optocoupler based dual ladder VCF - testing

Published on Oct 17, 2013 cirtcele·97 videos

"Listen with good headphones or speakers - lots of bottom end!
This circuit is still quite rough and I haven't settled on all the component values yet. It uses dual opto-coupler ICs - LED to transistor - to form two ladder VCFs. One is a diode ladder similar to the EMS design, the other is similar to the TB-303 transistor ladder, with many parts left off.
The diode ladder gets the audio input and the LEDs transfer the audio over to the transistor ladder, so both VCFs run in parallel but can be tweaked individually. The PCB version will have individual freq CV inputs and a 'both' CV input.
The outputs will be available separately plus a mixed output and possibly a difference output; only allowing the parts that are different between the two signals. It goes without saying the mixed output simply blows chunks!"

FS1a vs. e560

Published on Oct 17, 2013 Stephen Drake·39 videos

"This is a quick and dirty comparison of the Jurgen Haible FS1a frequency shifter and the Synthesis Technology e560 Deflector Shield frequency shifter. I've been asked a number of times to describe the differences/similarities between these two devices, and thought perhaps a quick video would provide some answers. The FS1a is an all analog device; the e560, all digital. Bruce Duncan of Modcan has said that this is one device that is better suited for a digital implementation, as while the analog version is really complex to design and build, and has numerous compromises, the digital version can be designed around the software code, which is quite easy to implement. However, the Jurgen Haible design is perhaps the best analog version of a frequency shifter yet, and I think it stands up well against its digital brother.

This demo isn't perfect - I didn't spend forever getting all the audio levels right, and matching the way the different effects worked, so you get what you get. I only basically demo three aspects of how one might use these devices. During the stereo panning demo, I may have the settings on the FS1a wrong.

This isn't really a fair comparison, as the Jurgen Haible FS1a isn't actually available as a commercial product, and even as a DIY project it's virtually unobtainium - Jurgen Haible passed away in 2011, and the pcbs for it aren't available currently, and may never be. The e560 is available in eurorack format currently, and sometimes in DIY format, which is how I've built mine behind a 5U panel."

Roland GR-700 PLUS 13 - Vintage Analog Guitar Synthesier w/ 13-pin Output, Memory Upgrade

Published on Oct 17, 2013

http://www.joness.com/gr300/GR-700.ht...

"The GR-700 PLUS 13 offers a significant upgrade over a standard vintage Roland GR-700:

First and foremost, this GR-700 has a custom printed circuit board installed to buffer the internal guitar synth signals, and provide a modern, 13-pin Roland synthesizer output. A vintage Roland guitar connected to this GR-700 will be able to access both the classic analog sounds from the GR-700, plus the latest in cutting edge Roland guitar synth tones, using the Roland GR-55 or VG-99.

The active circuitry is part of a DB25 input card, which frees the GR-700 user from searching for hard-to-fnd, expensive 24-pin cables. This GR-700 can use data-grade, shielded 25-pin cables which offer improved performance over the original Roland cable, at a fraction of the price.

To connect this GR-700 to a vintage Roland G-707 guitar, included is a matching DB25 output card for a Roland G-707 guitar. And more than just a 24-pin to 25-pin adapter, this card has a Roland G-202 poly distortion, hex fuzz circuit onboard. Unlike the G-202/303/505 or 808 guitars, the G-707 did not include hex fuzz. With this card, the G-707 has the same full range of capabilities as the other Roland guitars."
