Forum Week 3 - Compossible

This week's forum was wacky. In fact i'm not really sure where to begin. To be honest I'm not quite sure I should say anything at all.

CC Week 3 - OSC Responder

Consider the structure of a MIDI message and build functions that can transmit and receive all note on / off and modulation information between two computers using the OSC protocol. Consider the types of arguments that the function should take to make the function transportable and easily useable on other computers.


// ------------------------------------------------------------------------------------
// RECEIVER SETUP - OSC RESPONDER
// ------------------------------------------------------------------------------------

(
// Open Sound Control Responder
r = OSCresponder(
addr: nil, // nil respond to messages from anywhere
cmdName: "Note Off", // an OSC command (same name as messge sent)
cmdName: "Note On",
cmdName: "Key Pressure",
cmdName: "Control Change",
cmdName: "Program Change",
cmdName: "Channel Pressure",
cmdName: "Pitch Wheel Change",
action: { // action to perform

// Arguments - default
arg time, // OSC time
resp, // responder name
msg, // message
addr // address
;

// Feedback
[time, resp, msg, addr].postln;
}
).add; // add method - adds OSC responder to server
)


// ------------------------------------------------------------------------------------
// SENDER SETUP - OSC SEND USING NETADDR + SENDMSG
// ------------------------------------------------------------------------------------

(
// Setup the Network for the target computer (or the computer that is having data sent to it)
n = NetAddr(
hostname: "129.127.86.100", // IP Address of target computer
port: 57120 // Port Number that SC uses
);
)

(
// Send a message to that computer
n.sendMsg(
"Note Off", // Command Name (Same as OSCResponder Command Name)
"1000nnnn, 0kkkkkkk, 0vvvvvvv" //(kkkkkkk) is the key (note) number //(vvvvvvv) is the velocity
);
// Send a message to that computer
n.sendMsg(
"Note On",
"1001nnnn, 0kkkkkkk, 0vvvvvvv"
);
// Send a message to that computer
n.sendMsg(
"Key Pressure",
"1010nnnn, 0kkkkkkk, 0vvvvvvv" //(vvvvvvv) is the pressure value
);
// Send a message to that computer
n.sendMsg(
"Control Change",
"1011nnnn, 0ccccccc, 0vvvvvvv" // (ccccccc) is the controller number (0-119)
//(vvvvvvv) is the controller value (0-127)
);
// Send a message to that computer
n.sendMsg(
"Program Change",
"1100nnnn, 0ppppppp" // (ppppppp) is the new program number
);
// Send a message to that computer
n.sendMsg(
"Channel Pressure",
"1101nnnn, 0vvvvvvv" //(vvvvvvv) is the pressure value
);
// Send a message to that computer
n.sendMsg(
"Pitch Wheel Change",
"1110nnnn, 01111111, 0mmmmmmm" //(llllll) are the least significant 7 bits //(mmmmmm) are the most significant 7 bits
);
)

AA Week 3 - Drums

Here are 3 recordings done in EMU live space with Dragos Nastasie Vinnie Bhagat and myself. Vinnie Bhagat is playing drums. The sound is natural with no effects, save for a limiter on the master fader to boost volume. The kick was miced with a Beta 52A. Unfortunately there is no hole in the front kick drum skin, so the 52 had to be placed in front. This resulted in a boomy and somewhat undesirable kick sound. The snare's top and bottom were miced with Beta 57A's, which yielded a nice snappy sound with a pleasant ring. We miced the toms with Beta 56's, however the floor tom lacked resonance so we swapped mics with a Beta 56. This was better, though more experimentation with mic placement is needed to achive a superior sound. Overheads were miced with Rode NT5's, which always seem to sound good, although I do believe the one 16" crash we had to use sounds crappy to say the least. A U87 was used for a room mic, which was used subtly. I gained much from this excercise, however I would like to spend more time on a kick drum with a front hole, as well as more attention to mic placement.
