Recording desktop synths directly to the iPhone 15

Last week my iPhone 15 landed on my doormat, well the guy did knock and pass it over to me and I've been trying it out as a camera over the past few days. I've got some great photos of the kids for example but I shall share some other photos on my blog soon, as I haven't really been away anywhere with the new device.

This morning I thought to myself that it would be worth trying to record a desktop synth via a direct USB-C connection, which you can now do since Apple have dropped their proprietary lightning lead. Would I be able to do it using the stock camera app?

Low and behold, yes to all of the above. It works best where you can monitor the sound via a headphone connection, which with the Roland S-1 you see here, you can.

I've questions though - Will it work with a dongle, that is connected to a number of hardware instruments or an audio interface for example?

I want to record these little jam sessions to share here and probably elsewhere on the socials.

Thanks for reading, watching and listening!
