Dual Specular Benjolin

BE2N is a 22HP eurorack module with two specular Benjolins at its core.
It is intended as a re-design strictly for no-commercial use.
Use it to test and expand your soldering abilities and to investigate this incredible circuit and its sonic capabilities.

1F - Oscillator one frequency
1V - Oscillator one frequency input modulation
Normalled internally to Benjolin Two oscillator two triangle out.
2V - Oscillator two frequency input modulation3
Normalled internally to Benjolin Two oscillator one triangle out.
2F - Oscillator two frequency
XI - XOR4 input
CI - Clock input
2O - Rungler bit 2 out – blue led
The order of operation is pin 2, 12, 3. These outputs are great drum triggers.
3O - Rungler bit 3 out – red led
1R - Rungler amount on oscillator one
1V - Attenuator of oscillator one frequency input modulation
2V - Attenuator of oscillator two frequency input modulation
2R - Rungler amount on oscillator one
LO - Rungler loop offset
02 EX - Switch to select the Rungler shift register clock source: from oscillator
two or from an external clock plugged in CI input
1O - Rungler bit 12 out – green LED
T1 - Oscillator one triangle out
P1 - Oscillator one pulse out
P2 - Oscillator two pulse out
T2 - Oscillator two triangle out
XO - XOR out
RV - Rungler CV input
01 LP EX - Switch to select the Rungler shift register serial in source: Oscillator
one (Rungler signal), loop or external input
EX IN - Switch to select the filter audio input - from an external signal or from
the internal compared oscillators waves
IF - Filter audio input
AA - Filter audio input attenuator
LV - Filtered out level
MO - Main Out = Filtered out
FF - Filter frequency
FV - Filter frequency CV input
Normalled internally to Benjolin Two oscillator two triangle out.
FA - Filter frequency CV input attenuator
RF - Filter resonance
FR - Filter Rungler amount
FS - Filter Sweep
It sweeps the filter cutoff up and down, controlled by the triangle wave coming from oscillator two.
VA - Vactrol VCA input - it effects the MO - filtered out
PM - PWM out
