Back soon.

That Nyatiti sounds great! Reminds me of some tongue drum designs.

@Gravitas Why so complicated? My patch example works, you only have to extend it to use more LEDs and do that for each frequency band. The reason I've used Graphic Shapers is that you can adjust the correct note numbers intuitively for any pad controller that supports illuminating pads via note numbers instead of having to look them up in some technical documentation.

... What I haven't quite figured out yet is the amplitude per band.
and how to display that using only midi notes.

That's exactly what my patch does, just add a note gen for every LED and merge the MIDI messages before sending them to the Launchpad.

A little side note.
The LP X will react natively to midi notes but it won't react to cc messages.

Like my older LP Mini 😊

Ah yes, I've tried the Mozaic patches from Soundtempletgat can be found on patchstorage.
Requires slight modifications for my needs but it is quite fun to play with.

I still don't see the need for any scripting here...
I've tried it with only 4 LEDs and the VU meter works as expected.

@wim Where did you get your encoder from? Looks sweet.
And how does the rotary encoder feel? Easy and smooth to turn?

https://www.adafruit.com/product/5001 - the encoders are in stock, but I bought the last of the PCBs that make it easier to wire them up. I'm thinking I would have been better off with a different breakout (https://www.adafruit.com/product/4991) because these things take a lot of GPIO pins. That other breakout lets you wire up to 8 of them up over a single I2C bus with no soldering needed. So for now it'll be just some limited experiments until I talk myself into the next order of still stuff more I really don't need.

I like the feel of the encoder as much as most others I've tried. Like the rest, they're just a little bit more clicky than I'd prefer. But that's just based on the first touch out of the package, not wired up or even mounted to a breadboard.

Cool, thanks @wim!
Exactly what I wanted to know.

Now thinking about how I could re-use an old 3.5" hard drive motor with its beautiful aluminum head as a rotary encoder. Shouldn't a 3-wire brushless motor send signals that could be translated into rotational information?

Edit: Of course I wasn't the first one to think of it

I'm really, really, really glad I don't have a Launchpad right about now so I can't get sucked into this. 😂😎

I can arrange for that….
You dunno how much it would help me with that abomination of a script I sent you before.

Actually, imma upgrade that opinion after another look. This encoder feels great. It's not too clicky at all and running a finger around a circle is more satisfying than twisting a knob. Really fun, and looks great too. If only the nifty Adafruit LED rings weren't just a tiny bit too small ...

@wim Hmmm - If space isn't an issue...

And this one looks even better, with proper circuitry on board already:

If we are building hardware controllers….do tell do tell

Namely because it shows that we all think differently when problem solving and/or
faced with a challenge which is especially useful for other users.
What’s important isn’t the result,
what’s important is journey to the
desired result.

I still don't see the need for any scripting here...

I do because I need to learn scripting
which I’m going to use to replace
some of the functions that
I’ve used in my earlier Drambo projects.

I’ll try your patch example
again a little later on.

Well, this thread went too deep for me. Haha. Glad I started it, though!

LoL. This is just to help you mate!

Oh, I know! Haha. I'm glad I could spark such exploration and discussion amongst the coding heads here. Can't wait to see what comes of it all! You are all fantastic.

Thank you.

It's based upon an eight stringed instrument tuned to a pentatonic scale
also called a ,'lyra', one of the earliest of harp designs.
It and other variations can be found all over Western Africa.

The instrument goes back approximately 5000 years.

It was my former mentors main instrument.
The samples that I used for the notes are also from his original nyatiti.

@Gravitas , this should be easier with a combo of Drambo and StreamByter. Let Drambo do the signal processing and send data to StreamByter in the form of CCs. Then let SB convert those numbers into note on or off as needed. Use an array to remember which pads are lit, and send notes to alter the lights as needed. This is much easier to do in SB, since it can send note on and off messages more or less at random, i.e. not musically, while Drambo is locked in to being musical.

I don't have enough knowledge in regards to both Streambyter and Mozaic.
I use Streambyter to block messages I don't need and to monitor midi.
That's why I'm currently reading the Mozaic manual,
I only got Mozaic a couple of weeks ago.
I'm a total noob.

That's a good idea though.
Using cc's from the initial part of the path and then converting them into midi notes.

Basically the layout for the LPX is a workable map.
It is doable, I simply have to not think about it.
If I think about, it won't happen.

The main reason why I'm able to do so much
in Drambo is because I don't need to code.

It looks like the other proposed solutions, using thresholds in Drambo or sending Sysex to initialize LPX, may be nicer, but I followed through with a StreamByter script that should meet your original requirement. It converts CCs into Note On and Off messages to control lights in a column. You might find it interesting as a coding example, anyway.

Nicely done.

I’ll give it a try a little later on.

Thank you.
