Hi Jesse,
Just wanted to drop my 2 cents in here. I recently replaced an older Echo Audio Layla 3G with the 1824 interface along with replacing a Behringer BCF2000 with a Faderport 8. I have also recently moved from Cakewalk/Sonar to Studio One.
Overall, after the learning curve (which there always is an ongoing one), I am getting used to the combination and finding it to be very comfortable to use and there are a few things that are standout advantages.
Even simple things add to the experience, like:
the ability to mute the output of the monitors from a front panel button or from inside of Studio One mixer view or
the simplicity of using transport buttons on the Faderport that directly map to their software counterparts (and are comfortable soft press lit buttons), or
the handiness of being able to have a locking Shift button on the Faderport hat allows me to start recording a part, then simply hit the Undo button (top right) and having that perform the actions of stopping the playback, undoing the recording, and returning to where I started with the single press or
the ability to record automation across several tracks at the same time while listening and adjusting on the fly with hardware faders that actually feel nice, or
being able to get around the tracks in a number of different ways - by bank, by channel, with the mouse, without the mouse, with buttons flanking the wheel/knob, by using the wheel/knob, etc.
Overall, it's just a great feeling to have so much flexibility to use the system like you want to, but also having everything so custom-made to work directly in Studio One, where other controllers in other DAWs have always felt like everything was a compromise and "close enough" or "I can get used to hitting that unlabeled black button two to the left of the other unlabeled black button" and other variations on that theme...
The 1824 interface sounds good, works as I expect it to, has low enough latency where I'm able to run the whole project without feeling the latency or having my moderately powered PC choke. My last song gave me no issues, no dropouts, and no oddities and was the first full tune I recorded in Studio One, with this interface, and with the Faderport (which you can check out here, though it's about to get a redo on the mix/master due to a few things I don't like:
https://www.blades.technology/music/songs/anythingI got the interface on Musicians Friend on sale, which is now bested by the $100 off I saw on it there last night at $399. I got the Faderport 8 on ebay - new in box, for like $360.
I am super pleased with my home/hobby studio.
Hope you find this post useful.
