Does anyone know if a 2018 Mac Mini i5 and UCX will be able to run pianos like Keyscabe etc. from Logic or other host with maximum 64 buffersize at 44,1 or higher.

I play piano and need low buffersize as a first priority. I already have an UCX and it can run comfortable at 128 buffersize on my older Mac but that´s to high to practices piano.

Will I7 make a difference or do I need a new TB interface ?? I´m a bit clueless of what to buy since I would like to do everything from a future DAW instead of having a Nord etc. on the side for piano stuff....

All the best
