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
Studer A820 controlled by serial remote controller, resoldered 9pin cable (different studer pinout) to a usb-serial converter directly to Max/MSP (M4L) in Ableton Live. Now it reads the timer, but i will add some more functionality like biasing other audio parameters as well:) its unbelievable how future proof the whole design in the mid 80´s already was!!! What drove me crazy (together with Deborah and Daniel as well, thx for your help my friends!) was that Studer did not really document their special pinout for the serial connector. more info…read more
This lovely Linn drum/DMX/Drumtrak 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. Check out www.jacobkorn.de/studio for more infos on mentioned projects!
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
Duration 6h for Mods: 300€ + parts (knobs+housing) + postage (german clients + 19% tax) 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! 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…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
