Hi devs, I would like csound6~ for Max to receive t score events, but I see that in the API manual: " 'type' is the score event type ('a', 'i', 'q', 'f', or 'e')". 

Questions: 

- why is the t event not supported? (curious)

- is the only way to do this through the csoundInputMessage call or is there some other way of setting the tempo?

thanks

because it's a score preprocessor event that is done before Csound starts running. Tempo is an interpretation of score p2 and p3 and not

something that the engine does.

Further to this, I am getting an error when I try to send "t 0 120"  to csound through csoundInputMessage, even though this is a valid score line. I get:

unknown opcode

illegal RT scoreline:

t 0 60

Any suggestions most welcome!

I don't think the Csound language (i.e. the "orchestra") has the concept of tempo. That is something that exists in the numeric score (by the way of its preprocessor) and gets interpreted there. It's a controller-specific thing. You would need to use Cscore (etc) to do any extra preprocessing, but that has nothing to do with the Csound language or engine per se.

Once Csound is running any score events sent to it are taken as realtime events. The csoundReadScore() function can do a certain amount of

preprocessing and send in the corresponding score events (to be taken as realtime events), but off the top of my head I am not sure tempo or

sections are available.

oh interesting. So is there no way to change csound's tempo from the API as it plays? Or do people just translate everything into seconds from the host?

thanks for the explanation Victor.
