Buffers

type buffer

A MIDI buffer.

val data : buffer -> (int * event) list
val create : int -> buffer

Create a MIDI buffer of given length in samples.

val copy : buffer -> buffer

Create a copy of a MIDI buffer.

val blit : buffer -> int -> buffer -> int -> int -> unit
val blit_all : buffer -> buffer -> unit
val merge : buffer -> buffer -> unit

merge b1 b2 merges the buffer b2 into b1.

val add : buffer -> int -> buffer -> int -> int -> unit
val clear_all : buffer -> unit
val insert : buffer -> (int * event) -> unit
