I’m learning the Tocante Karper, one of the latest in the line of Tocantes by Peter Blasser. Here’s a demo video in which I show some of the playing technique I’ve discovered. I don’t know the theory of its design. This is an empirical investigation. (I had it plugged into my Roland Mobile Cube amp.)
- Pitches start out similar to the other Tocantes when powered on. But, each pad/oscillator can be changed to a random pitch, widely ranged.
- New pitches are held until power cycled or changed again.
- The random pitches are obtained by the inner two pads. I don’t yet understand how the two pads work in relation to each other.
- Quickly striking the large pad produces a plucked sound that is strongly pitched.
- Holding the large pad produces a sound that seems to me like a guitar string stimulator, a centered pitch with a lot of activity.
- I didn’t demo the inner nodes. As far as I can tell they inject noise.
