The A4 has a bit of an uphill battle before you can artistically merge with it.
But once you’re there, it’s awesome.
The A4 is one of a kind. There’s very little out there that really compares with what the A4 offers. Closest you can find is the Tetra, but all that offers is 4 part multi timbral, and even then the interface is nowhere near as convenient as the A4. All the soundscaping possibilities make it very capable.
It might even offer the most parameters of any Elektron.
Everything about the A4 takes effort to get any sort of worth from it. But you just have to build up those muscles and then it will come more naturally.
Furthermore, the secondhand prices of the A4 mk1 make it hardly advantageous to consider selling. I believe I bought my latest A4 for $530. A steal for what it offers.
Also, sure enough, if you sell it- you’ll probably want another one within 6 months.
Just stick with it. Challenge yourself to make a track just using the A4- and you’ll get along with it better when you reintroduce it with your other gear
