Compose and arrange your music in real-time. Choose instruments individually for the 4 channels. Record live or set notes with the dedicated sequencer or piano roll of each instrument.

"This is no desktop app crammed onto a touchscreen. It seems the interface has been designed around your fingertips." Peter Kirn from CDM (createdigitalmusic.com)

cool app

thanks for dev to ios. I like the bass synth. this app needs Audiobus support and background audio. also would be nice to add a flam to the drums. would be nice to be able to work with audio share too. overall a nice app that can do better. midi works well. The distortion is nice. could use a compressor.

Longest "Bait and Switch" Scheme Ever Run In App Store

Run from this app. The slim version is no longer worth the few seconds it takes to download.

I've loved this app and have been using it regularly for a very long time—previously had my review at four stars—until this afternoon, when an automatic update removed all but one of its drum kits and many of its other features.

Tapping restore does nothing to restore any of the elements I've been using without a problem for the entire time I've been using the app.

I'm not sure why the developers felt it necessary to utterly neuter, and thus eliminate the possibility of enjoying, the user experience, but for anyone in the market for an app that's a versatile groovebox, drum machine, synth, etc., and you've heard good things about this one, ignore what you've heard.

More important, though, can you really trust developers who decide without warning to take away features you've had and have been using for years in order to engage in a scheme to begin charging for them?

In my view, absolutely not.

Nice!

UPDATE - still worth 5 stars to me. Great for acidic loops. Easy export to AudioShare. Still like it!

I'm giving it 5 stars right away because I found it so intuitive and easy to get some interesting results from. Compared to other similar apps it just seemed to click for me. I bought the IAP pretty quickly after trying it out. There's plenty more to explore but I'm already sold. I think they did a good job with this so far.
