Roland 80017a Chips Removal - GR-700 MKS-30 Juno 106
YouTube Uploaded by WayneJoness on Apr 11, 2012
"http://www.joness.com/gr300 This video shows the removal of a 80017a chip from a GR-700 printed circuit board. The tools I used were a Radio Shack 30 watt soldering iron, desoldering wick, soldering helper, and Caig DeoxIT D5. The basic Radio Shack 30 watt soldering kit has almost everything your need. I find that spraying the Caig DeoxIT D5 between operations helps keep the PCB clean, and helps the old solder flux move on to the desoldering wick. After I have removed the solder from the pins, I used the soldering helper to line the pins up, then gently rock the chip back and forth to make sure everything is loose. Rather than pull the chip out, I first push on the pins on the soldering side, then gently tug at the chip. It comes right out. If you have not tried this before, I recommend practicing on some spare parts, as this can be tricky and frustrating."

Gotharman's Yamaha CS Filter _ Demo 1
YouTube Uploaded by DJjondent on Apr 11, 2012
Audio on left channel only.
"Built in Denmark by Gotharman. Uses original Yamaha IG00156 filter chips removed from old CS80,CS60 and I think also CS50 synths.
(I hope the synths were already dead and that no one was harmed when this was done) :-)
Because of the limited number of these synths these modules are no longer produced.
Check out the GotharMusic site:
http://www.gotharman.dk/index.htm
They seem to like old yamahas.
Check this old CS 20 :

Anyway,
This CS 80 filter module has 2 cv modulation jacks.

Teenage Engineering OP-1 timestretching how to
YouTube Uploaded by darenager on Apr 11, 2012
"A quick tutorial how to timestretch a loop on the OP-1, it is a bit of a hack but works quite well in a lo-fi way, here is how it works, the value LFO is assigned to loop direction, with a fast speed the tempo will change without affecting the pitch, seems to work best with vocals or beats. Enjoy!"

RIP Thereminist Barbara Buchholz

Today we lost one of the great theremin players of our time. Barbara Buchholz was a master student of Leon Theremin's grand neice, Lydia Kavina. Do not miss her performances below.
via Wikipedia: "Buchholz was born in Duisburg. She studied flute, guitar, bass guitar and singing at the Bielefeld University. She earned her first success as a bass player in the German woman jazz band Reichlich Weiblich.[1] Since the early 1980s she worked on various interdisciplinary projects both as performer and composer. She produced e.g. Tap It Deep - „midified“ Steppdance and music, Human Interactivity and Theremin: Berlin-Moscow.
At the end of the 1990s Buchholz met Lydia Kavina, the grandniece of Léon Theremin; later she went to Moscow and became a master student of Kavina. In jazz and contemporary music she develops new playing techniques and experiments with various sound possibilities for the theremin. Together with Kavina, in 2005 Buchholz founded the Platform Touch! Don't Touch! for theremin. New compositions for the platform were worked out amongst others by Moritz Eggert, Michael Hirsch, Caspar Johannes Walter, Juliane Klein, Peter Gahn, Gordon Kampe and Sidney Corbett. Buchholz performed in a trio with Norwegian trumpeter Arve Henriksen and live electronics performer Jan Bang,[2] tours with Jazz Bigband Graz in the framework of ELECTRIC POETRY & Lo-Fi Cookies and conducts solo performances as well.
She played the theremin in various contemporary works, like The Little Mermaid, a ballet by John Neumeier, music by Lera Auerbach, and in the operas Linkerhand by Moritz Eggert and Bestmann-Opera by Alex Nowitz.
In 2009 Buchholz participated in the talent show - the German version of Got Talent - and succeeded in presenting the theremin to a wide audience.[3][4]
She died of Cancer on April,10th, 2012."
