groundbreaking

My idea becomes a reality with this one small, light device.
I hope there will be more types of electric guitar effect pedals.
The preamp plug-in is very good.

Great little introduction interface

Bought to replace an aging interface and this has done an amazing job. The sound quality of the DACs/ADCs is incredible, the build quality is bar none, the hardware interface is intuitive and well thought out and it's just generally a really neat little package. Looks great on my desk.

I really love the concept of the unison preamps and plugging into a Fender amp feels like nothing I've ever quite experienced when plugging directly into an interface. And that's not to mention the wealth of other preamps at your disposal.

My only disappointment, which is on me, I should have researched more, is that I was immediately surprised by how far one core would go. Especially when using the more CPU intensive plug ins, like that Fender amp, which pushes it almost to capacity and leaves me with few other options in the chain. I mean, I couldn't have afforded the twin anyway, but I would definitely say if you're worried about that kinda thing, to look into what you'll be wanting to use first and their core utilisation.

Otherwise an incredible product, which I'm certain will not be my last.

Good sound, but working bad on my licensed windows

Had some issues on windows, knobs in console isn’t smooth.
No input signal from microphone in obs programm.
And for these money I want plug and go don’t wanna contact support and wait for answers couple days.
Yes sound good and dsp cpu I like it but first of all for work I want stability, so I decided return Apollo after week back to the shop. It’s sad cause I really fall in love with design and sound but I don’t have enough time and nerves for this problem solvings I’m just customer with 500$ And want for them be calm when I’m creating, maybe only my interface was broken

Great little interface

Solid on Win 10 USB. Sounds very good. Console and plugins are a lot of fun to experiment with. Ability to save settings and recall in DAW is awesome! Great interface if you only need up to 2 channels at a time.

RESILIENT BY DESIGN

I've been coveting the UAD platform for a while but couldn't afford to hop in. Thanks to Universal Audio engineering for such a compact 'military grade' device. I can't believe the quality of vocals when tracked using Unison. I used the 1073 and it's mindblowing, I've never experienced such mid-low beauty, what a mellow yet prestine take. Though I mixed using Studio One stock plugins, the difference is amazing! Call me old-fashioned, but next I'm getting the Apollo X4 and the Ultimate 11.

Apollo Solo USB

I have an Apollo Duo for my home studio setup but purchased the Apollo Solo for the purpose of remote recording with a laptop. It's great being able to utilize the unison plugins for this purpose.

Amazing But Needs Windows Performance Improvement

The Apollo Solo USB Heritage Edition I purchased has been the best upgrade to my home studio since I upgraded my mic. This audio interface is hands down amazing, just would be nice too not have any latency issues on windows. The plug-ins that came with it are hands down incredible, they make my old waves versions look like a joke. Overall an amazing product, just slight performance issues on windows.

little..

The reason why I tried to give you 4 stars but took one out is because of compatibility with Windows. I don't know if my computer is a problem, but I think it's not enough to get along with many computers. Please pay attention.
