I am an Ableton Live user and I wanted a controller with motorized faders.
Though kind of supported, when all is said and done - it's superficial at best.
My biggest three complains:
1) There is no metering on the channels, rendering the unit almost useless since you can't tell what channel is outputting, but, rather you need to read the ancient, low quality, monochrome LCD display that has terrible view angle to make sure you loose any possible emersion and break your flow.
Technically there is a way to enable metering on these small LCD's but get this - it's different then the Live's. It's some kind of average that looks unnatural and frankly I hate it.
2) It doesn't understand drum racks. I love Live's drum racks and use them all the time. In Live you can expand them and use faders, but Faderport is clueless and you'd need to make a new channel for each element instead.
This means I'm not using the unit at the start of my projects and then I just forget it exists. Really bad, would be a huge improvement.
3) After replacing the unit with something else I thought ok, maybe I can use it for something else, like the inputs on my RME UFX+ or something.
After opening a ticket Presonus has made it clear that it's "only a DAW controller". And not a very good one at that.
Some good sides would be the faders - they are big and feel nice. But it feels as an incomplete solution.
I am sorry to say but I regret buying this unit, at least as an Ableton user. Maybe it's amazing for some other DAW's but I'd advise Ableton users to pass on this.
