; Force feedback registry settings for GUID_Sine.
;
; GUID_Sine is a predefined GUID; applications which want
; to use a sine effect independent of hardware will
; request a GUID_Sine.
;
; The default value is the friendly name for the effect.
;
HKLM,%KEY_OEM%\XYZZY.FFDrv1\OEMForceFeedback\Effects\%GUID_Sine%,,,"%Sine.Desc%"
;
; The Attributes value contains a DIEFFECTATTRIBUTES structure.
;
; The effect ID is the number that is passed by DirectInput to the
; effect driver to identify the effect (thereby saving the effect
; driver the trouble of parsing GUIDs all the time).
;
; Our effect is a periodic effect whose optional envelope
; supports attack and fade.
;
; Our hardware supports changing the following parameters when
; the effect is not playing (static): Duration, gain, trigger button,
; axes, direction, envelope, type-specific parameters. We do not
; support sample period or trigger repeat interval.
;
; Our hardware does not support changing any parameters while an
; effect is playing (dynamic).
;
; Our hardware prefers receiving multiple-axis direction information
; in polar coordinates.
