TC HELICON GO TWIN Audio/MIDI Interface

Q: is this compatable with Iphone 13?

Yep I have a 13 pro max works pretty great 🤓

Q: I need usb-c for an s10 phone. do i have to get an otg adapter or is there a cable i can buy? disappointed it wasn't included!

If you read my review on GoTwin I have described what I know on compatibility issues. Have only tested my Android pad with included usb micro to usb A otg cable adapter. Don’t use Android usb-c devices so can’t tell you any more. But as a tip I can say you have probably best chance to use the S-10 with a powered usb-c hub. And connect Twin to the hub with included cable. But usb hub has to be specified according to Usb 3.0 and be usb audio class compliant. My iPad connects with such hub via highspeed usb-c cable, without any otg adapter between. But can’t guarantee this. You have to test yourself. Cheers
