Re: [PD] [PD-announce] hidraw v0.1.0 released.
@Albert thanks for the explanation. You might be interested in looking at the sources of https://deken.puredata.info/results.html?name=hidio the .dek file is just a .zip. It looks that Martin have done all the update to [hid]. I had only checked on Windows and not building myself but the object works and it's supposed to compile on Linux and Mac. -- Mensaje telepatico asistido por maquinas.
