/*
TODO:
- [ ] Document dependecies
- [ ] Performance improvements:
    - [ ] implement performance monitoring
    - [ ] f32.mul_add() or f32.to_bits() / f32.from_bits()
    - [ ] only calculate connected ports https://docs.rs/jack/0.7.1/jack/struct.Port.html#method.connected_count
    - [ ] Flag volume modulations as dirty
- [x] Support other Buffers than 1024
- [ ]  Features:
    - [ ] Flags to control printing (--quiet etc)
    - [ ] Option to set initial values
    - [ ] Option to limit certain inputs/outputs to certain volumes
    - [ ] Option to ignore certain modulations
    - [ ] GUI/TLI to see matrix and current volumes
    - [ ] OSC: Per Channel Solo/Mute/Invert
    - [ ] OSC: Output Volumes
    - [ ] OSC: Output Levels

A value of 0.0 would be off, a value of 1.0 would result in a unattenuated signal. Values above 1.0 result in amplification.\n\nOSC-Addresses:\n    /ch/<in>/send/<out> <volume>     Set the send volume (in → out)\n\nOptions:\n{options}")
