- I mentioned this one a couple of weeks ago and the boards arrived today. This is my first go at a Pi hat, it's for the Pi Zero and gives the buttons, screen and DAC needed to use the MT32Pi software with a MIDI controller like MIDIKalimba
I've now listed this hat here:

(Note that I also make a hat for the full-size Raspberry Pi, Pi3 updwards).
Instruments used:
MIDIKalimba: peacockmedia.software/kalimba
e-ther: peacockmedia.software/e-ther - เพลง
👍👍👍👍👍
That is awesome!!! I love how small it is and how much power it has for the size. Great design. When you talked about plugging it into E-ther, I was picturing you getting frustrated every time it defaulted back to the piano sound. 🤣 That would annoy me, great little hack to change the program on startup.
That's a feature that e-ther is about to inherit from MIDIKalimba. I'd not envisioned using e-ther this way (it has its own audio after all) but it does work very well and gives you some fantastic sounds in a portable device. Without sending a program change, though, I'm not sure that there is any way to change the instrument.
Looking great - that is a really neat board.
Looking at what you have, I'm pretty sure you could also use it for a MiniDexed if you wanted a DX7 kalimba rather than an MT-32 :)
If you use your Zero 2W then you get 8 DX7 tone generators, but it would work with an original Zero if you were happy with a single tone generator.
Thanks Kevin. I thought this might be a stepping stone to a cleaner surface-mount design, but after building this (using nice domed soldering 😎) I'm really pleased with how it looks.
I hadn't thought as far as other software that I could run on the pi but I'm totally up for trying the DX sounds (I hadn't realised that Dexed was a play on DX - D'oh!)
Also - I've just realised that the electrolytic (and the other caps for that matter) could totally go on the underside of the board (I might reverse that tomorrow) for an even cleaner look. I see this going in a 3D printed case anyway.
nice how you can do so much with a bunch of electronics that fit on the palm of your hand! you should the team up with someone who has a 3D printer to make a casing then you could bring them anywhere in your jacket pocket and have fun
also if your at it could you also make it possible to send CC instead of PC with the e-theremin?
Thank you! People do have this concern with e-ther (being able to carry it around without damaging it). They're pretty robust, being made of copper-clad fibreglass. But am thinking about a super-robust version of e-ther housed in a metal guitar-pedal type case. The e-ther already has a CC mode. it suppresses the 'note on / off' messages leaving just expression or modwheel on the left hand (on my to-do list is to add filter cutoff to that list) and pitch bend on the right. If this isn't what you meant, please explain in more detail
Where can I learn more about these boards and this tech in general?
I'm not really sure where to point you. Do you mean the MT32Pi side or my midi controllers?
@@midi_in the MT32 and all it’s friends 😜
@@midi_in is there an overarching term to describe the Raspberry/Arduino/MT32 little computer tech?
@@midi_in it's ok I have just had a frantic Google session and think I'm up to speed now :)
@@AntonyNorthcutt Excellent! if it's the MT32Pi stuff, then we're into open-source territory there but Dale Winham's excellent software is extremely well documented.
Why is it called a hat?
It's a convention, I'm not sure why, possibly because it sits on top of the Raspberry Pi. The Pi has a long connector, lots of boards exist which plug into that, sit on top of the Pi and add functionality (in this case a screen, DAC and buttons) and they're called hats.
I just had to look it up. Apparently HAT is an acronym standing for 'hardware attached on top' . Sounds like it might be a backronym but there we go. Every day's a school day.
