Fun fact… In general, hardwoods are from trees that drop their leaves annually and reproduce through fruited seeds. Softwoods keep their “leaves” (think needles) year-round and reproduce through exposed seeds. Hardwoods are usually slower-growing and more dense than softwoods, but there are plenty of exceptions.
Basswood is one of those exceptions - a soft hardwood. In hardness/workability, it’s very similar to pine. It tends to have more interesting figure and color than pine, but it’s also a little harder to come by and so more expensive.
If you’re asking in order to get the right settings in Easel, pick either soft maple (as suggested by @MartinW.Mcclary), birch plywood, or MDF. If you’re asking because you’re looking to buy more material, and you’re somewhere in the continental US, get pine.
