# otem/Raspberry-Pi-Looper-synth-drum-thing

My first venture into raspberry pi stuff. Running a custom pure data patch I've been working on for a couple years on a Raspberry Pi 3. This project took a couple months and I'm still tweaking stuff here and there but it's pretty much complete, it even survived it's first live show!

## What it is
A DIY Raspberry Pi-based looper/synth/drum machine running a custom Pure Data patch, with a Teensy 3.6 controller, custom button/drum-pad hardware, and a small display. It is a personal hardware music instrument project, essentially complete and used in live shows.

## Use cases
- build a raspberry pi looper and drum machine
- run a pure data patch on a pi as a standalone instrument
- make a diy hardware synth with teensy and buttons
- looper for live electronic music performance
- custom drum machine with my own wav samples

## When to choose
- you want to build the exact documented hardware setup (Pi 3, Teensy 3.6, ILI9341 display, mux, pots)
- you already use Pure Data and want a dedicated embedded instrument
- you want a hackable looper/drum machine you can modify at the patch level

## When to avoid
- you want a polished, supported product or general-purpose audio software
- you don't want to source specific hardware and wire it yourself
- you need a maintained project with a license, releases, or community support

## Facets
- artifact type: application
- maturity: maintenance
- function: audio-processing, embedded, gui
- domain: embedded-systems, hardware, audio
- platform: embedded, iot, cpp
- tags: raspberry-pi, pure-data, teensy, looper, synthesizer, drum-machine, diy-instrument, live-performance, audio
