Caustic3 is easily overlooked because it started as a mobile beatmaking app. However, it offers a capable all-in-one music production and beatmaking toolkit that you can also use on your laptop. The app includes dozens of instruments and effects powered by a versatile sequencer and a multi-channel mixer. I often use Caustic3 as a beatmaking sketchpad while traveling. Loading the app and sequencing a beat or a bassline takes seconds.
It’s also great for capturing new ideas—the drum sequencers and synths are just a click away, making it perfect for saving new musical ideas for later. Although all free beat-making programs have some limitations, you can still use them as your main digital audio workstation. Once you’re ready to invest in a paid beat-making program, consider purchasing a commercial DAW like FL Studio, Ableton Live, or Logic Pro.
