Free Multisample: Electron ECHO Mini Piano

When I was a kid, a bunch of my friends had the same little musical toy. It was about a quarter of an inch thick, about the size of a smartphone; it featured a row of rubbery buttons which, when pressed, would play different notes on a scale. It was, essentially, a tiny, very primitive synthesizer.

It was the oddest little device: it could only play one note at a time, had no ‘Off’ switch, and it came in a little sort of wallet thing with a cover that you could close when you weren’t using it. I never saw one on sale at a toy shop, either. It seemed to be something that only existed at my friends’ houses.

Well, last year, I did a bit of research. It turns out that the toy was called the Echo Electron, although it was actually sold under a variety of names. The reason that I never saw one in a toy store is that they were actually sold via mailorder. Go figure.

Even stranger is that it seems they’re still being made, although the packaging has changed slightly since the 80s. Needless to say, I had one shipped from China for the princely sum of $1.99. Here’s what it looks like:

It sounds exactly like I remembered: the notes all lasted the same amount of time, and the pitch wasn’t 100% constant. It would start one one note and slowly slide down a half step as it got softer and softer. As an instrument, it’s terrible. Ostensibly, the notes are supposed to form a major scale, but the pitches drift so terribly from one note to the next that by the time you reach the top of the scale, you are actually in a different key from where you were at the bottom.

Anyway, I opened it up, and plugged the little speaker wires directly into the audio jack of my sound card and recorded. Now, I’ve made multisamples (SFZ, Ableton 9.7, Kontakt 5.6) for those who wish to use them with their music software. I’ve done my best to tune the instrument so that it is in key, although that’s very difficult for an instrument that doesn’t hold its pitch (you may find yourself adjusting some of the samples by hand as needed.) What else? I’ve added polyphony, and I’ve also expended the key range so that you are not limited to the major scale that the actual instrument plays.

OK. That’s it. Enjoy!

  1. hola seria expectacular que dieras los pasos para comprar uno tal como tu lo hiciste. gracias.

  2. You say they still make and sell these, but don’t mention who sells them. I’d love to get a mini or two for my children, what site do I go to?

  3. Hi Mary! So the website where I bought mine seems to have vanished. I’ve tracked down the manufacturer (Kwong Fei) here, but I can’t figure out how to order them directly.

  4. Actually, when I was a kid, they were sold in Walmart . I know, because that’s where I first saw them and I begged my mom for one, not knowing my Grandma had already bought 1 for me and my 3 siblings as a stocking extra for Christmas . So, that year, I got 2 of them .

  5. The coolest musical toy from the 1980’s is the Rose Petal Place Omnichord Auto Harp . Look it up on Youtube, there’s a 1 minute clip there showing what all it can do and it’s AWESOME !

  6. Surprisingly I can’t find it anywhere to buy. BTW the model seems to be Kwong Fei KT-601 and not HC-02.
    If anyone finds where to buy one new let us know!
