Dear all, I completed the PHP interface for editing Csound instrument files and updated the documentation accordingly: https://bolprocessor.org/misc/BP3/CheckList.html No emergency to implement the loading of "-cs" files! I will still take time studying more documentation and documenting the Timebase editing. Dealing with Csound instruments forced me to study the old documentation and remember main features : chapter 17 of https://bolprocessor.org/reference-manual-bp2-9-8/ Notably, I understand that "tables" stored in the "-cs" Csound instrument file are not used for creating Csound scores. Their content is ignored by BP and inserted at the top of each score. Therefore they could be kept in memory as a string to be inserted where necessary. I also remembered that BP does nothing with the Csound orchestra file. Its name is saved in the "-cs" Csound instrument file as a reminder that this is the orchestra matching the output. I have a problem here. "-da.tryCsoundObjects" uses "BP2test.orc" provided in the package, whose arguments are used as by default when producing Csound scores in the absence of Csound instruments. However, "-gr.tryCsound" calls "-cs.tryCsound" declaring "tryCsound.orc" as the correct orchestra file. But I haven't found a trace of "tryCsound.orc"… It's an instrument with 13 arguments because many parameters are controlled. It is quite possible that I never designed it, being illiterate in Csound! ;-) I remember checking the proper combination of Csound structures by looking at the result on Csound scores. I've spent several months on these algorithms because of the difficuulty of matching Csound features with BP time model. So, I hope that Csound wizzards will program comprehensive items and instruments up to the stage of sound production… Bernard PS. Rainer, you can post to GIThub the new version of https://bolprocessor.org/misc/BP3/bolprocessor_php.zip with the comment "Editing Csound instruments". Thank you in advance! |
