I became aware of Spark a couple of weeks ago. On the one hand, I was irritated that someone else was on the same "voice-controlled guitar playing" thread as me, but then (a) it's validating and (b) they're not really going the same place I am.

Thingamagig understands the underlying composition which means it can automate tones, loopers, lights, cameras, etc. That need was the genesis of this project and that's where its going. Everybody else (including Spark, Fender Play) seems to think the playalong is the end goal, which is why they short circuit the hard work of building the composition library by integrating Spotify or whatever.

Maybe they're right. Maybe I'm right. Maybe we're both right. We'll see, I guess.
