Arduino based Probabilistic/Random trigger with 1 input & 5 outputs, dedicated to modular synthesizers.
There's 1 gate input and 5 gate outputs.
When gate signal comes to the input, it is distributed to the 5 outputs following the chance setted by its dedicated knob.
When knob is at 0%, there's no chance that the output will reproduce the gate signal.
When knob is at 100%, there's 100% chance that the output will reproduce the gate signal.
I also added a "Pattern mode" switch. It allows to choose between Random & Pattern mode.
Random mode is the normal mode.
In "Pattern mode", each of the output will follow a rythmic pattern. The knob will let you choose the pattern.
There's 62 different patterns available, with various lengths.
This is very helpful in order to create polyrythmic beats.
6x 1k resistor
1x 100k resistor
5* LED (red)
5* 10k potentiometer
2* 1N5817 (Shottky diode)
1* TL074
1* TL072
4* 100nF
2* 10uF
1* switch
1* arduino (nano, but others might work, give it a try and tell me!)
6* jack socket (1 in, 5 out)
Be sure that all jack sockets grounds are connected together !
TL072 & TL074 op-amps works with 12v/-12v, which is very common in modular system. If you want to make this project with an USB or 9v power socket, you will have to choose other op-amp in order to buffer the gate outputs.
