Splice Sounds - Create Your Own Shortkeys
Splice Sounds is a simple app for managing your own playlist with shortkey commands. This is done by using the Splice Keypad, which allows you to create your own shortkeys by entering the shortkey into the keyboard. All you have to do is download the Splice Keypad extension from here and you're all set to go.
You can use the Splice Keypad to download, play, delete, stop, or like samples to make your sample selection easier to handle. It documents all shortcuts which are accessible by selecting the extension's menu bar icon. All of this can be done by just using the extension.
