In principle recently to create music I use Ipad 2. Synths and sounds I take from the application Animoog, Samplr and Garage Band. Drums DM1. And of course to connect it all i use Audiobus. By way of DAW i use Auria app. And also i have got alesis dock station to connect guitar or violin and vocal if needed. Finished product (Of course, if you can call it a finished product because the quality of the recording wishes to remain to be the best)) I am mixing in Tractor DJ app.
This is all.
