Hi ! i've been trying to build my first seq patch. I've only been able to write an empty midi file. Why ?
thanks

Probably because you've created a PD patch that writes empty midi files. Share your patch with us and we might be able to tell you how you can make your patch more productive :-)

because you store an empty seq (check properties from seq's popup).
Seq expects a raw midi stream. In particular, it needs a status byte, which is missing in notein's output. A working setup might be midiin -> seq or notein (etc.) -> midiformat -> seq, and seq -> midiout, or seq -> midiparse -> noteout (etc.)
You might wonder, why all this is not documented, but taking a different perspective, cyclone is the best documented part of Pd.
