I've just added experimental support for per voice equalization - sfz opcodes eq1_freq, eq2_freq, eq3_freq, eq1_freqccN, eq2_freqccN, eq3_freqccN, eq1_bw, eq2_bw, eq3_bw, eq1_bwccN, eq2_bwccN, eq3_bwccN, eq1_gain, eq2_gain, eq3_gain, eq1_gainccN, eq2_gainccN, eq3_gainccN.
Note that the current implementation does not provide internal EQ but is looking for specific EQ effects to use - currently it only looks for the triplePara (Triple band parametric with shelves) LADSPA plugin, which is part of the swh-plugins package (http://plugin.org.uk/
). I guess at some later point I'll add a LSCP support for setting the desired EQ plugin to be used for per voice equalization.
Let me know if the current implementation works OK for you.
BTW, Christian was the one who implemented the internal effects in LinuxSampler, I added support for configuring them through Fantasia.
