A port of Dexed, a FM Synthesizer. Features over 20,000 Cartridges with 32 patches each. Comes with AudioUnit AUv3 plugin for use inside AUM and other DAW apps like GarageBand. Get a camera kit and plug in a midi controller through USB, or get a 5-PIN DIN 1/in 1/out, to: USB and use the camera kit through USB MIDI Spec, NOTE: some devices handle SysEx differently and therefore we cannot promise support for SysEx, so invest in connectors and cables wisely. If you have questions involving making MIDI-USB work the best for your situation, email support. This iOS app was designed especially with small interfaces in mind. Example: an iPhone 5S or a resizable window inside AUM. If one clicks the menu eye, a feature LOCK SCROLL can be –very– important to set knobs, sliders, et cetera: if screen size is limited. LOCK PARAMs in the eye menu locks the parameters for scrolling without knocking loose the preset. In the CARTs menu double tap a cartridge to load a series of patches, the files will have a .syx extension. To use MIDI CC, in the menu eye you must first turn on MIDI CC. When MIDI CC is on it makes the tap events react like a right mouse button click. NOTE: MIDI CC, in eye menu, doesn't have to be on after CC controls are mapped. MIDI CC touch modifier will also turn off after you have successfully mapped a CC control, or when you delete the current mappings. You can turn it on again later to turn off mappings or create new CC mappings. I would suggest setting CC knobs in the bottom section of the screen – above keyboard (if visible). Currently you must save patch in DAW – for instance: GarageBand or AUM. Once we can determine unity and saving/loading between the AUv3 plugin and the StandAlone app, external save will be eventually developed. There is a pathway set to transfer .syx files through iTunes to the StandAlone app, only. Other plans include fixing pixelated images, a quick zoom to set CC mode and updating GUI to a higher degree, make sure midi CC knobs update.

If you think FM Synthesis is complicated, it’s time to think again! BLEASS Omega brings the sparkle, character and dynamic expressiveness of FM synthesis into an intuitive, hands-on instrument. Its four FM operators are edited simultaneously from a single screen, removing much of the complexity traditionally associated with FM synthesis. Eleven algorithms open up a wide sonic range, from electric pianos, deep basses and crystal-clear pads to sparkling bells and soulful leads. Beyond pure FM tones, an analogue-style waveshaper and multi-mode filter bring additional warmth, distortion, resonant sweeps and harmonic colour. All operator envelopes and controls remain immediately accessible, encouraging experimentation rather than programming by numbers, while MPE support adds another layer of expression for compatible workflows. Four built-in effects, Chorus, Tremolo, Delay and Reverb, add movement, depth and space directly within the synth. More than 200 professionally designed presets showcase Omega’s versatility and provide instant starting points for music production and sound design. BLEASS Omega can be used as a standalone app or AUv3 instrument on iPhone and iPad. It is also available for Windows and macOS.
