The legendary ARP sound, exquisitely reproduced in software. ARP ODYSSEi - A mobile analog synthesizer for iOS. The ARP Odyssey of 1972 has earned an unshakable position as a classic analog synthesizer. In 2015, KORG produced the ARP ODYSSEY, a complete reproduction of the original. The ARP genes that shook the worldwide music scene are being passed on, and its history continues. The next platform for the ARP ODYSSEY is iOS. We want the unforgettable ARP sound to be easily available on a device that as many as possible of today's players can obtain; this resulted in the "ARP ODYSSEi" app for iPad / iPhone. Based on the revived ARP ODYSSEY, we used KORG's proprietary CMT circuit modeling technology to reproduce the analog feeling and sound of the original as closely as possible. We've also given it numerous enhancements that are possible only with software, such as long-awaited polyphony and built-in effects. The real analog ARP ODYSSEY, and now the uniquely evolved ARP ODYSSEi, brings the universal fascination and inimitable sound to every device. * Due to differences in CPU speed of iPads / iPhones, iPad 3rd gen/2/iPad mini/iPhone 4s are not supported, only iPad Air/iPhone 5s or later is recommended. [ Features ] - Faithfully models the circuit of the ARP ODYSSEY: The circuitry has been reproduced using KORG's proprietary CMT (Component Modeling Technology), developed over the years starting with the KORG Legacy Collection. - New functions to create all-new ARP sounds: Added a voice assign mode that allows you to play chords, an arpeggiator that can be programmed in detail like a step sequencer, and effects that can transform the sound in diverse ways. - Get all three of the sought-after revisions: In addition to the standard design of the Rev3 with its black panel and orange silk-screening, you can optionally obtain the white-paneled Rev1 and the black-paneled gold silk-screened Rev2 designs, together with fifty new preset sounds that take advantage of the distinctive filters of those models. - Produce music together with KORG Gadget: ARP ODYSSEi can be used in conjunction with the "KORG Gadget" music production DAW app that has won numerous awards around the world. If both apps are installed, it can be used as the "Lexington" gadget inside the KORG Gadget app. More info at korg.com

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.
