Don't use a matchbook, your elbow, a spare toe, or masking tape. Use the Key Dog to hold down a key on any synth, organ or EP. The Key Dog obediently sits on a key and holds it down for as long as you want. And like a real dog it's color-blind: it handles black and white keys with equal ease.
The Key Dog is a laser-cut steel weight that strikes a balance between maximum weight and minimum size. It fits great on any keyboard with regular-sized keys and is easy to place and remove. It works on some small keyboards such as the Roland Aira System-1. It will work on some minikey controllers, but you'll have to be more attentive when you place it onto a key. A groove along the upper edge provides excellent grip for your fingertips. Rubber on the bottom keeps it from slipping out of place.
You might think that a sustain pedal does the same job as a Key Dog. In some situations this is true. But in fast-paced performances you might need to instantly turn a synth sound into a drone without having your body locked in place to hold down a sustain pedal. Another benefit comes about during improvisation: the Key Dog provides a visual indicator of the note that's being sustained. If you're feeling fancy (like me) you can use 2 or 3 Key Dogs to hold down chords.
