add channel option; add figure hide option

 %        The considered bg for this is the  mix of all specified bgs.
 %
 %  This version of simscene allows a lot of options to be controlled, as
 %  optional  'name', value pairs from the 4th argument. Here is a brief 
 %  description of the optional parameters:
-% 
+% save pictures without displaying them
 %  - timeMode: control a time spacing between events. 
 %  		'generate' (default): values must be set for each track using the 
 %                             score control structure
 %  		'abstract': values are computed from an abstract representation of 
 %                   an existing acoustic scene given as parameter

 %
 %  - instanceAudioFile: if timeMode and / or ebrMode are set to 'abstract' 
 %                       or 'replicate', this parameter is the path to the wav 
 %                       file of the reference scene sampled at 44100 Hz.
 %  
-%  - figuresOption: (default 1) save and show pictures (piano roll, time domain stacked visualization, overlaid spectrogram)
+%  - figure: (default 0) save and show pictures (piano roll, time domain stacked visualization, overlaid spectrogram)
 %             0: don't save or display pictures
 %             1: save pictures without displaying them
 %             2: save and display pictures
+%
+%  - channel: (default 0) number of audio channels contained in the file
+%             0: 1 channel (mono)
+%             1: As many channel as sound classes (events+textures)
+%             2: As many channel as sound classes (events+textures). Each
+%                channel is saved in a separated wav file.
 %
 %  - outputFileName: name of generated files with no extension
 %  
 %  - sampleChoice: method for choosing sample to schedule within a track
 %  		'random': unconstrained sampling

 %
 % Uses Mark Paskin's process_options.m from KPMtools
