The Roland GI-10 is not technically a guitar synthesizer, but rather a guitar-to-MIDI converter with no tone generation capabilities of its own. It uses a 13-pin cable to interface with a guitar pickup such as the GK-2A and has the same tracking speed as the Roland GR-1, GR-09, GR-50, and GM-70.
The GI-10 has the ability to "thin" pitch bend data and reduce the number of MIDI messages transmitted in order to prevent overloading a connected device. It also has an attack noise filter that helps with filtering out "ghost notes" caused by attack transients.
It includes a built-in tuner and has inputs for a hold switch and an expression pedal. Configuration is done via plus and minus buttons that select parameters and change their values.
There is also a microphone input for monophonic pitch-to-MIDI conversion. The quality of conversion depends heavily on the source. It doesn't do as well with vocals as it does with instruments.
