This sketch uses the chanVol command to set a new forced maximum volume for each separate channel. This overrides CXX and volume-col commands throughout and may be buggy (feedback appreciated!). Click/drag across all channels to do a sweeping volume-adjustment, or play with individual channels. Click and drag the progress bar at the bottom to seek through the song. NOTE: the white bars express the current relative volume level, from 0 to 64, according to the commands in the module. It's not supposed to be an FFT spectrum representation! ;)
