has the orginal battery.How can this be after so long?Im new to the group and I see a very to easy to read how to on this group.I have experence changing and...
Hi W_A_C, The TX81Z has a very small memory capacity (by today's standards) so the battery doesn't have to deliver much current to hold the data. Also if your...
Hi everyone, I finally got a TX802 off ebay a short while ago - yay!! So I finally got around to actually trying out my Behringer BCR2000 controller on it. It...
It makes sense that the dx100 would not receive the preformance and the wave shape data on the operators as it lacking thoses features.So my tx817 say its ...
I see you already know about the 4 ops and their capabilities. Cool! Version 1.3 will send/recieve sysex without any fatal issues. There is a Service News pdf...
Hello, I have been fooling around with the TX81Z for about twenty years now. I have developed a stand-alone editor for it (and the TQ5) that changes 28 of the...
No,  This uses a little microprocessor with only 1024 bytes of RAM. It loads the parameters for one voice (the current voice) and reads the slider for the...
I found a dusty old TX81Z at the local thrift shop. I know. Seriously. My jaw hit the floor when I saw it. I already own one, and the entire way home I was so...
its more likely the smothing caps of the dac and the buffering opamp circuit after the dac that is at fault is the sound all right through headphones if so ...
get awave studio it can save instrument files to typhoon and wo1 ample format and tx16w instrument format so you can take soundfonts and change them to tx16w...
I tried the headphone jack and it's the same problem, but twice as bad- I can't even hear the voices, just the static distortion. It's quite loud. To give a...
I have seen this problem three times in the last few years but in other synths. I bought a DX7 with horrible distortion and it was the LF356 op amp right after...
Yes Alan, I would be interested in your controller. I have a TQ5 and 2 TX81Z's. Plus an assortment of other DX, TX, SY, and TG gear. I can help with...
it sounds like you need a cap replacement on the dac and the buffering opamps and the line level opamps they are tantalum beads or ceramic disks depending on...
that sounds like the dac if replacing the dac make sure you replace all the caps as these are used in the conversion also change the opamps to the same model...
I doubt if it is possible to replace the DAC IC on the TX81Z. It is a custom Yamaha IC and it is probably impossible to get. This is a serial DAC that has...
i would be interested in a controller that would work with the tq5 and fb-01. pots are fine instead of sliders. ________________________________ From: Alan...
Weird coincidence I already had a copy of that distorted Oboe sound. I can hear the undistorted TX Oboe sound in the background. Then whenever the distortion...
What DAC is it? GB ... From: jammie To: yamahablackboxes@yahoogroups.com Sent: Tuesday, November 03, 2009 10:53 AM Subject: Re: [yamahablackboxes] Re: TX81Z...
Yeah it looks like a special parallel-to-serial chip followed by a serial DAC. Maybe some of the crappier Yamaha products use the same chips? ... From: Alan...
the dac is a burr and brown dac and is not a yamaha part yamaha have a part number for it xa566001 but its not made by them you can still get them pcm54hp burr...
hmm... are we still talking TX81Z? my schematics list a Yamaha custom chip (YM-3012) as the DAC. this is a serial device while PCM54 is a parallel device, so I...
my bad looking at the wrong schematic ym3012 is a yamaha part and was used in many games machines ill post this dac to the files section you can get them for...
