ADD by LDM Design

Unstable length modulated sequencer


Build on the idea of instability, this MPE compatible sequencer creates constantly changing patterns of notes with modulated note parameters. Each time the sequence reaches the end, the sequence length itself grows or shrinks, within predefined limitations, creating unpredictable rhythmic patterns. The changes in length can also be mapped to velocity level, note length, and MPE slide and pressure parameter values.The device consists of 8 note sequencers with individual controls for grow mode, step size, minimum and maximum sequence length, growth amount, hold, and probability. It also includes the option to freeze specific sequences to prevent changes. Global controls allow us to set swing amount to loosen up midi timing and note pitches can be set using a scale selection.
COMPATIBILITY: Ableton Live 11 Suite or Ableton Live 11 Standard with MaxforLive Installed
Min. Requirements: Ableton Live 10 / 11 Suite or Ableton Live 10 / 11 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.

    ADD by LDM Design

    ADD Features –

    • 8 length-modulated single note sequencers 
    • Individual control of all parameters for each sequence
    • 4 grow modes, including freeze
    • Modulation of velocity, note length, slide and pressure per sequence
    • Control step size, growth rate, length hold and probability
    • Add global swing and set pitches using scale control

    Once again LDM Design has delved into the void and pulled out another unique tool for bringing instability and chaos into the generation of midi notes and parameters.

    This device was designed to introduce chaos into what is usually a stable value in a step sequencer – the length of the sequence. In a normal sequencer, we set up the desired length and then we leave it, creating usually predictable patterns of notes. Instead, the ADD device has instability at the core of its functionality, and so with 8 sequences, each changing the length of the sequence on each pass, either growing, shrinking or creating a random length, we can get some barely controlled chaotic and unpredictable midi patterns firing out the other end. 

    Still, we do have a lot of control over how the changes happen and also what parameters are affected by the constantly changing values. The minimum and maximum length of each pattern is set and depending on the growth mode, the size will grow and shrink between these limits. We have individual control of the step size, grow mode, growth amount, length hold & probability, as well as being able to set specific limitations for parameter changes. We can also hit freeze on any of the sequences to instantly stop the length changes and maintain a constant looping pattern.

    We also have an interesting and unique function which controls how the sequence can be mapped onto a new length. When we select the Stretch mode, the selected midi pattern is saved in relation to the size of the sequence at that point. Then, when the size changes, that pattern is mapped proportionally along the new length. If a note is saved at step 3 of a 4 step sequence, then using Stretch mode, this will be mapped to step 5 of an 8 step sequence length. This is similar to using the *2 or /2 buttons in Live’s midi clip editor, and can create even more interesting ways for the pattern to change as the length grows and shrinks.
