Places section of Lives Browser.

    Control Surface Scripts – Please refer to the individual User Guides provided with your download, an abridged version of the installation will be shown further down this page.

    ClyphX Pro – Please refer directly to the manual and installation video for this specific product.

    Novation Circuit Packs – These are provided as individual Sysex Files and as a complete bank file. All are to be installed using a version of the Circuit Editor and not via Novations Components back up utility.

    Lambda II by Riccardo Sellan

    Lambda II is a Max for Live device for real-time granular effect. It allows you to granulate the incoming audio signal in real-time or to granulate a frozen portion of it through a 8-voice polyphony. The incoming audio can be viewed through an easy sonogram.

    Lambda II can also generate grains in sync with the Ableton Live tempo working as a step sequencer. The grains can be generated via MIDI input.

    Pitch and amplitude parameters can be individually applied to each voice.

    The parameters are:


    • Freeze | freeze audio input to work on the frozen buffer audio portion. If it is Off, Lambda processes the audio input in real-time (you can store your frozen buffer within the project);
    • Step | step sequencer mode in sync with Ableton Live tempo
    • Buffer size | length in seconds of the audio portion on which Lambda works (from 1s to 60s)
    • Gain | gain of input audio signal
    • Recycle (pre or post) | recycle/overdub the dry (not granulated) or wet (granulated) audio signal on the input stream
    • Position | position to granulate with randomness
    • Reverse | reversed grains percentage
    • Filter | each voice filters the audio stream into an individually granulated band
    • Duration | grain duration (from 0.1 ms to 5 s) with randomness
    • Density | grain density in percentage with randomness
    • Envelope | general envelope function with attack and shape parameter
    • Spray | stereo spatialization
    • Dry/Wet | dry/wet ratio
    • Volume | output volume.


    • Transpose | transpose all voices (from -24 st to +24 st)
    • Tune | fine-tuning in cents
    • Detune | detune all voices
    • Glide | smooth factor for Detune parameter


    • Delay | apply a delay on each voice. If random delays are used, each generated grain will have a different delay value
    • Slide | interpolation time between one delay value and the next for each grain
    • Feedback | apply feedback on the delay network with randomness.


    • MIDI | grains can be played via MIDI input with velocity sensitivity. 

    Minimum system Requirements


    • Intel® CoreTM2 Duo processor. Intel® CoreTM i5 processor or faster recommended – 4 GB RAM (8 GB or more recommended)
    • 1280×800 display resolution
    • Core Audio compliant audio interface recommended


    •  64-bit Intel® (Intel® CoreTM i5 processor or faster recommended) or AMD multi-core processor.
    • 4 GB RAM (8 GB or more recommended)
    • 1366×768 display resolution
    • ASIO compatible audio hardware for Link support (also recommended for optimal audio performance)
    Compatibility: Ableton Live 11 Suite or Ableton Live Standard with MaxforLive | Ableton Live 10 Suite or Ableton Live Standard with MaxforLive (PLEASE NOTE: Live 10 | no MIDI input) | Ableton Live 9 Suite or Ableton Live Standard with MaxforLive (PLEASE NOTE: Live 9 | no MIDI input).
    Please if Ableton crashes or Lambda II seems to not work properly make sure to have installed the latest version of Max and selected it on Ableton preferences as described in this link https://help.ableton.com/hc/en-us/articles/209070309-Using-a-separate-Max-for-Live-installation
