How do I create submasters for features built into moving fixtures?

Hey All,

I am new to the moving light world and am trying to teach myself how to successfully busk and have run into a few walls when it comes to programming.  I've been in the incandescent world for over 15 years and I feel like a total idiot to be struggling with some of the more basic functionality of programming when it comes to movers.  

The main issue that I'm trying to solve is figuring out how I can have a submaster that controls built-in functions on fixtures, such as a prism rotator.  I have built a ton of macros for this purpose, and while that is fine in certain scenarios, it would be really awesome to be able to configure a fader that controls the speed of the rotation.  I have recorded a bunch of effect subs that have a master fader, a rate fader, and a size fader, but I'm wondering if there is a way to record a sub that controls the speed of rotation from -110 to +100.  There are other features in the fixtures that I'd love to be able to control the same way, and I'm hoping that cracking the prism rotation will make it possible to do so for other features.  The units I'm working with are the Chauvet Maverick MK II Profiles.  Any and all help is greatly appreciated!!

    This is close, but not exactly what you’re looking for:

    When you record an additive submaster, you’re defining the upper limit of the output when the fader is at full, but the lower limit will always be zero. With Rate and Size on effect subs, you can also define the lower limit, but it must be a positive number. There is no way to have the lower limit be a negative number. This is why putting focus parameters on submasters never really pans out as well as you hope that it will (ha) - those parameters need negative numbers to reach their full range.

    Further, rotation of image parameters like gobos or prisms typically don’t use negative numbers. Rather, they’re a combination of, say, a Gobo Mode parameter and a Gobo Rotate/Index parameter. Gobo Mode is like the transmission in your car when you shift between Drive, Neutral, and Reverse, and and Gobo Rotate/Index is like the gas pedal; Gobo Rotate/Index needs a user-defined positive value, but depending on the Gobo Mode, it will either spin the gobo forwards, backwards, or keep it stationary in a particular orientation.

    If it were me, I’d record a sub with Gobo Rotate/Index at full and then assign the bump buttons to macros that set the Gobo Mode to Rot + and Rot -. If you wanted to smoothly transition from a forward spin to a reverse spin, you wouldn’t be able to move the fader from full, through zero, and into a negative rotation, but you could bring the fader down, click the bump button that changes the Gobo Mode, and then bring it back up to achieve the same effect.

    Thanks Cody!  I appreciate the analogy as it really helped me to understand the order of how its functioning, but I am still running into some issues.  I was able to record the forward rotation at max speed to a sub-master, but when I start to bring the fader down, the rotation doesn't slow down and it stops completely around 56%.  I'm wondering if I need to change the fader from an additive fader to an effect fader?

    Interesting. What color is that parameter when it displays at 56%? Yellow is submaster data, so if it's not yellow, it's coming from somewhere else. Blue, Green, Magenta, and White are various types of cue data, Gray is a home value, and Red is manual data.
