They always say stuff like that. They work on a timeclock. They gotta make money with every job. I can take 10X as long if I desire. Point being, the digital components are most probably still

Have your tried to replace OS Eproms? Have you done diagnostics test? There were some reports about noise at the outputs in some series of TX802 - solved by replacing opamps. Problems with sound

If it is software problem, than replacing OS Eproms (three pieces) can help. But this can be hardware problem. Daniel Forró

It is not recommended to replace all caps, only the bad ones. Service experts say: If it works, leave it so. Daniel Forró

This is true. Plus, do not hesitate to change out the tantalum caps on the digital boards, too. Many electrolytic have been changed only to find problems in data addressing and especially at boot.

Nothing gets changed in the patch. This is not like a memory corruption problem. What is happening is that what the display says does not match the sound the machine makes. For example, the display

I would troubleshoot with a midi editor like SoundQuest or whatever to see exactly what gets changed realtime. With an init patch you may be missing something. If you get the other operator levels

Hi, I did a full recap of the TX802, and it sounded awesome afterwards. Electrolytic capacitors are dead on most 80s Yamaha Roland Korg gear. To change all capacitors is a PITA, but the machine

Hello group, I would like to share a troubleshooting story I am in the middle of. I bought a broken TX802 on the internet. I knew it was broken when I bought it, I felt like taking a chance. The

Hello! I actually checked that no "All Notes Off", or any other message, get transmitted through MIDI when Tch is changed. It is an internal behavior of the synth, not related to what goes onto the

I??d suggest connecting the V50 out to a midi analyzer to see if the V50 sends an All Notes Off message when you switch the Tx Channel. Midi OX on a PC should tell you the truth. Then you can

Hello, Is it possible a midi message filtering? You can filter the data that feed the V50 and exclude other than note, aftertouch, modulation wheel . Just a suggestion. AFAIK the v50 secuencer

Hello, I am the happy, and quite recent, owner of a Yamaha V50. I bought it from the first-hand owner, and the instrument is in near-perfect condition. I am using it to create live music, in tandem

From my notes the PLG150DX and DX200 have slightly different sysex prefixed by F0 43 nn 62. But my 6-operator FM programs were all written to handle individual cases. For bulk conversion, Martin

How can I write about a topic this big when I have never had a 6-operator DX/TX to test it. It looks to me that dx7chan.zip changes the MIDI channel for a DX7 Mark I VCED and what seems to be the

These are all great, thank you very much. There might not have been any actual PLG service manuals; it was vague from the original post what exactly he had, he may have been describing these service

I've gone through all the files I have from the various Yamaha/DX groups I was part of (which I fully archived, which shouldn't have missed anything), but I'm not seeing any PLG card service manuals.
