Cwejman CTG-VC Complex Transient Generator

samples at Analogue Haven

"the envelope generator provide control voltages that can be used for dynamic change of all voltage controlled parameters, such as; frequency, amplitude, pulse width, cutoff. the most common use is controlling filters cutoff frequency and a voltage controlled amplifiers amplitude in order to achieve dynamic timbre- and level-changes. all parameters such as attack time, attack hold time, decay time, sustain level, release time and output level are voltage controlled.

the ctg-vc is a complex transient generator with a lot of features, such as; two different shapes for the attack, attack hold (a-hold) for more punchier sound than a standard attack, variable decay slope (d-slope) from natural exponential to heavy logarithmic, attack-decay loop (a-d loop) and polarized level for outgoing transient signals which means that both outputs levels are controllable in both directions (positive and negative). a-d loop switch activates, when on, a steady state attack/dacay generator and the rate is determinated by attack/decay time and attack/decay modes. the external signal alone in to the a-d restart input start a single a-d transient for every new external signals a-d restart period (every shape). the sustain level should be in pos. 0. zero restart resets (when on) the remaining release voltage for new gate signal so attack starts always from 0."

Cwejman MMF-6 - multi output filter

samples at Analogue Haven

"the mmf-6 is a multi mode filter with six outputs, first three from the left; "clean" low pass, band pass and high pass. low- band- and high pass to the right are processed by three separate (for every output) saturation circuits with two modes; soft and hard.additionally, the filter core has so called "symmetry" control for the resonance and cutoff frequency. it is possible to control cutoff so positive and negative going signals has different cutoff frequencies, from a subtle "edge" to very dramatical character of the audio signal (including frequency division effect). now it's possible to imitate the famous moog filter (it can not replace it, of course), ota based filters and others. all this by modulating symmetry by one of outputs (pre-patched to "clean" low pass output) or an external signal. now it is possible to mix clean and saturated audio signals in any combination."

Cwejman BLD - Bass-Lead & Drum Generator

samples at Analogue Haven

"the bld has all components and functions necessary for generating bass lead and drum sounds with focus on bass drum sounds. it can be trigged by a push button or by an external signal (any shape). the pitch, cutoff frequency, transient times and amplitude are also voltage controllable by external signals. the bld contain main sound generator (oscillator) and noise generator and modifiers such as low pass filter, amplifier and two transient (contour) generators.

oscillator has two manual pitch controllers (fine, coarse) and two inputs for controlling the pitch by external signals (fm1, levelled, bipolar pre-patched to transient generator ar and fm2, calibrated to 1 volt/octave). waveforms and mix between shapes is controlled manually from triangle, mix between triangle and pulse, pulse, mix between pulse and saw tooth and saw tooth). oscillator level is controlled manually from 0 thru nominal signal strength to saturated (curved, for more punch). pulse width is controlled manually and by an external signal (pwm).

low pass filter has two audio inputs marked oscillator level and noise level, the cutoff frequency is controlled manually, transient generators ar and ahr and by cutoff pre-patched to fm2 cv input.

noise generator is connected to the low pass filter and to the amplifier (noise level). the noise generator can be routed in to the amplifier (pre) or directly to the output amp (post). the noise generators level is also controlled by pre-patched ar generator thru input noise level.

ar and ahr transient generators are activated manually by the push button trig and/or by an external signal (input trig). attack, hold and release are manually controlled and by an external signals connected to inputs a1, r1 (ar) and a1, hold and r2 (ahr). amplifiers gain is controlled by mix of ar and ahr and by an external signal connected to the input velocity."

Tuvan Throat Singing & Theremin


YouTube via copperleaves

"Here is a short improv for Tuvan/Mongolian throat singing (a style known as "khoomei") and MIDI theremin. The instrument you see me holding in the video is called a "morin xuur" or "horse fiddle". It is normally played with a bow but in this composition I pluck the strings and also drum my fingers on it to play rhythmic patterns. I'm afraid I'm not a particularly good throat singer, but I do enjoy doing it a lot and I greatly admire the Tuvan and Mongolian musicians who are the real masters of it.

The MIDI theremin you see in this video is the Moog MIDI Ethervox."

Optigan Demo - Swing It!


YouTube via peahix

"OK, this is especially for all the folks out there who refuse to believe that the music in the car commercial was, in fact, made using either an Optigan or samples of an Optigan. In this video I use a not-very-well-working and very dusty Optigan (I buy authentic 70s-era dust on eBay to sprinkle on all my Optigans) to show how this music was created. Whoever put together the music for the commercial almost certainly used samples of the Optigan (a comprehensive set of which is available from my website: http://www.optigan.com), but the result is more or less the same as if they'd played it on a real Optigan drenched in reverb.

Incidentally, you can hear Optigan sounds in LOTS of TV commercials- it's just that they're usually mixed in with other instruments as a texture, rather than played solo as is the case here. There were 40 different musical style discs made for the Optigan, so it doesn't just sound like a big band. Most of the folks who've bought my sample set are commercial and/or pop music producers, and I've stopped keeping track of all the commercials and songs that feature Optigan sounds.

Oh, and back in the year 2000, my band Optiganally Yours used the "Swing It" disc to record a song called "Walk & Chew Gum" for the Powerpuff Girls: http://www.youtube.com/watch?v=Pc-jxj...



To sum up: the music in the commercial is not a "song" from ANY old record. It is a series of one-bar big band riffs (arranged by Art DePew in the style of Tommy Dorsey) strung together either manually on an Optigan, or by assembling a set of Optigan loops on a computer.

MFOS Oscillator Calibration Part I


YouTube via theraywilsonshow
"This series of three videos shows you that after you hand match your transistors they can give you totally acceptable performance. I demonstrate the use a of a hand matched NPN pair in one my MFOS oscillators. This is Part I of the MFOS Oscillator Calibration video series. There are also a Part II and a Part III video."
