Sometimes the simple things are the most useful. Plankton’s Ninja Stars are a hub for audio and control voltage. Stick something in and it comes out the other ports.
Use it to split up audio from a Eurorack module so you can plug it into all sorts of different processors. Take a CV signal from an LFO and multiply it across lots of other modules. It’s not a new invention but it’s stylishly implemented. I like the central hole that acts as a bit of a cable-tidy.
It accepts mono and stereo TRS signals on 3.5mm connectors. It’s also suitable for headphones. It’s not a mixer although they suggest quite temptingly that weird things may happen if you try to use it as such. It’s tiny, at 38mm across, doesn’t require any power and looks flippin’ awesome.
They are €7.26 per unit, or €18.15 for 3, or €29.04 for a pack of 6.
If you’re not into modular synthesis then this isn’t going to make a whole lot of sense to you, but if you are then check these useful little stars out at Plankton Electronic’s website.
