    It is indeed polyphonic. Look at the library’s PlayFromSketch example.

    Maybe this will help?

    Here’s a message with quick/unofficial current measurements on the new 3.1 version.

    TL;DR = 32 mA at 96 MHz , 23 mA at 48 MHz , 15 mA at 24 MHz

    The speed is selected in Arduino using the Tools > CPU Speed menu.

    Yes, it really truly does have 64K of RAM and tons of other features far beyond Arduino Uno.

    An audio shield is being designed. If you’d like to chime in with any input, or just follow the development, here’s the page where it’s being discussed.

    Hi, Paul here from PJRC. I’m concerned about this problem. If you see this reply, please post a message on the PJRC Tech Support Forum with the details.

    To investigate this problem, I really need you to post the complete Arduino sketch which reproduces this problem. I’m currently working on Teensyduino 1.16. The SD and SdFat libraries are a priority. If this isn’t easily resolved, after 1.16 releases I’ll dig into the SD / SdFat code if necessary. But I need you to give me a starting point that reproduces the problem.

    For using it with “your favorite IDE”, there are a few 3rd party projects targeting the most popular environments. Hopefully one of these is your favorite?

    If you prefer Eclipse, Jantje’s Arduino Eclipse plugin supports Teensy. Here’s some links:

    If you love Xcode (Mac only), the embedXcode plugin supports Teensy.

    . http://forum.pjrc.com/threads/169-embedXcode-Teensy-3-0-on-Xcode

    If Visual Studio (Windows only) is your game, the Visual Micro plugin recently added support for Teensy 3.0. Here’s the link:

    If you’re a command line minimalist who only gets slowed down by any GUI, a good makefile is probably all you need. After you install Teensyduino into Arduino, the sample makefile is in hardware/teensy/cores/teensy3/makefile (on a Mac, control-click Arduino, choose “Show Package Contents” and dig down a few folders to find “hardware”). The makefile has comments with advice about which directories from Arduino you need to save, and which parts you can delete.

    All 3 of the IDE plugins are third party projects. They’re separate projects from Teensy. If you use them heavily, please show them some support.

    The Teensyduino download is 22 megabytes for the Windows version, 30 megs for Mac, 24 megs for Linux. (full disclaimer: I’m the author of Teensyduino!) Those sizes are for version 1.13. Like all software, the size will likely change over time as more capabilities are added.

    Teensy runs very similarly to regular Arduino boards. Your code runs directly on the hardware with true real time access, just like Arduino… except the ARM processor is faster than AVR and your code is 32 bits, so using “byte” and “long” are the same speed. All the normal functions like digitalRead, pinMode, analogRead, analogWrite, pulseIn are supported. Many of the widely used Arduino libraries are supported (and numerous others also work). Here’s the official library list for Teensyduino:

    Teensy does NOT run Linux like Raspberry Pi. If you give it a try, you’ll discover it works very much like Arduino. Probably the biggest difference you’ll notice is the Upload process is much faster!

No public wish lists :(
