If your using non-DMX effects, and they do not have 0-10v control either, then the only way to control them effectively is via a multi switched controller. This is basically 8 switches on the front, and 2 bulgin or 8 IEC outputs on the back.
These are an easy way of controlling your lighting, But a 10v controller or a DMX switchpack and DMX desk would be a better way. This is because the switched controller has either 2 cables comming out (which is ok) or 8 individual cables to run up to your trussing. Where as the DMX switchpacks, and the 10v systems have mains in and a data lead.
There are various different makes and models, Have a word with Chris, i'm sure he can supply you with a suitable model..
