The Tickle comes in a brushed stainless steel frame with recessed side panels in naturally waxed oak wood. Depending on the firmware mode, the Tickle can either send touch position and vibration data via Class Compliant Audio/MIDI devices or the excitation signal and CV for x, y and gate / envelope. The instrument also features an external input port which lets you override the internal surface sensor and lets you connect future extensions. A limited edition is now available for developers.
