Nested Vector Oscillator by The Human Comparator in Stockholm, Sweeden.
The core features 4 analog oscillator (sine, square, saw) each routed to a joystick which connects pitch on the x axis and FM modulation on the y axis. This technique is known as vector synthesis, however, the developer uses it differently than ususal. Instead of offering oscillator morphing (from a to b…), he offers these functions inside the pitch and FM.
The exciting thing is certainly the four joysticks with which you can make very crazy vector experiments. As already mentioned, you can play with the pitch for each oscillator on the x axis (left to right). On the Y you can make FM on two different oscillators. For example, on oscillator A, you can make FM with OSC B if you turn up the joystick, down with oscillator C. And that goes on with the other oscillators.
You can also feed oscillator FM twice, with which very bizzare sounds are possible (OSC A -> OSC C , OSC D -> C) for example. The joystick enables the user to actively intervene in a patch and play creatively with it. The module also includes a global keyboard input that can be selected for each oscillator.
This is a 4U Buchla format module. Not a eurorack module.
