Firmware Update - Rob O'Reilly Expressiv MIDI GUITAR SYSTEM Getting Started

Firmware Update

What is Firmware?
Firmware is the software that makes an electronic device operate in the way it does.
Why would you need to update it?
If there are improvements, extra functionality or other features available, why not have them. By updating the firmware
with the most recent software development, this allows you to avail of these features and improvements.
Basic Steps to update the firmware
1) Get the most recent software update from RORguitars.
2) Download the program needed to send the new software to Expressiv. Right now, that is the Arduino IDE programming
software which is available to download from www.arduino.cc
3) You need to switch an internal programming switch on the guitar. Remove the backing plate of your Infinity Guitar to
access the electronics and you will see a small sliding switch on the green printed circuit board. Switch this in the
opposite direction
4) Plug the guitar into your laptop or desktop computer (mac or PC) using a standard USB cable
5) Upload the software which takes about 30 seconds.
6) Switch the internal programming switch back to the initial position and replace the back cover of your guitar
7) It should now be working as normal but with the new firmware installed.
Single Channel - Multi Channel Mode
What is Multi-Channel Mode?
Multi channel MIDI mode on Expressiv allows you get different sounds from each string. This gives you huge sound
possibilities with some software programs and also gives you 132 individual MIDI outputs from your string/fret contacts. The
default setting of Expressiv when powered up is multi-channel mode.
What is Single-Channel Mode?
Single Channel mode means Expressiv only sends on channel 1. This means you can only control the same sounds from all
your strings. However, when using hardware synthesisers, this may be much more convenient because it requires no
complicated setups. If you plug into a synthesizer and you do not sounds from some of the strings, just flick into single-
channel mode and you can play
How to Change from Multi-Channel to Single-Channel Mode:
To change from Multi Channel to Single Channel mode
1/ press and hold the octave down button
2/ now at the same time, pull the spring toggle switch towards you.
3/ You will see the infinity mirror flash. It is now in single channel mode and you will get channel 1 from all strings.
Note: when you power down Expressiv it will be re-set to multi-channel mode.
