This module expands our line of expressive controls, it follows the heritage of wind/breath controllers with one major difference, the pipe has no air escape creating pressure inside the tube controlled by the user’s mouth. For a seasoned woodwind or brass musicians this working principle may sound unorthodox, however this way pressure can be controlled for longer without the need to breath in or learning circular breathing techniques. It’s relatively easy to control the pressure in your mouth while still breathing through the nose.
The module is provided with a standard melodica pipe which connects to an air filter (providing a receptacle for condensation to form and isolate the sensor) and lastly connects to the module front panel.
The signal captured by the sensor is then sent to two independent sections with exactly the same functions as seen in the signal flow diagram below.
As an example the two sections can be used with different settings to independently control the VCA and VCF of any standard analog voice patch.
PIPE
We’re using a standard Melodica pipe into an air filter that will keep condensation away from the sensor. The air filter is then connected to the front panel sensor input using a silicone tube.
SENSOR CALIBRATION
[RESPONSE] is the main control to calibrate the pressure curve, the knob goes from exponential to logarithmic with linear at 12 o’clock. Exponential will be more reactive to high pressures, logarithmic to lower pressures.
HOLD FUNCTION
This feature allows to hold the current voltage value with the hold is engaged (button led on), the state can be changed either by the push button in a latching manner (push to change state) or via the gate input in a momentary manner (hold on while gate is on)
