Instant Cinema: Duet for Synthesizers and Mobile Conductor

Published on Nov 10, 2013 John Keston·27 videos

"Duet for Synthesizers and Mobile Conductor is a piece composed and performed by John Keston in collaboration with David T Steinman who also performs in the piece as the mobile conductor. Steinman creates a real-time audiovisual score that is broadcast into the performance space from a remote location. This score consists of textural, atonal, and arrhythmic "sound features" produced with artifacts from Steinman's apartment. The imagery and amplified sound become content within the music as it is interpreted through improvisations by the synthesist, John Keston. Keston accompanies the sound features while controlling three analogue synthesizers (Novation Bass Station II, Korg Monotribe, and Korg Volca Keys). This use of an audiovisual score is a means to harness the sensory influence of non-musical sounds and images in our environments, elevating these sources to compositional structures.

Duet for Synthesizers and Mobile Conductor was performed on November 7, 2013 at the Strange Attractors festival, St. Paul, Minnesota. This video was captured during a private performance made shortly after the public showing. The piece was made possible by a grant from the American Composers Forum with funds provided by the Jerome Foundation.

Ostracon Video

Ostracon Video from Unearthed Music on Vimeo.

"Shot by Ai student Josh Clos. Recorded and mixed at Ai Minnesota by John Keston and Graham O'Brien.

Ostracon is John Keston on electronics and Graham O'Brien on drums. The duo performs generative, improvisational compositions using John Keston's custom software, the GMS (Gestural Music Sequencer), that converts video input into musical phrases. Keston captures, layers, loops and processes melodic segments in real-time out of the stream of notes created by his gestural input, tailored with probability distribution algorithms. O'Brien accompanies these angular, electronic structures, with dynamic playing that, at times, verges on the chaotic."

RedSound Darkstar Demos & Review by Ostraka (John Keston)

Great demos.  Check out the full review on Audio Cookbook.  According to the review the DarkStar was the "Internet's most reviled synth".  I don't recall this, but then I didn't spend too much time in the forums after launching MATRIXSYNTH.  I have an XP2 myself and love it, although the interface does take a little getting used to.  It appears John Keston is pro Darkstar as well:

"For me the DarkStar fulfills a spectrum of features that I’ve been looking for in a desktop poly. It has a low profile so I can use it along side a collection of other devices while performing. It has eight voice polyphony allowing me to produce dense harmonies. It has a bloody joystick to control the filter and resonance! The joystick can also be configured to control ring modulation and oscillator mix. Many knobs make sculpting the sound in realtime possible. The LFOs have ramp, triangle, square, sine, pulse, sample & hold, and “random” waveforms. What random does is pretty remarkable. Similar to slew on the Novation Bass Station II, it interpolates or slides between random values instead of jumping to them like sample & hold does. This is especially nice for panning and one of the things that distinguishes the DarkStar from other VAs of the time."

Vocalise Sintectica - John Keston - ISSTA 2017

Published on Apr 19, 2018 Daryl Feehely

"John Keston performing Vocalise Sintectica at the ISSTA 2017 concert in DkIT."

On what's going on in this performance via Audio Cookbook:

"Last September 2017 I performed at the Irish Sound in Science Technology and the Arts Conference (ISSTA.ie) in Dundalk, Ireland (video by Daryl Feehely). The performance makes use of a custom Max patch controlled by an iPad, a Novation Circuit, a KeyStep, and a Minifooger Delay pedal. It occurred to me that it might be interesting to share the roots and evolution of this piece, so here goes.

In my mind the origins of the piece can be traced back to my interest in granular synthesis. In 2009 I developed a Max based instrument I titled Grain Machine. It was essentially a touchscreen controlled granular synthesizer. I used this instrument for a number of projects including Words to Dead Lips, a dance piece in collaboration with Aniccha Arts. The instrument was played via a simple iOS interface designed in TouchOSC. A performer could access five samples, granulate them on an X-Y grid, or spin a virtual wheel with friction modeling to scrub or scratch through them..."

Voice Lessons

"Voice Lessons
by John Keston

Voice Lessons is an electronic, audio device that interrogates the popular myth that every musical instrument imitates the human voice. Touching the screen allows the participant to manipulate the visuals and vocalizations of the “voice teacher” as he recites vocal warm up exercises.

The piece resides in the space between a musical instrument and voice lesson. Move the touch point left, right, up, and down to explore the visual and auditory possibilities. Rapid high pitched loops occur while touching near the top of the screen while lower pitched longer loops are heard near the bottom.

The actor, also named John Keston, is the artist's retired father who became a voice teacher after a long career on stage in plays, operas, and musicals with the Royal Shakespeare Company in his native country England and abroad.

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.

Generator

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.

Exploring PreenFM2 with Max for Live PreenFM2 Patch Degrader

The above is a composition by John Keston featuring PreenFM2 being manipulated by a custom patch he created with Max for Live. According to John, the patch "allows me to degrade, morph, and/or scramble sets of parameters on the synth. This is similar to a device I designed for the Yamaha TX81Z. This process creates an algorithmic approach to the sound design." You can read all about it on his site AudioCookbook.org here. The following is a screenshot of the patch and the description for the track above.  You can click the image for a larger version.

Note John is heading to ISSTA 2018 for an upcoming performance utilizing his custom patch and PreenFM2. See his site for more info.

"MODULATOR is a series of pieces composed using a sequence of stochastic, deliberate, and arbitrary processes. A hybrid of algorithmic and improvised methodologies were devised to evolve textures beyond aesthetic considerations allowing peculiar, harsh, and even grotesque sounds to emerge. These processes were applied to a particular hardware-based, FM synthesizer called the PreenFM2. The instrument uses carrier and modulator waveforms organized through a series of algorithms to create a nearly infinite array of complex synthetic sounds.

The series was composed using custom software developed in Max for Live that morphs parameter values on on the synth. The values, applied to a pool of possible parameters, are interpolated over time to new values using a multi-threaded technique that allows many parameters to be changed simultaneously.

Because of chance factors in the algorithms the textures and rhythmic content will be significantly different each time the piece is performed. However, some identifying characteristics are maintained, such as how the performer “plays” the algorithm, and the peculiarities of the FM synthesizer."

Duet for Synthesizer and The Singing Ringing Tree

Published on Jul 21, 2014 John Keston

"This is the first from dozens of takes during a five day recording session and performance series at the Singing Ringing Tree (SRT) in Burnley, UK, a wind activated musical panopticon in Northern England. The sculpture was designed by architects Tonkin Liu and completed in December 2006. I performed accompaniment for the SRT binaural recordings simultaneously using a Novation Bass Station II connected to a USB battery. I also ran the Bass Station II through a Moog Minifooger Delay.

NOTE: This is a binaural recording combined with a monophonic synthesizer track. Although it sounds great through speakers, circumaural headphones must be used to experience the binaural effect."

TX81Z Patch Degrader Demo

Published on Aug 8, 2015 John Keston

"This quick demo illustrates how TX81Z Patch Degrader is interpolating between the previous and newly generated parameter values. TX81Z Patch Degrader is a Max for Live MIDI effect that chips away at patches on the TX81Z by randomly changing (or degrading) parameters at a specified rate. What makes the process interesting is that it is now possible to ramp up or down (or interpolate) to the new value rather than changing it instantaneously.

To create the Max for Live MIDI instrument I started with TX81Z Editor 1.0 (http://www.maxforlive.com/library/dev...) by Jeroen Liebregts who was kind enough to share his work on maxforlive.com. I added in the degradation process features and made some adjustments to the interface to make room for the controls. Once I get things shaped up I'll be happy to share the patch if anyone is interested.
