Welcome to the M-Series family!
You have asked a question that needs a little more info to help. The fixture profiles in MPC are based on a DMX profile of a lighting instrument. So we really need to find out what the LED pars (with no name) profile are. You might have to do some searching around to find this info out. Most likely once we know the name and make, there is either already an MPC profile or a generic that can be used.
A few questions that might help narrow the search. How were you controlling the lights before MPC? Or did you just buy them? If so, from where? Do you have a link to the purchase site that you can share?
A harder way to find out the LED profile is to create a bunch of generic channels / dimmers (say 10) and to go “channel by channel and percent by percent (or value)” writing down how the light responds. Now this can be hard as some lights require multiple channels to have output. (Say intensity on channel 9 and shutter / strobe on channel 10 with RGBW colors on channels 1, 2, 3, and 4. Marcos and effects with speed on channels 5 through 8). You get the idea.
I’d recommend spending some time trying to find out the manufacturer and make before trying to generate a DMX chart from scratch.
Being new to lighting and MPC is great to hear. I wish I had a more definitive answer to your question, but without additional info it’s hard to answer. You might need to purchase a known unit to see how it works and then go back to your LED pars.
Speaking from experience when we first started, our “no name units” have been a bigger headache than they were worth. When we decide to spend a little more for a known name, things got much simpler.
Hope this helps,
