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
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
Ripped from an Top Sound DS organ. Super nice triple bucket brigade chorus…solina style strings!!! using just 1 Roland 100m saw oscillator.
Modded this little Roland TR-909 together with Claudio of discrete-audio-solutions. All mods are switchable to „stock“ sound (except clap noise). Mods: -BD-Tune, BD-Overdrive, BD-Decay Range Extension Switch -Clap Noise Volume -Rimshot Pitch variations switch -Hihat Tune Also exchanged the eprom to the latest firmware (V4) with stable MIDI timing. Thanks to curetronic for the steady desoldering-hand:) www.discrete-audio-solutions.com www.curetronic.com http://colinfraser.com/tr909/909mods/909mods.htm
Oberheim Matrix 1000 EPROM chip, operating system version 1.16. The last official version released by Oberheim was 1.11; this version corrects some MIDI SysEx control issues that Oberheim overlooked, such as a really slow response to filter cutoff frequency settings. This replaces chip U804 on the main board (it is socketed, so no soldering is required). Took about 30min. – Bug fixes made by Nordcore. – MIDI NRPN parameters editing fix. – Faster processing of parameter changes that need a modulation matrix rebuild, there’s still a small lag but it’s…read more
