Muster Ax is an expander module for the Oxidlab Muster modules.
Muster Ax is adding some additional output ports for the Muster A1, Muster A2, and Muster A3 modules.
Depending on the expanded Muster module some of the ports of Muster Ax are outputting a signal. The available ports can be identified based on the green LEDs. If the LED is active a signal is available. On the one hand side, you can access the LFO signals of the Muster modules and on the other hand side, additional pitch signals can be retrieved.
TODO … Since the filter is using internal saturation, the sound is highly dependent on the input voltages. Red LED lights beside the ports indicate any voltage overdrive. If the LED is blinking from time to time, the filter is operating in its sweet spot. If the LED is continuously red, the filter will still work but might result in a harsh sound or unwanted behavior.
