Doepfer A-101-1 vactrol multitype filter

"this is the first vactrol based module in the a-100 system. a vactrol is a combination of a light depending resistor (ldr) and a led (light emitting diode) both put into a small light-proof case. increasing the led brightness causes a decrease of the ldr resistance (e.g. the light controlled voltage module a-179 is an application of a ldr). this effect can be used in circuits that require variable resistors to obtain the desired function (e.g. vcfs, vcas, vc phasers, vc trigger delays, vc slew limiters, vc envelope generators, vc lfos, vcos and many more). the advantage of vactrols compared with other solutions (e.g. otas, diodes, transistors or fets as variable resistors) is that they behave like a normal ohm resistor and can handle high voltages without causing distortion. this is probably the reason why the sound of vactrol-based circuits usually is described as soft or mellow. disadvantages are the expenditure and consequently the expenses and the not exactly defined coherence between led current and ldr resistance. for each vactrol the ldr resistance decreases when the led current increases but mechanical and electrical tolerances cause that each vactrol will behave a bit different (e.g. because of the differences in alignement and distance between led and ldr, different brightness of the leds at the same current).

module a-101-1 is a special multitype filter based on an idea by nyle a. steiner (published in electronic design, issue 25, december 1974, page 96 ff). the circuit uses the standard non-inverting amplifier filter design. different filter types (low pass / lp, band pass / bp, high pass / hp) are realized by injecting the audio signal into different points of the circuit and using a common output for all filter types. one may feed three different audio signals into the filter simultaneously. each signal is filtered correspondingly (lp resp. bp resp. hp) and the sum of the three filtered signals appears at the output. of course it is possible to feed the same signal to all three inputs. in this case one obtains different combinations of lp/bp/hp according to the settings of the three input attenuators for lp/bp/hp. even a notch filter is possible (not available in the original design). the filter inputs are normalled, i.e. the bp input is connected to the lp jack socket provided that no cable is plugged into the bp socket (same applies for hp/bp inputs).

in contrast to the original circuit vactrols are used instead of diodes as variable resistors for frequency control of the filter. due to the "crooked" response of vactrols the filter has not an exact frequency control standard (like v/oct). the inevitable tolerances between different vactrols will lead to an individual sound of each module and individual resonance behaviour. even the resonance control is realized with vactrols. consequently this parameter is voltage controlled, too. resonance can be increased up to self-oscillation. resonance and consequently self-oscillation may vary with the filter frequency because of vactrol tolerances.

Doepfer A-127 Voltage Controlled resonance filter

"module a-127 is a triple resonance filter unit. it contains three separate voltage controlled band pass filters. each filter has it's own lfo (triangle waveform) with led display and adjustable frequency and amplitude. instead of the internal lfo an external control voltage may be used to control the filter frequency. in this case the external voltage is fed into the external cv jack (with integrated switch to turn off the lfo signal) and the amplitude control of the lfo affects the level of the external cv signal. each filter is equipped with the following controls: lfo frequency, lfo/external cv amplitude, filter frequency, filter resonance and filter amplitude. in addition to the mix output for all three filters each filter has a separate audio output. the original audio signal can be added to the triple filter mix signal with a separate control. all of the 3 filters share a common audio input with attenuator. the filter audio inputs are very sensitive so that distortion may intentionally be used to create new sounds - if desired.

the frequency control range of the bandpass filters is about 40hz...6khz, the frequency range of the lfo's is about 0.02hz...20hz (= 1 min ... 1/20 sec per cycle).

each of the three filters can used also as a 12db low pass (with resonance control) instead of band pass. for this a jumper has to be changed on the filter board in question. in this case the module can be called no longer "resonance filter" but "triple low pass filter". it is also possible to modify only one or two of the filters to low pass.

this module has a maximum current draw of 100ma. it requires 28 te/hp worth of space to fit in a eurorack frame."

VINTAGE Synare Lo-Tom Electronic Space Drum Oscillator

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"Up for sale we have an ORIGINAL Synare Lo-Tom. These were some of the coolest and rarest electronic drums ever made. An absolute must-have for the dub enthusiast! Pure analog floor tom/hand drum/djembe sounds with plenty of features; sounds great run through delay as well.

Drum works perfectly; lots of sounds and tuning "drift" can be coaxed with the RUN setting. Very good cosmetic condition for its age; some wear on head as to be expected."

"Up for sale we have an ORIGINAL Synare Sensor. These were some of the coolest synth/noise making devices ever created. Tapping on the chassis and fiddling with the knobs is quite an experience.

This particular example was just serviced with an original OEM Synare sensor and capacitor. Works and sounds phenomenal. A small chip is present on outer casing by epoxy (these were supposed to be mounted to a snare, so its bound to happen). Please see pictures for more details."

First look at iPad app Deregulator - using Thumbjam

Published on Jun 9, 2014 phillwilson·178 videos

"This is my first go on deregulator the new iPad app by Ashshaosh Daa. The app is a delay/echo/reverb combo but with a twist...all components can be randomized to alter each/any setting over time.

the concept is very simple but in use it is a great way of creating mangled textures that recycle what you put in and spitit back out at you in new in interesting ways."

iTunes: deregulator - Savelii Kaliupanov | ThumbJam - Sonosaurus LLC

"Deregulator it’s a mini-processor of stereo effects with Echo, Delay and Reverberator. Input signal goes to echo and delay simultaneously. Then delayed and echoed signal lands into reverberator. All parameters of this effects may be randomised at once and some key parameters can be randomised dynamically all time. On output we have wide effects range from simple mono echo/delay/reverb and combinations to near granulation live when remains of sounds create nebula around original input and like morning mist its blurring and smudging sound into scape of something new, vibrant and beautiful (degree of beautifulness depends on what you feed in D).
Delay just repeat sound pieces and size of every piece can be randomised, this chop and remix original sound into sometimes very glitchy, something new. Echo behaves like a usual echo unless you start randomising delay and feedback parameters. Reverb have three parameters, room size, damping and wetness of output. Off course all of them are randomisible. Randomising its a root of conception in this little app.
How it sounds like? Lets walk together to the border that splits effects from synthesisers where only granular with live input lives and question this line, she is exist? You must play with it or go to soundcloud(tag deregulator) for examples.

Go to look at instruction and detailed description on ckek.ru

Feature list:
+ Three linked effect module (Echo, Delay and Reverb)
+ Randomisers for every parameters of this effects
+ Ability to randomise all parameters at once
+ Recording of affected audio to wav
+ Share files to iTunes, AudioCopy 2, AudioShare
+ Audiobus of course
+ 25 non-factory presets slots
+ Stereo/mono

Coming soon:
+ Universal app(Yeah, download once and run everywhere)
+ Audiobus 2 and all slots
+ IAA

Tested on iPhone 4s(iOS 6&7), iPhone 5, iPhone 5s, iPad 2, iPad New and iPod touch 4. And i don’t recommend run this app on something lower then 4s. On iPod4 lag is too big, Deregulator need ~100mb ram and more power in heart. iPhone 4s/iPod5 is recommended as low line to work comfortably.

Have fun and make some noise %)"
