Apologies in advance, crazy long ramble below:
I had a somewhat similar experience as @circuitghost and @dokev
I purchased it on launch day and messed around with it for a few months, primarily with guitar.
I set up a pedalboard consisting of: Volante, El Capistan, DIG, Polymoon, Echosystem, and Habit. The Habit had far and away the highest quality audio, super HiFi.
I messed around with all of those pedals going into an Aeros Looper and made loop compositions out of them, alternating between one pedal per part (part = 6 tracks), two pedals per part, and three pedals per part. Each track was recorded using only 1 pedal at a time, with no stacked pedals.
I found Stepped Speed, Trimmer, and Filter to be the most useful effects on the Habit, but Stepped Speed can still be pretty finicky to dial in and get useful sounds out of. Trimmer was always easy to dial in and can get you some Drolo Stamme[n]-ish sounds with ease.
I didn’t get along with the Scan knob at all – unless you’re making ambient music in the same key it’ll be hard to get much usefulness out of it unless it’s at it’s lowest possible setting, and even then I would usually just turn it off. Scrubbing/automating the Scan knob didn’t do much for me.
The Spread knob on a very low setting functions as a nice multi-tap delay that isn’t too hard to control and adds a nice second delay. Anything past that didn’t yield useful results for me.
The Size knob is interesting – moving it around doesn’t create artifacts like the Time knob on other delays, but that also makes it much harder to dial in the exact time you want. Tap tempo comes in handy but moving the Size knob even a little after using tap tempo screws it up.
The parts I recorded with the Habit were novel and sounded super high quality, but didn’t really fit into a composition and weren’t really conducive to creating a song ‘world’ on their own. I had a really hard time building interesting parts out of the loops I started with Habit alone, and when I used it to add some flair to parts I made with the other delay pedals, they were fine, but muting them didn’t make me miss them. It felt a little forced.
The pedals I found to be the most fun, creative, useful, intuitive, and quick to create with were the Polymoon, El Capistan, and Volante. The DIG was great too but didn’t take a strong lead on anything. I got some good stuff out of the Echosystem primarily using the more effected modes (ie: Filter, Lo-Fi, Reverse) which added some nice flair that I liked, but it couldn’t really drive a song on its own. I’m sure this is just me – the EchoSystem is nuts and if someone really liked it they could probably recreate every delay sound one could ever want.
Listening back to the 10 or so ‘songs’ I wrote, the Habit parts sound amazing quality-wise, but don’t feel special musically. They’re quirky, weird, and unique but didn’t blow me away. I definitely got an insane amount of wild, high quality sounds out of it, but once they were recorded and I was listening back a week later, it didn’t have much of a feeling to it, it was almost clinical.
On the other hand, the Mood and Blooper (but primarily the Mood) are ALL feeling. Wanna get super specific with what you play into it and how you tweak it? Great, here’s an amazing sound oozing with feeling and emotion. Want to play one note on a $50 Casio keyboard? Fantastic, here’s an amazing sound oozing with feeling and emotion. The Blooper can reach those feelings too but it takes more time and precision.
I chose to sell the Habit because it kept drawing me into playing with it due to visual appeal, sound quality, and curiosity. I was constantly trying to find new ways of working with it, but almost everything I created with it didn’t feel special.
An hour of recording with the Habit might yield a couple sounds I might want to sample and twist around on the Digitakt or Octatrack later. An hour of recording with the Polymoon and I have most of a song composed.
I’m sure people can easily make incredible, special-feeling music with the Habit, but it missed the mark for me. I think that ambient musicians who are less focused on parts and progressions and more focused on subtle movements and variety would get a lot out of it.
Regarding the Microcosm, I had it for a day and just could not get along with it, sold it immediately. I felt like it came with a ghost that just screwed up all of my settings every few seconds. I’m all for ‘playing to the pedal’ but the Microcosm was a little too controlling with too little explanation of what was happening and how to change it.
