KICKSTARTER: Lo-Fi SES: Hackable 8-bit instrument

lo-fi ses
lo-fi ses
The Lo-Fi SES (Sound Entertainment System) makes the process of playing an instrument easy by providing a video game controller interface for the lo-fi instrument. The d-pad allows you to change or record tracks, the buttons play the various sounds, and the l/r dials dynamically effect the frequency of the sounds as you are playing them.

A combination of things make this instrument unique. It is a fully open (hardware and software) audio platform, compatible with the Arduino ecosystem, and uses an innovative cart-based expansion system. Yay cartridges!!! The instrument is super approachable for level 1 musicians, but it is designed to be fun no matter what level you are at. The higher-level users can hack on the software via a “USB: a Link to the Hack” cart or even design a custom cart themselves. (I have a strong desire to see someone create a ridiculous rumble pack. You could make it rumble to the beat for some superfluous haptic feedback.) Also, the USB cart solves a common complaint for other lo-fi instruments: it allows you to swap out the sounds with ones of your own design!

The Lo-Fi SES lets you level up your music skills and look good while doing it. Join the adventure and we can rock out together!

Controlling a bent device with a digital pot, an arduino, and an LTC1799

Reader Writes: Hi, I wrote some code that easily and cheaply allows audio of any frequency from sub audible to ~8khz to control an LTC1799, or really anything that uses resistance to change a parameter. It’s also able to be controlled by internal 8 bit wavetables. Documentation of that will follow as well. I implemented this with just two chips-an Attiny85 and also an MCP41100 digital pot.

In this configuration, it also doubles as an 8bit DAC. It’s also possible to sequence relays from incoming audio to have tempo controlled sequencing of bends. I’m planning on adding midi code once I start working on the vanilla Arduino port of this.

Here are some examples of this idea in action.




The Adventure Time Module


This is my first real bend project after my initial toiling and destroying phase was somewhat over. This Module is based around my kids favorite cartoon. It’s downright a blast to fiddle with! This project contains my first Speak & Spell, which I permanent, as a second voice. It’s also an open bending platform for development and learning. Other features include: Dual modded PT2399 delay unit
Madbean’s loophole unit
Many casper electronic bends and glitches (his website is amazing)
An LFO w/clock out
and a second clock
All tricked out with my mediocre finishing skills.

This project swallowed me whole for quite sometime. It was a leaning experience to say the least. Check out the video to see this beast in action!
