Concert of Containment, Sunday 12 April 2020, 16h

Published on Apr 13, 2020 RADIOKLOW

"This concert was given in a virtual room for an audience of Friends and Intimates, during the present containment against the covid 19 pandemic.

I wanted to gather some close Friends and Intimates for a moment of music performed on my favorite synthesiser and tibetan bowls, to share warmth and fraternity. Beyond this small group of persons, these improvisations are offered to everyone in this world, with the hope to bring all women and men peace and serenity. They are a travel to light.
A the beginning of them, I chant a mantra for healing : "Om Shree Dhanvantree Nahma".

With all my love and compassion for everyone

I dedicate this concert to my dear cousin Jean-Luc who has suffered from the bad virus and went to hospital but has now fully recovered. I will soon come back home and share again life with his wife !"

PAIA 4700 Modular Synth

via this auction

"Vintage PAiA 4700 modular synth. As far as I can tell, these were DIY modular synths first released in 1981. These are somewhat quirky machines, and can produce some really interesting and creative sounds. Note that these use the hz/v CV standard (notably used on the Korg MS-20) rather than the modern v/octave standard. The two-part telex case conveniently closes up for easy transportation.

This unit comes with the following modules:

4710 - Balanced Modulator (x2)
4711 - 4/2 Mixer (x1)
4712 - Spring Reverb (x1)
4720 - VCO (x3)
4730 - VCF (x1)
4740 - Envelope Generator (x2)
4761 - Wing (x1)
4770 - Watt Block (x3)

FLAME Midi Talking Synthesizer w/ Joysticks

via this auction

"Includes original box, 2 original manuals and 4 different ac adapters for different types of worldwide voltage...

"The FLAME MIDI TALKING SYNTH is a small-sized MIDI-controlled sound module based on the analogue Speakjet ™ chip, produced by the U.S. company Magnevation LLC. Originally designed for basic artificially generated speech output in American English tongue it was then refined and further developed as an 8-bit sound module with speech-like sounds and synthetic robot voices as well as beeps, alarms, noise and retro-style sci-fi sounds. Due to the structure of the Speakjet ™ (with its complex sound synthesizer, preset sounds and serial interface) it offers an impressive range of possibilities. It contains 72 speech elements (allophones), 43 sound effects, and 12 DTM touch tones. The idea was to create sounds, patterns and sequences in the 8-bit style of the 80s or other retro sounds for making music instead of just simulating speech. Most allophones can be tuned and used tonally. The FLAME MIDI TALKING SYNTH contains two Speakjet ™ chips to produce a richer and more complex tonal variety as well as generating a pseudo stereo effect.

Since the Speakjet ™ has not originally been laid out for the purpose of making music it is actually not fully controllable via MIDI input, i.e.: once sounds are triggered they cannot be directly stopped by Note Off messages from a MIDI keyboard or a sequencer. Thus a MIDI-controlled audio tremolo has been implemented in the FLAME MIDI TALKING SYNTH virtually allowing MIDI control and enabling an easier integration into a MIDI setup. The FLAME MIDI TALKING SYNTH lets you play back preset words in its EXPANDER mode via an external MIDI keyboard or a sequencer. In addition you can use the FLAME MIDI TALKING SYNTH as a stand-alone MIDI controller since all controls and joysticks send MIDI control/change data to the MIDI-OUT connector.

The internal sound is generated by the two independently controlled Speakjet ™ chips. Each of them provides a mono audio output (32 kHz PWM output) through a 6.3 mm stereo socket. The right audio channel is assigned to chip A, the left channel to chip B. An insert Y cable splits both channels into two mono audio outputs, allowing you to position the channels individually within the stereo sound field with any external mixing device. The sound level ratio of both chips can be adjusted with the MIX control. An equal sound level is obtained by turning the MIX control to the cente5r position. All functions are clearly visible on the front panel with the start/ stop /MIDI-sync/ tempo functions on the upper right-hand corner, sound/ tremolo/ scale/ note/ pitch and random functions in the middle. The HOLD-switches are used to freeze the position of the joysticks. The REC-switches are used to play back the recorded movements of the joysticks. You can switch between the modes SEQUENCER (SEQ) and EXPANDER (EXP) with the switch in the middle of the panel."

Sequential Artist Spotlight Interview with PHIL KOPSAFTIS

You can find the interview on Sequential's website here.

