"It was last worked on by Three Wave Music in NJ in 2010. It runs super smooth. The sliders are all good some are tough but all move fine. The Keyboard works great, some keys are a little stickier than others."

Arcade Sounds with the Moots (DFAM, Mother-32 & Freqbox)

Published on Aug 30, 2018 HardtekStudios

"Moog! Please don't take our Moogerfoogers away!
This jam I am getting some hard & nasty classic arcade sounds by routing the Moog Mother-32 thru the Moogerfooger Freqbox. The Moog DFAM is providing a sides scrolling drum sequence for the arcade sounds to crackle against. Lots of patches cables run between the M-32 & DFAM and the M-32 is using it's Envelope and LFO to further modulate the Freqbox! If you like what the Freqbox is doing here, then snatch one up as soon as you can, because Moog Music and announced the discontinuation of the entire Moogerfooger line."

New Noiro-ze VCF & VCA Eurorack Module from nonlinearcircuits

Published on Aug 30, 2018 cirtcele

via nonlinearcircuits

"This module uses the same blackbox technique as the Shat-noir Phaser.
The VCF is based on the Steiner diode VCF but this one uses LDRs rather than diodes and a CV control system to suit. The nice thing about this filter is you can feed different signals to the LP, BP & HP inputs then surf between them with your CV, quite different from regular filters.
The VCA is really there to use up a spare op amp and is based on the Korg PS3100 VCA, works very well for what it is.

PCB set = USD24
Panel = USD22
assembled = USD210"

AJH Synth V Shape (wave twisting, distorting and folding)

Published on Aug 30, 2018 DivKidVideo

"Here's the new AJH Synth V Shape. A wave twist and distortion unit. It offers skewing/PWM-like sounds that almost get to rectification and folding like tones up top and then underneath we get a soft or hard clipping distortion with an added soft wave folder. The device is on the slightly softer side which keeps it very musical without getting too harsh in it's shaping or distortion. Couple it with the Wave Swarm or Ring SM and there's a tonne of potential shaping from the AJH range.

TIMING INDEX / SECTIONS

00:00 Welcome, hello, patch previews "what's to come"

01:05 Features, wave twisting, PWM-like FX, distortion, soft/hard clipping and wave folding run down along with the routing options.

02:39 Shape/Twist sound demo - triangle waves (with and without modulation)

03:52 Shape/Twist sound demo - saw waves (with and without modulation)

04:16 Distortion/Folder demo - triangle wave and soft clipping "come make sine waves!"

04:40 Distortion/Folder demo - triangle wave and hard clipping

04:54 Shaper into the Distortion

05:30 Distortion/Folder demo - wave folding with Batman ears. Looking at both soft and hard clipping stages as part of the folding.

06:00 Modulation the distortion/fold and doing so up to audio rates.

06:48 Creating a weird shaping VCA. This uses the distortion section like a VCA and using envelopes we can get some quirky VCA like functionality. The shaper is used to make PWM-like FX.

09:43 Using the V Shape to twist, fold and distort LFO signals.

11:57 Shaping envelope CV signals

13:17 A distortion like FX device for processing drums. Drive, glitch and fuzziness comes out :)

14:58 A new piece of music to release from this thing! Using both processors in the unit as a parallel processing unit to create dual layers to spread around a patch.

17:32 Using the V Shape to twist and distort already moving/morphing waves. I use a lo-fi morphing wavetable at the input for even further modulation and animation.

19:14 Dual channel functionality. Using one side of this for bass sound and the other for a melodic lead line."

Yamaha QX5 Digital Sequence Recorder (MIDI Sequencer) LCD repair

Published on Aug 30, 2018 Sbranvlztronics

"An old Yamaha QX5 sequencer that was collecting dust for decades, and needed some repair (the LCD was fading). It was cleaned, fixed, and is working. I had only a blue LCD, so now it has a new look.
The soundtrack is the Arduino Clock Divider Logic thing, Arduino CV Quantizer, 3 VCOs, 3 VCFs, 3 VCAs, 3 ADSRs and 2 LFOs (analog modules from Matrix II analog synth and MSB Modular Synth B), everything built here at the 'Sbranvlztronics Labs' :) (watch the other videos in this channel in case you have interest in analog synthesizer modules).
Thanks for watching."
