I’ve constructed version 4.0 of the hardware. Notable features are: Pictures of the hardware and a schematic are below:

So after a bit of a hiatus I’m back working on this project. I completed the V3 hardware some time ago and recently I’ve made quite a bit of progress…

Although I haven’t posted recently ideas have been burbling around in my brain and I’ve purchased some parts for the 3.0 design. I’ve made the following hardware choices: Component Selection…

While 2.0 is a big improvement over 1.0, there’s still plenty of room for improvement. Here’s my goals for the next iteration: More compact form factor. I’d like to be…

This doesn’t have much to do with Trumpets, but I wanted to post this headphone amplifier I built. I’m not using it in a very demanding application (it’s for watching…

I’ve finally completed a second hardware platform. It now features: 128×64 Monochrome display Much more ergonomic design Here is a side view showing most of the mechanical elements: The bottom…

So to get USB midi working I needed an in-circuit programmer for an Arduino. It’s very easy to make one from an Arduino, I used a nano I had with…

UPDATE The USB Midi library now works out of the box.. Just include the library in your project, load the sketch, and your device will show up as a midi…

The first prototype works OK, but there are a couple things I’d like to address: – The form factor is pretty awkward. The push buttons don’t feel very much like…

There’s obviously been a gap in activity, but I’ve picked it back up lately and I wanted to finish off the documentation for the prototype I build and lay out…

The Beaglebone Black comes out of the box with a completely functional Debian installation. I used apt-get to install ecasound and some ladspa plugins and I was off and running.…

I mounted everything in a small equipment case: The Beaglebone Black, UCA202, and a powered USB hub are mounted to the top of the case using industrial strength velcro. To…

I already had a Mackie 0402VLZ4 mixer and a Beaglebone Black, so the only thing I needed was a way to get audio in and out of the BBB. The…

Here’s what it looks like put together: You can see the Arduino shield, with connections to 3 pushbuttons and the slider on the top of the box. The cable coming…

Here’s the schematic: The box in the middle is an Arduino Uno, which has everything we’ll need for this project. Breath Controller: The Gordophone blog has some great information on building…

We’ll have a breath controller and three valves just like the EVI; however, instead of the left hand manipulating a discrete control to select the harmonic, we’ll have a continuous…

Currently there is really only one design for a Midi Controller that emulates a valved wind instrument, namely the EVI (Electronic Valve Instrument) developed by Neil Steiner (see Patchman Music…
