Recently bought a helix lt, and I’m trying to record both a wet and Di using Reaper. If I use the ASIO drivers, i get record both wet and dry to reaper but no audio playback through my speakers connected to my computer. The audio instead goes back into my headphones plugged into my helix. If anyone is familiar with Reaper would love some help with this! Thank you in advance!

Help with what, exactly? What you describe is the normal and recommended setup. Your Helix becomes the computer’s audio device. The ASIO protocol demands that the same device be used for audio input and output. How would you like it to work?

ASIO requires using the same ASIO device for both Input and Output.

You need to either connect your speakers to your Helix or get a separate Audio Interface and use its ASIO with the speakers connected to that AI.

Which way you go becomes a matter of physical device placement.

To get a DI track in that scenario you place a SEND Block first in the signal chain and take that to a separate Input on the AI, along with the Main Out(s) to another Input(s) for the processed signal.

Well, on a Mac you can select your Sound Input and Output under System Settings.  You can select Helix as your input, while the output can be your Headphone jack.  If this is what you are asking... you can do the same in Windows (just don't know how exactly, because I don't own a PC right now).

No, not if you use Helix and the Line 6 ASIO driver as your audio interface device. It’s a restriction of the ASIO protocol. I believe Helix on Mac uses the Mac’s native Core Audio, not ASIO.

IIRC, supposedly, this can be done using ASIO4ALL, but IME (years ago) it sounds awful, the latency is unacceptable, and you lose other features of native drivers.

Over the years I have seen many threads here about ASIO4ALL failures with Helix devices. It is a non-compliant pseudo-ASIO driver that attempts and usually fails to do things that are unsupported by the ASIO protocol, most notably trying to use different audio input and output devices. I advise against using it.
