locsend :: MultiOut

• opcode : locsend
• syntax :

   a1, a2 locsend
   a1, a2, a3, a4 locsend

• description :

locsend depends upon the existence of a previously defined locsig. The number of output signals must match the number in the previous locsig. The output signals from locsend are derived from the values given for distance and reverb in the locsig and are ready to be sent to local or global reverb units (see example below). The reverb amount and the balance between the 2 or 4 channels are calculated in the same way as described in the Dodge book (an essential text!).

locsig :: (K k0, K k1, K k2) => Arate -> k0 -> k1 -> k2 -> MultiOut

• opcode : locsig
• syntax :

   a1, a2 locsig asig, kdegree, kdistance, kreverbsend
   a1, a2, a3, a4 locsig asig, kdegree, kdistance, kreverbsend

• description :

locsig takes an input signal and distributes it among 2 or 4 channels using values in degrees to calculate the balance between adjacent channels. It also takes arguments for distance (used to attenuate signals that are to sound as if they are some distance further than the loudspeaker itself), and for the amount the signal that will be sent to reverberators. This unit is based upon the example in the Charles Dodge/Thomas Jerse book, Computer Music, page 320.

space :: (K k0, K k1, K k2, K k3) => Arate -> Irate -> k0 -> k1 -> k2 -> k3 -> MultiOut

• opcode : space
• syntax :

   a1, a2, a3, a4 space asig, ifn, ktime, kreverbsend, kx, ky

• description :

space takes an input signal and distributes it among 4 channels using Cartesian xy coordinates to calculate the balance of the outputs. The xy coordinates can be defined in a separate text file and accessed through a Function statement in the score using Gen28, or they can be specified using the optional kx, ky arguments. The advantages to the former are:

• opcode : spsend
• syntax :

   a1, a2, a3, a4 spsend
