## There is a large CPU spike when the synth is instantiated while all the delay lines are zeroed out.
|
||
|
|
## Quick changes in roomsize result in zipper noise.
|
||
|
|
## emphasis::Changing the roomsize does not work properly! Still trying to look for the bug... (-josh)::

mono input.

argument:: roomsize

|
in squared meters.
|

|
|
argument:: revtime
|
||
|
|
in seconds.
|
||
|
|
argument:: damping
|
||
|
|
0 to 1, high frequency rolloff, 0 damps the reverb signal completely, 1 not at all.
|
||
|
|
argument:: inputbw
|
||
|
|
0 to 1, same as damping control, but on the input signal.
|
||
|
|
argument:: spread
|
||
|
|
a control on the stereo spread and diffusion of the reverb signal.
|
||
|
|
argument:: drylevel
|
||
|
|
amount of dry signal.
|
||
|
|
argument:: earlyreflevel
|
||
|
|
amount of early reflection level.
|
||
|
|
argument:: taillevel
|
||
|
|
amount of tail level.
|
||
|
|
argument:: maxroomsize
|
||
|
|
to set the size of the delay lines. Defaults to roomsize + 1.
