Rossum Electro-Music Trident Multi-Synchronic Oscillator Ensemble Zing Modulation Demo

Published on Nov 25, 2019 Rossum Electro-Music

"The latest brainchild of synth pioneer Dave Rossum, TRIDENT is a 100% analog, triple oscillator module that opens up a universe of dynamic timbral textures.

At its most basic level, TRIDENT is three precision audio VCOs, each sporting a unique variety of control voltage inputs.

The main or “Carrier” oscillator provides its three waveforms simultaneously. The two Modulation Oscillators each have a single output and a waveform selector. The Modulation Oscillators also have a voltage controlled Symmetry parameter which varies the duty cycle of the triangle wave output from sawtooth to triangle back to time reversed sawtooth, and also varies the sawtooth output to have an upward or downward kink in the middle, as well as controlling pulse width when the pulse waveform is selected.

And while each oscillator can be used independently if desired, it’s when they’re combined into a synchronous ensemble that the real sonic magic happens.

That magic is what we call Zing Modulation. Each of the Modulation Oscillators can modulate each of the Carrier outputs in an amount controlled by the Zing parameter. Zing Modulation is mathematically akin to ring modulation, but due to the synchronization of the oscillators (when an oscillator’s Sync button is on), the aharmonic sum and difference sidetones of ring modulation transform into complex but purely harmonic overtone spectra, which vary dynamically and dramatically with the frequency and waveshape modulations of the modulation oscillators. Each change in the Modulation Oscillator parameters – Frequency, Symmetry, Waveshape, Zing, and (in the case of Modulation Oscillator 2) Phase – will have a different effect on the timbre of each of the three Carrier waveshape outputs.

When the modulation oscillators are set to track the carrier oscillator, the waveshape will remain constant as the carrier frequency changes. In this case the overtone structure is determined by the settings and CV modulations of the modulation oscillators. If instead the modulation oscillators do not track the carrier, some of the overtone structure will vary relative to the carrier frequency.

What all this means is that whether you take advantage of Trident’s unique synchronous modulation capabilities (which you, of course, should), or just treat it as three superb, wide-range analog oscillators, TRIDENT offers a vast variety of dramatic sonic textures."

Introducing Orba by Artiphon – An instrument designed for your hands

Published on Nov 25, 2019 Artiphon

Artiphon brought us the INSTRUMENT 1. The Orba is currently seeking funding on Kickstarter.

"Hold out your hands and meet Orba, a new kind of musical instrument. It’s a tiny synth, looper, and MIDI controller that lets anyone make music immediately. Orba’s minimalist design resembles a cross between a gaming controller and a half a grapefruit, and its feather-touch sensitivity translates gestures from your fingers and hands directly into sound. Orba introduces a new and fun way to make music anywhere, even if you’ve never played an instrument before."

Onboard synth:

"We designed an innovative new synthesizer engine for Orba, with a broad range of synth sounds that work seamlessly with various playing gestures. Orba’s embedded looper means you can layer multiple parts without ever looking at a screen. The built-in speaker lets you make sound immediately (and it’s loud enough for a bit of karaoke). Plug in headphones to play alone or an external amp to play it loud.

The Orba companion app lets you explore even more. Available for Mac, iOS, Windows, and Android, the Orba app will let you access more sounds, presets, loops, and settings. The app is also where you’ll be able to save and edit your loops and songs. And of course, you can share your songs to social media and export to your favorite music-making software to keep building your beats."

No word on how programable the synth engine will be. That will of course determine how much the Orba is more of a controller and performance device vs. full fledged programmable synth.

Eight capacitive-sensing pads for feather-touch control

Accelerometer and gyroscope capture a range of gestures

Center menu button accesses four presets, the looper, and other functions

Onboard synthesizer and built-in speaker offer an immediate playing experience

Connect to the cross-platform Orba app for more sounds, songs, and settings

33 1/3: Wendy Carlos's Switched-On Bach - Talk By Roshanak Kheshti

Published on Nov 25, 2019 Perfect Circuit

"UCSD Associate Professor of Ethnic Studies Dr. Roshanak Kheshti came to Perfect Circuit to present a short lecture and reading from her new book 33 1/3: Wendy Carlos's Switched-On Bach, combined with examples on her own Moog synthesizers.

