Ableton Live Lite 10 comes with a lot of products so it’s fairly easy to get a license off of someone. Saves you $100 I think? It gives you 8 audio and 8 midi tracks. Not sure how many you need. I will have one available next week when my mixer gets warranty swapped if you’re interested. You can also ask in the /r/Ableton subreddit if anyone has a key. Usually get a reply fairly quickly.
+1 for Reaper otherwise. I’m new to it but it’s incredibly full-featured if only a little convoluted coming from Ableton
