Audio architecture
The schematics shown below will help you understand the workflow. The first diagram
demonstrates the Polyend Tracker’s audio signal flow with the list of steps that input sound
goes through in order to be heard through the output (the signal flow is the same for each of
its eight audio voices).
The implemented reverb algorithm code is created by Émilie Gillet of Mutable Instruments
and is used under MIT license.
The second diagram presents each instrument’s amplifying structure.
