Why not make a four-measure file and try setting the values to widely different numbers to find out? the message at the top suggests that a setting of 1.00 will change a forte into a fortissimo.
Thank you, that’s a good idea. But I tired it and it’s fine, with seemingly the same settings as my string quartet where the bashing is over the top. I shall investigate further.
I am still curious to know if 1 means take f to ff, then what are the decimal increments along the way? Percentage change? is .5 halfway between f and ff? Sorry to sound dumb!
You’re not dumb at all: those options are not the clearest. 1 = the next dynamic level, so if your note is written as forte, a value of 1 would make that note fortissimo; 0.5 is halfway between the two, and so on.
