Minimalist synth and sequencing lib
Contains: - Simple sine, square, saw and noise waveforms. - Hard-edge cut-off filters. - Basic sequencing of a single pattern.
Usage:
```rust extern crate audact;
use audact::system::{ Audact, Wave, ProcessingBuilder }; use audact::notes::stdnotefreq;
fn main() { let mut audact = Audact::new(16, 120, 4f32);
let default_processing = ProcessingBuilder::default().build().unwrap();
audact.channel(std_note_freq(0), Wave::Sine, 1f32, default_processing, vec![0,4,8,12]);
audact.channel(std_note_freq(2), Wave::Square, 1f32, default_processing, vec![2,6,10,14]);
audact.start(1);
} ```
