The Source Audio Neuro Hub is a small MIDI hub that brings full MIDI functionality to all of Source Audio's One Series and Soundblox 2 pedals. It connects up to five of those pedals through its Multi-Function ports, stores up to 128 multi-pedal "Scenes" that are recalled via MIDI Program Changes, and adds standard 5-pin MIDI IN and OUT/THRU jacks to a board built around Source Audio pedals1. The unit was formerly sold as the Soundblox Hub, a name change noted in press releases from Premier Guitar and Guitar Interactive Magazine23.
What it does for a player
The Hub's job is to turn a collection of individual Source Audio pedals into one MIDI-controllable system. Source Audio describes it as bringing "full MIDI functionality" to One Series and Soundblox 2 pedals, and its headline feature is Scene saving: up to 128 multi-pedal Scenes, each recalled by a MIDI Program Change, so a single message can set several pedals at once1. Reviewers have made the same point. Pedal of the Day's review of the Vertigo tremolo advised players who wanted deeper control to "get yourself a Neuro Hub for incredible MIDI control, allowing for you to save up to 128 presets"4.
The Hub also appears in Source Audio's own product ecosystem as the route to deeper control of specific pedals. In the press release for the True Spring Reverb, Source Audio described the Neuro Hub as the accessory enabling "full MIDI control with the addition of the Neuro Hub"3.
Connections and compatibility
The Hub's rear panel carries five Multi-Function outputs, each a 4-conductor 3.5mm plug, for connecting One Series and Soundblox 2 pedals. Alongside them are a standard 5-pin MIDI IN and an OUT/THRU jack, a passive expression pedal input, and a Hot Hand Sensor Input1.
| Connection | Detail |
|---|---|
| Multi-Function outputs | 5, on 4-conductor 3.5mm plugs, for One Series and Soundblox 2 pedals1 |
| MIDI | Standard 5-pin MIDI IN and OUT/THRU1 |
| Expression pedal input | Passive "TRS" input, stereo 1/4 in. plug, tip hot, 10k-50k Ohm resistance, linear type1 |
| Hot Hand | Dedicated Hot Hand Sensor Input1 |
Compatibility reaches back as well as forward: the Hub is compatible with the original Soundblox 1 and Soundblox Pro pedals, but without Scene Saving on those units1.
Scene Saving works with One Series and Soundblox 2 pedals. With older Soundblox 1 and Soundblox Pro pedals the Hub is compatible but does not save Scenes1.
Power and setup
The Hub runs on 9 volts DC at 40mA, rising to as much as 80mA when Hot Hand accessories are in use. It takes a 2.1mm inner diameter, 5.5mm outer diameter barrel plug, center negative with barrel positive1. The unit measures 3.8 in. wide by 2.1 in. long by 1.4 in. high and weighs 6 oz.1.
For MIDI setup, Disaster Area Designs' support documentation for the Hub says to "Configure using Hub Manager to set Hub MIDI channel"5, so the Hub's MIDI channel is set through the Hub Manager software rather than on the unit itself.
Price and naming
Source Audio lists the Neuro Hub at a sale price of $99.00 USD as of 2026-10-251. The unit was originally the Soundblox Hub: Premier Guitar's 2015 press release referred to "the Neuro Hub (formerly the Soundblox Hub)"6, and Guitar Interactive Magazine's Jonathan Graham used the same framing in a 2016 press release2.

Questions
How many pedals can the Neuro Hub connect?
The Neuro Hub connects up to five One Series or Soundblox 2 pedals through its Multi-Function ports, which use a 4-conductor 3.5mm plug. It is also compatible with the original Soundblox 1 and Soundblox Pro pedals, though without Scene Saving on those units.
How many Scenes can the Neuro Hub store?
The Neuro Hub can save and recall up to 128 multi-pedal Scenes, each recalled through a MIDI Program Change. A Scene sets multiple connected pedals at once, so one Program Change can reconfigure a whole board of Source Audio pedals.
Can I connect an expression pedal to the Neuro Hub?
Yes. The Neuro Hub has a passive expression pedal input, taking a stereo 1/4-inch plug, tip hot, with a resistance of 10k to 50k Ohms and a linear taper. It also has a dedicated Hot Hand Sensor Input.
What power supply does the Neuro Hub need?
The Neuro Hub runs on 9 volts DC at 40mA, rising to as much as 80mA when Hot Hand accessories are connected. It needs a 2.1mm inner, 5.5mm outer barrel plug, center negative with barrel positive, so plan your supply's spare capacity accordingly.
How do I set the MIDI channel on the Neuro Hub?
According to Disaster Area Designs' support documentation, you configure the Neuro Hub using the Hub Manager software to set the Hub's MIDI channel. The Hub itself offers standard 5-pin MIDI IN and OUT/THRU jacks.
