An innovative and user-friendly approach to FM Synthesis

If you think FM Synthesis is complicated, it’s time to think again!

BLEASS Omega places all of the sparkle, character, nuance and dynamic expressiveness of FM Synthesis at your fingertips, and does away with the arcane programming interfaces so often associated with FM. Harnessing BLEASS’ signature GUI technology, creating and crafting sounds in Omega is not just easier than with other FM synths, it’s easy – PERIOD!

All of the classic capabilities of FM Synthesis are available in BLEASS Omega – expressive electric pianos, deep thundering basses, crystal-clear pads, sparkling bells, and soulful leads. And thanks to the instrument’s analogue-style Waveshaper and multi-mode Filter, BLEASS Omega can inject powerful analogue-like flavour into those pure FM tones, giving searing filter sweeps, growling distortions, and harmonically-rich resonances.

The four FM operators that sit at the heart of BLEASS Omega are edited simultaneously from within a single screen, with all operator envelopes and controls available to the touch of your finger. This amazingly user-friendly approach makes light work of sound editing, and encourages experimentation and exploration in a way no other FM synth can achieve.

With eleven FM algorithms on offer, each providing a different way of interconnecting the four operators for radically different results, the sonic scope of BLEASS Omega is vast. The included library of over 200 professionally designed presets makes full use of this versatility, furnishing you with a varied and inspirational sound palette to use in your music making and sound design projects.

BLEASS Omega fits in with your workflow and studio setup, no matter how you like to create. The iOS edition provides both standalone and AUv3 versions for use on iPad and iPhone, whilst the desktop edition for Windows and macOS comes as a VST3/AU plugin instrument, compatible with all major DAWs.

Omega crashes if I try to use it with Bluetooth

Omega crashes if I try to use it with my Bluetooth headphones, when I play/hold note/s. Everything else, so far, is BLEASS at their best with BLEASS Omega❣️ ❤️🎹 Using the familiar ‘tabbed’ approach to present a wealth of control and modulation ability, all the while making FM Synthesis easily assessable. I’m glad BLEASS included their Motion Sequencer! Excellent sound quality as I listen to crisp, glistening, crystalline ice crystals faintly echoing. And that Wave Shaper can get ‘sick’ at times. Now to see what else I’ll create with BLEASS Omega. Purchased all the presets for when my Muses’ are playing somewhere else for inspiration. Some familiar names there. 🤓👍

More than your average fm synth.

I was asking myself “don’t I have enough synths? Isn’t fm kinda dull and overdone?”. But this is Bleass! They make the normally boring effects exciting and amazing, and now they’ve made FM amazing and easy.

Wish they’d improve the left/right arrows for the algorithm selection though. Too easily it brings up the algorithm menu instead of just switching between algorithms. Maybe long press for the menu instead? This is also true on my 8th gen iPad.

Otherwise this is a must, and the only fm synth you need on iOS

Fantastic for FM experimentation

Like samplewiz 2, omega is an amazing playground for FM synthesis that allows you to really create nice electronic soundscapes.The randomizer offer yields fantastic results.
