I am using Purr Data Version 2.3.1 (20170828-rev.aaf525e).
I am not able to output any MIDI. I test this with Snoize MIDI Monitor: PD out is available, but nothing is coming through.Like with this simple sound to midi notes patch

sound to midi.pd

@vanakaru The patch works in windows/extended so...... presumably the os midi setup is the problem. Where do you send the midi in Pd midisettings?

Thanks David, I forgot to check the Preferences since I started to use PurrData.
