A new and unique Arpeggiator by BLEASS & Canblaster. Use it as a MIDI FX to control any synth or as an AUv3 Instrument thanks to its built-in FM Synth! BLEASS Arpeggiator takes the inspirationally melodic power of a classic synth arpeggiator and supercharges it with modern features demanded by today’s musicians. Developed in collaboration with top French producer Canblaster, BLEASS Arpeggiator’s capabilities extend far beyond the clichéd up-and-down monophonic patterns of an old-school synth arpeggiator, with polyrhythms, polyphony, and a large collection of highly configurable arpeggio patterns built in. The focus of BLEASS Arpeggiator is creativity and experimentation. The plugin’s hands-on user interface is as intuitive and spontaneous to use as a classic subtractive synth, so varying and adapting arpeggios on-the-fly is an easy, fun and organic experience. The plugin recognises incoming performance controllers, and includes a pair of XY pads, a pair of advanced LFOs and BLEASS’ signature Motion Sequencer. These can modulate the arpeggiator’s parameters, unlocking a deep level of creativity that is simply not available from modern step-sequencer-style arpeggiators. BLEASS Arpeggiator also offers a built-in sound generator. This is a cut-down yet great-sounding FM synth that’s perfect for creating bright, sweet and punchy sounds that can work well with an arpeggio line. You can of course use BLEASS Arpeggiator with any other synth too, with each instance of the plugin creating its own MIDI source that can be routed to any instrument within your project. More information, technical specifications and tutorials available on https://www.bleass.com/arpeggiator BLEASS Arpeggiator is available as an AUv3 plugin or standalone App. BLEASS Arpeggiator is also available for Windows, and macOS.
