KeyPiano Op
Generates notes based on key presses
Summary (oneliner)
<p>Can be used to generate notes based on keyboard presses together with the <code>KeyLearn</code>-op. For every note the keyboard key can be defined in the corresponding <code>KeyLearn-op</code>, so e.g. you would add a <code>KeyLearn</code>-op, press its <code>learn</code>-button to store e.g. the key code for the key <code>c</code> and then you need to connect its <code>on press</code>-port with the <code>c note on</code>-port of <code>KeyPiano</code>. Please note that key-presses are only detected in the preview window by default (click inside to set the focus).<br>Currently only one key can be played simultaneously.</p> <p>The <code>Note On</code> / <code>Note Off</code> can be connected to a <a href="/op/Ops.Devices.Keyboard.KeyPressLearn">Ops.Devices.Keyboard.KeyPressLearn</a> op.</p>
