Live Audio Input Setup

You will need to setup your soundcard properties correctly before Rapid Evolution will detect keys from the live input. Please note that the steps below may differ to what you see depending on your soundcard.

You can access the recording settings from the Volume Control which is often accessible from the taskbar. If not, you can access it via Control Panel→Sound and Audio Device Properties→Volume→Advanced:

When you get to your Volume Control, then go to Options→Properties:

Change the “Adjust volume for” setting to “Recording”, then click OK:

You should finally see your Recording Control, with the ability to select different inputs. The input options will vary depending on your soundcard:

The input that you select here will be the one Rapid Evolution picks up on when detecting from live audio input. If you are getting your input from an external source then you should select the appropriate input rather than 'What You Hear'. Doing this will prevent the notes played on the MIDI keyboard from influencing the detected key. Also, uncheck everything that isn't used, even if nothing is connected to that input, as this will reduce the amount of noise and improve audio quality.

The input settings are controlled in the Sound section:

This section needs to be expanded. If you're a Mac user and have done this, please contribute

After you have configured your recording input settings in the operating system, it is good practice to test and make sure the key detector is getting the right signal. If your recording input is set such that it grabs the audio you hear, you can test by enabling the key detector and then playing and holding a note or chord using the MIDI keyboard. The key detector should reflect whatever notes you have played. When the recording input is set incorrectly then Rapid Evolution will tend to display the same key regardless of the audio input.
