"Don't be scared by the lovely panel graphics, this is actually a really easy to understand module! Basically, stick a trigger signal in the middle and it'll spit out rhythms based on the positions of the knobs - the lower one indicates how many trigger events will happen during each sequence, from none to all, the middle knob sets the sequence length - maximum is 16, so stick it in the middle to get 8 and so on, with the top one offsetting the start point of each sequence. Simple controls that allow you to quickly set up and control complex rhythms - this is a dual module so you get a pair of outputs and they can be controlled individually.

Please be aware that this module needs a 5V power supply in your modular case to work, plugging it in to a standard doepfer case will make bad things happen! Other power systems like that offered by Tiptop have 5V out of the box and it works fine but otherwise you're going to need a 5V adaptor, which is not included in this auction as I used it in a tiptop system. Fair warning!"

Update via translucent_nick in the comments: "the name of this module is a Greek word, and it means "elements" - the correct pronunciation would be 'sti-hi-a'.
excellent module and excellent idea!!!"