Kheshti makes a case that Wendy Carlos is one of the most important electronic musicians of all time: she brought an emerging technology into public visibility and was a strong force behind the popularization of the Moog synthesizer. Switched-On Bach remains one of the most popular "classical" music records of all time...and for a good reason.

Animated Graphic Scores Performed on the Novation BassStation II

Rain Published on Nov 16, 2019 John Keston

"Strands is the working title for a series of audiovisual compositions based on the idea of animated, generative, graphic scores. Last year I composed six of these scores written in Javascript for Parking Ramp Project, a performance installation in a seven-level parking ramp with a large cast reflecting on transience, migration, and stability commissioned by Guggenheim fellow, Pramila Vasudevan. While Parking Ramp Project was composed for a trio, Strands is specifically composed for a soloist.

Rain is a new movement in the series and the first that I have produced with video of the animated score. Currently there are five movements in the piece. I performed the first four recently at the ISSTA conference in Cork, Ireland. The visual part of the piece is meant to be read like music but without the use of key or time signatures. Each time the piece is played the visuals are regenerated, so it is never performed the same way twice.

The musician may interpret the visuals in many ways. For example, in Rain lines are animated from the top of the screen to the bottom. Where the line appears horizontally is roughly regarded as pitch and as the line animates the sound is modulated. The lines also vary in weight. Heavier lines are louder and lower in pitch while thinner lines are quieter, generally higher, and sometimes altered with a high-pass filter.

I performed Rain using the Novation Bass Station II, which has a feature (AFX mode overlays) that allows for each note to have entirely different parameters. With this technique I was able to map different timbres to the keybed and use this variety in texture as another way to interpret the score. Keep an eye out for more of these. It is my intent to make videos for all five of the movements and perhaps add one or two more to the series."


Premiered Nov 24, 2019 John Keston

"Generator is the next piece in the Strands series. These audiovisual compositions illustrate the interpretation of animated, generative, graphic scores written in Javascript. Generator is made up of connected line segments that that go from left to right, up, or down, but never in reverse. The weight and length of each segment is consistent across the width of the screen and changes once a new set of segments starts again from the left.

I interpret each set of segments as an arpeggio. The tempo of each arpeggio is decided by the segment length. Shorter segments, drawn more quickly, are paired with faster arpeggios. As the line segments wander up and down I generally interpret the Y axis as pitch, but because the direction of each segment is random the pitches are not exact representations of the paths that are displayed; neither is it the intent to exactly follow the visuals. Instead, musicians interpret the score so that human qualities contrast the computer generated visuals.

The aesthetics of the pieces in this series, both visually and sonically, are secondary to the objectives. First that the scores are composed for the purpose of being read by musician(s). Secondly, the artist(s) have space to improvise within their interpretations. Thirdly (in addition to interpretation) aleatoric elements make the pieces significantly different from one performance to the next. Finally, although the performances vary, distinct characteristics identify each piece.

The objectives of these pieces lead to music that is often atonal and/or atemporal. After about a dozen rehearsals, performances, and recordings with a trio and as a soloist it has become apparent that tonality and timing often do emerge. For example, in Generator the tempi of the arpeggios change with each animated progression from left to right. Arbitrary rests are interspersed with random lengths. This amounts to timing without time signatures. And, since the pitches are left up to the artist the notes performed may or may not be in key. In my performance I chose to use a variety of intervals and scales leading up to the chromatic scale at the conclusion."

Arturia Microfreak / Korg Volca Modular and Drum - Minijam 2019-11-24

Published on Nov 24, 2019 Oscillator Sink

"Recently I've been enjoying exploring the darker side of some of my synths and in this jam, the Microfreak along with the Volca Modular and Volca Drum are getting dark together.

The Volca Modular is providing a kind of groaning, grinding, industrial drone which is being enhanced by the Zoom MS-CDR70 and its excellent "Mangled Space" reverb algorithm (seriously, it's worth the price just for that). I'll post a photo of the patch on my Facebook page. The Volca Drum is providing various melodic and percussive elements - including a massive bass pulse; the Volca Drum is providing its own Delay via the Wave Guide with the "Tune" control set super low.

The Microfreak is set up as a king hybrid pad/pluck Karplus Strong kinda thing. The patch has an element of "controlled chaos" to it, and applying more pressure to the keys makes the patch get more frantic - almost like you're influencing another player rather than the instrument directly. It's an idea I've really been digging recently and it might form the basis for a patch pack...maybe...we'll see."

