Thonk Plinky

Plinky is a powerful 8 voice polyphonic touch synth that specialises in melancholic sounds to lose yourself in. This dream box puts expressive modulation of CS-80 style sounds and lush FX straight into your hands.

Plinky churns out warm-yet-fragile, CS80-meets-the-finest-finnish-melodic-electronica sounds. Every finger press is interpreted by old-school analog capacitive touch plates, polyphonically modulating the digital sound with analog sensitivity. Its lush built in reverb & capable arpeggiator mean you can lose hours to just noodling around – with no other gear than a pair of headphones and a USB power pack. Its intense modulation possibilities (full 90×7 mod matrix with internal accelerometer! 90 sample and holds per voice!) and eurorack connectivity mean it’s as deep as it is fun.
