I just got a 25 key Novation Launchkey and I actually really like it. I think your your purposes you’d obviously get the larger versions that come with faders as well.
The keys feel good and what you’d expect for synth action. Velocity seems pretty responsive, but no aftertouch. Solid pitch and mod wheels.
The pads feel ok, similar to the RYTM but softer and more responsive. They also have aftertouch. You can also easily change the midi channel of the keys or pads, switch from a couple of different presets for the pads (chord mode, drum mode, midi CC mode) or get very specific and make your own setups where each pad can be configured with its own midi action and midi channel individually.
I also like that outside of the really advanced custom setuos, you can switch and control almost everything else from the front panel, no software needed, so with that and Midi out, it should last s long time even if the software doesn’t my get supported.
I’ve connected this directly to my Iridium’s control in and it was a lot of fun.
My only gripe is that the aftertouch and velocity on the pads can be a little finicky, but they’re adjustable so I probably need to change some settings to fix that.
