The line 6 pod studio has two instrument inputs and two line inputs. Could I use the Line inputs?
No. It doesn't work that way.
Google MIDI. Digital (midi) guitar is a different thing. It uses 6 sources, it's hexaphonic. Multi-transducer pickups
Hexaphonic pickups (also called divided pickups and polyphonic pickups) have a separate output for each string (Hexaphonic assumes six strings, as on a guitar). This allows for separate processing and amplification for each string. It also allows a converter to sense the pitch coming from individual string signals for producing note commands, typically according to the MIDI (musical instrument digital interface) protocol. A hexaphonic pickup and a converter are usually components of a guitar/synthesizer.
Such pickups are uncommon (compared to normal ones), and only a few notable models exist. Hexaphonic pickups can be either magnetic or piezoelectric.
Hexaphonic Pickup (ie. Roland GK3 or Transducers in the bridge of Godin LGX SA guitar) goes through a 13 pin cable (Roland set the standard that everyone uses) to an Interface Box (Roland GI20, GR series, VG-99, Axon etc.) this converts to MIDI which feeds a Sound Source (midi sound module) or the equivalent in software program in a Computer (DAW etc.). Through a midi interface or USB.
Monophonic mode ie. each string feeds it's own sound module or you could set it to polyphonic where all six strings play one sound module. Practically you wouldn't do that though because a pitch bend of one string would be pitch bending all the other strings since they share the same sound module in Poly Mode.
MIDI (Musical Instrumental Digital Interface is kind of the modern equivalent of a player piano scroll. Since it's inception it's kind of become ubiquitous. It's used all the time to control things, you have it in all kinds of programs now where you don't know it's being used. It's a control language. Lighting rigs, even machinery can be controlled by it. More current versions are bypassing it's original speed limitations by basically being interpreted in faster protocols.
When you get to a unit like the Roland VG 99 it has the midi digital part but they also have taken the use of the Hexaphonic pickup to control software emulations of sound. Called virtualization. COSM Componenet Object Software Modeling) is there trademark name for it. Basically you could think of it as imitating things more like an effects pedal while MIDI is like a scroll playing on a player piano.
