This toy keyboard is being used to play music on an NES. As you probably already know, the hardware inside those original controllers was dead simple. They’re just a parallel to serial shift register that reads from all of the keys. To get this keyboard up and running [heavyw8bit] simply mounted eight chips inside the gutted toy, connecting two of them to the keyboard keys, and the rest to the array of push buttons he added to the right.
So what’s the point of using this as a quadruple game controller? Are you expecting to see what a full speed-run of Contra looks like using this as the controls? That’s not the point at all. This becomes a musician-friendly frontend for the NES synthesizer ROM called NESK-1. [heavyw8bit] wrote the game/program in order to allow you to use the original console hardware to play all of the sounds you know and love. Our favorite is the arpeggio example heard at about 2:35 into the clip after the break.

We take it for granted today that a lot of the music we hear includes synthesized instruments and sounds. But looking all the way back to 1983 for this Discovering Electronic Music video series provides a glimpse of the humble beginnings of the technology. The first five minutes of part one may annoy your aurally, but it’s worth it as that’s the point at which we get into sound generation using equipment like that seen above. All three parts in the series are embedded below; about twenty minutes of video in total.
Mixer boards and other control interfaces used today still have a large area of real estate devoted to knobs and adjustments. But they also include a ton of software processing options which weren’t available until computers became both affordable and ubiquitous. What’s shown in the video is a set of hardware interfaces that process signals from oscillators or alter recorded sound. We’ve spent a lot of time marveling about software defined radio and how it’s making RF hacking accessible to the masses. But who here hasn’t done at least a bit of tinkering in electronic music using any of the myriad of audio software? Would you have done that if you needed to build your own envelope and filter circuitry?

[themonkeybars] recently uploaded a time-lapse video of his DIY synthesizer build. First off the video itself is a pretty neat hack. An iPhone time-lapse app was used to capture one frame every 5 seconds. By the time the build was complete, approximately 46,000 frames had been snapped. This boiled down to over 43 minutes of youtube footage. [themonkeybars] didn’t work full time on the project, so the video covers about a year’s worth of work which we think makes it even cooler. The synth is also featured in much of the video’s soundtrack.
The synthesizer itself would be classified as an analog modular synth, a type we’ve seen before. Modular synthesizers are one of the earlier forms of electronic music. The synthesizer is composed of discrete modules such as oscillators, modulators, and filters. The modules may be housed in the same box, but they are not internally connected. All connections are made via front panel patch cables. This is where the term “Patch” came from. Continue reading “Time-lapse synthesizer build will blow your mind”
This pair of dongles is a fun way to get your feet wet working with MIDI hardware. They’re called MIDIvampire-I and MIDIvampire-II. Just plug one end into your MIDI-ready instrument and the other into a pair of speakers and you’re off and running. Mark I is a polyphonic synth, and Mark II is a drum machine, but both use basically the same hardware which you may already have on hand.
The single chip on each board is an ATmega328 often found anchoring Arduino boards. The other silicon component is an S1112B30MC voltage regulator. The rest of the components are passives, with MIDI and headphone jacks for connectivity. They’re selling these if you want the easy way out, but we thought we’d bring them to your attention in case you needed a breadboarding project this weekend. The firmware, BOM, schematic, and board artwork are all available on the Wiki pages linked in the articles above. After the break you can see a couple of demo videos which walk through all of the features.

For all the cool things the Raspberry Pi, BeagleBone, and other low-power Linux boards can do, there’s one thing we haven’t seen much of: creating music with software synthesizers. Yes, soft synths have been around for ages now, but compiling them for these ARM boards is something we haven’t seen much of (to say nothing of the Linux audio system). Luckily, [Paul] and [Trev] have put together a tutorial for making synthesizers on these small Linux boards using Csound, the premier audio programming language for Linux.
[Paul] and [Trev] have already put together a few Csound instruments that include a Vangelis-inspired synth, a Lorenz Strange Attractor FM synth, a drum machine, and a classic monophonic style synth. All these instruments are ready to play on a Raspi or BeagleBone and we’re sure we’ll see a few more applications of this great tool for creating musical instruments as more musicians are turned onto these small Linux boards.
MIDI guitars have been around since the 80s, and nearly without exception they are designed as direct, one-to-one copies of their acoustic and electric brethren. [Michael] has been working on turning this convention on its head with the Misa Tri-Bass, a MIDI guitar designed to be the perfect guitar-shaped synthesizer interface.
The tri-bass doesn’t produce any sound itself; instead, it’s a polyphonic MIDI controller with three channels controlled by three ribbon controllers on the neck. The body contains a huge touch screen divided into four MIDI channels, essentially turning this guitar into an instrument designed for electronic music first, and not an acoustic instrument kludged into filling an electronic role.
Unlike a whole lot of other digital guitar-shaped MIDI controllers, the tri-bass is actually made out of wood. Yes, the neck is made out of maple (inlaid with the three ribbon controllers, of course), and the body comes directly from a tree, with the styling inspired by a forgotten retro-modern design. It’s an impressive piece of kit, and we can’t wait to see [Michael]’s handiwork in the hands of digital guitarists the world over.
You can check out a video of [Michael] rockin out below.

Building an analog synth is a challenge, but with the [Tymkrs] protosynth, it’s easier than ever. It’s a 25-key keyboard attached to a stack of solderless breadboards to make analog synth prototyping a snap.
Earlier, [Tymkrs] acquired a whole bunch of solderless breadboards and decided to put them to use by making a component-level modular synth. The earlier incarnation tied each key on the keyboard to a few wires behind the breadboard and tied them in to a shift register so they could be read with a Propeller dev board loaded up with a Commodore SID emulator. The new version keeps the very clean through-the-back keyboard connector, but this time the [Tymkrs] are adding a few more components that add a sequencer setup and a rotary encoder.
The eventual goal for this really cool breadboard synth is to explore the world of Moogs, Arps, and other analog synths easily on a breadbaord. The [Tymkrs] have already put together a breadboard-compatible low pass and high pass filter. While there’s still a lot of work to be done to make an analog synth a reality, the [Tymkrs] are off to a great start.
