I bought a Vangoa MiDi EWI and thought I'd look at what's inside!
I may use the housing for my own wind synthesizer project.

Thanks for taking this apart so I don't have to! A useful bit of side-learning is that it looks as though it could be possible to clean the two air tubes with a pipe cleaner (as in a smoking pipe).

You're welcome. Yes, I suppose you could.

지난 몇 개월동안 이 악기를 사용해보았습니다. 악기의 장점은 몇 개 안되는 사운드이지만 음질이 꽤 괜찮습니다. 단점은 운지법이 너무 단순하기 때문에 다양한 기법의 연주가 어려웠습니다. 특히 Bb key 가 없는 것, 색소폰의 side key를 대체할 한 두개의 키가 있었다면 하는 아쉬움이 있습니다. 이 악기를 설계한 사람이 실제 악기를 다뤄본 적이 없는 것 같습니다. 단순히 악보에 표시되는 모든 반음계를 낼 수 있는 한가지 방법만 제공하면 된다고 생각한 것 같습니다. 색소폰이나 플르트, 클라리넷 같은 악기의 다양한 보조키는 오렌 세월동안 연주자들의 필요에 의해 개량되고 발명되어진 것들이라는 것을 생각하지 못한 것 같습니다. 또 한가지 아쉬움은 총 3옥타브의 음역을 제공하지만 3번째 옥타브 위에 C ~ G 까지의 음이 없다는 것이 연주가 가능한 곡의 폭을 대폭 줄여주는 것 같습니다. 나는 몇가지 튜닝을 통해 사이드키를 대체할 방법을 마련하여 아쉬운대로 책상위에 두고 수시로 스케일 연습을 하는데 활용합니다. 그리고 이 악기는 아주 약한 바람으로 소리가 나기 때문에 충분히 폐안에 있는 호흡을 연주 중 밖으로 배출하지 못하여 마치 오보에를 연주하는 것 처럼 숨이게 차오릅니다. 그래서 배기 파이프를 아주 짧게 절단하여 스피커 옆에 구멍을 내고 그 쪽으로 배출 시켰습니다. 이 전 보다 훨씬 편안하게 연주가 가능했습니다.

귀하의 의견에 감사드립니다. 귀하의 수정 사항이 흥미롭습니다. 나는 또한 사이드 Bb 키를 화나게했습니다. 왼쪽 새끼손가락 키 중 하나에 구리 테이프를 붙였습니다. 그리고 분해해 보니 패드가 연결되지 않은 부분이 있는 것을 발견했습니다. 음을 연주하면서 터치하면 비브라토가 발생해요! 아쉽게도 외부와 연결이 되어있지 않더군요. (Google 번역을 사용하여 이 글을 썼으니 이해해 주시기 바랍니다.)

I like your thumb holder. Where did you get it? I just bought this EWI. LOVE IT! Thanks for this "in-sightful " video!!

@windysynth 11 ай бұрын

Thanks! I got the metal hook at Home Depot. It's just a hook you might use for hanging your keys or whatever. I just bent it a little. Another easy mod is to add a small piece of copper tape from the first left pinky key over to just above the right hand. This gives you a side Bb key. But don't use too much tape or it will be like you are always touching that key.

@windysynth great idea! 👍🏼 Thanks!! I also play the Native American flute, so I might try the thumb holder idea there too. Thank goodness for velcro tape!!

I have a clone of this, it has 11 touch keys but the topmost seems to do nothing. I too hoped to use it as a base for my own instrument with Arduino, but now it seems unrealistic to achieve something reasonable in such a small case and with that special i2c chip that is not supported by Arduino. So, I'm still looking for a versatile and small MIDI controller. I wish NuRAD was cheaper and with shorter waiting queues. I would even gladly accept a NuRAD kit that I could assemble myself if that made it more available and cheaper. I now have Aerophone AE-05 but it has some annoying limitations that I don't like.

Yeah, if I want to use this housing, I'm pretty much going to need to make new pcbs. I can reuse the breath sensor and the metal keys, but I'd end up 3d printing my own housing anyway. Also I got the NuRAD and NuEVI so I could tinker with the code--and I love them, but yeah, hard to get and you do pay a premium, but worth it with all the sensors they have. Make sure you stay updated on the Berglund instruments fb page if you are in the queue for one, and check your email spam folder for some from them. They are pretty responsive on fb.

the touch sensor chip is a holtek bs83b16a -it appears to be i2c but there is a wakeup or interrupt line in the 6 core ribbon cable going to P7 of the chip. Good luck finding a library for the Holtek. I tried the i2c scanner in arduino ide but nothing..

Thanks for the info. It looks like it actually has 13 touch sensors. I noticed after making the video that ther is one pad on the board not connected to the outside. I touched it while playing and it adds a vibrato. I was going to add a metal button and attach it, but I broke the board doing another mod--Doh!! Anyway, too bad there isn't an arduino driver for this chip.

Thank you for this video. I have the similar instrument, without silver key tops, simply branded MIDI EWI . I wonder if it is possible to make a hardwire MIDI out. Also how to mute the "Bluetooth Connection" audio.

@windysynth 7 ай бұрын

It doesn't sound like yours is the one from Vangoa, but if the circuitry other than the fingering pads is similar, then it doesn't have any way to get to the midi signal other than with the USB connection. So you'll need to hook it to some sort of USB midi host like a. computer. As to muting the audio, can you just turn down the internal audio level all the way?

@grahammoore6936 7 ай бұрын

Thanks I'll give it a go. I didn't realise the power socket could also send midi. Although in Chinese this video looks interesting as it appears to show an extension of the octave and sharp/flat keys ? kzbin.info/www/bejne/aWPUpWuLmbR7jqcfeature=shared

I got one of these listening through headphones the trumpet etc sounds great but with playing with out headphones the built-in speaker on device making sound not as good do you know how to amplify the device Ta

@windysynth 4 ай бұрын

Yeah, the internal speaker is not great--OK for practicing i guess. Just run a 3.5mm stereo audio cable from the headphone jack to an amplifier with a stereo input. A lot of Bluetooth speakers have am "Aux" in you can use.
