Re: Yamaha DX7 E! Grey Matter & Corrupted Memory

... I've done that reset twice, and still have no effect when I try and transfer patches. I've cleared all the banks, and they are all INIT VOICE and uncorrupted (default sine waves). I'm getting a new MIDI-USB cable tomorrow, a YAMAHA UX16, which hopefully fixes the problem. The cable I was using ...

Re: Yamaha DX7 E! Grey Matter & Corrupted Memory

Following the E! Grey Matter manual's procedure was my first intention. They suggest: Turning off internal memory protect, enabling SYSEX filters, and ensuring midi channels are set to 01. After I set these settings, I send the SYSEX files and watch blocks of hexadecimal patch text fly by and then o...

Re: Yamaha DX7 E! Grey Matter & Corrupted Memory

The rabbit hole goes even deeper... At this point I've messed around with midi settings and tried to send sysex data to the synth like 20 times, and now, when I cycle through the patches of bank 0, something familiar comes up on the MIDIOX Monitor MIDI IN. The DX7 is having a blast saying that it kn...

Re: Yamaha DX7 E! Grey Matter & Corrupted Memory

Unfortunately my e! grey matter is long gone , so I can not test it. But I am sure that memory protection should be off, "SYS INFO AVAIL" should be set to yes, and the midi channel should be set to 1. Mem. protection is off, and I'm not sure how to get SYS INFO AVAIL displayed on the screen? Origin...

Re: Yamaha DX7 E! Grey Matter & Corrupted Memory

According to this page, I should "push button 2 (Midi in filters: SYSEX) and then "on". This enables SYSEX data transfer."

Is this info wrong, is it actually turning SYSEX off?

Re: Yamaha DX7 E! Grey Matter & Corrupted Memory

I just purchased the Yamaha UX16 Midi Transfer cable, but are you sure my cable is the problem? HOSA Tech is pretty decent stuff, it's priced high but I couldn't see it any worse quality than the third cable you posted. Is there anyway to tell if it's the cable's fault or the synth's fault? It seems...

Re: Yamaha DX7 E! Grey Matter & Corrupted Memory

The manual for the DX7 Mk.1 E! is here. The reset process is outlined on pages 4 & 3 (yes, out of order - the scan's a little weird.) Ok, now all banks and voices are default back to INIT Voice, normal uncorrupted sine wave. MIDIOX also picks up when I press keys and display that in the Monitor out...

Yamaha DX7 E! Grey Matter & Corrupted Memory

I recently bought a $167 non-functioning DX7 off craigslist, and am now stuck in the process of fixing it. The synth's patches made no noise, and all were corrupted on the display, all sorts of misplaced characters in the title of the patch. I assumed all I would need to do is reload the patches and...
