Recording With The Focusrite Scarlett 2i2 and Helix Effects

Regular readers will remember the problems I, and everyone else with a Katana, had with recording and playback through the thing. I gave up in the end.

I’ve been trying recording on the iPhone / iPad, using the Lexis Audio Editor, which is intuitively easier to use than the iOS Garageband. For my simple mind, anyway. Record with the mic, playback via the Apple dongle and the Katana Aux In. It kinda worked, but not inspiringly.

Then I got the Helix HX Effects. I’ve been playing with it exploring its functionality for a while. I had registered that it treated the SEND and RECEIVE ports as blocks that could be put in the signal chain. I had got as far as using a RECEIVE port / block to receive music from the phone and pass it on to the Katana.

That works because the Helix software lets us create two logical paths (A and B) between the device inputs and outputs. It’s actually easier to see-and-do on the control software than it is to explain (which is how it should be). Put all the guitar-related effects on one path, and use the other path to take the play-along music. Join the paths together at the end, so the play-along music is unaffected by the guitar effects. Works nicely.

One afternoon, I started thinking about recording again. I don’t want to use headphones, and I want to hear the sound of the guitar from the amp. That was always a problem in the past, because I was getting the guitar effects from the amp. Ever since I got the HX Effects, the amp has been set to the Clean channel and all the effects turned off. EQ’s at mid-day. It’s almost tonally transparent.

The following question now makes sense. Can I use a SEND port on the HX Effects to send a copy of the signal to an interface? The interface connects to the laptop via USB and a recording program can use the USB as an input. Also, can I take the audio out from the laptop and plug that in to the Aux In of the Katana. The HX Effects is connected to the Katana via the L/Mono output socket as usual.

I have one signal path from the guitar to HX Effects to the amp; a separate path from the HX Effects to the laptop to the recording software; and another from the recording playback to the amp. So there’s no feedback loop.

And even better… there’s no way background noise can get into the signal chain because there are no microphones!

I’m using Audacity. It’s recording software with some extras, rather than a full-featured DAW, so it will do nicely for my simple mind. I made sure it could record one track while playing back another, which is kinda key to the whole thing. I can.

All I need to be able to do is send one copy of the signal to the L/Mono output, and another copy to a SEND socket. Which is kinda the reverse of bringing in a signal from the RECEIVE port.

I tested everything I could without actually getting the interface. Everything worked the way I needed it to.

Pull the trigger. The interface of choice for the amateur is the Focusrite Scarlett 2i2, which has two inputs: either instrument jack plug or mic three-pin. (Mics need a lot more signal boost than guitars.) I need one short guitar cable (male-to-male jack plugs) to connect the HX Effects SEND to the Scarlett instrument in.

Arrives within 24 hours thanks to Amazon Prime. Took about fifteen minutes to set up, including an online firmware update. Another five minutes to set the recording volume for the guitar.

Now I have to deal with the well-known phenomenon of “recording klutz”, where hitherto fluent playing suddenly misses the beat, because someone turned the red light on. Also with the fact that my playing is, well, not quite metronomic.

Which is why we record ourselves. It’s one thing to know you’re a bit clunky while playing, but another to hear it in playback. It’s so much more embarrassing in playback.
