    CW: Euclidean Rhythm Generator Proof of Concepts

    Many hours later, and now I have a Euclidean Rhythm Generator sequencing blips. It's quite underwhelming, but the implementation is fully documented using #literateprogramming. It should end up in #sndkit in the next few days.

    This sound patch converts a metro signal into a euclidean rhythm which drives an envelope generator. It randomizes the pulse variable at every bar to regenerate the pattern:

    metro 8
    hold zz
    regset zz 0

    regget 0
    dup
    tdiv zz 8 0
    trand zz 2 8
    param 8
    euclid zz zz zz
    env zz 0.001 0.01 0.01
    sine 1000 0.5
    mul zz zz
    wavout zz "euclid.wav"
    computes 10
    unhold [regget 0]

    More experiments using #uxn to sequence Gesture in #sndkit!

    This one implements a concept I am calling "temporal skewing", which is the ability to locally warp tempo in a region without gaining or losing time overall. The neat thing about this is that it's all done using audio DSP!

    The melodic sequence below would have otherwise been playing linear eighth note rhythms, but was subjected to a exponential temporal skewing curve lasting 9 beats, causing an accelerando to happen. While the beats do get faster, the overall time is still 9 beats.

    Code found here:

    Some initial experiments getting #uxn to sequence #gestures.

    The featured gesture here is controlling the pitch of an oscillator with a small bit of glissando. Every time the gesture loops back, the speed changes: eighths (2), triplets (3), sixteenths (4), quintuplets (5), etc. until it reaches a really high value and then it goes backwards and slows down.

    I also programmed a secondary gesture that is controlling filter cuttoff. This is a line that rises up and down every 4 beats.

    Uxn program (tal) and #sndkit patch (LIL) can be found here.

    A randomly generated line is used to produce a quantized melody via qgliss. this line also maps to other parameters in the patch as an expression curve.

    Yet another experiment using #uxn as a sequencer with #sndkit (#uxnseq).

    This time, the goal was to build coordinated sequences. In other words, be able to have a sequence that has an awareness of another sequence, and reacts and behaves accordingly.

    The uxn program controls two sequences simultaneously. The first sequence controls a 7/8 bass line groove, and at each bar randomly chooses a new measure. The second sequence controls a sparse melody on top. It picks one of 2 pre-composed sequences based on what the first sequence chose.

    code (uxntal for sequence, LIL for sounds) can be found here:

    Tomorrow is the deadline for the #libremusicchallenge, and I think my #synthwavefromscratch track is in a good enough place for it.

    For those of you just joining in, for the past month, I've been making a synthwave track from scratch: no DAW, no plugins. Just C code and some scripting languages on top of that. In other words, I'm using my #sndkit and #gest projects.

    The code for the song can be found here:

    git.sr.ht/~pbatch/gest/tree/ma

    ...if you don't believe me, compile and render it yourself ;)

    LIL is such a cute little language. I introduced it into #sndkit last week as a way to build up patches.

    Here's some code used to generate a few sine waves:

    # mainly testing out hold/unhold functionality
    # one LFO controls the frequency of 4 oscillators

    # function to create a voice
    func voice {min max} {
    osc [regget 0] \
    [biscale [regget 1] $min $max] \
    [param 0.1] [param 0]
    }

    # generate sine table in register 0
    regset [gensine [tabnew 8192]] 0

    # generate held LFO signal in register 1
    regset [hold [osc [regget 0] 0.1 1 0]] 1

    # create 4 voices and add them together
