Well, that is an "user error". I think you can pretty much change the cell-grid layout to whatever configuration (scale, sequence) you want. It is not even close to a guitar.
The best way I have found to use guitar as a MIDI controller is to have a regular guitar equipped with multi-out guitar pickups such as CycFi "Nu 2" series. Not cheap, as you will have to buy the special cable (drill your guitar to suit the jack-socket) for it, and the special hardware unit (acts as a DI-box as well) that splits the audio signals. Then you would need at least 6 audio-inputs audio interface and 6 instances of Jam Origin MIDI Guitar plugin. Works great, but it is not cheap and the overall latency might cross the 6~7 ms line.
