Inertia
Sets the 'inertia' of the virtual tape drive, which affects how the tape behaves when the pitch is changed. If the intertia is low, the tape speed will change very quickly. If the inertia is high, the speed will change slowly and their will be an audible period of change.
LFO Speed
Controls the speed of the pitch LFO (in Hz).
LFO Depth
Controls the depth of the pitch LFO.
Mono-ize & Init Pan
These controls let you convert a stereo input signal into a mono one, which is useful when you have the delay taps configured as a ping pong effect. 'Mono-ize' controls the degree to which the signal is converted to mono (from 0.0 meaning no conversion to 1.0 meaning fully mono). 'Init Pan' controls the position in the stereo field of the mono signal.
Dry
Controls the amount of the input signal that is fed directly to the plug-in's output.
Effect
Controls the amount of the effect signal that is output from the plug-in.
Input
Controls the amount of the input signal that is fed into the delay loop.
