Free Software Synth, Xynthesizr, Combines Matrix Sequencing With Generative Algorithms

xynthesizr

Developer Yuri Turov has released Xynthesizr, a free software synth that combines matrix sequencing, generative music features & a full-fledged synthesizer.

With its synthesizer and morphing features, Xynthesizr can be a classic ToneMatrix, an arpeggiated synth, a soft ambient generator,  a drone machine and more.

Features:

  • Audiobus support

Sequencer features:

  • 1-32 steps variable pattern length
  • Shake to clear
  • Tempo control (1-300 BPM)
  • 2 pattern morphing algorithms: [Conway’s Game of] Life-like cellular automata and randomized
  • Extended range (26 notes for 4-inch screen devices, 22 notes for 3.5-inch)
  • Selectable keys and scales
  • Ability to tie consecutive notes of same pitch (effectively making them one long note)
  • Color-coded octaves
  • Scalar transposition

Synthesizer features:

  • 16 voice polyphony (12 for iPhone 3GS)
  • 2 oscillators per voice
  • 4 selectable waveforms (sine, triangle, sawtooth, square)
  • Detune control
  • 4-pole (24 dB/oct) low-pass resonant filter
  • 2 ADSR envelope generators (amplitude and filter frequency)
  • 2 LFOs
  • 4 selectable LFO targets (filter frequency, pitch, amplitude, second oscillator detune)
  • Stereo reverb and randomized panner

Available via In-App Purchase:

  • Record and export audio via SoundCloud, Mail and iTunes File Sharing
  • Create your own scales and Life-like cellular automata rules
  • Save your presets and patterns

Xynthesizer is available in the App Store.

    1. Tempo and 32 note don’t work (using iPhone4). Really liking the random and game of life algos. Really wish there was a mod matrix and/or a sequencer to control the “chance” on random so I could play the same sequence a few times and then change it. Gave me an idea that you could mix the game of life algo’s life-expectancy/creation with the random’s chance algo.

      1. Tap the tempo, hold and slide left or right, and you’ll see the speed change. This is a nice implementation and gets around your thumb covering the number or having to tap on tiny buttons. 🙂

        Cool app!

      1. looks cool… but the sound doesn’t exactly seem to much in common with the automata being represented. More interested in something more dedicated to animation (which I haven’t really found yet outside maybe a java script (any recommendations there?)). Thanks

          1. Thanks for that, looks like fun; I’m not sure if these are closer to what you’re after, but here are some links anyway:

            There are some other pretty cool generative music apps for iOS, let me know if you’re interested, and I can post some App Store links.

  1. This is is fantastic, however I really wish it had two things:
    1) a “Clear Pattern” button, and
    2) External MIDI sync

    Other than that, this rocks!

    1. Shake to clear pattern. Tap and hold on the number of steps or tempo and slide your finger up so you can see the value, then slide left/right to change value.

  2. The documentation (i.e., the HELP section in the settings) only describes a couple things in the software. I was not able to adjust the tempo or number of steps on my device. Also, the way the IAP’s are set up, you don’t get to see what the interface for creating custom scales looks like. While the randomized pattern generation is kind of interesting, the lack of rhythmic controls and the absence of docs & demos made deleting the program a no-brainer.

    1. This is the response from the developer regarding changing number of steps, stolen from another forum:

      The way these controls currently work is following: you touch down on the control and slide your finger to the side (outside the actual control). The further you slide, the faster the value changes. Now I have to agree that this is not really smart and intuitive. I’m planning to address this issue in an update.

      Hope that helps.

  3. This is an absolute belter of an app – the iaps are well worth it. Changing tempo & steps is a breeze once you have applied some lateral thinking outside the box (literally!) If the dev continues with midi & audiobus etc. it will be a top piece of kit. Very inspiring.
