A new and unique Arpeggiator by BLEASS. Use as a MIDI FX or as an AUv3 Instrument thanks to the built-in FM Synth!
Available for Win. / Mac / iOS

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 (huge fun on iPad!), a pair of advanced LFOs and BLEASS’ signature Motion Sequencer. These can modulate the arpeggiator’s parameters, unlocking a deep level of creativity that’s 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 the kinds of bright, sweet and punchy sounds that can work so 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 bussed to any instrument within your project.

I’ve been trying to find an app like this for months. Love it.

Interesting wish it would adapt to GarageBand better

OK so I got it to work in GarageBand sort of but when I use something called cadence with I forget what setting it was when I hit record it changes what it sounds like which is very uncool, but other than that I’m pleased as I run at the mouth… Blah blah blah, and I have yet 2 figured out how to get midi instruments to play instead of the built-in…………

Continues Without Input

Works well for a while, then wigs out and continues playing whether there’s input to it or not. Very nice while it’s working. Really could use a manual to explain some of its cryptic controls.

Will gladly revise this review if/when problems are resolved.
