I do most of my stem separation within SMP.

My test was within SMP testing the two options the new 4-stem-model vs the 6-stem-model both within SMP.

I thought the new 4-stem model should have higher quality without exception so I was a bit surpriced when I found one audio track were the Bass stem was better in the old 6-stem model within SMP.
It is easy to switch between the two models within SMP to check and compare.
My suggestion to drag them over to the DAW was only if one wanted to have all stems for both models side by side for comparisment
