Some interesting things I found recently:

# Arduino ant farm

Ants walking through IR gates manipulate the Auduino synth program. John spotted this at the RobotFest / Mid-Atlantic Mini Maker Faire. He writes:

I went to the RobotFest / Mid-Atlantic Mini Maker Faire yesterday. I saw this awesome project and thought you might like to put it on the blog. Basically it's an ant farm with optointerrupts. When the ants walk through the lightpath, they modify the audio output. The maker's name is Adam Franchino, and he was there with some of his classmates from the Maryland Institute College of Art (MICA) His website is adamfranchino.net.

# Copenhagen Institute of Interaction Design » Journey into Sound

“This is a Jouney into Sound” is a demo of the RHIFID speaker control system developed for the Physical Computing class. Using a combination of RFID technology, Processing and Arduino, the speakers work as location aware controllers, allowing the user to interact with music and the environment by moving the speakers around.

# Jordantron

Jordantron is a new iPad synth app that will include sounds by Jordan Rudess of Dream Theater.

Omenie in the comments:

The core sound generation is the Ellatron engine, and the same 'Toblerone' rotating keyboards have been retained – for now …

Inside it there’s quite a few changes, particularly trading off CPU burden against responsiveness – it’s become clear, particularly on the iPad, that it’s worth burning more CPU to get ultra-low latency for responsive playing, in Jordan’s hands this thing is *fast* and pretty amazing.

We are still shaking out details but the plan is to have different iPad and iPhone versions, slightly more voices in the iPad version as it supports apps with a bigger memory footprint than iPhone.

And yes, all new sounds, and unlike Ellatron all the sounds are stereo (and really immersive and immense) and have been pulled out of Jordan’s live rig, so these are authentic DT voices. So it’s not very much like a Mellotron at all! I think this one will turn out to be a must-have app for the DT fans, but the sounds are so damn PHAT that general synth hounds may end up picking up one of these to add to their arsenal.

I’m really pleased with how it’s shaping up.

# Four ways to use mid/side EQ

Kim Lajoie on mid/side EQ:

Several EQs now have a mid/side mode. This opens up a lot of possibilities, but can be difficult to use effectively. Instead of simply tweaking the sound or the range of the controls, mid/side mode completely changes how the EQ behaves and sets new rules for how it can be useful and effective.
It helps to stop thinking about mid/side EQ as an equaliser – but instead to think of it as a surgical frequency-focussed stereo width adjuster. It works best on complex stereo material, such as groups or the mix bus.

# Programmable Knex Piano-Playing Robot

I've always been a big fan of K'nex, ever since I was a little kid. Then, when I discovered this website, I felt like I had hit the jackpot. This is a "robot" that I built out of knex, it's designed to play the piano. This version can play up to a 16 note sequence in a 12 note range. I call it "Zeeanobot" (Zach's Piano Robot), corny, I know, but I couldn't think of a better name. I spent a lot of time on this, and I'm very proud of it, so please be nice. Just to be clear, I have not tried it on a real piano, I built it to play my Yamaha DGX-230. You may need to modify the design slightly to get it to work on real pianos or other keyboards.

# Sound Grain, a graphical interface where users can draw and edit trajectories to control granular sound synthesis modules. Sound Grain is written with Python and uses Csound as its audio engine. Csound 5 must be installed on the system to allow Sound Grain to run.

Audiostry

# Audiostry Synthesis

Audiostry V1.27 is made with Sync Modular. It's structure is based on Korg MS2000 but it is not an emulation. It has:

  • it's own single cycle waveforms for the DWGS (48 waves),
  • unison in polyphonic mode: each oscillator quadruples and is internally modulated by a slow LFO.
  • dual filters.
  • 2 more patch bays.
  • 16 step modulation sequencer with 2 more lines (total of 5) and 39 parameter destinations.
  • 143 finely edited presets.
  • 16 voices by default but can be changed by user within Sync Modular. You need Sync Modular to run it.

Sync Modular has been discontinued but it is now free. Get it here: http://www.syncmodular.com/
