Both the audio and midi signals work great and the internal preamp is more than adequate for me.
My software (I have Ableton Live and Cubase) works flawlessly with this and there is very little latency (and I haven't tried tweaking it). No setup, no search for drivers, just instant functionality. As soon as I unpackaged this and plugged it into my laptop, it worked instantly. I only had $50 to spend (I had already spent $30 on an interface that my laptop just would not recognize), and I have had good experiences with the Alesis brand in the past.
The manufacturers simply stopped creating drivers for many devices a few years ago.
Most midi/audio interfaces I found for around what I paid for this ($50), did not work with my Windows 10 laptop. The very bottom LED light illuminates whenever you’re using phantom power. Beneath that is a Midi Out light that illuminates when you’re successfully importing MIDI data from an external controller. Underneath it is a light that illuminates when the USB on your EXPRESS interface is making a good connection with your computer. The highest is a meter that monitors the audio level of your main output. This permits you to blend audio signals from your various inputs with your computer’s audio outputs.Down the middle of the Alesis iO2 interface case are a line of LED lights. At the bottom of the right side of the Alesis interface case, you’ll see the Monitor Mix knob. Another pair of Guitar and Insert jacks are below that input port as well as another Guitar switch and another Gain knob.
The microphone input jack is at the bottom of the left side of the Alesis iO2 USB recording interface along with the microphone’s volume controls.On the right side of these iO2 accessories, you’ll discover another input port for connecting a microphone using an XLR cable. Beneath the Phantom Power port is a switch that allows you to adjust your headphones for stereo or mono. To the left of this switch is the Gain knob that adjusts the volume of the pre-fader and pre-equalizer audio levels. You can use up to 48 volts of power when you run your compressor microphone. The Phantom Power switch facilitates the transmission of DC electrical power, which is necessary in order to run a condenser microphone. When it’s switched to Mic/Line, the channel will accept audio signals from microphones or other line-level equipment. The Mic/Line and Guitar switch accesses a high-impedance output channel for connecting a guitar or bass when it’s switched to Guitar. Next to the line of LED lights that bisects your Alesis device, you’ll see two switches. The Insert port allows you to link your Alesis EXPRESS to a compressor, an equalizer, or some other type of audio signal processor. Just below the mic input is a port for connecting to an instrument or low-line device as well an Insert port. You can connect your microphone to one of these Alesis iO2 USB accessories using any XLR cable. Just beneath the USB port and slightly to the right is a microphone input port.
At the top left of the front of the aluminum case, you’ll find a USB port, which connects to your laptop. Its electronic components are enclosed in a durable aluminum casing.
It’s a portable piece of equipment that you can easily slip into a backpack or a laptop bag. This Cubase software contains an assortment of sophisticated editing, scoring, and mixing tools.The Alesis iO2 USB recording interface measures 5 by 6.2 by 2 inches, and it weighs 12.8 ounces.

The interface provides a compact, two-channel solution that allows you to record up to 24-bit, 48 kHz audio using any software. The Alesis iO2 uses your computer’s own USB port, which eliminates the need for an outside power supply.
It’s compatible with both Mac and PC operating systems. The Alesis iO2 EXPRESS is a capable recording interface for musicians who want the convenience of making music on their computers.