"2 years ago when I plugged in the keyboard it made one sound that was constant and unalterable. Today there was no sound. The keyboard was unattached to the base but it only needs two screws. The keyboard was also unattached from the rest of the circuitry. I reattached it with no discernible results. The glass over the led light on the left upper corner of the keyboard is broken but the light works. There is no power cord for this keyboard but it is the same type of cord that's used for a computer monitor which is easy and cheap to obtain."

ELTA SOLAR 50 | Big Drone synth | Ambient machine (prototype demo)

Published on Nov 25, 2019 ELTA music

"This is performance oriented analog electronic music instrument! Big ambient machine, drone-accordion, organ and 50 oscillators synthesizer all in one!

Final version will include a new design and additional, yet not showed functions. Estimated price is about 800$.
Pre-orders at Mark 'SOLAR 50'"


"The instrument is designed for creating atmospheric sounds, background music, microtonal music, super polyphonic electro symphonies, as well as for making sophisticated complexes of extensionally dispensed tones that have random frequencies and tricky intervallic hookups. Inspired by early electronic musical developments of the last century, particularly Leo Theremin's instrument called 'Harmonium'.

Variations of sounds that you can create with «Solar» are really boundless.

Solar synthesizer consists of 10 voices. Each voice, in it’s turn, consists of 5 oscillators (2 low, 2 middle, 1 high) with a pitch controller and a mute button for each oscillator. Each voice is provided with an envelope (attack/release parameters) controlled by a tactile sensor.

Solar 50 has a piezo mic onboard, that let it turn into electro acoustic percussion noise instrument.
In addition, there is a GATE-ON button for every voice, making it sound constantly, and a voice volume controller.

There are two independent LFOs and a bunch of external CV inputs on board and so called PLS connector for connecting a CV source in order to control the pitch of each of 50 oscillators and to start the envelope of any voice. Patching is possible with standard pin wires that are used in Moog Werkstatt, Bastl Instruments and in many other devices. MUTE buttons let you use from 1 up to 5 oscillators per voice, tuning in for chords, thirds, fifths and other intervals or to get a clean single note.

Behringer Introduces the POLY D - 4 Voice Paraphonic Polyphonic Minimoog Keyboard Synthesizer

Published on Nov 24, 2019 BEHRINGER

Apparently Behringer is on Amazon now.

Update2: Playlist with three user videos (you can skip around on the top right or bottom left):

Sonic Lab: Behringer Poly D! - sonicstate
Behringer Poly D -solo sonidos / only sounds -
Behringer POLY D - MrFirechild
Behringer POLY D: Review, Tutorial and Patch Ideas // Auto-damp explained - loopop

Update: post updated with larger pics. Click them for the detail.

Note the POLY D is more like a Mono/Poly in how you stack/route the oscillators. There are 4 VCOs, so you can set them to trigger one at a time for 4 voice paraphonic polyphony. Paraphonic in that they share the same filter, envelopes, etc. You can't have a fully separate voice with independent filters, envelopes, etc like on a truly polyphonic synth. This is not a Memormoog or Moon One. That said, it is a step ahead of a standard Minimoog - 4 vs 3 VCOs with the ability to play paraphonically. If it's light enough, you might even be able to kick back on a couch with it. An original Minimoog on the lap would get heavy fast.

Side note: Apparently Behringer is on Amazon now.

Details from Behringer:

"Analog 4-Voice Polyphonic Synthesizer with 37 Full-Size Keys, 4 VCOs, Classic Ladder Filter, LFO, BBD Stereo Chorus, Distortion, 32-Step Sequencer and Arpeggiator"

The 1970s spawned the first truly portable analog synthesizer, and while it was quickly adopted by lots of renowned musical artists including Jan Hammer, Chick Corea, Rick Wakeman, Jean-Michel Jarre, Isao Tomita and Keith Emerson to name a few, it was somewhat temperamental and very expensive. An ultra-affordable homage to that iconic synthesizer, with all the features of the original and then some, the Behringer POLY D lets you conjure up virtually any monophonic or polyphonic sound imaginable with incredible finesse and ease. The pure analog signal path is based on authentic VCO, VCF, VCA and ladder filter designs in conjunction with a dedicated and fully analog triangle/square wave LFO. Owning a POLY D is like having your own personal time machine, enabling you to freely embrace the past – or shape the future!
