Re: DX7 ROM Card with 256 x 32 patches

Maybe this is not problem IMHO, as such card with 4096 or 8192 patches and limited possibility to reprogram (becauser most of potential users have no access to and not enough knowledge about EPROM programmers) can be inside instrument all the time, like glued :-)

When there’s a need for more sounds, there’s still internal RAM and SysEx communication.

Thank you for posting this. As Daniel has mentioned there is perhaps a large amount of pent up demand for something like this. Is there no issue with using the PCB traces as contacts? I know this has been done in the 80's and 90's but it seems all the recent attempts (even here on this group) have failed to achieve popular success because of board thickness or some other issue making them unreliable. I hope yours does work.??
