Does it count if, combining the two, one could infer a musical scale[0] such as:

  Ada (ay-dah), Scala (ska-lah)

Bonus points for Latin aficionados:

  The word "scale" originates from the Latin scala,
  which literally means "ladder".

Every Good Boy…

Crazy how these two disciplines are so intertwined.

EDIT:

Seriously, though, what both music and fundamentally sound programming languages have in common is math. Elegantly defined versions of both are beautiful expressions of thought.

Yes, but the programming languages is much more well known.

Regardless, cool! This is the first project I'm aware of to have been written in Ada

Do you have any specific restrictions on what a 'project' means here? I have seen Ada used on an extensive scale in aerospace and defense projects, including a simple realtime OS.

Most of those projects are pretty locked down/closed, I just mean I can actually see the project to a reasonable degree.

Fair enough. And yes, it's such a shame that there aren't more public, especially FOSS, projects in Ada.

Been slowly learning Ada these last few weeks and I regret not having learnt it years ago...

This thing is great.

Now the Lumatone

I wish I had bought a few Axis-49 controllers when they were in production. They were a much more reasonable $500 at the time.

You might be interested in the Hexboard. Basically a mini-lumatone for ~$500; main downside is no velocity sensitivity.

I'm quite happy with mine, and play it with the Wicki-Hayden layout.

A Lumatone is $4250, though!

For programmers only :(

Does your tinnitus return when you're not wearing the Lyric devices (or when they're turned off, if that's possible)?

It returns when I turn them off. But this happens only for like 5 minutes every 3-4 months or so (ideally).
