Stereo mixer and scanner with VC panning and scan center/width In a minuscule amount of space, the Scan & Pan provides a 4 channel mixer with voltage control of level and panning. Its signal path is all discrete transistors.
Each channel has a mono input and a gain control. The level can be set manually with a fader and modulated by a CV. Furthermore there's a panning function with a manual potentiometer for determinig the channel's panorama position and a CV input for modulating it.
In the dark highlighted, right part of the module we find the L and R outputs as well as the scanning function: The "Center" parameter is used for selecting a channel, while "width" also selects the adjacent channels. For instance if channel 2 was selected with center control and remain static, it is possible to fade in and out chennels 1 and 3 (or even 4).
It can be interesting to use this function with different waveforms of an oscillator but also with totally different signals. It can be even more exciting if the channels have different panorama positions which means the channels which are faded in appear in different stereo field positions.
