Yamaha DX7 SuperMAX Redux

Something else I’m working on…

SuperMAX plus LCD screen

SuperMAX+ LCD welcome greeting

The new circuit boards just arrived and the testing so far is good. The boards are a slight improvement over the original: I’ve increased the size to allow for a screw to hold the board down and I’ve added a battery holder (not installed) for folks that might want to make a better setup for the CR2032 RAM backup battery.

    What does the Supermax cost?

    Price varies a bit depending on parts cost, best thing to do is check my eBay page for current and past sales. That will include information on shipping as well.

    While playing with the DX7 I also started toying around with the idea of burning ROMs for user ROM cartridges or perhaps for allowing people to customize the patches in the EPROMs supplied with SuperMAX or E!.

    So far I’ve captured the ROM binary data for:
    – the 256 presets in the Grey Matter E!
    – the 64 presets in the SuperMAX
    – the 64 presets in the Yamaha Factory DX7 ROM3 cartridge

    The patch (voice list) appears below. I really hate that there are so many terms for “patch”, “preset”, “voice”.

    Note that this is taken literally from the EPROM in the cartridge. I believe that in the EPROM the B bank appears before the A bank.

  7. J. P. says:

    Any way to expand the TX7’s memory?

  8. grantb4 says:

    I have never heard of one myself. Maybe there are some solder-on RAM expansions though. I thing the problem is lack of space in the TX7 and that other than the EPROM, everything is soldered in. There are some good Yamaha Groups on Yahoo that may be able to answer this more definitively.

    Hi,

    can you tell me if and/or when the supermax will be available again? I would like to order one 😉

    Greetings,

      Hi, I just pulled the most recent listing off a day or do ago. I’m off to the CES 2016 show and will relist it when I get back. So around 2016-01-10 probably.

  10. Gustavo Fourcade says:

    Is it available for DX7II?
    TIA,
