it's done. i scavenged a few IR chips out of a Juno 6. the rest of the parts needed-a couple IC's, diodes, sockets-i all had laying around. i had some leftover black walnut from another project; it was enough to knock up the end cheeks. kenton midi got installed. recapped the PSU. thoroughly cleaned...

am i detecting a slight element of something along the lines of... "synth bargain pissing contest", or maybe its just me?

thanks! was looking in the wroooong part of the schems altogether.

Are you seeing a 15V gate on the collector of transistor 16 for that voice when you play a key associated with that voice? no, it's NOT!!! is that where the incoming gate signal meets the module board? on the working voice, it's going 0-10V(assuming the middle pin is the collector), but on the non-...

hi all, im rehabbing a JP8, and one voice has a gate that isn't opening. at the TP, it shows an offset of about -.9V. (lets call it 1A; 1B works properly). i'm having a little trouble understanding how to trace the source of the gate within the module board. i KNOW the issue is local to the module b...

some days, the bear gets you. i happened to get the bear that day. for the record, it needs work. voice #5 is dead. the mod button is either shot, or needs an extremely thorough cleaning. the whole thing is massively out of calibration-autotune doesnt get the remaining 7 voices in tune enough to rec...

Steve Jones hit the nail on the absolute head. I would say the CS80 is the #1 most absolute enjoyable synth to sit in front of and play-of all time. I consider the layout to be on par with the ARP 2600-arguably the most intuitively laid out polysynth ever made. If you want a synth that is a recordin...

Holy s**t this thread smells like f**k nerd There's nothing you can do that is quite as "f**k nerd" as pointing out how "f**k nerd" a thread is that you're reading, responding to, and which applies in some way to you. :thumbleft: congratulations, you pointed out with stark, pragmatic clarity the na...

M-Audio wireless MIDI in action:

read the part off the actual part in the circuit board, not the schems. in list form. on here. someone'll help.

are you calibrating scale because it sounds out of scale to you, or because you think this is something you should do? its a question worth asking. i am going to tell you right now that if you are planning on tuning the voice cards, and you dont have experience tuning synths, i will bet you $100 th...

AFAIK, C0-C5 typically refers to the actual, physical key.

hey folks, hope you may be able to help me. here's the service manual, the pot board is on page 53: http://www.synthfool.com/docs/Oberheim/Oberheim_OBXa/oberheim_obxa_service_manual_3.pdf and here's the problem: a number of panel switches on my OBXA are inoperable, or intermittent. they ALL lie alon...
