It was confusing people at the event that my portable DSP stack was running on Daisy hardware, so naturally I built it for ARM Linux hosts as well 😂 Audio was captured directly from the application, no added FX. The full Sound Byte Labs audio stack will be open source when it hits beta. #dsp #oss

If you're in Chicago come see what I've been up to next Sunday! I'll have half a table and some fun prototype gear to play with! Tons of other boutique and not-so-boutique vendors will be there too 🎸🎹🕺 #chicago #synthsky #marz #fleamarket

I promised diagrams, so here! Gatekeeper is a utility module with 2 buttons, CV in, Gate out, and status LEDs. The module is in one of 3 application states: Init, Perform, or Menu. While in Perform or Menu, the CV input controls the gate output. In the Perform state, you also get 2-button control

- Gate
- Trigger
- Toggle
- Divide

MIDI makes me grouchy, but mostly because of the historical 8 bit-ness of it. I also think it's too tied to western keyboard conventions, but mostly everything has decent fixes or workarounds these days. I'm having a lot of fun controlling the 0-Coast with a combo of MIDI and CV! #modular #synthsky

Okay, the EP-40 Riddim is just straight up fun! 🕺🎹 It has some really nice upgrades over the KO 2, although I wonder if some will trickle down. I love the new synth engines and the improved looper! Btw this was my "portable" set up down at my parents' farm 🤣 #modular #synthsky #teenageengineering

Modular synths are not for everyone, but they are definitely for me! I absolutely love patching this thing from scratch 🤓 Other signs you might love modular include thinking: - You would rather die than use presets - Money isn't real - 12TET is a prison for your boundless creativity #synthsky

I've had a K.O. II since shortly after release and not only have they addressed almost all the shortcomings since release, it's just downright one of my favorite instruments to play! It's my go-to drum machine, idea sketch pad, and messing around toy. Sequencing MIDI with it is next level! 😎🕺

I avoid politics-posting here but I will say: if you are upset about something, try writing a letter to your elected reps instead of shouting into the wind on social media! It shapes the conversation and they do pay attention when people make extra effort to reach them, especially many people.

A currently working vertical slice example from the Sound Byte Libs firmware library! This level of abstraction and ease of set up have been my north star while working on the library APIs. This code runs on a variety of ARM microcontrollers and a native simulator by changing only a CLI arg! #diy
A screenshot of code. The code is the main function for an embedded hello world LED blinker in C++.

The code is:

#include "sbl_config.h"
#include <sbl/api/widgets.hpp>

int main() {
    SBL_PLATFORM_INIT();
    
    sbl::api::widgets::Blinker blinker(SBL_LED_PIN, true);  // Board default LED, active-high
    blinker.start(500);  // 500ms interval

    while (true) {
        blinker.update();
    }

This has been a really fun patch to play with! Routing my computer's audio into the Palette case for listening and sampling. I have the MFD cross fading the sound source for Morphagene between the audio line in and Rings. It's fun to just listen to music or sample it and process it! #synthsky

So based on this (very good) book I'm reading, I'm no longer sure if I'll be able to fit the Shapeware 1U analog wave shaper circuit in 6HP without making some serious compromises. It could surely be done by robots, but for now I need to keep things hand solderable! Need more opamps 👀 #synthsky

This synth has been a lot of fun to play. I became obsessed with building a case around Morphagene that would be fun to play without a keyboard. Im glad I stuck with Pressure Points, because it's got a very musical response! Don't listen to the Maths haters out there! #modular #makenoise

Here is my 'compact' Eurorack module power circuit. Since modular supplies are usually pretty stable, you could probably lose some of the caps if you wanted. Theoretically, the smaller caps filter high frequency noise, and the bigger ones stabilize the slower oscillations in the supply.

Ever since I learned a simple debounce circuit for buttons, I've always preferred to debounce in hardware. You can build a nice filter circuit with a resistor and a capacitor. The capacitor charges and holds the line high for a few ms after you let go of the button. Prevents multiple rising edges!

Now I'm kind of obsessed with using the button module as a CV-Gate converter with audio rate signals. I'd need to tweak the design a bit more to allow it to output negative voltages (0-5V only right now). Could drop the toggle mode and go full analog 🤔
