KeyPiano Op

KeyPiano

Generates notes based on key presses


Can be used to generate notes based on keyboard presses together with the KeyLearn-op. For every note the keyboard key can be defined in the corresponding KeyLearn-op, so e.g. you would add a KeyLearn-op, press its learn-button to store e.g. the key code for the key c and then you need to connect its on press-port with the c note on-port of KeyPiano. Please note that key-presses are only detected in the preview window by default (click inside to set the focus).
Currently only one key can be played simultaneously.

The Note On / Note Off can be connected to a Ops.Devices.Keyboard.KeyPressLearn op.
