Running Cubasis on an old iPad

Hello, I just registered my UR2MKII interface recently purchased and wanted to run Cubasis LE on my iPad. However, this is an old model (4th generation) in which latest IOS version accepted is v.10.3.3. Is there a way to get Cubasis LE 3 or 2 to run on IOS 10.3.3 or, if really not possible, is there a way to get/download an older version of Cubasis LE from Steinberg that runs fine in this old version of iPad and IOS? Thanks
