Waveform Free features an unlimited number of audio and MIDI tracks, all depending on your hardware capabilities of course. So, you can adjust to suit your workflow and the bottom panel changes to display whichever parameters you've selected elsewhere on the screen. In the free music-making app, every section is scalable.
You might not get all the latest features, but you'll receive an update each time the company refreshes its flagship digital audio workstation, which it does almost yearly. The convention seems to be to make the version two iterations before the current one available to download without charge. Waveform Free is the best free music-making software overall, in part because it's an older version of Tracktion's premium DAW.
