The 3-digit LED display shows the status of all your operational settings and separate LEDs light up in response to which pad is being struck, giving you instant visual feedback. The self-recording function records you as you play and retains the recording even after you turn the unit off. Want to expand your sound potential? Use the USB-MIDI output to connect CompactKit7 to your favorite DAW and plug-ins. Sticks are included and so is an AC power supply. But you can take CompactKit 7 with you and play anywhere, by using 6 C batteries (not included).
