je le télécharge et 30 secondes après je me prend pour cut chemist! C'est très intuitif, très ergonomique, et, contrairement à beaucoup de soft de musique, c'est en quelques minutes que l'on peut sortir un petit morceau plus ou moins bancal mais assez encourageant pour continuer (pas comme sur reason par exemple!). Les possibilités son assez limitées mais suffisantes pour se prendre pour grand mixer DST sur rock it (feuw feuw fresh freuw feuw fresh feukeufeukeufresh). Le seul vrai hic, c'est que c'est un peu mécanique (yo) ça manque de feeling de soul brotha tuwoiquoi?

Scratching Without Records
Create scratches without a turntable, mixer, or vinyl records.
iScratch produces realistic scratch sounds based on standard scratch notation - it "plays" the scratch with the realism of a turntable system.
Anyone can add scratching to their music library.

Create and edit
Create basic scratches from the built-in tools: Push, Pull, Baby, Release, Chirp, Tear, Hold.
Add Fader control with the Click tool - several clicks can simulate a Crab.
Choose any sound to scratch (AIFF format). Change input sounds during the composition.
Control the duration of the input sound. The Waveform control shows exactly which portion of the input will be used to generate the scratch.
Control the pitch of the scratch. Edit the notation so that it plays over a shorter time but uses the same amount of input sample. This will produce a higher-pitched scratch.
Copy & paste notations to easily repeat parts of your scratch.
Drag notations to change their position.
Time and Measure tracks show how long your composition is. Create a few seconds or hours of scratching.
Play back the scratch composition or just the notation you are working on.
Play the input (source) sound.
Add a backbeat.

Save and share
Use the Document Info window to title your composition, set its copyright, or add notes.
When you save your iScratch™ file, all of the input samples used to create it are bundled into the file. Send it to a friend and they will see and hear exactly what you created.
Print your scratch composition like sheet music to use for performances.

Export and mix
Export your iScratch™ composition as an AIFF file. Put your composition on your web site or import it into GarageBand, Soundtrack, Logic, or your favorite music application.
