Congratulations, for now you have found a very creative solution for yourself.
However, I can tell you from my own experience that recording interfaces in the low-priced sector are always only a compromise and never really satisfy.
Even the Focusrite Liquid Saffire 56, which I used before the RME UFX and which already cost around €800, was simply bad compared to the RME interfaces I used so far (UFX, RayDAT, UFX+).
Unstable drivers you couldn't rely on. The encoders only worked on the last 25%, the setting was "micrometer work". The operating software is incomprehensible for me and doesn't offer nearly the possibilities of TotalMix FX.
And especially a well-done, comfortable and logical mixer software like TotalMix FX is so extremely important to "feel comfortable" with a recording interface and to get all the possibilities out of it. After all, you work with it every day.
Many inexpensive recording interfaces don't even offer loopback recording anymore, which is so useful. With Focusrite, the old Firewire interfaces used to be able to do that. This feature was no longer implemented in the later USB interfaces of the Scarlett series.
These are just a few examples to encourage you not to be afraid to spend a few Euro more for it, because it will simply bring you advantages and more fun when recording.
