A True Rompler: Raw Digital Audio

YouTube via littlescale
"I wanted to make a device that plays back digital audio, without the use of any programming or a microcontroller or a computer. In other words, the most basic rompler, as a hardware-only device.

more info, schematics etc: http://little-scale.blogspot.com/2008..."

WMD Geiger Counter

YouTube via bigcitymusic
"This is the incredible sound smashing WMD Geiger Counter. We're just running a boring pitched kick drum into it. There are a massive amount of tones in this box. The hexa-decimal display on the top right tells you which wavetable you are using to digitally destroy your source. You can really obliterate whatever you put into this beast. We'll show you how you can control the sample rate redution via CV next video!"

NUSofting DaHornet Demonstration: This One Might Sting Ya!

YouTube via gearwire
"Can a NUSofting DaHornet software synth come close to the sound of the original EDP Wasp? That's what Bill Holland aims to find out in this demo while wearing a beard made of bees (off-screen).

According to Bill, it's not too far off, but watch this video and listen for yourself. There's been some buzz about this virtual synthesizer, but maybe that's just due to the bee fever sweeping the Gearwire office.

See more on Gearwire.com."

Doepfer A-192 CVM16 CV to MIDI with MaxMSP 5

YouTube via dkimcg. No audio in this one.
"simple test patch to read the CVs on the modular synth in the computer through MaxMSP 5. Can't wait to start using it in a Max patch!"

TipTop Z3000 modulated by PlanB Model15

YouTube via dkimcg
"See title.
I forgot most of what I was doing, but have a basic idea. See annotations for descriptions of what's going on.

New oscillator from Tip Top Audio, the Z3000. I think a dual camera setup would be better for videos like this, I'll try that next time.

Youtube's compression ripped apart the waves and made some of the sound messed up and sound like it's filtered or modulated or something. Try to ignore it. Maybe the stereo version sounds better."

DOEPFER A-188-2 TAPPED BBD DELAY

via this auction
"A-188-2 is another module that is based on a so-called Bucket Brigade Device (BBD). If you are not familiar with BBDs please refer to the A-188-1. There you can find some details about this special type of circuits.

The main difference between A-188-1 and A-188-2 is the type of BBD circuit that leads to completely different module principles and sounds. The A-188-1 uses different single BBD chips with one signal input and one signal output only. In contrast the A-188-2 uses as so-called tapped BBD that has available six outputs - the so-called taps after the BBD stages 396, 662, 1194, 1726, 2790 and 3328. In the A-188-2 we use this special BBD circuit (MN3011) to obtain these module features:

The module has available two separate mixing sub-units. For both mixers the levels and polarities of each BBD output can be adjusted to obtain two different mixtures of the BBD outputs. A new type of potentiometers with center detent and center terminal is used for the BBD mixing controls to have a better feel for the neutral position. Each mixer has a wet/dry control at its output that allows choosing between the pure input signal (original), the BBD mix or anything in between. The two outputs can be treated as stereo outputs but it is also possible to use one of the outputs for other applications (details in the next paragraph).

The A-188-2 has a feedback section available that is very similar to the one in the A-188-1. But as we now have 6 different BBD outputs available 6 different feedback types are possible. The feedback input socket is normalled to the "396" output (not to "1194" as shown in the scheme, the front panel is correct). But by patching the feedback socket to any of the single output sockets another BBD tap can be used for the feedback to obtain different sounds. Even external feedback processing is possible (e.g. with a VCA for voltage controlled feedback). The feedback control has polarizer function, i.e. the neutral position is at the center. Left from the center the feedback signal is subtracted from the input signal, right from the center it's added (negative/positive feedback). Even for this potentiometer the new version with center detent is used.
A special feedback can be obtained if one of the mix outputs is used for the feedback function. In this case for each tap the positive or negative feedback share can be adjusted. This leads to multiple peaks and/or notches in the frequency response of the module.

For each tap of the BBD a separate output socket is available. These sockets can be used for changing the feedback loop - as mentioned above -, for voltage controlled mixing of the taps - e.g. with the voltage controlled mixer A-135 or other applications that require access to each single tap.

The A-188-2 uses the same high speed VCO (HSVCO) for the BBD clock as the A-188-1. The clock and consequently the delay time can be controlled manually (delay control) and by the two control voltage inputs CV1 and CV2. The sensitivity of CV1 is approximately 1V/oct. CV2 is equipped with a polarizer (a new type of potentiometers with center detent). The HSVCO has a clock output available that is normalled to the clock input socket. These sockets can be used to link different BBD modules and to run them with the same clock. But even other applications with frequency dividers (e.g. A-163) or PLL (e.g. A-196) are conceivable. A voltage composed of the manual delay control, CV1 and CV2 is available at the CV out socket, e.g. to control an external clock suppression filter as the A-188-2 is not equipped with such a filter (same as for the A-188-1)." more info on the Doepfer website.
