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.
