kNoB technology Dragon-FLY Stereo Frequency Scanner and Vca Eurorack Filter Demonstration

kNoB Technology

"Demonstration of our new eurorack module. Only raw sound.
Input signals random sequence and saw vco.
Voltage controlled stereo frequency scanner Dragon-FLY fully analog
I wanted to create a flexible and powerful tool,
which can mix a large number of signals and process them.
Inside:
- two multi-mode diode based Sallen-Key 12db/oct filters with constantly available inputs of different types of cut and input attenuators
- two classic ota VCA with lin and log characteristics
- voltage can control the cutoff frequency, resonance level, VCA gain, pan
- both filters can be controlled by one knob with different modes
