Okay for just MIDI/ANALOG synth audio/Decent for vocals/guitar.
This is an average interface, nothing wonderful about it. I use it to send 1/4 out from my synth, I also use the MIDI cables from the synth into the PRO 24, and it works great. The mic pres are just okay. I have owned the scarlett ( way worse preamps/less gain range in this 2 channel range, the more expensive scarletts have better gain range/the claretts too) I have owned the firestudio 8 channel from presonus, I also owned the 16 channe; presonus mixing board/interface. I recently got a ULN-2 Metric halo with jensens/DSP and it destroys the other interfaces/has finally given me the power to have the mixes/amazing control over audio that I have always wanted. The fidelity of the preamps/latency/converters are amazing. Only thing is it has no midi port, so I use the saffire just for that these days. Although many software synths could replace my synth, I love the character of it ( korg radias) If you want a main studio interface and have money, don't mess around with anything under 2 grand. ULN and RME make great stuff. However ULN is best for macs/has the best integrated mixer. The DSP is amazing in the metric halo. I wish I didn't waste my time on the presonus stuff ( both units broke down and had to be fixed within a year or less) Preamp channel on one went out on the mixer within a year or less. The firestudio always clicked popped/had to get repaired) The preamp quality with those cheap interfaces and a decent mic pre ( ISA 2, JOE MEEK) makes it tolerable. But holy crap I dont need any preamps when using my metric halo uln2 and my axe fx 2 xl plus ( i record AES) I wasted about 1500 on the presonus crap. Focusrite is definitely better than presonus crap. But I would go higher end for your main interface if you are like me and just mainly record guitar/vocals/bass/synth. I use superior drummer. I didn't know my mixes and sound could be so great with the ULN 2. If you think you can get good results with the focusrite/presonus/lower end gear good for you, but if you have tone OCD like me and want the best results you need to drop 2 grand or more on your interface. However it will save you money on needing a huge mic preamp. This only applies to people who don't need to record drums. This is basically good for me as a midi interface, but with everything else it is just average. But if you are just getting into the market/dont have money this is a good choice.
