The DG-20 can function as a MIDI controller which will allow you to control other MIDI modules, synths, tone generators and even software based synths: It operates in Poly mode allowing you to control your MIDI synth polyphonically on a single MIDI channel (MIDI mode 3). Importantly for guitar players needing individual control on each string, it also operates in Mono mode which allows you to assign a different sound/part to each string which is transmitted on individual MIDI channels for multi-timbral/multi-part control of your MIDI synths making the DG-20 a powerful and dynamic controller. (MIDI mode 4) The instrument selector buttons on the DG-20 send program change signals to your MIDI synth allowing you to change patches and performances on your MIDI synth remotely from the DG-20. The Start/Stop button which controls the rhythm section playback can also be used to trigger a MIDI sequencer or drum machine.It has adjustable tempo, transpose and tuning with separate guitar and rhythm volume controls .
It also has a built in speaker plus a headphone socket and an audio output jack for connecting to an amp or external speaker.
It powers off an AC adapter or batteries
It’s very easy to use, a manual is hardly needed but a copy of the manual is included anyway in pdf format