"When he’s not busy outside the music world as a caretaker of an historical site, Phil Kopsaftis is likely creating sound and music for the indie film and game world or documenting unique and creative synth tips and tricks on his YouTube Channel. He likes to share and employ techniques and approaches that aren’t always obvious on the surface, and ends up frequently crossing into less-traveled musical territory. His hope is to ignite that same sense of adventure and exploration in other synth owners and inspire them to take their instruments to new musical and sonic areas.

We chatted with Phil on how he’s using the Prophet-6 in his music."

Staying Inspired During Isolation - Novation w/ Danielle ‘Danz’ Johnson

You'll find the full article on Novation here.

"A bit about myself: I make music under the moniker of Computer Magic. I’ve been making music for roughly ten years now. I had no idea I could even write a song until I sat down and tried. I taught myself how to write music by ear and produce it by watching YouTube videos. Eventually, I got signed to a label in Japan. In the states I started a record label to release my music called Channel 9 Records. For Channel 9, I design my artwork and merchandise, order stock from pressing plants and find physical and digital distributors for the records. I was able to funnel money into the record label by licensing my songs which, luckily enough, I own all the rights to, being the sole songwriter, arranger, engineer and producer."

Gotharman’s New SpazeDrum Now Available for Pre-Order

Gotharman’s New SpazeDrum featured in previous posts here, is now available for order.

Details via Gotharman's website here.

"Voice Structure

It has 4 analog voices, that each has 4 parts - 16 parts in total. With the 4 parts of each analog voice, it is possible to program 4 variations of the same sound, or even 4 completely different sounds, that will cut each other off, when playing them back.

The Drum Oscillator of each part can be set up to one of four configurations, at a time:

Analog Percussion - A dual analog percussion oscillator and a digital oscillator. The analog percussion oscillator has special parameters like Shape, Buzz and G-Ray feedback. The digital oscillator can run in several modes, like waveform, resonator, percussion oscillator, cymbal oscillator, clap oscillator and sampler. Each oscillator can have most parameters modulated by any modulation source. The analog percussion oscillator can be FM'ed by a percussion noise source and by the digital oscillator. Can produce kicks, snares, analog hihats, toms, claps, noise and much more...

Analog Cymbal - A dual analog percussion oscillator and a digital oscillator. The analog cymbal oscillator has special parameters like Shape, Buzz and G-Ray feedback. The digital oscillator can run in several modes, like waveform, resonator, percussion oscillator, cymbal oscillator, clap oscillator and sampler. Each oscillator can have most parameters modulated by any modulation source. The analog Cymbal oscillator can be FM'ed by a multiple square wave source and by the digital oscillator. Can produce metallic sounds like cymbals and hihats, noises and much more...

Analog Clap - A dual analog percussion oscillator and a digital oscillator. The analog clap oscillator has special parameters like Shape and G-Ray feedback. The digital oscillator can run in several modes, like waveform, resonator, percussion oscillator, cymbal oscillator, clap oscillator and sampler. Each oscillator can have most parameters modulated by any modulation source. The analog Clap oscillator can be modulated by a clap oscillator, to produce the classical clap sound, and it can be FM'ed by a noise source and by the digital oscillator. Can produce hand claps, noises and more...

Will From Humble Audio Explains Their Quad Operator Eurorack FM Module

Published on Apr 13, 2020 Perfect Circuit

"Will Stockwell from Humble Audio came by to give us some background on what inspired the Quad Operator and to show us some of its sound design capabilities. The Quad Operator approaches FM without the constraints of modulation algorithms and lets you freely modulate any of the four operators with another operator or itself. Each of the four operators have variable waveshape and produce all of the traditional analog waveforms. They can also be locked in phase together like a digital FM synth or used in free running mode.

The Quad Operator has a knob per function control layout which is uncommon for FM synths and allows quick changes to the sound. At 8:42 Will goes over the control layout for the four operators and modulation matrix mixer as well as the Algo expander which allows you to store modulation presets and crossfade between them.

AI007 DIY Quad VCA Eurorack Module Build Guide

Published on Apr 13, 2020 AI Synthesis

via AI Synthesis

"Portland, OR, USA April 10, 2020 –

AI Synthesis has released the AI007 Quad VCA/Mixer in both a built and guaranteed version, as well as in kit and PCB/Panel format. The AI007 Quad VCA Mixer is a compact, high quality, and flexible way to control voltage (audio or cv) in your modular system). Each of the four inputs are DC coupled, allowing the amplitude of CV signals as well as audio rate signals to be voltage controlled. The outputs are also normalled together into a mixer, allowing the AI007 Eurorack Quad VCA Mixer to be used as a voltage controlled mixer. Once a cable is patched into a VCA output that output is removed from the mixer signal, allowing each channel to be used independently, giving users four VCAs in total. A dedicated knob shapes the curve response from Linear to Exponential.

