About M-Audio SP-Dual | Electronic Keyboard Pedal With
The SP-Dual pedal from M-Audio performs all the standard sustain, sostenuto, and damping functions that your performance demands. Additionally, they add the versatility of 2 and 3 independent ¼” output cables. This means you can use the SP-Dual with any keyboard that has sustain and/or foot controller ¼” input jacks. The pedal is assignable to keyboard functions such as patch advance, sequencer stop/start and modulation effects-exactly as you require from a momentary foot controller. Frequently Asked Questions Will the SP-Dual or SP-Triple work with my keyboard? The SP-Dual and SP-Triple pedals are built to function with nearly any MIDI keyboard that has multiple pedal inputs. The SP-Dual pedal performs all the standard soft and damping functions while the SP-Triple pedal performs all the standard soft, sostenuto, and damping functions. If you are unsure if you can use two or three pedals, just check the back of your keyboard for available inputs or ask the keyboard manufacturer. The SP-Dual has two and the SP-Triple has three momentary non-latching foot pedals that allow for the ability to be connected and assigned to keyboards that have multiple pedal input connections. MIDI controller pedal inputs can often have the functionality of the port re-assigned. This is dependent upon the controller. In some cases, there are many options to choose from - and those options such as sustain, etc. that can be controlled by a momentary, non-latching foot switch can be assigned. Why would I need two or three foot pedals? Some keyboards have multiple foot pedal inputs. Sustain inputs are fairly common, but some MIDI keyboards will also have an input for expression pedals. An expression pedal input can be used to send additional information to your keyboard or software to modulate a particular effect by using your foot instead of taking your hands off of the keys. The expression pedal can usually be assigned to an effect somewhere in your keyboard or software. In addition to sustain and expression, some keyboards may have particular inputs like "organ swell" that are specific to their model. Usually these are standalone keyboards that emulate organs or pianos and provide the option to add additional sustain pedals to make the experience more realistic. Typically, pianos have several pedals with different functions, sometimes just different versions of sustain pedals, and some keyboard manufacturers may want to emulate this. How can I tell which cable goes to which pedal? The SP-Dual has (2) 1/4" outputs, one for each of its pedals. The left and right connections are labeled on the cable at the point where the connection splits as Land R, respectively. The SP-Triple has (3) 1/4" outputs, one for each of its pedals. The left, right, and center connections are labeled on the cable at the point where the connection splits as L, C, and R, respectively. Are the pedals switchable? The pedals will not have a switch to change polarity and will operate as Normally Open. Sustain pedals act similar to a basic circuit, so saying the sustain pedal is Normally Open is saying that the circuit is open while the pedal is up, i.e. the circuit is disconnected and the flow has been stopped. Whereas, a Normally Closed pedal will close the circuit in it's up position, i.e. the circuit has been connected and electricity can flow openly from one point to the next. This means that connecting a normally open pedal to a keyboard expecting normally closed may result in the keyboard sustaining until the pedal is pressed down. Different manufacturers may program their keyboards to respond one way or the other, while others even design the keyboards to adapt to the preference of the pedal. Just in case, some pedals may come with a switch to change their polarity, but even still there are ways around this without the need for a switch. If you're unsure, you may want to contact your keyboard's manufacturer to see which position they prefer.
