I'll have a go :) (The LADSPA_IS_* things will need to be added too) /* Hint MOMENTARY indicates that that a control should behave like a momentary switch, such as a reset or sync control. LADSPA_HINT_MOMENTARY may only be used in combination with LADSPA_HINT_TOGGLED. */ #define LADSPA_HINT_MOMENTARY 0x40 /* Hint RANDOMISABLE indicates that it's meaningful to randomise the port if the user hits a button.

Ports can communicate arrays of LADSPA_Data (for audio or continuous control inputs/outputs) or single LADSPA_Data values (for control input/outputs). This information is encapsulated in the LADSPA_PortDescriptor type which is assembled by ORing individual properties together. Note that a port must be an input or an output port but not both and that a port must be one of either control, audio or continuous. */ [...] /* Property LADSPA_PORT_CONTINUOUS_CONTROL indicates that the port is a control port with data supplied at audio rate. */ #define LADSPA_PORT_CONTINUOUS_CONTROL 0x10 - Mike > > - Steve > > > On Wed, 15 Jan 2003 18:13:35 +0000 > > Steve Harris <S.W.Harris@xxxxxxxxxxxxxxx> wrote: > > > > > There have been a few suggestions recently, I'l try to summarise them > > > for comment. > > > > > > MOMENTARY.
