 ## Testing

-One can use [ORCΛ](https://git.sr.ht/~ft/orca) coupled with neindaw as

-a live-coding environment under Plan 9, see [piper](https://git.sr.ht/~ft/neindaw/tree/master/piper/README.md).

+`contrib` directory contains a script `o` that provides an easy way to run neindaw with ORCΛ.

-Here a basic example of using neindaw

-manually is shown.

 So far three instruments are available: a simplified kick drum,

 AY-3-8910 and a piano.

+`o` (by umbraticus) will start a nested rio with all neindaw

+instruments, `daw/cfg`, `piper` and `orca` in paused mode.  If you

+have a directory `$home/orca`, it will be the current directory as
