David:
Factory algorithm 18 is the only one that employs
the 15-band graphic equalizer. Factory program 232 uses this
algorithm. This algorithm also includes the 5.0 second sampler. If
you want to hear the effect of the 15 band GEQ without all the sampling stuff
going on, just scroll to the parameters for the 5.0 second sampler and switch
the first parameter to "Off".
Hope this helps,
Graham
