I had a great time with this carry-on ready setup (here below a quick fragment from one of my first jams, just one pattern to give you an idea).
Needless to say, there’s no shortage of brilliant, compact and affordable tools for on-the-go music producers. Have fun mixing and matching items from boutique and big brands. Experiment with devices that offer an unconventional approach.
Most importantly though, make sure to set some rules. For being creative and productive there’s nothing like a challenge. Constraints can also reboot a project that has gone stale, so why not trying?
At the very least, you’ll strengthen your problem-solving muscle. Try and let us know!
