The Multi-Plexer will produce those famous sounds that you grew up hearing on Lost and Space, The Forbidden Planet, Star Trek and other Sci-Fi classics. The name was assigned, simply because that’s what it does. The circuit sends an analog signal around in a circle, bending and distorting it, like a ring modulator. However, the MP is a FREE RUNNING Synth. No input is required for it to operate. But if you input a signal (like your guitar) it will ride the MP self generated wave. The end product is a result of many manipulations. I cannot describe its sounds in words. Please listen to the links and judge for yourself.

Circuit:
The circuit is a basic pure Analog Synth (not noisy digital) with Depth, Sustain, Impact, Rate, Frequency and Volume adjustments. Only TOP Quality components were utilized. “Spared no expense” The circuit board was custom manufactured using a photo-etch system. It runs on 2- 9vdc batteries (included). Totally isolated circuit will not produce hum or ground loops on your Guitar amp or stereo as other plug in the wall synths do. This is a great gadget to add to your rock band as a creepy, self running, sound generator. It’s also a lot of fun to just play with on your home stereo. This device runs at a low frequency, therefore, it responds well to Bass guitars and keyboard inputs. It's initial design was intended for generation of neat sound effects. The input jack came later.

Check out the MP3 files that my friend in OK sent me (see links above). The original circuit was developed in the 1970’s. 30 of them have sold on the ebay so far. See my feedback for great comments on this device. This gadget is not available anywhere besides D-Lab. In other words, you will be getting a very unique item. My investment per unit is $70.00 (parts), excluding numerous hours of layout and construction time. The cost have elevated due to the cosmetic upgrades. I am doing my best to provide a top notch product. I realize that my gadget is small league compared to the big hitters (Moog, Paia & Korg). I just hope that you enjoy it. Bands around the country have been e-mailing me with great reports incorporating the Multi-Plexer's weird sound into their gigs. This device is great for Band Background weird noise or making your instrument act crazy!

This device is intended for fun or interface with your band equipment, not for development of a new Outer Limits episode. The cost is much less than store bought models and it is fully portable, unlike anything else on the market. Please e-mail me with questions or concerns before bidding. Unit comes with a nifty overview sheet for operating this crazy instrument."

Vember Audio Short Circuit Free Sampler

"Sampling is supposed to be fun

Prior to shortcircuit it wasn't as fun as it could be.

Shortcircuit was created as a reaction against the ongoing trend where software samplers are being designed with the primary intent of library playback. It is intended for people who, like us, consider a sampler to be a musical instrument in its own right, and not just a way to emulate other instruments. It has been a very high priority to make sure that adding and editing individual samples is as fast and logical as possible.

The sample hierarchy in shortcircuit allow you to place samples directly at the highest level of the multi, without having to deal with instrument hierarchies and patches. Want to add a sample to your song? Just drag & drop the sample into shortcircuit and you're ready to go. Samples can be put in groups for multi-sampling and kit-building, but the complexity is only there when you need it.
let your ears be the judge

Sound quality is of highest concern, and shortcircuit uses very high-quality interpolation to ensure that your samples sound as good as the source material, regardless of the pitch you play them at. All filters & effects are calculated at the precision required for them to sound the way intended and oversampling are used when required to prevent aliasing.

Shortcircuit was designed to sound great, all other concerns have been secondary. But don't take our word for it, download 'shortcircuit free' and find out for yourself.
...and the toys, don't forget the toys!

Each voice in shortcircuit features two filter-slots, and the selection isn't limited to the traditional pick. In addition to the regular lowpass/highpass/bandpass/notch & peak-filters and variations thereof there is an array of filter algorithms (not strictly filters in the traditional sense, but called so because of their location in the audio path) including distortion, parametric/graphic/morphing equalizers,bit-reduction/decimation, gating, limiting, slew-rate distortion, ring-modulation, frequency shifting and phase-modulation (better known as FM). The selection even includes analog-style oscillators that you can mix with the sample."

NuDSP Mod271

" Mod271 pronounced as "Mode" (the 271 being a play on Euler's constant) is really a DSP playground with unified audio/MIDI support and functionally is supposed to exist somewhere in between Reaktor, reacTable and Reason (although this isn't the case quite yet). I will refer to Mod271 as M271 throughout the documentation.

This all started out as my own personal frustration with clumsy knobs and sliders in current use by most audio software. I wanted to have an intuitive interface with variable resolution control built-in. The entire interface is rendered in 3D, so you can zoom in and out with the mouse wheel. Zooming in on a node will give you more precise control over its position, zooming out does the opposite.

Really I wanted an environment where there is no different between MIDI or audio signals, so an audio effect will work the same with a MIDI signal. Also I wanted an integrated way to handle envelopes, something that has a direct and visual connection with a node, this ended up meaning the removal of the GUI all together, there is only one interface for everything :) PCs are fast enough now to make this happen.

I'd like M271 to end up as a total modular environment where you can easily make performances just as easy as a synthesizer or effect.

Some cool features include:

* ASIO/MIDI support
* built with portability in mind, a mac/linux version shouldn't be terribly difficult.
* everything is a full audio-rate signal which means you can do DSP type stuff to say a MIDI stream.
* there is a VSTi version in the works but it is still pretty unusable in a general case.
* every node can be automated with unlimited control points and automation takes place right in the 3D environment.
* nodes can influence any amount of other nodes or switched into a singular state.
* all signals are drawn at audio rate and with full hardware acceleration, although this can be disabled.
* the entire environment is rendered in 3D.
* radial and linear influence modes are supported for every node.
* all envelopes and motion are completely sample accurate, meaning you can make an oscillator out of an envelope.
* over 25 node types, of course this is going to grow.
* Python node type that will allow easy extensions.
* and most importantly it's fun! "
