A reboot of the original BASSMIDI Driver by Kode54, with more features.

F.A.Q.

Was it really necessary to create a complete separate fork of BASSMIDI Driver?

I feel like it was necessary, yes.

Couldn't you just edit the driver on the existing repository?

True that, I could've just done that. But I honestly didn't want to ruin the original driver.
The driver was born back in 2015, when a friend of mine wanted a version of BASSMIDI Driver with higher polyphony, but then I started working on it more and more, to the point where most of the original source code got replaced by mine.
I really didn't want to ruin kode54's original source code, so I decided to create my own repository. (While still giving credits to kode54, of course.)
Oh, and of course, the driver wouldn't be where it is now, without kode54's help from behind the scenes. He helped me a lot with some issues I was having with some parts of his code. (Which I eventually replaced, but still.)

Do you feel like your driver is complete now?

Tough question... I honestly have no idea. I mean, there's always room for improvement.
But I feel like I have nothing else to add to it at this point, I'm literally out of ideas.
If you're a programmer, and you have some ideas on how to improve or expand the driver's functionalities, please hit me up or send a pull requests with the edits.

Ok ok, enough of your story... What's so special about your driver that makes it different from the others out there?

Good question. The driver has unique features, such as:

  • Automatic rendering recovery. The driver will always try to give you the best audio quality, no matter what MIDI you're trying to play.
  • Spartan user interface, no "fancy graphics" which can distract the user from the original purpose of the driver, and designed for people who aims for features more than for style.
  • The ability to use up to 4 cores/threads, to ensure each function is executed at its best. Each core hosts a vital part of the driver: The first thread hosts the settings loader, the debug info writer etcetera, the second hosts the MIDI event parser, the third hosts the audio render and the fourth hosts the ASIO driver (When using the ASIO angine).
  • Constant updates, to keep the driver fresh and always up-to-date to users requests.

It's meant for professional people who wants a lot of settings to change almost every behaviour of the program.

What do you mean by "for professional use"?

I'll be honest, when I programmed the interface of the driver, I made it to make it familiar for DAW experts or people who know how to use advanced programs.
I've seen newbies getting angry at me after changing one settings, complaining that the driver kept crashing their apps while they were playing MIDIs/working on projects.

If you want something easy to use, I strongly recommend VirtualMIDISynth 2.x by Claudio Nicora.
His driver is definitely more stable than mine, and it's easier to use too. Go check it out.

Can I use your program's source code for my program?

Sure, as long as you follow the LICENSE.

Keppy's Direct MIDI API for developers

You can access the Keppy's Direct MIDI API from here: Keppy's Direct MIDI API Documentation
You can also access the source code for the Windows Multimedia Wrapper here: WinMMWRP on GitHub

Here's a list of applications that currently have native support for the Keppy's Direct MIDI API:

Can you make a WinMM patch for other drivers too?

There's a patch available for VirtualMIDISynth. You can get it here: https://github.com/KeppySoftware/WinMMWRP/releases/tag/4.2A

  • Inno Downloader Plugin
  • Microsoft Windows SDK 10.0.19042

ASIO support details

You can read the lists here: OmniMIDIASIOSupportList folder on GitHub
WARNING: Since I can not test all the ASIO devices available on the market (Mainly because they're not cheap), if you have one, please... Test it with OmniMIDI, then send me an e-mail about it to [email protected].

✔️: Supported
⚠️: Partially supported, or implemented in a different way
❌: Unsupported
* Might require some advanced computer expertise
