There is a driver called ASIO4ALL that should work with almost any audio hardware and is good to use in a pinch but if you’re going to use a MIDI keyboard, you really need to get an ASIO capable sound card. It will not be as good as ASIO but it will make the delay shorter. If you don’t have an ASIO capable sound card then adjust the Playback buffering (seconds): on that same dialog to see how low you can get it before the sound breaks up. You will be creating wav, mp3 or midi songs or music loops only. So, if you want to play the sound of third-party software, you need to disable the sound device in ASIO4ALL menu.

Besides an ASIO’s primary function, FL Studio ASIO lets you hear audio from FL Studio and other programs simultaneously. FL Studio’s installation already includes FL Studio ASIO, its own built-in ASIO driver. But in ASIO4ALL you can only play the sound of DAW. Most DAWs need ASIO in reducing latency between the computer server and sound hardware. In this ASIO, you can play the sound of DAW & the sound of third-party software together. It will play any sample file (wav), generator (softsynth, VSTi & DXi) or midi instrument you feed it. The ASIO made by FL Studio is so better than ASIO4ALL. Fully featured multi-track audio and midi sequencer. You may also have to press the Advanced button at the bottom of that dialog and configure the drivers to lower the ASIO buffer latency. FL Studio 20 Bundle Signature All Plugins Bundle (FL &/or ASIO/VST) is the most complete virtual studio currently available. When you first look under Audio device type: (it probably says Microsoft Sound Mapper) see if there is an option that says ASIO in it. Go into Options | Preferences and click on the Audio Device tab. If your audio device came with a driver CD and you did not install it, now would be a good time to do so. If you have a sound card that supports ASIO then you want to use the ASIO drivers for that card. The delay between the time that you strike a note on a MIDI keyboard and the time you hear the sound is referred to as latency. To get the lowest latency you need audio drivers that support ASIO (Audio Streaming Input Output).
