Completely Useless
This app will not run properly on my mac book pro regardless of what settings are used for buffer etc. Playing one single chord on a piano sound with no plugins or effects peaks the CPU out to 500% (no really sure how that is possible) and the sound is full of glitches. This same computer is used for film scoring and runs Nuendo, all east/west sample libraries and BFD2 flawlessly. I have since installed the full version of Ableton Live which runs perfectly and uses approximately 5-10% of my CPU power when running many instruments and plugins concurrently. Long story short, you get what you pay for.
