Today I got to try a demo of Jam Sessions, a new game for the Nintendo DS from Ubisoft. It’s due out in a month or two. It’s basically a guitar synth. The buttons are used to “finger” different chords, then you pluck a virtual string displayed on the touch screen. You can use a real guitar pick, even. The sound quality was pretty good. I have Electroplankton, and the sampled sound on that is pretty ropey.
