A Bibliography of Electronic Music from 1967

"This is a very rare book in Eletronic Music history. It was published by University of Toronto Press; this University was the home of Hugh LeCaine, Myron Schaeffer, and Gus Ciamaga - hugely significant pioneers of this music.

Myron and Gus were the first to hear/see Bob Moog's first synthesizer, and commissioned the first EVER Moog filter to be built. This book was begun about the same time, as a project to document the then-new world of Electronic Music. It has hardcover, clothbound, over 100 pages. It's dense but a great resource - for articles and records that existed at the time."

"The Controls:

The Geiger Counter may seem overwhelming, but once broken down, the controls are quite logical.

Gain:

Low settings provide clean tones with no distortion at all, while high settings will brickwall your signal for great sustain. Use the Gain control as a coarse setting for getting the desired tone from the selected wave table.

Tone:

The Geiger Counter's tone control blends muffled low-mids with chimey and clear upper mids and highs providing a very large range of sounds in junction with the Gain. All the way down and the sound is muffled and grungy with little upper harmonic content. The middle range is smooth and full bodied. The top range cuts the lows completely for only upper harmonic content. Use the Tone to fine tune the sound of the wave table.

Tone Enable/Disable:

This switch removes the tone control from the preamp circuit. The tone control sucks some volume from the gain, and this allows the pure ultra hot signal to go directly into the Wave Table. If a very clean tone is desired, set to Disable and adjust the gain to get the right amount of breakup. For most wave tables, disabling the Tone will produce completely different sounds by brickwalling to the extremes of the tables faster.

Direct In/Level:

The direct input allows a signal to be injected directly to the Geiger Counter's digital heart and bypassing the preamps coloration.

Sample Rate:

Controls the length of the samples your signal is converted into. Full up and the Geiger Counter samples faster than a CD. Dial it down a little and you'll lower the fidelity and frequency response, adding overtones and difference frequencies. Down a little produces some very nice chimey clean tones. Down more and higher notes disappear into difference frequencies, all the way down to 280Hz. The sample rate is sort of like a flange whammy.

When the LED is Red, the Sample Rate is in fine mode where the range is limited to the upper end.
The CV input and attenuator are only active when a cable is plugged into the CV jack. When CV controlled, the Sample Rate knob selects the center frequency about which the CV signal moves. When the LED is Green, the Sample Rate knob is logically ANDed with the CV signal, producing some interesting sounds as the CV changes.

Bit Depth:

This controls the finer details of the signal. All up and your signal is represented by the full 8 bits. Each step down cuts the resolution in half, adding quantization error distortion, all the way down to 1 bit making a nasty square wave from a once clean tone. This produces a lo-fi gated distortion sound.

The LED when Green engages Mask mode where your signal is logically ANDed to the 8 bit number produced by the Bit Depth knob. This produces uneven gaps in your signal for some interesting distortion sounds.

The Bit Depth CV and level control is only active when a cable is plugged into the Bit Depth CV input. The Bit Depth knob then controls the center frequency. However, unlike the Sample Rate control, the bit depth can wrap around the edges of the control if the CV signal is larger than the range allows for.

Wave Table:

This knob and display select the wave table to run your signal through. The wave table stage takes your signal and destroys it with math. This produces some incredible sounds. The wave tables are organized so that a more extreme version is typically found one up from the current one.

There are 252 wave tables in all, each with different harmonic content.

The display is in HEX, displaying the numbers 0-9 and the letters A-F. Don't be alarmed, it actually makes remembering your desired wave table easier! The wave table is remembered when the pedal is turned off.

The Wave Table CV input is similar to the Bit Depth's.

The CV signal is only active when a cable is plugged in.

The Wave Table will wrap around the end points 00 and FB.

The center is set by the WaveTable knob."

Raspberry Pi Synth Control Panel

via the Raspberry Pi blog "This is before the 'silk screen' is applied (i.e. a couple of Photoshop steps before it goes into OpenGL). The whole 'wiggly line diagram' concept is being binned for a much more preset-driven style, and lots and lots of LEDs. This redesign will let the modulation be computed much faster, and should buy me back around 20% of the CPU, which will be a big defense against audio breakup when I push the latency down hard..."

via the Beat707.com forum

"I thought I would pass along some photos of my completed Beat707 in it's Front Panel Express paneled Hammond case. And a HUGE thanks to Altitude for providing me with the FPE panel files. The only FPE panel file he did not provide was the side plate with the Midi ports. I had this custom made by FPE."
