But, how good does it sound "unplugged"??? |

Location: Canton (Detroit), MI | Looks like an engineering senior project to me!!! Been there, done that....well, 29 years ago.....
The software to do this must have a challenge....gobs of timing loops and calibration to coordinate the neck "fingers" and the string pluckers, and to play a song at just the right rate to sound recognizable. Notice that it HAS to play first position chords...nothing "up the neck" allowed!
Notice the make and model of guitar were not even mentioned....to the engineers, it was totally irrelevant to the issue.....

Moody - anyone been studying your left hand technique lately? |

Might be kind of handy. And no backtalk. "Just shut up and play!" |

Location: Canton (Detroit), MI | I would be utterly amazed if it could do a hammer-on or a pull-off under computer control and sound acceptable. I do this type of thing (computer control systems) for a living....the amount of control to do that would be STUPENDOUS. Far more than college students would generally be capable of(time and resources limited).

Location: Tampa, FL | Hammer-on, no big deal simply a matter of timing in the sequencing list. Would depend on the design of the actuators used to finger the fret board. Pull-offs are more of a technique problem. Most players do a pseudo pluck as they pull off to keep a fair amount of string vibration going on. That might be a more difficult effect to create. Depending on the latency (the time between telling and actuator to press/release a string and the actual occurence) and the consistency of the latency, you might be able to simulate a pull off by doing a second pluck withthe string partially released. But as OAO states, most college students I've run across will not have the time or the interest to approach these problems. The average student, having achieved what you see on that web site would just collect their A and move on. It is a pretty neat implementation, nicely executed.
Just looked at the fingering section a little closer and they used spring returns on the actuators. That kind of precludes any kind of pull-off capability, other than some kind of trickery with string plucks timed to coincide with partially retracted fingers. If you look closely you'll see that the plucking mechanism is "push/pull" in that there is a solenoid to drive the actuator in both directions.
Other limitations of this system are an inability to add coloring techniqiues like bends, slides and various pick attacks. The lack of these are what will give this device its 'harpsichord' like quality. but I'm thinking it could execute some totally bizarre midi files. And could do some inhuman things since it doesn't have the finger count limitation most of us are saddled with. |

Location: Las Cruces, NM | Damn thing looks a lot like a DEC PDP-8 8K memory computer I had in the lab at General Atomics in the 1970s, it had flashing lights that signified the contents of it's 12 bit memory locations, a wire and washer memory bank, and it wasted 100 times more time than it saved. It could easily have played "chopsticks" if we had contracted with a DEC machine language programmer and it wouldn't have cost more than $8 million, and would have failed half way through the song so DEC would get another $8 million to trouble shoot it and inform us we needed a PDP 10 to do that job.
