If you are interested in modifications of your analog gear or you want to control your 70’s and early 80’s machine with MIDI it might be possible to put a retrofit into it. check out the list of possible upgrades and videos of my midified and heavily modified analog synths and drum machines. I am a graduate engineer for media technology (Dipl. Ing.). Please ask for pricing of your individual project. CONTACT kits for the following manufacturers are available: ROLAND, MOOG, YAMAHA, ARP, KORG, KAWAI, CASIO, SEQUENTIAL CIRCUITS, OCTAVE, OBERHEIM, JEN, SOLINA, LINN,…read more
My first ever synth and also the first to be touched with the soldering iron:) Used the Moog slayer mod with filter FM and also came up with an input to the juicy chorus effect. Legowelt himself described a modification to the joystick where you remove a spring and use the vibrato/filter LFO without holding it all the time…its a nice one too!! http://synthmod.net/korg/moog_slayer/ http://www.strellis.com/poly800.shtml
This lovely linn drum sounding drum machine with 24 sounds and a lot of interesting preset rhythms and fill/break variations. the programming is fantastic and uses a very lively feel (they call it a built in humanizer function). I added an 8ch output multicore cable for arranging and mixing down those instrument groups in a more flexible way.
Jacob Korn takes Telekom Electronic Beats TV into his studio for a Tech Talk with a difference. Watch as Jacob demystifies the seemingly complex world of modifying synthesisers and drum machines. In addition, to Korn’s wisdom, you will also hear 2 demos of what a few modifications can do to your gear, be it Roland, Yamaha or any other brand.

Power supply replacement so we got rid of the hum : http://www.circuitbenders.co.uk/newsarchive/TR77power.html Trigger inputs: http://www.circuitbenders.co.uk/newsarchive/BRA.html Sync input: http://www.adambaby.com/studiotech_TR-77.html http://www.burnkit2600.com/tr-77/
The Danelectro Spring King is a small spring reverb, but there’s also a slapback delay in it, using a PT2399S chip. Thanks to some documentation on the internet I could easily mod the reverb to control the delay. The idea is to be able to get only the reverb signal if we want, and in a general way to take advantage of the delay by changing the Time and Feedback as we feel.Control Delay Time: Between PIN6 (VCO) and Ground, there’s a CMS resistor „362“ (3,6k). Once it’s taken off…read more
Stereoping pointed out some interesting mods for this VCR-looking analog drum beast. Since I like the idea of saving kits i focussed on parameters like tune and decay for real-time control. Triggering those 5 voices by my modded TR-606 with multiple outputs. Great fun! Duration: 6h. Thx for the nice documentation! http://www.stereoping.com/pearl-drx-1-drumsynth/?lang=en The Pearl DRX-1 has 5 Instruments which can be triggered by drum pads. Of course, you can also feed some trigger signals into it. All instruments have the same parameters and are therefore sounding identical, although the pitch…read more
Got this earlier version of the RE-201 in a very bad shape. After a lot of hours, it´s alive again. Replaced all pots and connections, recapped the power supply and adjusted the tape transport that caused a lot of issues. thx to Jacob Stoy who borrowed his RE-200 for troubleshooting. check out the „sound on sound“ mod! quite noisy but fun unit!!! https://youtu.be/VJ9MP76cpNM
