When voice was silent, the exponential decays in the filter unit
were causing the high pass component to eventually denormalize,
causing high CPU loads. The solution is the same as in the delay
unit: add and subtract a small number from the value, causing
essentially a flush to zero.

The modulated delay time was converted to int with i32.trunc_f32_u.
This throws runtime error if the modulations caused the delaytime
to become negative, because _u implied that it should be unsigned
integer and negative numbers were out of range. Using
i32.trunc_f32_s fixed this.
Quite often the user wants to experiment what particular unit(s) add
to the sound. This commit adds ability to disable any set of units
temporarily, without actually deleting them. Ctrl-D disables and
re-enables the units. Disabled units are considered non-existent in
the patch.
Closes#116.
The Model was getting unmaintanable mess. This is an attempt to refactor/rewrite the Model so that data of certain type is exposed in standardized way, offering certain standard manipulations for that data type, and on the GUI side, certain standard widgets to tied to that data.
This rewrite closes#72, #106 and #120.
text.Shaper is not thread safe, which caused crash when adding
multiple VSTI plugins to a DAW project. This change fixes that
crash. Further refactorings need to consider where that text.Shaper
should actually reside.
Always appending to the end and consuming from the front cause the
capacity of the slice regularly running out, resulting in new
allocation. With this change, we increment index when consuming
events and append to the end, and when we reset, we move index to 0
and empty slice. This way, we always reuse the allocated memory.
