Hi,

If there is something you cannot do with csound, do it in python!

Would

and

help you?

greetings,

Hi list

I'm trying to do some fairly easy (I think) printing to file, but for some reason I can't figure out how to do it. Here's what I'm trying to accomplish: I want an instrument to write a custom string to a text file once for every invocation. I would like the file to stay open through the course of the performance so that the instrument appends to the text file instead of reopening and overwriting it on every new invocation. Is that possible? fprints doesn't seem to do the job.

Thanks,

Alex

hi alex -

of course this is possible. one solution:



instr Print
kPrint metro 1
kCycle init 1
if kPrint == 1 then
fprintks "write_out.txt", "kCycle = %d\n", kCycle
kCycle = kCycle + 1
endif
endin


i "Print" 0 10



if you need to write at init-time instead of during the performance, you 
can have a look in the csoundqt example "ImitativeAdditive" (Examples > 
Synths).
