In this video I do a more in-depth demo with my Jupiter-6 VCF multi-mode filter clone eurorack module. It's a very colorful filter that gets more interesting with more complex signals you feed into it. It also has an aggressive nature that comes out when the inputs are overdriven.
Two different oscillators can then be mixed together. A sawtooth oscillator is used, a square/PWM wave is used. Different filter modes can be selected: 4-pole lowpass, 2-pole bandpass, 4-pole highpass. Also, two different control voltage modulations can be mixed together to change the frequency. I run a decay envelope from the Bastl Skis along with a triangle LFO, then I use Sample-and-hold. The oscillators are coming from my Pittsburgh Modular Synthesizer Box. Recorded direct to Tascam DR-05 from my Mackie mixer, no effects, no normalization. Beware some low and high frequencies, so watch your levels while listening to the demo.

In my previous post I replaced the battery in my Oberheim Matrix-12 synthesizer, which completely randomized my patch data for very interesting results. Now you can dump this SYSEX file into your own synth for random patch mayhem. This will over-write your entire patch bank! So be sure to back up your own patches safely to computer first! I have a link to my download page on the sidebar to the right side of this page "Featured Post" :) If it's not there, enter 'download links' in the search bar above to get to my download page. I can't possibly manage dozens of links to the page.

I replaced the memory backup battery today. Before restoring my patches, I took a little tour of the corrupted/random patch data. Behold the glorious analog synthesizer dark noise madness. I'm talking full-on freakout mode. Take note of the corrupted patch names - reminds me of some weird alien dialect. In case you're wondering there is nothing wrong with my synth, it's working better than ever before. Recorded direct to Tascam DR-5, only normalization applied to some quiet parts.
What I also discovered is the battery is responsible for holding variable system data like osc and filter auto-tuning data. Before, I was experiencing the 'voice processor 1 malfunction' messages, system lock-ups, and system not booting properly. After the battery replacement, the synth has operated 100% correctly w/ no issues.

In this quick video I show how to make the Korg MS-20 synthesizer achieve the weird theremin-like, sci-fi, singing as heard on the Goldfrapp Felt Mountain album. This classic sound is so very renowned for the MS-20.
Alison would send her mic into the External Signal Processor. This sends pitch and gate control voltages to control the synth. We don't actually need to do that. As the sound is coming from the synth engine, we can simply use the keyboard to control it.
