The NDLR sits between your keyboard controller/sequencer and your synths, and can control up to eight MIDI synthesizers.
The NDLR is currently being developed via a Kickstarter project.
Here’s what they have to say about the video:
This is a quick demo video of the Conductive Labs NDLR during my beta testing of their pre-production unit.
The NDLR is a “Sequenced Arpeggiator” device that can be used with both software and hardware synths; shown here being used with 4 instances of U-HE Dark Zebra soft synth running in Ableton Live. (I added a drum track afterward for flavor.)
