Voltage-controllable canvas for DSP algorithms

One of the many characteristics that attracted me to modular synthesizers is that they enabled me to make the kind of music that I love away from the computer. However, not all digital audio tools can be elegantly and efficiently realized in a dedicated hardware form. So, I either had to deny myself those tools, or, go to the computer. The ER-301 is the culmination of 2 years of sweat and tears spent creating a third option.
