Now that the baseline guitar is constructed, future work can add novel functionality and expand the expressive range of the instrument. First, pitch bending may be implemented - the accelerometer hardware and pd code is in place, just the Arduino code needs to be adjusted, and then overall pitch could be altered by tilting the guitar.
Another idea we had was a built-in sequencer. The arduino memory could be used to store a section of playing, perhaps commanded by another external button, and then that could be played on command, or looped under continued playing. Different expansions on this same idea: the Arduino could loop just the fingering or just the picking, allowing the player to concentrate on the other to produce more complex music more easily.
To expand the 'acoustic guitar' functionality, the arduino could carry multiple tuning maps onboard, to be selected by the player to automatically assign the fretboard different tuning, or a virtual capo.

I was extremely impressed by how this project turned out. The system succeeded at imitating the sound of the original device. AND, the led's were a great touch for the "star power."
ReplyDeleteWe really liked the fret sensing concept which you guys implemented on your project and we laud your efforts for that. The electronics was very well contained in your mechanical enclosure. About creating the feel of a plucked string, Prof.Gillespie had given us an example force profile, which simulates a plucked string. Not that you would use it after the course is over, but may be in future...
ReplyDeleteI think the overall design was really good and the sound produced was very nice. However, it was very difficult to play a guitar while standing without a shoulder strap, so adding that will definitely improve the playability.
ReplyDeleteI thought your guitar was beautifully made. The amplitude control with the accelerometer was very intuitive, and your "giant voltage divider" fret sensor was implemented well. Great job!

I think your guitar is beautiful and delicately made. It's good that the size is like the real guitar people used to play. So users' fingers can fit into different positions ti change the tune easily.
ReplyDeleteIndeed, your guitar showed some real craftsmanship and I was impressed at how well the voltage divider concept worked out. Wioll take a little practice to learn how to play...but nice job.
