Each kcontrol command includes a line of parameters up to 128 bytes. kcontrol command to set param: cset "name='Waves Set Param' <0x01,0xff,...>" or cset-bin-file "name='Waves Set Param' <path/to/binary/config/file>" alsa-lib v1.0.29 or commit 6ea14c36 and f47480af are required to support the kcontrol commands.
