What do you mean, by after starting effects? Where are the FX running from?
The FX Mask attribute, is constructed of 2 sections:
- The top part affects current Fixture Selection
- The bottom part, is the FX Delay mask
Working with FX, you will need to use the Fan <> options. Select, e.g. Fan <> Divide by 2, and click the Wave Per X grouping number again, to 'take selection'
By 'parameter' you mean Base or FX value?
Base values can be applied, using the command '@ [click attribute box], #, Enter (@ Red 55, Enter)
Take a look, at the online manual, which is embedded into the M-Series Support Page
FX attribute values, are set values. Double click an attribute box (e.g. Wave), to get the Direct Access window
