If you play an electronic keyboard, and you prefer to use the audio outputs from your keyboard as the audio source for your JamKazam sessions, then you're in the right place for a little deeper dive into the audio gear you need and how to set it up. There are a couple of different options for how to set up your keyboard for JamKazam, and we'll describe both of these setup options below.
1: Connect Keyboard to Audio Interface
If you're not planning to sing in sessions, then your best option may be to simply connect the audio output ports of your keyboard to the audio input ports on the audio interface for your Windows computer or for your Mac computer using a pair of standard 1/4" audio cables. Below is an image of the two ends of this cable type, just in case you're not sure.
Connect the left audio output port of your keyboard to the left audio input port of your audio interface, and the right audio output port of your keyboard to the right audio input port of your audio interface, as shown in the diagram below. Then plug a pair of headphones into the headphone port on your audio interface. 
In this configuration, you will need to set up and use the built-in microphone on your computer as a chat mic in order to talk with other musicians in your session.
2: Connect Keyboard and Microphone to Audio Interface
If you want to sing in JamKazam sessions in addition to playing your keyboard, or if you want to be able to talk in sessions with other musicians with higher-quality audio than you'll get from the built-in mic on your computer, then you may prefer the setup below.
In this configuration (pictured in the diagram below), you connect either the left or right audio output from your keyboard into a single audio input port on your audio interface. If you set it up this way, the JamKazam application will automatically duplicate the mono audio signal into a stereo signal, so you and others in your session will still hear stereo audio from your keyboard - but this will mean you cannot use pan effects from your keyboard that send different audio through the left and right output ports independently.
If you also want to sing in sessions, you'll want to make sure you have a microphone, a microphone stand, and an XLR cable to connect your microphone to your audio interface (as pictured in the diagram above). If you're not going to sing, you may still want to get this gear, as you'll be doing a lot of talking in sessions, and this gives you high-quality vocal audio, which you'll find you really enjoy. But if you're only going to talk with others in sessions, then you don't have to get this microphone gear, and you can just use the built-in microphone in your Windows or Mac computer to talk in sessions.
Also, if you strongly prefer to pass both the left and right audio output ports from your keyboard into the audio interface, while also using a microphone, then you may consider purchasing an audio interface with 4 input ports rather than 2 input ports. This will cost a little more money, but your audio quality and latency will not be affected by using an interface with a larger number of audio input ports.
For Multi-Instrumentalists
For musicians who play lots of instruments, if you prefer not to have to constantly be plugging and unplugging different instruments and resetting your audio input level as you swap from one instrument to another, we recommend that you read our help article for multi-instrumentalists. This help article provides configuration advice just for you.
