Don’t wanna sound like everyone else? BLEASS is just the right instrument for you: it unleashes your inner musical creativity by bringing music production and performance to its very core: play, perform, compose beats and melodies in a new yet intuitive way thanks to its multitrack sequencer, synthesizer and drum machine.

BLEASS is the first iOS music instrument invented for both iPhones & iPads to bring instant musical bliss with almost limitless possibilities: its powerful realtime audio engine has been designed to let you go deep in the shaping of electronic sounds without being limited by factory presets.

Record, import and edit your own samples and make sick beats out of the 16 steps sequencer with customizable filters and grooves.
Customize endlessly your mono synths by tweaking the filters, envelopes and LFOs !

Record/Edit/Start/Stop/Copy/Paste your patterns as you feel like, build and arrange your songs on the fly, apply reverb or delay effects, and let the music live!
Thanks to its unique slider controls and long-press ergonomics and its unique wild sound, BLEASS almost feels like an electric guitar.

BLEASS supports Ableton Link, Audiobus and Inter-App Audio and also works in complete synergy with all of your studio soft- and hardware gear using MIDI IN/OUT and SYNC features.

All musicians will enjoy using BLEASS for its intuitiveness and musical potential, making music composition and live performance feel completely uninhibited.

Ratings and Reviews

Eriptron ,

Are you fed up with standardized presets?

Update: The tutorial won’t help a cumbersome, and in my opinion, a poorly designed UI. Typical desktop design. Check out Outta Bass’s UI as an example of a quick, easy to use UI (and a great sounding synth), with everything on one screen. It’s AND it’s FUN to use. You spend all your time navigating in your UI. Kills creativity and hinders live play. The drums lack any real punch and the synths sound weak and toy like. I will give one star back for developer responding though.

Ok, yes, price is down but I won’t support developers trying to change the purchasing model to a subscription service. That’s ‘renting’ software. Imagivision (that’s close, if not spelled correctly. They used a silver colored box) tried that a long time ago but people were smart enough not to go for it. I wonder if the current generations are that smart? Magazines, newspapers, etc., where you get “completely” new content every month is different (and ethical). What you’re trying to do, in my opinion isn’t.

That aside, your user interface is a nightmare to use. A typical desktop/mouse pointer design mentality. You want a smart iOS designed UI, check out Outta Bass! Your UI is so poor, I didn’t waste my time trying to figure it out.
No, but I am by developers who don’t know what landscape mode is.

And this a “subscription” app! Ha! Deleted.

Developer Response ,

Only a few weeks after the initial release, we've brought landscape mode, ping pong delay, a new sample pack, a second LFO, pitch bars...
Also please notice that a single app purchase (FULL UNLOCK) is now available as well.
Finally, we encourage you to go through the tutorial in order to better undestand the UI. Tutorial videos are available as well.

Groovebox with Control

You can get the beat going and tweak parameters to adjust the sounds at a very deep level with the app. The controls are well laid out and can be adjusted at various levels to deepen your beat making pleasure. Even on an iPhone, the app is very usable and the ability to send out MIDI on the tracks allows for additional work flows.

The sequencer is well thought out and there are a number of tutorial videos which make getting started a straight forward process.
