Micro version of JOVE - Multimode filter, originally by System 80
Warning for DIY beginners - this project is a hard to build with dense PCB and low pitch ic's which requires experience in SMD soldering.
If you care about this project - DO NOT SELL ASSEMBLED MODULES, Build only for your own use!
Plum Audio uJove is 8hp version of Jove - Multimode filter By System 80 that is inspired by the Roland Jupiter 6 filter.
uJuve is exactly the same circuit as the original 14 hp Juve with the same amazing sound.
2 extra modifications have been added to increase the sound variety:
- When no jack is plugged in to input 2 Positive feedback from the output to input 2 is activated. the feedback level can be controlled by LEVEL 2 knob.
- Input 2 level knob can add 6dB of gain, 0dB on the middle, +6dB (clipping) when fully clockwise.
4 Leds of the original 14 hp Jove replaced by one RGB Led
Modes colours: RED - LP24 , ORANGE - LP12 , BLUE - BP , GREEN - HP
About Positive Feedback:
Resonance = inverted feedback
Positive feedback should distort the signal.
In LP2/4 modes (red/orange) the positive feedback alone can make pulses.
it’s better to mix between positive and negative feedback to achieve distorted worm sound. Also try to use input 2 in LP modes and the positive feedback become clipper (attenuation until middle position of the knob and clipping from middle position)
The positive feedback sounds much better in BP/HP modes (blue/green) to achive great distortion.
