App géniale!

Comme développeur et musicien, je n’ai jamais réussi à imaginer une ergonomie acceptable pour écrire la musique à la volée sur mon iPhone. Eh bien, Flat l’a inventée!
Très facile d’utilisation, très complète (on peut écrire des choses bien complexes!), et toujours dans la poche, cette app est l’outil absolument idéal du compositeur intempestif.
Je garde une étoile pour moi cependant, car la restitution audio n’est pas terrible : le son accroche, crachotte, bref, c’est moche. Manque de ressources de mon vieil iPhone 6? Je ne pense pas. Bien que ce soit une fonctionnalité un peu secondaire, j’aimerais pour jouer ce que j’écris avec une qualité acceptable.
Au chapitre des améliorations, j’aimerais également pouvoir sélectionner les voix/instruments que j’écoute. Histoire, par exemple de comparer deux versions d’une partie instrumentale.
En tout cas, bravo aux développeurs!

Bonjour est il possible que ce logiciel retranscrive sur une partition le morceau que je joue sur mon piano . Merci pour votre réponse

Colis on ,


A peine quelques minutes pour piger le fonctionnement. J’écris mes partitions sur Notion depuis un bon moment. Vraiment top pour des partitions simples. Est ce une version limitée?? Pas trop compris....

Developer Response ,
