Stitch Synth is a modular, e-textile, analog synthesizer. That's the most concise way to describe exactly what it is, but it's also a bit of a mouthful of jargon. So let's start by breaking down those terms.

## Synthesizer
It's the last word in the sentence, but probably the most important one: 'synthesizer' is what we've come to call a wide range of musical instrument that 'synthesize' or create sound from electronic signals. In contrast to music made using acoustic instruments, or electronic instruments that use recorded samples of other instruments, with synthesizers we create signals that artificially recreate soundwaves.
There are many many types of synthesizer out there. Just look at how many Legowelt has:

Probably the simplest part to understand, 'modular' means that Stitch Synth is made of separate parts, or modules, that connect together. Modular synths have been around since the 1960s, and are still in use today. Classic modular synths use patch cables (the coloured wires in the image below) to connect inputs and outputs of different modules together - personally I'm a big fan of the 'big mess of wires' aesthetic, but it is also pretty complex, and totally bewildering for newcomers to modular synthesis

Stitch Synth is way way simpler - It has 10 modules, and uses metal snaps to connect them (physically and electronically) together.
E-textiles, or electronic textiles, is a sub-field of electronics where circuits are made (partially or entirely) out of textiles. Metallic threads have long been used for decorative purposes in embroidery and dressmaking, but it's only in recent years that these threads, which can be conductive, have begun to be used to make soft circuits.

Four of the modules allow you to play Stitch Synth by touching them. Here's how they work.
