Connections
Rear
The rear panel of the Hub features MIDI I/O, an Expression Input, and a Sensor Input for use
with Hot Hand.
• Sensor Input: Connect a wireless Hot Hand receiver or wired Hot Hand unit here. The Hot
Hand unit will be powered from the Hub. The Hot Hand signals will automatically be routed
in either digital or analog mode to any connected Soundblox pedals.
• MIDI IN and OUT: Standard 5-pin DIN connectors can be used here to connect a MIDI
controller to the MIDI IN jack. The Hub can receive and respond to a variety of MIDI
commands. See the MIDI Features section for more detail. The MIDI OUT jack is by default
a MIDI Thru connection. This means that any messages received on the MIDI IN port are
immediately passed to the OUT port. The function of the MIDI OUT port can be changed
using the Hub Manager application.
• Expression IN: Connect a passive expression pedal (example: SA161 Source Audio Dual
Expression) here using a stereo (TRS) ¼ in. cable. If using a 3
must be "tip hot" and the value of the internal pot should be in the 10k to 50k range for
best results.

Top Panel Controls

The Hub v1 has a very simple interface on the top panel. The blue POWER LED should be lit
whenever the device is powered. There are also two buttons that perform multiple functions:
• Scan Devices (Hold – Save Scene):
• Scan Devices: Pressing the Scan button will send a "ping" message to all of the
attached Soundblox devices to check the connections and the state of the pedal. The
Hub automatically scans the attached pedals when it power up. However, if a new
pedal is connected later, press Scan to make sure that the Hub is properly connected
to it. The MIDI LED on any connected Soundblox 2 pedals will blink to acknowledge.
• Save Scene: Pressing and holding the button for two seconds will perform a "Scene
Save" function. The Hub queries all of the attached Soundblox pedals settings and
stores them in flash memory inside the Hub. There are 128 Scene locations. By
default, scenes are stored to location 1. To access the other locations, connect an
external MIDI controller. The Hub will automatically save scenes to the last received
MIDI Program Change number (1 through 128).
