ADMIN EDIT: The need for this trick was eliminated by the release of London Architect V2 which provides direct limiting of range on a gain object.
Range Limiting Gain Controls
Many times you do not want to give the end user a gain control that has its full range as this could allow the user to damage the system or create a non functioning state. If this gain control is attached to a control port or on a BLU-10 remote, this can be accomplished through a work around. This example will look at a single channel of audio but the theory can be expanded to N-gain objects as well.
We will use a 2x1 mixer instead of a singl gain processing object. Wire your signal to both inputs of the mixer.
Open the default control panel. Unmute all the channels. The output master becomes the control to set the maximum level or upper range limit of this gain circuit. We will use input channel 1 gain control as the control that will be tied to the control port or added to the BLU-10. This control has a full range of +10db to – 100db. To set the maximum range for this control, set channel 1 gain to its maximum (+10db). Now adjust the output master gain control to achieve the desired maximum output level. Now set input channel 1 gain control to it minimum (-100db). Now adjust input channel 2 gain control to achieve the desired minimum level of this gain circuit. The user can change the control over its full range of motion but we are limiting the overall gain of that range.
