Neuro 3
Neuro 3 is the free app that opens up everything inside your Source Audio One Series pedal. Edit far past what the knobs reach, load new effects, keep your presets in the cloud and try sounds made by other players. It runs on Windows, Mac, iOS and Android.
Go deeper than the knobs
Every One Series pedal keeps things simple on top: one knob per job. Underneath there is a lot more, and Neuro 3 is how you get to it. Shape parameters the front panel doesn't reach, add EQ, change the routing, and set up MIDI and external control. Save it all as a preset.
New effects for the pedal you already own
Some One Series pedals share the same hardware, and pedals in the same family share one library of effects. In Neuro you can load any effect from your pedal's family:
- Modulation: Gemini Chorus, Mercury Flanger, Lunar Phaser and Vertigo Tremolo
- Drive: L.A. Lady Overdrive, Kingmaker Fuzz and AfterShock Bass Distortion
Your presets, on every device
Sign in to your Neuro account and your presets are stored in the cloud. Sort them into folders, and find them on any phone or computer you sign in on. You can also back up a whole pedal to a file on your computer and restore it any time, even offline.
The Neuro Community
The Neuro Community is an open, free library of more than 10,000 presets made by Source Audio players. Many recreate well-known pedals. Every preset has its own discussion thread, so you can ask the person who made it how they got there. Find one you like, try it, and send it to your pedal.
SoundCheck: hear it before you plug in
SoundCheck runs a bit-perfect emulation of any Source Audio pedal on your phone or computer. No pedal required. Pick a preset, play it through one of the built-in clips, and change the settings while you listen. It's the easiest way to try a pedal before you buy it, or to audition a preset before you send it to your board.
Connecting your pedal
Neuro 3 connects to your pedal over USB. What you need depends on where you run the app.
Computer (Windows or Mac)
Every One Series pedal connects to Neuro Desktop over USB. The connection is two-way: the app reads your pedal's settings as well as sending changes. Most pedals have a USB mini-B port; Artifakt and Pathways use USB-C. If your computer only has USB-C ports, use a USB-C to mini-B cable or a USB-A to USB-C adapter.
Android
Every One Series pedal connects to Neuro on Android over USB, and the connection is two-way: the app reads your pedal's settings as well as sending changes.
iOS
Most One Series pedals connect to Neuro on iOS over USB too. On an iPhone with a USB-C port, use a USB cable that fits your pedal. On an iPhone with a Lightning port, add Apple's Lightning to USB camera adapter.
Eight pedals are the exception on iOS: Gemini Chorus, Mercury Flanger, Lunar Phaser, Vertigo Tremolo, L.A. Lady Overdrive, Kingmaker Fuzz, AfterShock Bass Distortion and True Spring Reverb. On iOS these connect through the headphone output instead, with a Neuro Cable from your device's headphone jack to the pedal's Input 2. Any standard 1/8" to 1/4" TRS cable works the same way. This connection is one-way: the pedal takes your edits, but it can't send its settings back to the app. For two-way editing of these pedals, connect them over USB to Neuro Desktop or to Neuro on Android.
| Pedal | Computer | Android | iOS |

FAQ
Neuro isn't changing my pedal over the headphone cable. What should I check?
This applies to the eight pedals that use the headphone cable on iOS. Work through these in order:
- Make sure the 1/4" end of the cable is in the pedal's Input 2.
- Turn your device's volume up to 100% and send a change from the app. The control input LED near the top of the pedal should flash.
- If the LED doesn't flash, or it flashes but nothing changes, lower the volume to between 40% and 95% and try again.
- Unplug the cable from your device and send a change. You should hear a burst of white noise. If you don't, check the headphone output with a pair of headphones, at low volume: the noise is loud.
- Turn off any sound processing on your device, such as bass boost or 3D effects.
- If your device is in a case, check the case isn't stopping the plug from going all the way in.
- Some devices swap the left and right channels or invert the phase. In the app, go to About and turn on Invert Audio Output (advanced). Some devices need this and a lower volume.
Remember the headphone connection is one-way. The app can't read the pedal, so a menu like Hardware Options shows its default values when you reopen it. Your settings are still saved on the pedal. For two-way editing, connect over USB to Neuro Desktop or to Neuro on Android.
My iPhone has no headphone jack. Can I still use the Neuro Cable?
Yes. Connect it through Apple's Lightning to 3.5 mm Headphone Jack Adapter. Most pedals don't need the headphone cable on iOS at all: they connect over USB (see Connecting your pedal above). Any pedal can also connect to Neuro Desktop on a computer with a USB cable.
My pedal doesn't show up in Neuro Desktop, or shows up without firmware
- Unplug the USB cable and plug it back in.
- Try a different USB cable if you have one.
- If you're going through a USB hub, connect the pedal straight to the computer instead.
- Restart your computer and download a fresh copy of Neuro Desktop from Editors and Firmware.
- Still not showing? Your pedal may need a bootloader reset. Contact us and we'll walk you through it.
I've forgotten my Neuro username or password
No problem. Usernames are case-sensitive, so first try your username with a capital first letter. If that doesn't work, contact us from the email address you signed up with. A member of our team will reset your password and get back to you within 24–48 business hours. Once you're signed in, you can change your username and password in the app.
How do I open my pedal's hardware options?
Connect your pedal to Neuro with a USB cable. Once it shows up, click the wrench icon to open Hardware Options. In the Android app, the wrench is inside the gear icon.
What do I need to control my pedal over MIDI?
A MIDI controller and MIDI cables. Nemesis, Ventris, Collider, Encounter, EQ2, Artifakt and Pathways have MIDI built in. The other One Series pedals need a One Series MIDI Adapter or a Neuro Hub. Every pedal also responds to MIDI from a computer recording program (DAW) over USB, though how much you can control varies by pedal. Questions? Email [email protected].
