New Pattern Generator For Kyma 7.25


Symbolic Sound has released a new module that generates endlessly evolving sequences based on the patterns it discovers in a MIDI file. HMMPatternGenerator is now available to sound designers, musicians, and researchers as part of a free software update to what they describe as the the world's most advanced sound design environment: Kyma 7.25. Here's the story in the company's own words...

Composers and sound designers are masters of pattern generation — skilled at inventing, discovering, modifying, and combining patterns with just the right mix of repetition and variation to excite and engage the attention of a listener. HMMPatternGenerator is a tool to help you discover the previously unexplored patterns hidden within your own library of MIDI files and to generate endlessly varying event sequences, continuous controllers, and new combinations based on those patterns.

Here's a video glimpse at some of the potential applications for the HMMPatternGenerator:

What can HMMPatternGenerator do for you?

Games, VR, AR — In an interactive game or virtual environment, there's no such thing as a fixed-duration scene. HMMPatternGenerator can take a short segment of music and extend it for an indeterminate length of time without looping.

Live improvisation backgrounds — Improvise live over an endlessly evolving HMMPatternGenerator sequence based on the patterns found in your favorite MIDI files.

Keep your backgrounds interesting — Have you been asked to provide the music for a gallery opening, a dance class, a party, an exercise class or some other event where music is not the main focus? The next time you're asked to provide "background" music, you won't have to resort to loops or sample clouds; just create a short segment in the appropriate style, save it as a MIDI file, and HMMPatternGenerator will generate sequences in that style for as long as the party lasts — even after you shut down your laptop (because it's all generated on the Paca(rana) sound engine, not on your host computer).

Inspiration under a deadline — Need to get started quickly? Provide HMMPatternGenerator with your favorite MIDI files, route its MIDI output stream to your sequencer or notation software, and listen while it generates endless recombinations and variations on the latent patterns lurking within those files. Save the best parts to use as a starting point for your new composition.

Sound for picture — When the director doubles the duration of a scene a few hours before the deadline, HMMPatternGenerator can come to the rescue by taking your existing cue and extending it for an arbitrary length of time, maintaining the original meter and the style but with continuous variations (no looping).

Structured textures — HMMPatternGenerator isn't limited to generating discrete note events; it can also generate timeIndex functions to control other synthesis algorithms (like SumOfSine resynthesis, SampleClouds and more) or as a time-dependent control function for any other synthesis or processing parameter. That means you can use a MIDI file to control abstract sounds in a new, highly-structured way.

MIDI as code — If you encode the part-of-speech (like verb, adjective, noun, etc) as a MIDI pitch, you can compose a MIDI sequence that specifies a grammar for English sentences and then use HMMPatternGenerator to trigger samples of yourself speaking those words — generating an endless variety of grammatically correct sentences (or even artificial poetry). Imagine what other secret meanings you could encode as MIDI sequences — musical sequences that can be decrypted only when decoded by the Kyma Sound generator you’ve designed for that purpose.

Self-discovery — HMMPatternGenerator can help you tease apart what it is about your favorite music that makes it sound the way it does. By adjusting the parameters of the HMMPatternGenerator and listening to the results, you can uncover latent structures and hyper meters buried deep within the music of your favorite composers — including some patterns you hadn't even realized were hidden within your own music.

Remixes and mashups — Use HMMPatternGenerator to generate an never-ending stream of ideas for remixes (of one MIDI file) and amusing mashups (when you provide two or more MIDI files in different styles).

Galleries of possibilities — Select a MIDI file in the Kyma 7.25 Sound Browser and, at the click of a button, generate a gallery of hundreds of pattern generators, all based on that MIDI file. At that point, it's easy to substitute your own synthesis algorithms and design new musical instruments to be controlled by the pattern-generator. Quickly create unique, high-quality textures and sequences by combining some of the newly-developed MIDI-mining pattern generators with the massive library of unique synthesis and processing modules already included with Kyma.

How does it work?

If each event in the original MIDI file is completely unique, then there is only one path through the sequence — the generated sequence is the same as the original MIDI sequence. Things start to get interesting when some of the events are, in some way, equivalent to others (for example, when events of the same pitch and duration appear more than once in the file).

HMMPatternGenerator uses equivalent events as pivot points — decision points at which it can choose to take an alternate path through the original sequence (the proverbial “fork in the road"). No doubt you’re familiar with using a common chord to pivot to another key; now imagine using a common state to pivot to a whole new section of a MIDI file or, if you give HMMPatternGenerator several MIDI files, from one genre to another.

By live-tweaking the strengths of three equivalence tests — pitch, time-to-next, and position within a hyper-bar — you can continuously shape how closely the generated sequence follows the original sequence of events, ranging from a note-for-note reproduction to a completely random sequence based only on the frequency with which that event occurs in the original file.

Other new features in Kyma 7.25 include:

  • Optimizations to the Spherical Panner for 3d positioning and panning (elevation and azimuth) for motion-tracking VR or mixed reality applications and enhanced binaural mixes — providing up to 4 times speed increases (meaning you can track 4 times as many 3d sound sources in real time).
  • Multichannel interleaved file support in the Wave editor
  • New granular reverberation and 3d spatializing examples in the Kyma Sound Library

 

Pricing and Availability:
Kyma 7.25 is available now as a free update and can be downloaded from the Help menu in Kyma 7.
