OSC.jl provides an implementation of the OSC binary format commonly used in networked control of musical applications. The code is based on a relatively straightforward translation of librtosc(https://github.com/fundamental/rtosc)
i = Int32( 42 ); #integer
f = Float32( 0.25; ); #float
s = "string" #string
b = s; #blob
h = Int64( -125; ); #long integer
t = UInt64( 22412; ); #timetag
d = Float64( 0.125; ); #double
S = "Symbol" #symbol
c = Char( 'J' ); #character
r = Int32( 0x12345678 ); #RGBA
m = Array{UInt8,1}( [0x12,0x23, #midi
0x34,0x45]);
#true
#false
#nil
#inf
msg = OscMsg("/dest", "[ifsbhtdScrmTFNI]", i,f,s,b,h,t,d,S,c,r,m);
show(msg)This produces:
OSC Message to /dest
Arguments:
# 1 i:Int32 - 42
# 2 f:Float32 - 0.25
# 3 s:String - string
# 4 b:Blob - Uint8[115 116 114 105 110 103]
# 5 h:Int32 - -125
# 6 t:Uint64 - 22412
# 7 d:Float64 - 0.125
# 8 S:Symbol - Symbol
# 9 c:Char - J
#10 r:RBG - 305419896
#11 m:Midi - Uint8[18 35 52 69]
#12 T: - true
#13 F: - false
#14 N:Nothing - nothing
#15 I:Inf - nothing
Accessing the fields is done via the [] operator.
Most of the usage is going to involve sending the OSC messages over UDP to another program. To do this, first start two julia instances. In the first one run
using Sockets
using OpenSoundControl
sock2 = UDPSocket()
bind(sock2, ip"127.0.0.1", 7777)
msg2 = OscMsg(recv(sock2))
show(msg2)The first instance will now wait for the second to send an OSC message. To send the an OSC message, in the second window type.
using Sockets
using OpenSoundControl
sock1 = UDPSocket()
msg1 = OpenSoundControl.message("/hello world", "sSif", "strings", "symbols", Int32(234), Float32(2.3))
send(sock1, ip"127.0.0.1", 7777, msg1.data)- Port bundle message support from librtosc
