AX73 firmware testers needed

Post by rlg42mw » Mon Mar 09, 2020 8:26 am

I am making a new version of the AX73/VX90 firmware with CC support and sysex patch save/load. No other features are being added. I need a few people with these synths who are willing to take them apart and change the EPROM, then test the new firmware to flush out any bugs. I understand that most people do not have an EPROM programmer, so I will offer to mail EPROMs for $10 each to anyone in the USA who is willing to help with the testing. There could easily be several versions of the code, as things are tweaked. Each new version would cost another $10 to cover my costs. Probably it won't take more than 3-5 iterations, and maybe fewer to get things solid. If you are interested, let me know. Of course anyone who has an EPROM programmer would also be welcome to help with the testing and I would email you an image whenever there is a new one.
