Hi Nicky, Glad to hear you got all the voices to load. The performance bank uses the patches in the voice banks. If you load a new voice bank the performances...
Hello, on my broken power supply there are several outputs reading: +5v, +12v, -12v and D.E. and A.G. My question is; what are D.E. and A.G.? I suppose they...
I should imagine a highly filtered low noise one is best - ie expensive as opposed to cheap. You don't say what is actually wrong with the power supply - have...
Hi, I have no power at all. It is a long story what's happened: After I left my DX on overnight a fuse was blown. After changing the fuse there was still no...
It's been a few years but most of the repairable ones were related to several things that I saw repeatedly. Simple readily visible cracked solder connections-...
Hi Gregg, capacitors are all changed, so are the other important and more delicate parts. I hoped it was something simple as that, but it wasn't. I've checked...
Frank, Â The resistances you measured are probably "in-cicuit" meaning you are also measuring everything in parralel and series with the transformer windings....
Hi Gregg, I didn't measure the resistance of the transformer T1 in-circuit, so it is the actual resistance. Since I'm getting 332.1 volt on pin 1 and 2 of T1...
Oops, accidently replied on a group-posting instead of a private message. Hope it didn't cause some inconveniences. If it does, I'm really sorry. Shouldn't...
Frank, You misunderstood me or I wasn't clear. Probably the latter. That formulae is for the intended secondary AC voltage. Say if you want 5VDC with a full...
Hello list. I am considering servicing my TX81z to bring it up to "current". This involves a new EEPROM (1.1 to 1.6) and I would also like to add the metal...
Hello, I replaced the EPROM last month on my TX81Z (serial # 1903). I used an surplus EEPROM from an old PC motherboard salvaged from the dumpster of a local...
After twenty years of service the battery in my trusty TQ5 finally carked it. I was not too concerned because I had a sysex back-up. My problem arose when I...
well according to the yamaha black boxes forum (which has photos of changing it) the battery on a tx81z is a CR2032. there are no schematics though for the tq5...
I've taken a TQ5 apart to clean spilled liquid on the inside of the LCD display screen. I remember taking a lot of notes during the process. I listed every...
Thanks for the input. I'll probably grab a willem programmer, they have them for $30 on ebay and I like the large variety of parts you can do with it As far...
Speaking of TX81Z rom version 1.1, can you dump that rom and post it to the group? Neither 1.1 nor 1.2 are dumped yet, and I'm curious as to what the exact fix...
Sure will. May need some hand holding though, this is my first foray into eprom land and i am sure it is a little different than the PIC/AVR stuff I am used...
I'm sure most of you heard of the well known grey matter upgrade for the DX7.I recently obtained a ser-7 upgrade rom from a fellow member on this group.I have...
Heya, peeps! I've been setting up my music stuff, the youngest bit being over 15 years old, all the way back to the oldest, my DX7 mark1. Well, I pulled out my...
Hi Greg, The Midiman Midisport is a decent product. I have two 1x1's and a 2x2 that I use on several PC's. Though I can't speak for an OSX Mac I've never had...
Hey Greg, Check out the Edirol (Roland child) UM-3ex interface. I got that recently when I upgraded to a new iMac from a 10 year old Mac system. It's a USB2...
... That looks like a nice option. At least I know the Roland name, and it sounds like the offspring is following in the father's footsteps. :) 3x3 would give...
Yes, you do already have a nice little music system! Not too many technological distractions. I had the same Mackie 1202, which was nice until it crapped...
There is currently an Ebay Listing a DX7IID that has the word "Plus" after the DX7IID. The seller (Technoempire) doesn't know if any additional features are...
If it is a Grey Matter E! upgrade, it is noticed on the case of the DX7, I have a DX7IIFD with Grey Matter E! cheers, Marco fish2fish21227 schreef: There is...
Take a look at the pictures (item 170404127071): The DX7II-D plus has a floppy drive, the DX7II-D doesn't. The DX7II-D plus button #16 has no name. The...
