    You can check if the On Board Soundcard is good enough.
    Plug in some headphones into the PC and set the OBS as the default playback and record device.

    You will probably need some test software and I suggest the trial of Modartt's Pianoteq. A very low resource program and very simple to setup.

    If that gives you low enough latency you know you need to do other than use HDMI for sound. I still suggest a decent (two mic inputs +MIDI) AI as well.

    Dave.

    Ten or so years ago most were PCI cards (most famously the Sound Blasters which were ***t for you purpose!) Then Firewire external AIs ruled the roost but today USB 2.0 is by far the most common. TB is coming along but is only found in esoteric kit with zillions of channels.

    So, you need a USB interface WITH MIDI ports since the Alesis has a MIDI out and that might give lower latency than its USB connection.

    I have suggested the NI KA6 because I have one and it has the lowest latency I know of for anything close to its price point. To do better I think you would have to look at RME interfaces.

    I asked about your 10/20 because had you been in UK I could have loaned you my KA6 to try.

    Dave.
    Well thank you kindly for that offer. I do wish I was in the UK sometimes. Never been there but I hear good things. Better than the warzone in the Bronx New York that's fer sure. Anyhow, thank you very much for your input and I will consider all of that, especially the interface you suggested. Very much appreciated.

    A sound card really is an audio interface.
    Generally 'sound card' is a term associated with consumer gear or the device built into the computer and generally audio interface means something better, although there are exceptions.

    There are numerous benefits to a standalone external device.
    The mains one are lower noise (power filtering, shielding, balanced IO, and proximity to other noisy gear), and solid drivers from a reputable manufacturer who is concerned with pro-audio performance.
    That's not to say you can't get low latency out a realtek built-in, but drivers from Tascam/Presonus/Motu/RME etc are made with performance and latency in mind.


    All that said, you should be able to work out if you're dealing with an input delay or delay in processing/output.
    In Protools, because that's what I know, there is a meter that indicates midi input.
    If I hit a key and that meter moves late, I know the issue is with the midi input side of things.

    If I hit a key and see immediate midi-input meter movement but the sound is delayed, I know I'm dealing with processing delay or playback latency.

    You shouldn't need fancy gear to play a synth and hear it back in a reasonable time-frame but maybe figuring out which of those two is true will set you on the right path.
    Yes I have talked with other professionals and they also hint that the latency issue might be on the playback side since I am only using a simply controller keyboard via USB to my PC and triggering some VST sounds. Only one VST loaded, and using Reaper, although I have tried Protools, Ableton Live, Cubase, Garage band, bla bla, bla bla. Same result each time. I guess I'll buy an audio interface and try it out. I don't need many inputs because I am not interested in doing audio recording, only triggering sounds in a VST. Purely experimenting with chords in a midi chord package I have to get some ideas where I want my song to go. Thank you ever so kindly for your input and advice. Much appreciated and hello from the Bronx New York to all you cool cats over there in England.

    @ Chili Thank you kindly for your input. I will buy an interface and see what happens. I appreciate all of your replies and I will follow up as to what might have been the issue or if the interface solved the problem. Have a great afternoon folks.

    These fellas are probably all right about the HDMI having some amount of delay, but I like to prove things.
    It'd be worth doing that midi input meter check to be 100% sure.

    Also, if your computer has a regular 3.5mm audio out socket, give that a blast. No reason not to and no reason I can think of that there should be a big delay there.

    If you were recording/streaming etc a dedicated audio interface would be the better quality way to go, for sure.

    Ok thank you kindly for your input and I will try that as well. My sound delay comes after I strike a key. Horrendous 1.5 sec delay. I am only triggering a sound in my VST package and I still get it. I do not want to record audio in at all so I was unsure why people suggested an audio interface but I guess they know what they're talking about because I sure don't, lol. So some thought an audio interface would stop this latency. I am rather unsure which to buy, and also how to connect it to my PC. Thanks again for your valuable input, all of you kind people. Ill keep you updated in case you're interested.

    Yes, your particular situation only really calls for a digital to analogue converter (you still need to hear wtf you are doing? ). Unfortunately there is no such thing well, not in the projjy studio class AFAIK.
    High end makers like Benchmark make one way D to As (and the complimentary A/D) but these are very expensive and contain many functions you do not need.

    But you never know when a pair of inputs can come in handy! Might want to dub some old tapes or vinyl one day?

    Dave.
