Hi there,
thank you for your post. For Android you have to record your samples locally on your device.
We are sorry but it is not possible to transfer samples of your computer to your Android device.
For iOS devices you can connect them to your Mac and
select application in the “Apps” section of iTunes
go to file sharing
Simply drag and drop your samples into the “djay 2 documents” window
Now you can select the transferred samples by editing the sample buttons right in the application.
I hope this helps to explain things!
Keep it up,
Lukas E.
