This is a work in progress…
I’ve finally added crescendo and decrescendo ability to my macro preprocessor to Csound. Now, after I’ve generated the wave file, I run it through Csound again to modulate the overall amplitude. I can’t believe I relied on the volume of each note making the increase or decrease in loudness. How cumbersome it was! Every note had to be hand set to the desired volume, and the envelopes changed to implement an increase in sound.
