This instrument is made up of two lightly modded Benjolins.
I’ve found that Benjolins play really well together and two units is a whole lot better and crazier than one.
-Oscillator fine tune adjustments.
-Oscillator rate indication LEDs.
-Jacks for all of the outputs and adjustable inputs for the VCOs and VCF.
-A Rungle clock input jack which you can read about here.
-A four channel mixer for mixing the two Benjolin signals as well as two other signals (like the XORs or straight VCO signals).
-Switching bi-polar power supply.
-Banana to 1/4″.
