I record guitar and bass and vox all the time for my Renoise tracks.
I never do it with Renoise. I export the song to wav, and import it into Reaper, and use Reaper to record live audio.
I do whatever number of takes, do some comping, and export what I like to wav. I then import that into Renoise.
The free version is time-limited but fully functional. You can give it whirl to see how well it works.
The discounted price is US $60
The site says this about the discount (which in my experience goes by the honor system):
You may use the discounted license if:
You are an individual, and REAPER is only for your personal use, or
You are an individual or business using REAPER commercially, and yearly gross revenue does not exceed USD $20,000, or
You are an educational or non-profit organization.
It’s great software, especially when you take into account Rewire, ReaRoute, built-in scripting, and an OSC interface (so you can, for example, start/stop recording from your phone).
