Ukulele Tenor interface apogee

I use MIDI Guitar IOS with a tenor ukulele with apogee interface. What do you think is the best tuning (choice of tunings) knowing that I use the Low GCEA

Hi Dom,
You set string 1 to 4 of the guitar tuning;
G3 C4 E4 A4
string 5 & 6 dont matter


The result is better from the standard tuning by mounting the 4 small strings to GCEA
