Source Audio SA 250 / Ultrawave Multiband Processor

The Source Audio One Series Ultrawave Multiband Processor embarks on a pioneering journey into the advanced potential of overdrive and tremolo, exploring a brave new universe of sounds yet unheard. At the Ultrawave's core is a dynamic and multi-dimensional approach known as multiband processing. This process splits the frequency spectrum of a guitar, bass, or synthesizer into multiple, discrete frequency bands and equips each band with its own array of adjustable parameters. In the case of overdrive, the Ultrawave splits the incoming signal and provides separate drive and output level controls for each individual band.

The result is a thick and rich distortion with loads of unique overtones and dynamic interplay. Split the signal into 1, 2, 3, 4, 8, or 10 frequency bands, and apply any of the band splitting options to an exciting collection of overdrive types, including Tube, Diode, Foldback (a method of distortion often heard in the world of synthesizers), Octave Up, Negative Flip Diode, and more. The Ultrawave also has an incredible companion collection of innovative sound processing blocks to take sound creation into vast new directions. These are found in the Neuro Desktop Editor (free editing software for Mac or Windows) or Neuro Mobile App (free for iOS and Android). All presets created in the Neuro editors can be loaded directly to the pedal, saved to a personal, cloud-based preset library, and published to the Neuro Community to be easily accessed by other Ultrawave owners. The dual channel compressor block includes studio level controls that can be placed before or after the drive circuits. The Multiband Tremolo block provides individual control of each band's tremolo depth, rate, and start time as well as its LFO wave shape. Changing the LFO wave shape and varying the tremolo start times of each frequency band creates fantastically propulsive sounds reminiscent of sequencer or arpeggiator effects. The LFO’s Ring Mod option creates waves of retro/futuristic industrialism. The Morph feature explores the marvelous potential of sound morphing, which allows musicians to smoothly transition from one supercharged tone to another with an external expression pedal, LFO, or envelope follower. The Ultrawave also has advanced stereo features that can send entirely different drive effects to each of the outputs for a wide stereo field, place the effect in two places in a signal chain, or generate mind-spinning, ping-pong tremolo effects. Plug in, turn up, and explore the wonders of multiband processing built on over a decade of refinement and experimentation.