Following the tradition of the other eurorack modules, the AI001 Multiple,AI002 Mixer, and AI003 Looping ADSR, the module has a full video how-to build guide. Unlike some DIY companies that focus solely on providing kits, AI Synthesis has an educational mission and our kits and documentation are aimed at those who have never held a soldering iron. PCBS are professionally manufactured, and all panels are aluminum."

Ukuthula by YLEM

This one is in via YLEM who had the following to say about the piece:

"I recently realized a work that to me is quite evocative.
It is called UKUTHULA that in zulu language means 'silence'.
The work is quite long and abstract but I think it could inspirational.
I realized the piece with Reason11 and all you hear is made exclusively with noise generators, LFOs, filters and effects.
There are no sample.
The only exception is of course the final part.

Shows cosmetic wear, but overall in good shape. (The last image is a digital advert for informational purposes).

The unit appears to work well with the following exceptions — the light in the ‘start' / 'tap' does not light up, but the button works well; the ‘set sec’ button does light up, but the button does not work (may just need a good cleaning); the two smaller rubber feet on the bottom are old / feel sticky; unit is missing 1 rubber foot which has been replaced with felt foot. Unit is older, used, and sold as-is.

Includes power cable. (and yes, has the plastic battery holder inside with two healthy AAs included).

Rusty sounds for a rusty synth. Cool cat.

via this auction

"Octave Kitten monophonic analog synthesizer in fair condition with some rust on the front panel. This unit is mostly working except for a few minor functional issues, please read full description. Comes with hand drawn schematic for repairing!!

I originally got this from a friend who said it had lived in a basement for ~30 years. I cleaned all the keyboard contacts of any rust and got the synth fully working for awhile. Then it crapped the bed and I had to bring it back to life for a second time. Since then it has acted a bit estranged and I haven't had much time to work on it. Im mainly trying to sell this since I moved into modular gear, but I used this unit for bass lines in many of my songs. Overall it has a vast sound selection for anyone looking for a vintage synth. Even with its altered function I find that I am still able to get a lot of amazing sounds from this device.

Several knobs have lost their intended travel however still retain their function and can act strange depending on their setting. I will list any issues that I have noticed thus far for anyone interested in obtaining this synth to refurbish. I will also try to fix the easy issues and take them off the list as I complete them.

CV modulation depth for the LFO and S + H has issue where the modulation is modest for most of the knobs travel and then increases depth around the last 70% of the turn.

If the sustain slider is below 3/4 of its travel, the envelope will re-trigger/loop in Attack - Decay mode for the duration of the gate signal. The lower sustain is the faster AD loops. This is a function that I believe is intentional as you can loop the ADSR with or without holding a key down however the speed aspect seems to be something that is wrong. That and the sustain travel is abnormal.

VCO modulates a VERY small amount by the envelope, just under a semitone, if the LFO is set slow or fast this is less noticeable.

All voice sliders will distort the mixing amp stage before the filter if turned up all the way. If voices are turned down a bit this does not happen.

Several keys will alter pitch after releasing, mainly due to how slow you release since the keybed is comprised of pairs of metal tines making contact with a metal bus bar for gate and CV. If the one of the tines is released before the other this is why this happens.

Some of the jacks are a bit rusty but still function 100%. I've had some moments where depending on the contact with the cable used, it may need to just be plugged in and out a few times to remove the outer layer of oxidation on the metal. Some de-oxit spray would also fix this.
Noise slider cap is missing.

Other than that the unit is still kicking and looking for a good home! I made a hand drawn schematic awhile back as well and can provide a copy when purchased to help with fixing the unit."

Vermona'14 solo, GRP A4 Sequence

Published on Apr 13, 2020 coyotesynth

"This video is a short teaser of the forthcoming album made by Fabien Labonde, album in which I did those 2 short contributions, as many other musicians.

Vermona'14 is a great and expressive analog monosynth, with many modulations (filter on modwheel, vibrato on aftertouch, great keyboard action). When Fabien asked me for a solo on this track, it was obvious the Vermona'14 would be the one to make it.

GRP A4 is used on a bass sequence later in the track.

Please note this is still under progress, it still miss real drums and other instruments, but what you hear are the final takes from my side."
