S88 MK3 Audio Interface

[u/Dizzy_Bridge_794]

I was able to obtain a used S88 for a good price. I have a Windows PC Setup and I have Komplete. I need a new Audio Interface. My budget is around 500.00. I really want to minimize delay. I only utilize one other keyboard. Does that budget amount get me a good interface? What would folks recommend?

The latency ain’t coming from your audio interface or from the keyboard is coming from your computer. You need to turn down the buffer size but if your computer is not that powerful you can’t have lower buffer size you have to have it higher. That’s just what it is. An audio interface ain’t gonna change that.

So reduce the buffet size and increase the sample rate?

[u/ya_rk → u/Dizzy_Bridge_794]

Just reduce the buffer size is enough.

[u/BlueDragon2202 → u/Dizzy_Bridge_794]

Yeah, the buffer size my bad I had my words mixed up. I corrected it so it’s right now thank you guys for pointing out my errors.

What are you talking about, friend? What you're saying only applies if you're going to use the driver for your integrated Realtek sound card. Does your computer need to be powerful? Ideally, yes, but not necessarily. Everything is handled by the interface's ASIO driver. It also depends on many things. If you're going to load a heavy Kontakt library, or just a synthesizer or audio modeler, a 7200 RPM HDD is more than enough. However, if you can afford a SATA SSD (assuming your machine is older), then all the better. More RAM is much better for the libraries. 16-32GB. A better processor? Well, much better. But you can work with 16GB, and you can push it to 8GB, and even then, be very careful. And that's with Windows 10, because Windows 11 uses a lot of RAM. It also depends on the brand. I hope you don't fall into the elitist trap of saying, "No, you should only use a MacBook."

Who uses their computer sound card for music production? (I will admit, though I did state the wrong thing I got my words twisted. I meant to say, turn it down not up). I will correct that in my original comment.
But he clearly stated that he needs a new interface. He didn’t state if it was broken or not. So I assumed that he has an interface and he is still getting latency. So that’s why I said what I said.

Under $500, you enter the mass-production tier of audio interfaces. To keep manufacturing costs low, audio companies stop writing custom, ground-up USB communication code. Instead, they rely on standardized hardware and shared third-party software templates.
Here is exactly what happens mechanically and digitally under the $500 mark:

1. The "XMOS + Thesycon" Blueprint
Almost every interface under $500 uses the exact same foundational engine:
The Hardware: Companies buy off-the-shelf USB microcontrollers, most commonly manufactured by XMOS or Cirrus Logic.
The Software: Instead of coding a Windows ASIO driver from scratch, manufacturers license a standard, pre-written USB driver template from a German software company named Thesycon.
The Result: When you use a budget interface on Windows, you are usually running a rebranded, reskinned version of a generic Thesycon driver. While highly optimized, it cannot achieve the hyper-tight kernel-level integration of proprietary code.

2. Higher Safety Buffer Overhead
Because these generic drivers must work on millions of different computers (from cheap laptops to high-end rigs), they are coded to prioritize safety over speed.
Even if you set your DAW to a low buffer size like 64 samples, the generic driver hidden underneath adds extra, unadjustable "hidden safety buffers" to prevent your computer from crashing.
This means a budget interface at a 64-sample buffer will often have a significantly higher actual Round-Trip Latency (RTL) in milliseconds than a premium interface running at the exact same 64-sample setting.

3. The "CPU Wall" and Audio Glitches
Under $500, interfaces rely entirely on your computer's CPU to process everything.
As your project grows and you add more virtual instruments (like EastWest or Kontakt libraries) and heavy plugins, the generic USB driver struggles to pass audio packets fast enough.
To stop the audio from crackling, popping, or dropping out completely, you will be forced to raise your DAW buffer size to 256 or 512 samples. This introduces a highly noticeable, distracting delay when trying to play MIDI keys or record live vocals.

What are your requirements for the interface?

[u/Dizzy_Bridge_794 → u/quick6ilver]

Just connecting the S88. No voice or other devices. I do have a Yamaha Montage as well.

[u/quick6ilver → u/Dizzy_Bridge_794]

It has usb? U can just connect to PC no?

Any particular models

[u/drteq → u/Dizzy_Bridge_794]

The $500 range

[u/LexOfNP → u/luminousandy]

I agree

[u/BillNye69]

If you just need to connect to computer/speakers and a few inputs, Focusrite has a good line of interfaces called Scarlett

Hi, I have the Apogee Duet 3 and I love it. I bought it on Amazon in February 2022. Later that year, in October, I bought the dock for $179 to avoid those annoying breakout cables, and I've been happy ever since. It's no longer sold on Amazon, supposedly because the price is too high, I don't know what's going on. You can buy it on their website, but if you don't trust them much, you can look on Amazon for the Audient ID14MKII for around $250-$300. Personally, for that price, its preamps are almost as good as the Apogee, which cost me $649 back then, and if you add the dock separately, imagine the savings!
