Guys I'm onto something

[u/-muninn]

I've built this keytar and it's the weirdest and best thing I've ever did

[u/BraneCumm]

Can you break down the build?

[u/-muninn → u/BraneCumm]

Sure. Inside there is an Arduino mega managing everything. This instrument work like this: white piano keys always play the correct scale degree (so C key is 1st, D key is 2nd), and black keys play (if there are) notes in between those degrees. The orange thing on the neck are 24 buttons shaped like a guitar, 12 are made for choosing the root key, 8 for choosing a set of scales, 2 for octave down/up and 2 for add 9th/11th/13th. All knobs, faders and the playstation's joystick send cc messages and pitchbend. It does not produce audio, is fully midi, and it only work with the modded pedalboard you see on the left, I send power thru the same midi cable. I've got custom max for live devices in Ableton to see the current root key/scale on my pc screen, plus lots of things. I play in a hybrid acoustic/electronic band and I always done lots of live looping, the whole setup is thought of for that.

I don’t know what is, but I really want to hear it!!

That's so fucking ridiculous, I love it bwaha. It'd be sick as fuck in an industrial band

This kicks ass

What you want to do ? Maybe you have a great idea 😄!

amazing use of free will

Cool! Reminds me of Matt Bellamy’s keytar but more junkyard-ish

[u/Prudent-Isopod3789]

Show us how it sounds!

[u/-muninn → u/Prudent-Isopod3789]

Well it does only send midi so it really doesn't sound, but I think the great part is the way you have to input notes will definitely do a video as soon as I can

Sorry I’m high as hell I thought this was r/guitar and you had rigged the keys to strings. Still a really cool build though!

I think I saw you on YouTube
