Get this error message when trying to write to the device:

"Not enough space to write memory. Please remove some steps."

And that's only writing and assigning scenes to 10 preset buttons... There's still 5 more scenes and buttons to do and assign...

Any suggestions what is causing this, and how can I add the scenes and the remaining 5?

Hi, the RM still has a limited amount of storage available and the size of each scene varies greatly depending on how many steps and how many fixtures in use. when you generate some of the effects, try using the compression slider to save space. 

I have 10 simple ADJ UB 12H bars...  no moving lights or anything fancy.

So I create 1 single scene with a basic square matrix effect...

Uncompressed - 1375 steps

Max compression - 232 steps

The product description clearly states "myDMX-RM allows you to program your light show with myDMX 3.0 software, upload programmed data to myDMX-RM then playback in stand-alone mode without a computer. "

So with full compression and this single basic effect compressed scene I can stll not load this single scene to the RM... it still has not enough space... how limited is this device? and does anyone know what solution ADJ is providing for this?



Are you using over 256 channels of dmx? The RM doesn’t come fully loaded with a full universe. It comes with half a universe. This would also give you the error. 

Thanks for the quick replies...

Though your last comment seems confusing or maybe the way this whole RM is being sold is confusing and illegal... or at least in the EU.

So yea I do use over 256 channels, around 400... which is well within the full universe that I have paid for, and that anyone pays for when purchasing the RM.

Product description of the RM...  "Out of the package, myDMX 3.0 software will run in Express Mode; 512 “Live” DMX channels & 512 “Stand Alone” DMX channels"

So one would assume that when this device is purchased can handle 512 channels of DMX straight away without having to do anything else... it really has to as that what's being sold...

Any tips how I can see if it is limited to 256 channels and where to unblock it?

Ah my apologies, I confused the DMX channels from the Buddy to the RM. your right you should have 512 live and stand alone channels. 
send me your dvc show file and I’ll take a look at it on my RM to see if I can replicate the issue. 
you are using the latest April 2019 release of MyDMX 3.0 right? 


Any update on this? Or has a firmware update been released that fixes this issue?

We're about to have another go at setting this up so would be great to know how to get those shows to work on the RM.



Install the latest 2020 release from the MyDMX 3 product page, and check for a firmware update in Hardware manager and give it a try. 

Hi! Thanks for the reply! Can't seem to find the latest 2020 release  

Went to this link, from there you can see there's only a 2020 release for windows, but not for mac, which is what I am using.
