# 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, but there is no automatic mixer connection yet, so still need to run `mixfs` and do manual `audio/pcmconv -i f32c1r44100` for each `data` entry. 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, `8` is duration. 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 `;`.
