68 DSSI only supports state changes when called via UI, no "full state" possible.

69 This also makes it impossibe to use programs and state at the same time with DSSI,

70 because in DPF changing programs can lead to state changes but there is no way to fetch this information on DSSI plugins.

72 To make it simpler to understand, think of DSSI programs and states as UI properties.

73 Because in DPF changing the state happens from UI to DSP side, regular DSSI can be supported.

74 But if we involve programs, they would need to pass through the UI in order to work. Which goes against DPF's design.
