Hollasynth Scanner - Low-Gain Electronics experiments

video upload by LowGainElectronics

"Just playing around confirming functionality of this Hollasynth Scanner pcb behind the Low-Gain Electronics panel. :)"

Details on the Hollasynth

"The Hollasynth four-channel scanning VCA is a version of Jurgen Haible’s Interpolating Scanner idea, in 4U Serge-compatible format, complete with a beautiful front panel by Loudest Warning

It is a four-channel voltage controlled crossfader. As the scan CV is swept from 0V to 5V, the mix output fades from channel 1, through a mix of channel 1 and 2, to channel 2, then fades to channel 3 and finally channel 4. In addition to the main mix output, there is an individual output for each channel. Front panel knobs provide an offset and attenuversion on the scan CV.

The gain of each channel is also individually controllable, so the module can be used as a four channel VCA as well. A switch allows the scanning control to be disabled so that only the VCA CV affects channel gain. Finally there are attenuator for the gain CV and initial gain knobs on the front panel.

What can I do with it?
Probably more than I can! But try some of these:

Crossfade between the wave shapes of a VCO for voltage-controlled morphing, e.g. from sine to saw to triangle to square and back. Like this.
Crossfade between up to four audio sources under voltage control. Like this.
Voltage controlled CV mixing. The inputs and outputs are DC coupled so you can use the module to mix and morph between CV sources
Voltage controlled signal switching. By appying stepped CV to the scan input, e.g. from a sequencer, you can switch between signals rather than fading… if you get the CV set up just right! Like this
Audio Waveshaping. Patch fixed voltages or LFOs or whatever you like into the signal inputs. Send an audio rate 0-5V sawtooth into the scan CV. Use the mix output as am audio signal. Like this. Or like this. (Thanks, Loudest Warning!)
How does it work?
The scanner contains four linear VCAs, one per channel, based on the LM13700 IC. Each VCA is controlled by the sum of two CVs: the direct VCA CV and the scanning CV. The scan CV is provided by a version Don Tillman’s beautiful scanner implementation, used with his kind permission. (But please don’t bug him if you have issues with the module!)"

Low-Gain Electronics - VCA / Comp module first tests.

video upload by LowGainElectronics

"Playing around with the new VCA/Comp. 95% bug free. Will require a quick pcb revision but overall happy with this performance. This patch is showing the triangle out of the LGE130 tri core vco into the -IN on the comparator with output of onside of the LGE114 Dual Slopes Compact. Acting as a triangle to square wave converter with PWM. Output of Comparator into VCA above being controlled by second half of Dual Slopes Compact. Nothing fancy. Just some fun / fat PWM rhythms!"

"Using the S/T&H module as a bit crusher to modulate a VCO’s frequency. Resulting in atari arcade machine sounds.

Dual Negative Slopes both in cycle mode. One providing a variable voltage source of which to be sampled. The second is simply clocking the S/T&H. Output of the S/T&H is being fed to the VCO Freq Modulation input. Audio is just direct from VCO’s output.

Music Thing Modular Graphic EQ DIY Build

Published on May 22, 2018 LowGainElectronics

"Real time build of the MusicThingModular Graphic EQ. I recommend this build for beginners. Fixed filter banks are very useful and highly underrated. Available at www.ModularAddict.com The photo at the end shows how I modified the module by drilling the jack holes out to allow the jacks plastic bushing to it in the panel a little. Less space between the pcb and panel. I also added 2 nylon flat washers to each of the screws on the sliders. This allowed me to properly tighten the screws for the middle pcb support. Not 100% necessary, but it makes me feel better knowing it’s secure. ^_^ Happy SynthDIY’ing!!"

New Low-Gain Electronics 2-Bits Binary Sequencer Module Overview Demo

Published on Feb 17, 2016 LowGainElectronics

"2 bit binary addressing digital to analogue converter. A four stage gate controlled preset voltage sequencer.

By using either the bit toggle switches, you can choose from manually turning On(up) or Off(center) each of the bits or switching to EXTernal(down) gate control.

The OR output is a logic OR gate based on the status of the two bit status. Each bit and OR output has an LED to indicate it's current status. The user can choose between Gate or Trigger for each Bit feed to the OR Output via the back of the module.

The CV output has a range switch to select between a 0-5V or 0-10V range of the stage pots.

8HP, +/-12Vdc @TBD mA
Retail: $199USD (available fall 2015)
