Bitwig is the perfect DAW for Scaler as it lets you just slot Scaler directly in front of the VST you want to control on the same track, no messing around with complicated routing / extra tracks etc like in Ableton. Plus on the full version you get a bunch of MIDI note effects that have endless permutations. You can get the 8 Track version free from CM, link is at r/bitwig.
Otherwise if you want a full DAW for cheap / free then I would second Reaper or Cakewalk as many have suggested.
