Patch presentation

The patch uses the first  1,2,3,4 outputs and also duplicates them on  to 5,6,7,8 in case you need it.

You should map the 1-2-3-4 outputs as the scheme above describing the loudspeakers around the audience.

The maxmsp patch pre-loads the soundfiles.

when pre-loading is finished, turn dac on with the toggle at the left of the dac~ object.

You can adjust the main level with the fader at the upper right of the patch (default is 0 dB )

You can see the program numbers in the patch  when changing program change with the keyboard (midi channel 1)

Playing a note run a soundfile if one is attached to this note (see score)

You can follow the cues number in the patch display.

The pink bang button is used to stop all the current playing sounds.

The toggle notegates desactivate the note in from keyboard (default on)

The toggle pgmgate desactivates the program change from keyboard (default on)

You can set the audio configuration by double-clicking in the dac~ object.

Top 8 faders give a visual feedback of the current levels of the files played.

To check the midinotes/sounds mapping, have a look in the "p cues" section.

Notes trig cues which combines soundfile, level and enventually pcm pgm change indications.

Cues are triggered by the keyboard with specific notes & pgm change

play_list syntax

"play_list_01" this is the play list where the soundfiles are defined to be played as the following : 

program_change*1000 + midinote , the file name, the level in dB, the output type.

as example the following line "1038 , mes_003.spat 6 4;"

means the file "mes_003.spat" is trigger when we are in program 1 (*1000) and play the D1 (38)  note (1000 + 38 = 1038), then the level is +6dB and the output is 4 i.e. real quadra file

the different types of output  are :

0 off

1 front stereo  (i.e. 1-2)

2 rear stereo (i.e. 3-4)

3 cross stereo  (stereo on 1-2 and 3-4)

4 real quadra (i.e. 1-2-3-4)

- You can test sounds using the graphic keyboard in the "note 2 file" subpatcher, and also change manually the pgm change (1 to 5 are used)
