Currently, the way time argument is interpreted is not consistent across functions that use time as an argument, for example:

time(4) -> 4 measures worth of time
length(4) -> 4 milliseconds

I would suggest to make an integer or fraction represent a multiple/subdivision of a measure and add a time unit specificier if other measures of time are desired, for example:

length(4) -> 4 measures worth of time
length(4ms) -> 4 milliseconds
length(4s) -> 4 seconds

this could be extended to other values, for which there is a default unit, but different units could be specified, for example:

fx(filter low 4) -> filter cutoff at 4 Hz
fx(filter low 4kHz) -> filter cutoff at 4000 Hz or fx(filter low 4k) to save typing
