Gecho is a collaborative lizard

Kickstarter has been fulfilled, shops open and recently sold out as I've ran out of certain material. There are still some boards left so the plan is to re-open early next year.

This allows me to get back to expanding the firmware for the time being. The list is quite long, but one feature that you guys were asking about a lot was syncing with other devices. I'm starting experimenting with my humble but growing collection of prevailingly DIY synths, most of them have some kind of clock input or output.

After Kickstarter has been fulfilled, here is your chance to grab one of the remaining units!

If you feel like putting some effort in, there is similar spectrum of DIY options as it was in KS campaign. Also, for hard-core soldering fans, a new type of DIY kit is available, consisting of bare PCB board and SMD/THT elements. By constructing it, you will earn the rank of "Master Gechologist". The advantage of this kit (apart from lots of fun) is option to mount LEDs in any colour scheme you like, and choose between black or dark turquoise-blue circuit board.

Raw boxes (without finish) are not available anymore, however the "Light Oak" version is light enough, allowing for additional coatings of your choice.

Got the box? That's great!

If your Gecho board also requires some soldering, please follow this guide first.

Drilling holes for wires

If you find it handier to drill from the battery side, it is a good idea to put some thick cardboard between the lid and rest of the box, to not damage the lid. Or do it other way round, and put a cardboard under the box, to not damage the table.

About Channels, or how Math is not really that hard

What are those "channels" anyway?

It's just a fancy name for program - kind of like washing machine has a program. Gecho has relatively large memory for code - 1MB, of which currrent firmware occupies

Some channels are passive, have no interaction - you can just listen to them. Other react to your input in various forms. Some are for testing and some for settings or programming your own content. The list is long and expanding.

Making of the Synth

I have been fascinated by synthesizers from very early age. My best friend's dad ran a wedding-playing band and he owned Roland JX-3P (just guessing the exact model now, from my memory of silver buttons with red LEDs inside). When he allowed us to touch it after lots of nagging, and we powered it on, my ears immediately noticed it was something out of this world. I was born in Czechoslovakia, a country run by communists, where we spent our days duplicating 10th copy of illegally imported tapes through cheap "International" branded double decks.
