  This is an insteresting concept: solenoids play glockenspiel imitating you while you play the strings. It is called the Glockentar and made by Aaron Sherwood .

Matt built a 4-oscillator digital oscillator running on an ARM Cortex-M0 . And it's awesome!

Great news for all you guitarists out there: ElectroSmash have created pedalSHIELD , which allows you to download, or if you know C/C++, even write your own guitar effects!

Here's a great DIY build: a small keyboard imitates 4 NES controllers that are connected to the original NES running a NESK-1 synthesizer cartridge . Check out also this demo of the NESK-1:

Here's some Arduino powered synth magic for you. frauAngelico is a drum synth / sequencer, Standuino Pi is a drone synth and the microGranny a cool little granular sampler. Mix them up and you've got this:

The Seaboard is a very cool new instrument from ROLI . It is a soft version of the classical piano keyboard, with polyphonic pitch bend and vibrato added in to mix things up. Yes, you heard it right, you can pitch bend multiple keys in different directions at the same time!

The Mixtape Alpha is a $42 synth / sequencer smaller than a cassette tape. It is limited to chiptune style sounds, but is still very cool and very portable - you can easily take it anywhere with you. The schematics and source code are available to download, which makes it possible to even build your own.

In case you've somehow missed it, here's a really cool video clip of the ReacTable , which Rolling Stone magazine called the hot instrument of 2007. I had to include it here.

Every synth enthusiast must watch this: Moby going through his collection of synthesizers. The old drum synths get a lot of screen time. And Moby couldn't be more wrong when he ends the video by telling us he's not cool.

For all the Android users out there, here's a cool free app for you: Music Synthesizer by Raph Levien. It's an emulation of the legendary Yamaha DX7 . Via Music radar .

Here's an awesome demonstration of the robotic drum and percussion ensemble by Jazari ! Found this from the #1 circuit-bending page, getlofi.com .

Another Arduino made instrument: the Bleep Drum. See Bleep Labs' store for more info . A kit will cost you $60.

Here's a video demonstrating a breadboard based modular synthesizer by STEIM: This seems like a great way to create a VERY complex modular with minimal effort - no need to have kilograms of patch cables and banana jacks! For more info, see the webpage with documentation . Found from the circuit-bending and musical diy Google+ community .

This guy made some enhancements to his guitar with an Arduino... just awesome!!! Read more on the details at Hack A Day .

The Struthi-1 is an open-source hybrid digital/analog synthesizer, costing 140€.

Auduino is an open-source synthesizer on the Arduino platform. Making one costs you about $50. Here's one built with a stylus controller from a Gakken SX-150. Note that the delay and the back-up tracks are not coming from the Auduino. Auduino with a sequencer Here's a dry example - in this one all the audio is coming from the Auduino.
