Re: WTB Oberheim DMX Cowbell voice card

I saw those links, but I would gladly pay for an extra voice card as it would be easier (and less of a chance to screw something up) for me to just pull the entire card out than just one chip when I want to switch back and forth.

I wish I had extra (empty) voice cards for the toms, too.

Re: Modding a synth: disrespectful ??

I'm all for modifications in most cases. Using examples: My CE-300: It's a little battered, and besides, the modification is mostly internal: http://www.gearslutz.com/board/electronic-music-instruments-electronic-music-production/766045-boss-ce-300-mods.html. In general, component or CPU replacement...

Re: Anyone interested in aftertouch for analog synths?

I noticed over in General Synthesizers that you might be doing them for Juno-106. In that case, will it transmit the aftertouch over MIDI? Also, could replacement aftertouch strips for synths that already came with them come later down the line? Some are rather insensitive - Roland from the mid-80s ...

Re: Dream Synth(s)

Looking at what I have, I think I'm set once I get everything working (OB-Xa screwiness, JP-8 calibration, JU-2 dead aftertouch and occasional chorus cut-outs). The only thing I really need is some DMX voice cards / chips - the electronic kick and snare and the conga, and then I'd replace the shaker...

Re: OB-Xa pot board issues?

The new 4051s came in. They didn't work. I put the old ones back in...the OB-Xa sprang back to life! Apparently some were in backwards! :oops: (where's a facepalm smiley when you need it?) Now I'm back to where I started, roughly - tuning and control issues, and I've narrowed down the causes. Many o...

FOUND arpeggio rate selector slide switch for Jupiter-8

I am fortunate my Jupiter-8 has arrived with mostly cosmetic issues. I will be needing the stuff I listed in the title. Now need arpeggio rate selector (3-position slide switch). For some reason, the 2-position and 4-position switches are easy to find, but the 3-position is really rare. FOUND: Screw...

Re: Unresponsive OB-Xa - pot board issues?

i had a problem once with pot boards. i can remember i've replaced 4051 on pot board and it started working again I noticed that there are three 4051s: ICs number 1, 5, and 6. Which way do they go in? (as in, which way will the writing on the chip be facing when the lid is flipped up - read top-to-...

Re: Unresponsive OB-Xa - pot board issues?

With the pot boards disconnected, IC 5 of the pot board measures +0.771V and -0.826V at 7 and 16, respectively.

Re: OB-Xa - power supply issues?

Another observation: On the pot board, the +5.6V and -5V on IC 5 are instead fluctuating and unreadable. Reading it on the oscilloscope reveals a square/pulse wave. The connector that should be +5.6V between the pot boards is also displaying this square/pulse on the scope. Can a problem on the pot b...

I was following the service manual's instructions - measuring across the 10K resistor while the unit has been off for over five minutes.
