Direct access to all frequency bands

This expander module gives you direct access to the 10 frequency bands of the Erica Synths Graphic Resonant Filterbank. This eliminates the need to raise and lower the bands manually using the buttons on the main module. This makes sound shaping with the Graphic Resonant Filterbank much easier. The expander only works with the Graphic Resonant Filterbank and has no function without it.
