As long as it works as well as my MacOS version, I think you’ll like Reaper. I think Audacity uses VST plugins, so anything that Audacity has (compression, EQ, etc) should be immediately available to Reaper along with its own plugins.

Be careful about relying too much on charts… do your best to work on memorizing your music. It’s a skill that comes with practice. Before you open any chart, try playing it without the chart, see how much you remember. The more you do it, the more you will!

If it’s your own music, there’s a chance that you might improve it by misremembering it! You write it down, there’s much less chance of that! 😂🎹🤔😎🤩
