  Challengers! The judging deadline has now passed - thank you so much to everyone who took part!   If you're not finished yet, I'd still love to be able to follow the progress on your amazing projects. My project, LaserScope Music is also not yet complete - but you'll be able to continue to follow it here on the element14 Community, as well as at Music Tech Fest in Berlin.   Speaking of Music Tech Fest... Ben Heck is going to be there with us! http://musictechfest.net/ben-heck ...
Tim Berce’s Fret Friend makes it easier to learn to play the guitar by allowing players to mark the various chord locations. (via Fret Friend)   Playing the guitar is easy, especially if your last name is Hendrix, Halen or Vaughan but for the rest of us it takes a considerable amount of time and practice along with a boatload of frustration, especially for beginners. The problem, at least for some of us, lies in ‘communication’- specifically the communication between the ...
Oh yeah, it works! I hooked the suit up to PureData and after some tweaking it worked! I made some small tests just to try it out, and it's really a lot of fun, playing around with this! I am very eager to get to know the suit and tweak it so that it feels more natural to move with it and make some sweet sounds!   Ideally, if my kit would have arrived, this would have been hooked up to a BBB with a speaker and a battery, so that the suit would be standalone (currently I have it connected ...
  I coded the Teensy to receive all the inputs (I decided to go for 6 inputs for this initial prototype), and gave them different control numbers. In the beginning I didn't really get what these control numbers meant, but I figured it out quickly as soon as I launched PD and I hooked it up to the patch.   There will still be some calibration left to do, as I still have to make some details to the base suit to make it more snug so it can adapt to the stretch sensors, but this is reall ...
Then it was the thing about hooking everything up! This was really more difficult than I had imagined, but it all worked out well eventually!   I spent some time soldering and tinkering to get everything to connect properly, after I had made the remaining stretch sensors. It was kind of scary soldering stuff so close to the fabric, but no mishaps and everything flowed smoothly! Then I connected everything to a protoboard onto which I had attached the Teensy, and now I had the circuit ...
Today at our local hackerspace I did some calibration of the stretch sensor prototype I had finished. I was assisted by some other people who hang around here, who helped me out a bit with ideas on how to adapt the code in the best possible way.   I adapted the teensy code through adding some mathematics, and used a different resistor to get the values I wanted. By using another resistor I could also work out the issue of how much power the Teensy can output, and thus I can add more str ...
There we go! I've finished up creating the base of the suit, onto which I will add stretch sensors and the electronics! It took some time to finish it up (a lot of stuff happened in my life as well these past few days), but now it's done!   The final design of the suit didn't quite turn out as I would have liked it, but I felt I had to let go of the perfectionist attitude due to the time constraint. I chose to go with an open back to create a more revealing look for it, while still keeping ...
Firstly, I'd like to say that it has been great to take part in this challenge. Personally, it has been a great opportunity to return to making stuff after months of no hardware projects. Also, it has been very helpful to get myself with the Bela platform and BeagleBone Black, and this will be incredibly useful for future projects. And if that wasn't enough, I have made huge progress on Kazumi, which already had a past before this challenge and now has a future beyond it. That said, I am aware m ...
This entry shows how Kazumi can be used to play drum machine sounds.   The responsiveness of the instrument, thanks to the ultra-low latency Bela platform, makes it perfect for percussive instruments. I wanted to try this with some classic drum machine sounds.   The Pure Data patch uses the excitation from the piezos to trigger the drum samples, which are stored in arrays. This is one of the subpatches: Here is a video of how this sounds at the moment(I'm an amazing drummer as you ...
As Music Tech Design challenge comes to a close , here is blog post which gives you an overview of the DIY Drum kit and a couple of versions that I have been able to make using BeagleBone Black , a couple of capacitive touch sensors based on the MPR121 and 3D printing.   It has been hectic and a lot of fun working with the BeagleBone black using python, and a big thanks to element14 for sending me the awesome kit.   Which one will you make ? Here are a few of versions of the 3D printe ...
This post outlines the current MIDI compatibility, and shows how the new prototype being played for the first time.   Unfortunately, lots of stuff has gone wrong these past few days and I have had to redo a lot of the electronics. One of the MPR121 boards has blown, a couple of the piezo leads snapped off, even the speaker has blown! Basically, not what you want on the day of the deadline, but hey, we're getting there   The Bela platform currently supports MIDI in over USB. Somethin ...
PlectralEFFECTS - Final Notes    I have had a busy couple of weeks, and unfortunately the project has been on hold.  I have been busy with getting our family home ready to go on the market.   I did however complete the implementation of continuous controllers, and obtained my main goal of the project to control the effect / envelopes from the plectrum.   Please see the following video for the demonstration purpose :       The main challenge fo ...
So this is my 18th and final blogpost for my music tech design challenge project, and for it I have created three new videos talking about and demoing the end result of the project: A specification overview video, outlining all the features of the synth as well as briefly discussing the overall development of it and how it works A complete walkthrough video, demoing in detail each control and parameter of the synthesiser A video on how the device can be used as a MIDI controller   I've a ...
I have almost finished the build of Kazumi. All the pad cables are done and connected. I've made a little circuitboard to attach to the analog input sockets on the Bela cape, which contains the circuit for all 7 piezos. I have cut some side panels for the on/off buttons, audio in/out, etc. I still need to solder some cables to the master volume potentiometer and the rotary encoders. (I'm testing them with a breadboard first today)   The idea for having detachable side panels is to allo ...
When constructing the upper body of the suit, I got into a creative flow which gave me entirely new ideas on how to construct the suit. As I was tinkering with how to put the pieces together I just got a vision which really took the design to a new level!           Experimenting with putting together a full body suit   Before, I was planning on making a full body suit, but now I figured I could make a two piece suit which would suit my sty ...
