No such luck.
I procured a power supply for my SparkCDM controller and my iPad(Air) declares that it requires too much power, disabling it in the OS, and preventing any app (inc iSpark) from seeing it as connected.
I wouldn't be surprised if it was a parameter that could be set in firmware, but I would be surprised if Arturia released an update for that purpose.
That said, If i come across a neglected SparkLE controller I'm more apt to pick it up.
Keep up the good work Arturia.
cheers.
