"First experiments with my new Buchla 200e system in combination with my Eurorack gear. Dual Maths going through Format Jumbler and some Vulcan Modulator thrown in for fun."
"Taking a voice chip out of a Roland Juno 106 and sticking it in acetone to strip the resin. I figured out that Chip 4 was bad in my unit. I've never done any kind of electronics before so this just shows you how easy it can be (with a healthy dose of patience and a steady hand).
First you should figure out what chip is bad. You can do this by powering on the unit while holding the key transpose button. Then hitting a key and watching the display cycle through numbers 1-6. If nothing plays on a number or the sound sustains on that number (hit different notes to hear it change pitch) then you know what chip it is.
There is a great video on youtube that shows you how to strip the resin off a chip and hopefully repair it. This is apparently due to overheating and conductivity due to the old resin.
Taking it out of the unit is pretty easy and you can search youtube for videos on how to open up the 106 and get the board out with the voice chips attached.
I have never done any electronics work before so I practiced on an old VCR for an hour. I learned how to take out components and solder them back in until I felt comfortable.
It helps if you have a few drinks before hand to steady your hand and nerves. Ok, probably not but it was Saturday and I'm all about the tequila on a Sat afternoon with nothing more to do than some trial electronics work.
In part 2 I'll figure out how to strip the resin and re-solder the chip back into the board and re-install into the 106 to test.
All credit where it's due just google 106 repair and you'll see the videos I watched to learn how to do this or look up
"This controls all functions of the Drumstation that are controllable via MIDI messages -- tuning, volume, pan, cut, distortion, etc. Every voice is represented visually with all it's parameters in easy to read graphic colors. Nice for tweaking the sounds as your sequencer plays the music without having to do so at the front panel of the unit. A very simple page in the environment but with all the parameters for both the 808 and 909 sounds on screen at the same time. All real time tweaks are recordable by the Logic sequencer for real time changes on playback. You may also remotely control these SYSEX faders and buttons via a hardware control surface if you take the time to program the faders for your individual hardware. This is easy to do and needs only be done once and then saved.
This will run on any currently tested version of Logic Audio (Mac or PC). It was created in Version 3.5 -- and has been tested extensively to work in all versions up through Version 9 (Pro or Express). (PLEASE NOTE: It has been tested with LOGIC PRO 8 but it requires the version 8.01 or higher as 8.0 SYSEX did not work). Just use "Open" to load the environment as a song document -- notes on operation are provided with the software. It uses one page (layer) in the environment. It works via the sending of SYSEX and/or CC messages from Logic via MIDI to the receiving hardware device. Please see the picture I posted here to give you an idea of how nice this software looks and how it will function.
This software ABSOLUTELY requires LOGIC to run (versions 3-9, Mac or PC) -- it will not run as a stand-alone editor or with MicroLogic or any of the other earlier neutered Emagic Logic offshoots. It WILL run with Logic 5 SILVER."
