Dear csound-community,
I'm currently making my first steps with csound. I succesfully made my
first very simple trial with additive synthesis. Now I would like to
play with the sound live on a midi Keyboard, but I don't know how to
do it.
 Here is the short csd-file, some comments are in german, for myself
to understand better what's going on.



-+rtaudio=jack -i adc -o dac -+rtmidi=alsa -M hw:1; this option seems
to work, I get no error messages on the linux-shell
;but nothing happens, when I play notes on the midi keyboard

Welcome, Stefan.

Everything looks correct to me, maybe you have several midi input
ports and have selected one where there is no midi coming in? I'm not
sure about the "-M hw:1" part (as I always forget the details of
device selection under Linux, someone else will be able to guide you
there). Just a shot in the dark:
you could try hw:0 instead,
or simply -M0 (without the hw device selection),
or -+rtmidi=portmidi -M0

Do you have a midi monitor application?, as this would help you
determine on which midi port you are receiving data from the keyboard.

best
Oeyvind

Dear Ian,
thanks! It worked.
Next step will be to give each "partials" an individaul envelope.
