the easy way around that is to get a small mixer like a Mackie 802 or 1202 and use that to manage inputs to your DT.

A more challenging approach would be to hack together a Raspberry Pi into a USB host. There are tutorials out there explaining how to do that with MIDI, but my experience with Linux audio has largely been disastrous due to lack of patience. :sweat_smile:

The iPhone/iPad Camera Connection Kit turns the iOS device into a USB host, which is why you are able to make audio connections over USB between the iOS device and Elektron device. An MPC or a 1010 box can also be a host, but neither of those make very good portable recorders.
