Tobinski Interpolating Scanner

Tobinski Interpolating Scanner in detail

The Tobinski Interpolating Scanner is a sophisticated module featuring 8 VCA channels routed into a combined mixer and scanner section. The eight VCAs serve as the starting point: if the CV and individual outputs remain unconnected, they act as input channels for the mixer/scanner unit. When a single control voltage is applied, it modulates the amplitude of the corresponding channel. Plugging a cable into a VCA’s individual output removes that channel from the mixer/scanner section. All channels feed in parallel to both the mixer and scanner sections, which have independently configured outputs. Odd outputs carry channels 1, 3, 5, and 7, while even outputs carry channels 2, 4, 6, and 8. A dedicated mix output (“All”) sums all signals. The mixer section controls how many adjacent channels are selected, while the scanner section can jump selectively between stages and/or crossfade between them. Both areas feature a bipolar CV input with attenuator, and the processes can be automated using tw LFOs. The Interpolating Scanner excels at dynamically distributing signals across the stereo panorama. Its inputs accept both audio and CV signals, making the module suitable for complex modulation tasks as well. It can be expanded with the Harmonic Timing Generator, connected via a ribbon cable. When paired, the scanner inputs automatically link to the HTG outputs through a sine-wave circuit, allowing the two modules to function as a sine-wave oscillator. Together, they enable harmonic interpolation and the creation of intricate, evolving timbres.
