ER-301 Select Bus Modification Possibility


I realize the ER-301 can’t natively talk over the select bus via the power cable. Is there an extra UART pair anywhere on the module that can be used to break out MIDI communication and add the necessary (simple) parts to interface with the select bus?
The benefits of this would be preset saving across a system along with shared clock and other data.
Obviously FW wold have to be written to handle this communication.


There is an exposed UART which is labeled on the back of the ER-301. It also doubles as the i2c port. However, although I’m willing to assist DIY activities, I don’t see myself personally working in this direction.
