I would like to clarify for myself the tempo commands. “BPM ” is an indication of the ideal tempo at the point the command appears in the text score. “BPM @modulate” is an indication of tempo change from the last indicated tempo. So, if I want to indicate a ritard in my piece, what is this the correct way to put it in the score? I have attached a music score with two ritard examples and accompanying asco scores examples.

The command BPM (without the modulate attribute) acts like a reset. It’s thus useful in a musical scenarion where a tempo reset is asked such as after fermatas or ritards depending on context.
The @modulate attribute does a tempo modulation à la Elliot Carter. Here is an example: Imagine an initial tempo of 60 BPM, and a change point of 120 BPM with modulation. This means that it’s the proportion that is important and not the value. If the musician plays at 45 BPM prior to change point, arriving at the pointAntescofo will declare 90 (45*2).
In your score, it looks as if the tempo change on H is more of a reset.
Ofcourse the tempo will affect all ongoing groups, loops and actions in the electronics.
