## Example

More information and documentation available at [![GoDoc](https://godoc.org/github.com/mattetti/drumbeat?status.svg)](https://godoc.org/github.com/mattetti/drumbeat).

```go

// define a pattern using text:

patterns := drumbeat.NewFromString(drumbeat.One16, `

	[kick]	{C1}	x.x.......xx...x	x.x.....x......x;

	[snare]	{D1}	....x.......x...	....x.......x...;

	[hihat]	{F#1}	x.x.x.x.x.x.x.x.	x.x.x.x.x.x.x.x.

`)

// convert to MIDI

f, err := os.Create("drumbeat.mid")

if err != nil {

    log.Println("something wrong happened when creating the MIDI file", err)

    os.Exit(1)

}

if err := drumbeat.ToMIDI(f, patterns...); err != nil {

    log.Fatal(err)

}

f.Close()

// generate a PNG visualization

imgf, err := os.Create("drumbeat.png")

if err != nil {

    log.Println("something wrong happened when creating the image file", err)

    os.Exit(1)

}

if err := drumbeat.SaveAsPNG(imgf, patterns); err != nil {

    log.Fatal(err)

}

imgf.Close()

```
