Grab an Arturia SparkLE.
It runs on modest resources, and it’s cheap. You can use that hybrid drum machine to dip your feet in and see how you like it. Plus you can use it without looking at the computer screen too much.
The Rytm is great but the SparkLE is so cheap it’s almost silly NOT to have one, and just tons of fun to play. Plus it’s a heck of a lot easier to get your head around than the Rytm.
