ER-301: Sound Computer
for Eurorack Modular Synthesizers

The ER-301 is a voltage-controllable canvas for digital signal processing 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.

3 panel flavors are available.

APRIL-2017. PLEASE TAKE NOTE!
The ER-301 hardware is mature (revision 7) and robust, but there are a few things that you should note before purchasing:
  • There is no manual (yet).  Why?  See next point.  However there is a very active forum where you can get help and ask questions. 
  • The software is still under heavy development which means frequent updates and bugs.  The good news is that typically any bugs found are fixed within a few days.
  • There is a substantial lead time.  I can only make a few per week.  Once you order, I will contact you with your estimated shipping date.
