I tried the Sushi-DS on my Samsung Galaxy Tab S2 10" tablet. I'd recommend this as a cheap no-commitment way to try out Light Rider/MyDMX Go.
However...
The Sushi itself is an unreliable POS, and Nicolaudie's passive-aggressive licensing terms are tedious and annoying. (Don't waste your time on their non-Light Rider DMX software - it's poorly-documented barebones shareware.) Once I got Light Rider working, numerous show-stopper issues became immediately apparent:
* The micro-USB input socket on the Sushi is totally unreliable. It glitches if you breathe on it and the Sushi will NOT plug-and-play with Android.
* The Sushi interface draws power from your tablet, and there is no good way to recharge it with the Sushi connected.
* Tethering your tablet to a wired DMX interface is a PITA. Plug in a wireless transmitter and you'll have a clunky dongle hanging off your tablet.
* Light Rider does not automatically detect the Sushi interface after you reboot your tablet. You have to go into the setup and poke it.
* Unlike a MIDI controller, Light Rider must stay actively connected to your lights at all times. When your screen blanks out, your lights do too.
The Sushi was meant for laptops, and since Light Rider only works on tablets, it's an awkward mismatch. I switched to MyDMX GO's wireless interface and it's way more practical and convenient. With MyDMX GO, you get 256 DMX channels and a lifetime license to ADJ's rebranded Light Rider app already activated. There's still one problem though...
When you connect your tablet via wifi to the MyDMX GO interface, you lose all access to the internet. You can't use the ProfileBuilder or download any new fixtures because that requires access to Light Rider's cloud server. There's no ethernet port on the MyDMX GO interface, so you can't plug it into a wifi router and network your tablet to it. In short, the thing is designed to monopolize your tablet rather than integrate with your workflow.
One saving grace: ADJ provides a Light Rider app that runs on an Amazon Fire tablet, which can be had for less than $100. Given its networking restrictions, you might as well dedicate a cheap tablet solely to running MyDMX GO.
