Xynthesizr is a streamlined yet capable 32-step matrix sequencer/monotimbral synthesizer with generative features and MIDI.

"This really is a lot of fun and, hooked up to a synth like Thor or Z3TA+, there are plenty of creative options to be explored here." - John Walden,

"Xynthesizr is about the only tone matrix app that can keep up with my short attention span. There are so many ways to shape, and constantly reshape, your sound... There's a lot to play with here!" - Tim Webb,

"Overall, Xynthesizr is a very interesting instrument that is fun to play and lovely to look at." - Tom Flint, Sound on Sound

"Xynthesizr holds a lot of creative potential, and between a user friendly interface, a practical onboard synth, inspiring generative features, and solid MIDI implementation, this is a useful tool that can really benefit a wide range of iOS musicians." - Chip Boaz,

" of my absolute go-to apps" - Sean Garland,

Super sequencer pas cher et complet. Acheter les yeux fermer.
MAJ 1.4 : maintenant on peut changer la tonalité, ou changer les notes tout en restant dans la gamme avec un clavier midi. Ajout aussi d'un CC learn. Cette application devient de plus en plus monstrueux!!!
MAJ 1.5 : Apres plus d'un an voila la maj que j'attendais. L'apport de Ableton Link de plus l'intégration AB 3 midi et audio. Petit Bémol j'aurais aimé pouvoir choisir la canal midi dans midi in de AB 3 pour pouvoir faire jouer des mélodies différentes à plusieurs synths.

5/5 appli très inspirante

Appli simple aux possibilités infinie. Les effets sont top et il s'agit d'un vrais synthé avec un vrais moteur de synthèse basé sur des formes d'ondes, non pas sur des échantillons foireux comme 98% des applis smartphone ! 2 lfo :-) de quoi vraiment s'amuser !!! Félicitations au développeur !

Des boucles géniales, modifications interactives, de la musique digne des boîtes de nuit. Séquenceur idéal en complément d'un synthé.
