Just to further expand on options already mentioned…
Sometimes you’ll find a 16n in a desktop format, with 1/8" MIDI output. $200-$250ish. Check reverb. Here’s one on there now.
Advantages are no need for other hardware, CV+MIDI capability, lots of compatible fader caps to choose from for customizing, and it’s compact. I’m glad such a device exists, as all the Doepfer PocketFaders appear to be hoarded away now
Otherwise, the LaunchControl XL will certainly get it done and maybe it’s nice to also have those pots for FX, and what not, as well.
If you go that route you’ll need a USB MIDI host, unless you want to include a computer in the equation (most people do not).
There’s a gentleman selling some simple, low cost devices that do USB to MIDI conversion (output only) from empty battery pack cases. I have a couple and quite like them. He has one listed on Reverb, and a different one listed on eBay, as well.
I use one of those same USB MIDI host devices with my MIDI Fighter Twister. I used to think I wanted faders too, but with the Twister’s ability to program in specific values when you push an encoder (i.e. push to bring EQ back to center, or push to bring level down to 0), I’ve found that I prefer it over faders. There is a Twister + USB MIDI host discussion here on Elektronauts, if that’s something you wish to discuss.
You’ve got a lot of options, especially when affordable USB MIDI host devices are considered.
