Wild Stream
wildstream is a touch-play filterbank resonator instrument.
Left
filterbank and noise control:
The left touchpad controls the switches of 10 different bandfilters, divided into two groups: the upper group consists of 61Hz, 218Hz, 777Hz, 2.8kHz, 11kHz; the lower group consists of 29Hz, 115Hz, 411Hz, 1.5kHz, 5.2kHz. Sliding your finger on the touchpad controls the switch amount/volume, with the upper group increasing upwards and the lower group increasing downwards.
The middle horizontal part of the touchpad is the noise trigger area, with the left side triggering pink noise and the right side triggering white noise. The noise, once triggered, enters the filterbank.
10 cv inputs control the volume of the corresponding 10 bandfilters, with the filter Hz number gradually increasing from bottom to top: 29Hz, 61Hz, 115Hz, 218Hz, 411Hz, 777Hz, 1.5kHz, 2.8kHz, 5.2kHz, 11kHz.

Input:
Two independent inputs are controlled by two faders to control the gain independently. The input audio enters the filterbank. The two inputs can accept audio levels from touch microphones, line to eurorack levels, controlled by the faders. The two input ports also support passive microphones (6V power supply).
filterbank feedback:
The left bandfilter is divided into upper and lower groups, with two faders controlling the feedback amount of the two groups respectively. The frequency control range of the filterbank circuit design is overlapping, so when the feedback amount of either the upper or lower group reaches a certain level, self-excitation will occur. The two groups of feedback only work within the filterbank module;
echo feedback:
The feedback amount of the echo effecter is controlled. This feedback only works within the echo module. Appropriate feedback can make the echo/delay effect more realistic, and excessive feedback can cause the echo to self-excite.
echo mix:
This knob controls the dry/wet signal ratio of the echo effect. When turned completely counterclockwise, only the dry signal is present, and when turned completely clockwise, only the wet signal is present.
output:
The output volume fader controls the volume of the upper group audio output, lower group audio output, and total audio output simultaneously. The total audio output mixes the audio of the upper and lower group outputs, and all three audio outputs are monaural.
The stereo line output volume is controlled by the line volume control knob next to it, which outputs the upper and lower group filters in the left and right channels respectively, and reduces the volume to the line level.
Right
The right side is the touch control of the timbre and echo two effectors, with the upper and lower groups separated, that is: upper group filter-> upper timbre-> upper echo-> upper group output; lower group filter-> lower timbre-> lower echo-> lower group output, the touch control is also separated into upper and lower groups, so there are actually 4 touch control panels on the right. Sliding up on the touchpad increases the depth of the timbre or the delay amount of the echo.
Six cv in ports are arranged from bottom to top as follows: pinknoise volume control, whitenoise volume control, lower group echo delay amount control, upper group echo delay amount control, lower group timbre depth control, upper group timbre depth control.
wildstream is designed with reference to the serge eq circuit.
