I would like to have an actual tracker VST, but writing one is a pretty big undertaking. Especially if you want decent resampling, a nice way to load samples etc. For me, the main tracker effects I'd use a lot are portamento, offset, vibrato and tremolo, but there are many more.
But eh, it's not something I personally have time to develop, but I would use it if it existed. HT and such a thing could communicate via CCs. I'm sure there'd be ways to make a specialized column that hides these implementational details and have it feel like a normal tracker
Or even make a special version of HT that is meant to integrate with it.
