Teensy USB Development Board
The Teensy is a complete USB-based microcontroller development system, in a very small footprint, capable of implementing many types of projects. All programming is done via the USB port. No special programmer is needed, only a standard "Mini-B" USB cable and a PC or Macintosh with a USB port....

Audio Library For Teensy 3
The audio library is collection of objects that play, synthesize, mix, analyze and apply effects to audio streams. All audio processing is done automatically in the background. Arbitrary connections may be made between any number of audio objects, to enable easily building advanced audio application in Arduino sketches. ...

The Teensy Becomes an MPC
A staple of every recording studio today, the Akai MPC began as a simple sampling groove box in the early 90s. The form factor of a few force sensitive pads assignable to different samples should be familiar to anyone with a little bit of MIDI gear, but these are rarely custom-made devices. Now, it runs on a Teensy. ...

Teensy Audio Spectrum Analyser
The Teensy Audio Spectrum Analyzer is a low-cost classic audio spectrum display with up to 128 bands.
The Teensy Audio Spectrum Analyzer displays a detailed picture of what you're hearing in real-time. It shows the changing spectrum of live input signals up to 16kHz.
It takes a mono analog RCA audio input (nominal 1v pp) and presents a live colour spectrum display with peak metering.
You can easily observe the frequency characteristics of live music in real time. The spectral composition of acoustic signals become clearly visible.

Arduino MIDI - Pieter P, 08-03-2017 - This is a guide that covers the basics of the Musical Instrument Digital Interface (MIDI) protocoland its implementation on the Arduino platform.The format of the protocol is explained in the first chapter. Chapter two goes over the hardware.In chapter three, example code for sending MIDI is presented. Chapter four contains everythingneeded to build a working MIDI controller. MIDI input is covered in chapter five, and chapter sixextends this by adding support for System Exclusive (SysEx) messages.

"Bastel-Rechner Teensy 4.0 bringt mehr Geschwindigkeit auf geschrumpftem Board" Helga Hansen (09.08.2019)
Passend zum Namen ist der neue Teensy 4.0 wieder winzig, arbeitet dank des ARM Cortex-M7 aber deutlich schneller als seine Vorgänger.
Gestenerkennung, Sprachausgaben und Echtzeitaudioanalysen – mit dem neuen Teensy 4.0 soll das auf Mikrocontrollern einfach umzusetzen sein. Das kleine Board bringt dafür den ARM Cortex-M7 mit 600 MHz und ist laut Hersteller PJRC mehr als fünf Mal schneller als sein Vorgänger Teensy 3.6. Dazu kommen 1024 K RAM und 2048 K Flashspeicher. Prinzipiell sei sogar noch mehr Geschwindigkeit möglich, denn der Chip lasse sich übertakten.
Hinter der dicht gepackten Pinleiste verbergen sich außerdem zahlreiche Anschlüsse: zwei USB-Ports, drei CAN-Busse, drei digitale Audio-Anschlüsse sowie 3 × SPI, 3 × I2C und 7 × seriell. Die Größe und Form sind wieder an den Teensy 3.2 angelehnt, mit dem das Board auch weitestgehend pin-kompatibel ist. Die Teensy-Versionen 3.5 und 3.6 waren zuletzt etwas in die Breite gegangen.

Teensy Drum Sample Player (05.11.2018)
Learning how to use Teensy audio libraries and the audio board to generate drum synth sounds and play back percussion wav samples. 
Using the online Teensy audio design GUI, the skeleton of the sketch can be auto-generated after visual audio blocks are dragged onto the workspace and inputs/outputs are connected with patch cables. 
Once the Arduino code is exported, the settings for those audio blocks can be controlled in the sketch. 
WAV files containing audio samples can be converted into hex data, compiled into the sketch, and played back from memory.
