Able to play Chords

Hi! I firstly wanted to say I have been looking forward to Stella for a while and can't wait to hear more updates!


I just had the idea if it was able to play chords by pushing a button that your left hand can easily reach like a button to tell the instrument to play a major chord or a different button for a minor chord, 7th chords and diminished chords. of course there is still more types of chords but I think if the instrument had the option of 4 buttons play a major chord, minor chord, 7th or diminished it it could be really innovative with just that much. Like you could be soloing and you want to hold a note out but make it a chord so what ever note you play could be the root and you press a button and the trumpet will also sou…

Haha, and I'm looking forward to getting them in peoples' hands. Still got a thread running on this but my master's thesis is taking heavy priority until I graduate next May.

Valve Trombone Stella

I'm looking to make my own Stella but i have no idea of how to start this. I basically have no knowledge of coding or assembling hardware like this. Not only am I looking to make one for myself but I also would like for it to work with my trombone mouthpiece as well. Since I dont really understand how the code works would it still work with me buzzing something like an octave lower than a trumpeter would normally? Some

help on how to get started would be greatly appreciated.

Hey Jerry, glad to hear you're interested.


So as of now, Stella won't work very well with a trombone or tuba mouthpiece. This is because the notes that are buzzed are lower than those made with a trumpet mouthpiece. However, this functionality might be possible in the future! I'll definitely keep you updated on this forum.


If you're interested in the technical details, I can explain a little. Essentially, the lower the note, or frequency, that is buzzed, the longer Stella will take to identify which note it is. This is because a lower note has a longer wavelength, meaning it takes more time to capture one full wavelength of the note. Anything more than 10 milliseconds of delay will be distracting to a musician, and trombone/tuba mouthpieces produce notes that are low enough to produce that kind of delay.


I believe there's a way around this, by detecting the higher frequency harmonics of a note, rather than just the fundamental (or lowest frequency) of the note. However, I haven't found the time to look into this!


Til next time,


David
