Ticks make for a nice common way to sync parameters and effects between each other, as well as the current song. For example it is sometimes useful to have delays be in "time" with the song. This means that each trailing repetition of the delay would need to hit exactly on a beat, with the rest of the song. While this would be very difficult to accomplish with units such as "milliseconds", it can be easily accomplished in Buzz by setting the delay unit parameter to ticks and then defining the number of ticks. Remember that each tick is equal to a row, so 4 ticks will delay every 4th row.
