You certainly couldn’t accuse Teenage Engineering of not providing long-term support for its OP-1 synthesizer - we’re now up to firmware update number 243. As with all previous updates, this is a free one, and it adds some potentially useful functionality.
Specifically, the OP-1 is now capable of streaming over USB. Or, to put it another way, it can now function as a USB audio interface.
So, not only can you sample and record to the OP-1 directly from any USB audio host, but you can also send audio from the OP-1 into your PC or Mac DAW.
There are a couple of other tweaks, too - external tempo sync stability has been improved and when tape is armed and OP-1 receives a play command, recording now starts.
The firmware update is compatible with all versions of the OP-1, and you can download it from the Teenage Engineering (opens in new tab) website.
