Quantise Pulse Period Timing to MIDI Note Numbers

My top secret guitar pedal is NOT a guitar synth, but it does output MIDI notes...

Well, it will output MIDI notes, velocity and channel data when it's actually developed, but it's not a synth. It's still in a crude, analog prototype iteration right now. No, it's not a guitar synth, but the idea is audacious and groundbreaking.

12 freakin' lines of code

Nope. Still not telling.

There's loads of stuff it already does, combining more than just guitar, to create... Nah, still not telling! Cruel, aren't I? Be patient.

However, tonight, I can proudly say that MIDI note numbers can be "quantised" from period timing. Schmidtt trigger, edge detection, the pulseIn() function, a lookup table... IN 12 FREAKIN' LINES OF CODE! Mathematically, elegantly et voila! MIDI notes can be made to happen. In a sim, so far. On the command line. But those 12 lines of code will actually cut down to about 8, in an actual "pedal." Yeah, there's heaps else to do, too, but this turned out to be way simpler than I saw it in my head.

That is all.

For now, at least.

Because I'm That Kind of Crazy

Something I've always been fascinated with are those people who build wooden bikes and trikes. It's something I've wanted to do for a while, too. So, while I wait for other projects' parts to arrive, plug on with yet other projects and generally mess about while I wait for reliable weather to weld my lean steer, steel trike, I decided to design an Ackerman steering plywood trike. This one... The core of this baby is the curved crossmember, or the "wing", as I call it. This render doesn't yet have its brace developed, and the main frame is still the crude draft and needs shaping, but you can see the idea taking shape. The curvature of the wing gives 12 degrees at the steerer head hole centres. It also allows for a single piece wing without having to angle two sides, having a weak point in the middle or having to drill complex angle in flat pieces of wood. All of the correct angls are developed in the shape of the spar and the curvature of the wing. Ot

I Am a Man of Many Projects

Some might argue, "Too many!" As individuals, we are the sum of our ideas, that equation for me results in "technological Trotskyite with a twist." Endless revolution is consensus anarchy in loose collectives, for example the best of the best of free, free, open-source software. Such a group works tirelessly to create an app for community benefit, rewarding significant contributors with "commit privileges" on the version manager where the project is maintained, the collective of contributors having voting rights on who is doing well as a maintainer. The titles are not very anarchistic, but they actually don't have to have any meaning other than the role a person chooses to take on the project. If a fee is charged for the app, the maintainers and regular contributors, get an equal share of the profits. I just recently established a project like this, no bites yet, I've barely the skill to flesh out "HelloWorld.cpp" yet, but I'm offerin

Meanwhile, Developing a MIDI, Tap-Tempo, Master-Clock Pedal...

Image
Kind of the other inspiration for the Robo-Drums, I've also been thinking about a MIDI Master Clock that started with the WAY TOO AMBITIOUS idea of a central 2-way, DINsync-MIDI-And-Back Master Clock, that I thought would be cool to add tap-tempo to. (Draws HUGE breath after that mouthful!) I dug out one of my Wio Terminal micros, promptly killed it on a distraction, dug out the other and started developing this concept. The left and centre buttons will probably have a gang reserved for straight switching of start/stop and pattern-select, as well as for triggering to Wio Term to do MIDI.sendStart/MIDI.sendStop (left) and MIDI.programChange. (Center.) The right button will be the tap-tempo button. The toggle switches will select normally-open/closed modes for the analogue button-out function. On the tap tempo stuff, I got to thinking about " Kilroy's Blues " •1 , a song I wrote back in the mid "noughties," and how it would be cool to "pedal"
