I managed to get the 1.3 chip
but bean still sounds much better version 2.1
Are you in a position to post the ROM binary? It would be very welcome.

And I agree that the bean has always sounded better, but that's a matter of taste, I suppose.

My suspicion is that the processor is not getting valid boot instructions from the EPROM and then goes quit.
Dump the ROMs and verify the checksums.

Re: Yamaha tx16w

¿Could you please upload the service manual of the TX16W? It has a lot of pages and I don't have time at the moment to scan the entire thing properly. I want to do it someday, but the best I can offer right now is to help you troubleshoot whatever specific problem you may have, or try to answer a s...

Re: Kawai K3 Keys Dead?

If it is the channel/voice out, how can it be solved/repaired? I'm going to take a bit of a "shot in the dark" on this one and say that I would start with the SSM2044 chips. My general theory would be that they are in sockets, so if you remove all six of the SSM2044 chips then none of the voices sh...

Re: Gotek and FlashFloppy E34 error

I've just started playing around with a gotek for Amiga and received the F-F error. "F-F" isn't exactly an error. It usually means there's no USB drive connected. Double-check that the USB drive works by reading it in a computer. Make sure it's a FAT formatted volume. It's not unheard of for USB dr...

Re: ENSONIQ TS10 & TS12 users

I'm trying to find my sound disks (lost somewhere in the house years ago). Was searching the net for some disks when I found this. http://zine.r-massive.com/ensoniq-ts10-ts12-archive/ If you don't have a floppy emulator such as Lotharek, Gotek+HxC or Gotek+FlashFloppy then making disks will require...

Re: JX-8P Displays "Roland JX-8P 12"

After transporting my JX-8P home, it just hangs on the "Roland JX-8P 12" screen. When I disconnect all cables from the power supply and turn it on the voltage increases on the 15v rail to about 24v and stays there. Never had that issue, but it seems like you're barking up the right tree for this. J...

Re: JX3P just plays single repeating tone and some of the buttons change it?

It's predictably like this between power cycles. 14 and 16 are interesting because the 0 light blinks as well in time with the front panel LEDs. The rate of blinking on the pulse light seems to vary. It occurred to me that measuring the output side of IC46 isn't going to work well because you're es...

Re: JX3P just plays single repeating tone and some of the buttons change it?

I love how relatively simple these machines are, almost crudely simple compared to a modern computer, to the point that I feel like I could actually understand what it's doing. All the input pins are constantly high. 11-18 output pins are high with some blinking between 0 and 1. 20 is high. 19 is n...

Re: JX3P just plays single repeating tone and some of the buttons change it?

Some of the pins on the other side of IC46 stay on 1 but go to 0 for a fraction of a second before each iteration of the repeating sound (if that makes sense). To begin to answer that, it might be helpful to look at some theory of operation. Snooze... :D THEORY OF OPERATION What is IC46 and why sho...

Just to restate, the pitch bend wheel works when using the DX7 as a MIDI controller for a softsynth.
Pitch bend range set to 0 in the DX Function Mode?

Re: JX3P just plays single repeating tone and some of the buttons change it?

I guess that eliminates the front panel from causing the issue? Unless it requires a certain signal from the front panel board to disengage the test mode? Not so much a signal from the panel board to disengage test mode, but more that the mainboard sees buttons 1-6 and 9 (either individually or any...
