My poor Mixcraft DAW lol

I am using Mixcraft 10 to create a seven-movement piece that is a little over 16 minutes. The damn thing was skipping so much I think I am pushing it to the brim lol. Here are some parts that were running smoothly. It is almost time to use another DAW alongside it that can handle all of this especially when I start putting picture to score. It has about 52 stems so far and I am in the process of replacing MIDI with real instruments. I have the strings done and am now mixing and mastering them. After that I will get brass and woodwinds appointed. Who all plays brass and woodwind instruments? I usually use Fiverr, but I thought I would ask the community first.
