Pitch by 2HP is an effects module for pitch shifting in the range of +/- 2 octaves. The signal conversion happens in real time and has good audio converters. The W&F (Wow & Flutter) control adds a simulation of vain tape machines to the effect signal, resulting in irregularities in pitch and output speed. A great addition to the main effect. Thanks to the three control voltage inputs, the Pitch, Mix and W&F parameters can be controlled with any modulation source and adapted to the musical process.
