You managed to hit one of the two CC numbers that DSSI plugins are not
allowed to use to control parameters. CC 0 and 32 (Bank select MSB and
Bank select LSB) are interpreted by a DSSI host as "change program
bank", and instead of sending the CC events directly to the plugin it
should use select_program() to select a new program bank in the plugin.
If you use any other CC number it should work.
