A tremolo works the same way, but then for the volume. You cannot use tremolo on the envelopes, because they are fixed volume. Maybe you can create some effects by switching envelopes, but it is often more versatile to disregard the envelopes and program them yourself using the volume register.A slightly off-topic, but hopefully nonetheless relevant remark for people with an interest in music: actually, a tremolo (Ital.) is a term which in symphonic music is produced by the string section (violins, violas, celli and double basses) by moving the bow very quickly in both directions. Every player (about 60 in a modern orchestra) does this as quickly as he/she can, so that the effect is a very blurry sound.
Tremolo is therefore certainly NOT a variation in volume, but a (mostly long) series of really short tones played directly after each other. However, in popular music, the meaning of the term has been altered by factories producing keyboards and musical software, because a simple variation in volume was easier to implement and it approximated the intended sound more or less.
