# piper WIP. ``` daw/kick_drum -s kick -m /n/kick daw/ay -s ay -m /n/ay games/orca -u /fd/3 |[3] daw/piper /n/kick /n/ay ``` Instances are created by piper automatically, automatic mixing is enabled by default unless `-m` is passed. Piper accepts simple commands like so: ``` ;00C4d8 ``` `;` is for UDP message, `00` is first instance of the first group (`/n/kick/0`), `C4` is the note, `d` is velocity (`g == 1.0`), `8` is duration (the higher, the less). Duration depends on the current bpm that can be set with a `bpm120` command, for example. Notes can be connected with `:` like so: ``` ;00C4d8:!C2df ``` In this case the second note is for the `B` oscillator of the kick drum, and `!` is a way to "negate" the frequency value, so in fact it's `C2` *negative*. Commands can be separated with `;`. To change the global volume use `vol100` to set it to `1.0`.
