Got it! Based on what you've told me, it sounds like you might want to consider an interface with a high-quality preamp for recording instruments and synths. Focusrite Scarlett and Audient are both popular options that have good preamps and won't break the bank. If you're interested in Universal Audio, their Apollo Solo might be a good option for you since it has one high-quality preamp, onboard processing, and a relatively affordable price point. Just keep in mind that if you ever need more inputs, you'll have to upgrade to a larger model. Hope that helps!
