akjmicro / microcsound Goto Github PK

I have installed microcsound via pip on Debian 12 (in a virtual environment), with csound 6.18 and python 3.11 installed via apt. When trying the example from the repository, i.e. microcsound -v ciconia.mc, I get the following result:

orchname:  microcsound_basic.orc
--Csound version 6.18 (double samples) 2022-11-24

sr = 44100.0, kr = 44100.000, ksmps = 1
0dBFS level = 1.0, A4 tuning = 440.0
audio buffered in 256 sample-frame blocks
writing 1024-byte blks of shorts to ciconia.wav (WAV)
SECTION 1:

csound command: Segmentation fault
   end of score.		   overall amps:  0.00000  0.00000
	   overall samples out of range:        0        0
0 errors in performance
512 1024 sample blks of shorts written to ciconia.wav (WAV)

The same issue occurs if I first run microcsound -s ciconia.mc > ciconia.sco and then manually run csound microcsound_basic.orc ciconia.sco.

(Unfortunately, I also have not been able to run the other, much smaller examples from the documentation: They do not lead to segfaults, but apparently use an orchestra file different from microcsound_basic.orc from the repo, as the number of p-fields do not match. The result is a longer WAV file, consisting of silence.)
