What? Rampart, DIY synth playground kit.

Rampart is designed to allow you to build synths that can be controlled with CV input or produce CV. It has audio/clk input and output, the input being pocket operator compatible. The kit includes a lgt8f328p which has slightly better features than the original Arduino Nano.

Videos of it in action can be seen on the tonetoys site.

By default rampart ships with a bytebeat synth with about 60 formulas. Three categories: rythmical, musical, noisy. But, the all tend to be noisy! The bytebeat synth can, of course, also be modulated by CV input. So, connect a bastl' kastle and have it modulate one of the 3 parameters of the rampart.

Why? Experiment without breadboard.

Don't get me wrong, I use breadboard a lot. But I keep running out of space :) That's why I made Rampart.

I've been making the original variant for years as a means to creating small synths to interact with other small synths like bastl's Kastle. And of course, my own Keep.

All of the Hardware and Software is open source. To build your own you can just use the Fritzing files in the repositories at will :) Or support your dear poetaster :)
