A janky frame for the prototype resonator all-in-one thing. It’s unstable and I managed to measure the inner supports wrong so I’ll have to cut new side panels… but I think I can reinforce it, and maybe instead of cutting new side panels I can just make some kind of patch around the existing ones… that’s where the power supply, amplifier boards, and solenoid driver boards will attach, as well as the breakout connectors. Those connectors are great (tabs like on the back of a stereo) but also kind of a pain to attach to panels.

Testing a new sequencer for astrid. The pauses sound cool, but they are likely deadlocks. :-p

from pippi import dsp, oscs, shapes, fx, tune
import astrid

def play(ctx):
    steps = [
        [1,4,6,9],
        [3,5,7,8],
        [4,6,7,10],
    ]

    steps = steps[ctx.count//3 % len(steps)]

    freqs = tune.degrees(steps, octave=3, key='a')
    freq = dsp.choice(freqs)
    length = dsp.rand(0.015, dsp.rand(.25, dsp.rand(0.5,1)))
    length = 1.5
    ws = dsp.ws(ctx.adc(0.1), limit=dsp.randint(10,30))
    out = oscs.Pulsar2d(ws,
        pulsewidth=shapes.win('sine', dsp.rand(0, 0.9), 1, length=dsp.rand(0.1,dsp.rand(0.2,dsp.rand(2,20)))), 
        freq=freq * 2**dsp.randint(-2,2) + dsp.rand()
    ).play(length)
    out = out.taper(0.005).pan(dsp.rand())
    out = fx.lpf(out, dsp.rand(50,10000))
    out = fx.fold(out, dsp.rand(1,5))
    out = fx.norm(out, dsp.rand(0.2, 0.25))
    return out.env('pluckout')

def seq(ctx):
    length = 3
    beat = 0.25

    onsets1 = dsp.pat2onsets('xxxx.', beat, beats=32)
    onsets2 = dsp.pat2onsets('xxxx.', beat, beats=32)

    ctx.seq.set(0, length, onsets=onsets1)
    ctx.seq.set(1, length, onsets=onsets2)
    ctx.seq.set(2, length, onsets=onsets1)
    ctx.seq.set(3, length, onsets=onsets2)

Thursday October 9th

This is a sketch of a new resonator / amplifier / power supply / computer all-in-one design. The poles are the size I can get at the hardware store. Inside, the black rectangle in the center is my old framework mainboard in a standalone case. The other smaller black rectangle is an HDMI screen for the framework. On top in translucent white are two resonator panels sandwiched on top of each other. The bottom one will have an exciter, the top one will have one to many contact mics and be a sound-surface for objects etc.

Not pictured is a lot of other stuff I’d like to cram in, too. On the HDMI screen side, some more electronics: the battery power supply for the amplifier boards, and the amplifier boards and breakouts for speakers. Also! Potentially another battery power supply, the driver boards for the solenoids and motors and the USB GPIO breakout for the framework… finally a battery for the framework & the monitor!

To start: I need to stop by the hardware store and then build the frame. If it works, it will be interesting to experiment with closing the sides and seeing how that affects the sound. My dad has also offered to help build a proper version (he’s a woodworker) once I settle on a design.
