instruments-all-at-same-offset clj

(instruments-all-at-same-offset {:keys [current-instruments instruments]
                                 :as score})

If all of the :current-instruments are at the same absolute offset, returns that offset. Returns nil otherwise.

(Returns 0 if there are no instruments defined yet, e.g. when placing a marker or a global attribute at the beginning of a score.)

Offset clj protocol

absolute-offset clj

(absolute-offset this score)

Returns the offset in ms from the start of the score.

offset+ clj

(offset+ this bump)

Returns a new offset bump ms later.

offset<= clj

(offset<= score & offsets)

Convenience fn for determining if offsets are in order.

offset= clj

(offset= score & offsets)

Convenience fn for comparing absolute/relative offsets.
