Misa Digital Guitar Runs On Linux 125

conner_bw writes "Imagine strumming a guitar without any strings, on a touchscreen. Think the idea is too far-fetched? The Misa digital guitar claims to be exactly this. Overcoming the natural limitations of a traditional guitar, this new instrument eliminates the need to pluck strings while using the right hand to control sound. Specs: Linux kernel 2.6.31 (Gentoo); 24 frets; touchscreen; MIDI out; RJ-45 Ethernet. My favourite parts of the site are the FAQ (How do you SSH into the guitar?), and this quote from the developer: 'Because the software is open source I'm hoping people completely change the instrument and share new "firmware" with others. Different graphics, different control ideas etc. It would all be free of charge. So I'm hoping that happens as the instrument becomes more familiar.'" The developer, Michael, has not yet promised a delivery date or set a price for the instruments he is manufacturing.

        Yes and no; players adapt and the sound of the instrument changes according to limitations. Take drums, using the bounce of the stick from the batter head is part of any good players technique. Where the original electronic kits had rubber pads, modern electronic kits use mesh heads so the feel is similar to a traditional kit. While any half-decent drummer should be able to bang out a performance

        • Midi guitars are strange

          If you try to play them the way you'd play a regular guitar, it can quickly turn into a hash.

          However, the notion of using a guitar-like interface for MIDI control is not a a bad one at all. Lord knows, there are tons of different controller-types I'd like to see. Unfortunately, the box with a grid of buttons seems to be on the ascendancy again in the Monome and new Launchpad. I've been hoping for a Theremin-like MIDI controller, where I can control other parameters besides pitch a

          • Oops, sorry about the double-post, but I just noticed that there have already been theremin to midi controllers. Moog handled one for a while called the "Etherwave". It cost $5k and is no longer in production. I also found some homebrew information. Should have used google before I shot my mouf' off.

            • That should be easy, shouldn't it? Two proximity sensors and a microcontroller to translate that to midi messages. Or maybe just send raw data via serial port and let a real computer chew it.

            • You can also get a nifty touchscreen pitch-bend controller, and run it inline with another midi device, like one of these grids of buttons. Between the two you ought to be able to get the effect you want, though you may not like mashing keys or stroking a touchpad. It seems like you also ought to be able to get the same effect with a touchpad operating a virtual midi controller on your PC...

        • I've never used a guitar midi controller, but I always thought that being able to fret a chord across three octaves might prove useful compared to the one full octave I can do on a keyboard. I used to run XXX heavy strings, like .054-.014, wound B strings, &c. That would be good for midi control maybe? The pitch doesn't change much even when you bend'em way across the neck.

      • I am a "real guitar player", and I want one of these. I've been doing a lot of experiments with music lately: alternative tunings, inserting weird things between strings, building my own strange instruments, defretting an electric guitar, experimenting with touchpad as a controller, etc. This "guitar" is on my wishlist.

        • by slim ( 1652 )

          I think there are pressure sensors in the neck, which correspond to guitar notes. The touchpad probably has columns corresponding to where the strings would be. So hit the E-string part of the touchpad while holding the first fret of the E-string part of the neck, it will play an F.

          This doesn't allow you to bend notes with the fretting hand. Most guitarists will find this to be major omission.

          To choose tones in a way 'similar' to how a guitar player chooses them.

          It is true that you can already do all that on a keyboard with a touchpad. The interesting thing though is that the keys aren't placed in the same way on a guitar than they are on a keyboard so you can compose things that sound different.

          In other words, you'll be able to compose and play differently since piano tends to make you compose in a linear way, and a guitar forces you to play notes that are all over the keyboard.

          You have never played a guitar, have you? Playing an electric guitar is fundamentally different from playing an acoustic guitar.

          Probably the best analogy would be to say an electric guitar is to an acoustic guitar as an organ is to a piano. In a piano the string is plucked by a hammer, while in the organ the sound is emitted continuously by the air flowing in the tubes.

The touchscreen is used to modify pitch and distortion with multiple fingers at the same time for multiple chords.
