Midi Trumpet

HW Design (Electrical)

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 a breath controller. I used the Freescale MPVZ4006GW7U, which is a through-hole part. I wanted to put the part on a prototype shield and I didn’t want solder a surface mount part; however after putting everything together I’m not sure this was a good decision, the arduino plus the shield plus… Read More »HW Design (Electrical)

So what’s this great new idea

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 control that represents the note we want to play. To determine which note is being played, we look at all the possible notes for the current valve combination and find the one that’s closest to the current value of the discrete control. To give a little more detail, here are… Read More »So what’s this great new idea

Why bother with a new concept for a Midi Trumpet Controller?

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 for all kinds of information). The more recent Morrison Digital Trumpet  uses pretty much the same principal of operation. In both cases there are three valves like a trumpet and some kind of system for selecting the harmonic. This is a bit different than a real trumpet. For example, if… Read More »Why bother with a new concept for a Midi Trumpet Controller?
