Limaflo MotoMouth Eurorack Module - DIY Build
As the summer is ticks along, we decided to take on a relatively new module. The LimaFlo MotoMouth Formant Filter. MotoMouth was originally a Kickstarter project that was first launched in March of 2017, and thanks to its backers, the MotoMouth was born. Our buddies over at Synthrotek were one of the first to have the DIY kits and you better believe we had to get our hands on this one and line it up for our final July build.
Before we get into the build notes, videos and audio samples, you are probably wondering what in the world that the MotoMouth does. The Motomouth is described as an analogue 3-Band, Sedra + Espinoza Bandpass Filter (DABP) with resonant frequencies that are tuned to the same resonant frequencies that are found in the human mouth and nose cavities.
These frequencies can be varied, independently, to form different ‘mouth shapes’, to emulate vowels such as A, E, I, O and U. In the end, this module can essentially emulate 16 vowels and ‘morph’ or ‘glide’ between each vowel using a single Control Voltage input (1V/Oct), and a Gate to ‘snap’ to each vowel when required.
