casa.squid.midi — casa.squid/jack 0.2.12

MIDI message parsing and construction logic.

Interpreting and constructing of midi message as byte arrays (signed) or long arrays (unsigned).

(def msg (byte-array 3 [130 64 100])) ;; Middle C on channel 2 with velocity 100

(channel msg)    ;; => 2
(event-type msg) ;; => :note-on
(note msg)       ;; => 64
(velocity msg)   ;; => 100

(event msg) ;; => [2 :note-on 64 100]

aget-byte clj macro

(aget-byte arr idx)

b->l clj

(b->l b)

Signed byte (-127 to 128) to long (0 to 255)

cc-data clj

channel clj

(channel msg)

controller clj

data-full clj

(data-full msg)

Return the data bytes combined into a single integer

Used for pitch-wheel messages.

data1 clj

(data1 msg)

Return the first data byte

Semantics depend on the message type, e.g. note number, controller number, program number

data2 clj

(data2 msg)

Return the second data byte

Semantics depend on the message type, e.g. velocity, pressure

event clj

(event msg)

Convert a message (array) to an event vector.

Given a three element message array, return a four element vector with [channel event-type data-byte-1 data-byte-2]

event-type clj

(event-type msg)

event-types clj

event-val clj

(event-val msg)

event-vals clj

l->b clj

(l->b l)

Long to signed byte

message clj

(message v)

(message channel type & data)

Convert an event vector to a message array

The inverse of event.

note clj

pitchwheel clj

special-types clj

special? clj

(special? msg)

status clj

(status msg)

velocity clj
