No. As of version 5.1.3 of Pro Tools and Firmware 1.0 of the Control|24, there is no way to suspend fader movement on the unit.One workaround is to use the Control|24's "Flip Mode" and essentially have the faders show the position of the channel's Plug in parameters on the faders. (refer to page #119 in the Control|24 manual, rev A 01/01))
