Read full descriptionHide full description
TowerDub is an all-in-one groovebox for building reggae riddims and mixing dub, live. Program kick, snare, hats and perc as four independent drum voices, each with its own pattern, velocity and p-locks. Layer in Bass, Chords, Lead and Pads — warm, analog-style synths built for roots and dub, playable on a scale keyboard and recordable live with real quantized overdub. Record a vocal chop or a field sample straight into the built-in Sampler. Mix it down through a proper dub desk: send delay and reverb per instrument, sweep a King Tubby–style resonant filter across any bus, throw in siren stabs, and pass your mic straight through the board. Cut instruments in and out live, capture the whole pass with one-tap dub recording, and keep multiple mix versions of the same riddim. No subscriptions — just a warm, hand-tuned instrument built for the sound of the desk.
