From a recent posting on this forum:
Yes, it will work on
ProTools LE 7.4 Mac.
E-Control is an RTAS
plug-in, so it will work on TDM, LE, and M-Powered ProTools
All ProTools 7.x versions will be supported.
Both PPC and Intel on
OSX 10.3 and higher will be supported.
Nothing planned on Windows at the moment….but who knows what the future will bring.
