MIDI CONTROL
The STINGRAY can be controlled via generic MIDI messages. To access MIDI 
functionality, the pedal requires the Source Audio Soundblox HUB (sold 
separately). Please check www.sourceaudio.net for availability. The HUB 
expands your connections to further the control of multiple Soundblox 
pedals or other devices using standard MIDI ports, USB port, Expression 
Pedal input, or additional Multi-Function ports.
Using Soundblox 2 pedals with MIDI greatly extends the functionality of the 
pedals. Having MIDI I/O allows for remote automation, external controllers, 
firmware updates, and more. Using the Soundblox HUB, you can send and 
receive MIDI data to up to five Soundblox 2 pedals.
For more information on using your Soundblox 2 pedals with MIDI, and for 
MIDI mappings, please visit our website at www.sourceaudio.net.
USE WITH HOT HAND
All Soundblox pedals are compatible with our Hot Hand accessories. Hot 
Hand units consist of a ring containing an accelerometer that detects motion 
and controls effect parameters. To enable Hot Hand functionality, connect 
the Hot Hand receiver or base station to the MULTI-FUNCTION IN and select 
HH mode with the CONTROL INPUT button. The pedal will now accept input 
signals from Hot Hand. Use these signals to control standard modulation or 
the assigned parameter.
The STINGRAY can also be calibrated to change the center-point of the Hot 
Hand control range. To do this, follow the calibration procedure below. Note 
that calibration is only used for Hot Hand mode and calibration is NOT 
required before use.
