About the Manual This instruction manual covers the operation of the Keystation 49e USB keyboard. Though we do not provide detailed explanation about how to set up your keyboard for use with third party music software, the majority of these software applications will work seamlessly with the Keystation 49e keyboard. Connecting Your Keyboard Before You Connect. . . You can power the keyboard either via USB or an optional external power supply. [. . . ] When used to control these functions, both lights above the buttons will remain on, regardless of the current setting of that function. For example, you may be playing a song with a singer and the singer is having trouble hitting the top notes. In this case, is a good idea to try reducing the pitch by one or two semitones. * This is achieved using a MIDI function called "Transpose. " 7 Transpose works in the same way as Octave Shift above, except the shift is +/- 12. As with Octave Shift, there are two ways of transposing the keyboard. You can use the Octave "+" and "-" buttons, or the black keys F# 3, G# 3 and Bb3. These black keys represent "TRANSPOSE -, " "TRANSPOSE 0" and "TRANSPOSE +, " respectively. To assign the octave "+" and "-" buttons to transpose: Press the Advanced Functions button to get the keyboard into Edit Mode. Press the black key above D1 (named D# 1), representing "DATA = TRANSPOSE. " Edit Mode will finish as soon as D# 1 has been pressed. Press the "+" key and you will hear the pitch of the note you play go up. *A semitone represents the change in pitch from one note to another. So, changing two semi- tones is the same as playing a note two notes higher. Channel MIDI data from the keyboard can be sent on any of 16 MIDI channels. However, certain MIDI devices and MIDI software requires the keyboard to send data on a specified channel. If this is the case, you can change the channel the data is sent using the following method: Press the Advanced Functions button to get the keyboard into Edit Mode. Press one of the 16 channel keys from D1 to E3, whichever one represents the channel you need. For example, if a device specifies that you need to send data on Channel 10, press the Advanced Functions button, and then key F2 to select Channel 10. The Channel can also be assigned to the Octave "+" and "-" buttons. This will increment through the channels. When Channel 16 is reached and "+" is pressed, Channel 1 will be selected. If the Octave "+" and "-" keys are selected to vary the Channel, the lights above the buttons will not change, since it is not possible to have a Channel with a negative value. Pressing both the "+" and "-" buttons together will recall Channel 1. Program Change Program Changes are used to change the instrument or voice you are using. For example, let's change the instrument to a bass sound. To do this we need to send a program change of 32, which will select an acoustic bass sound from the General MIDI Instruments list (see Appendix). [. . . ] Problem 3: When I press a key, there is a delay before I hear any sound. Solution 3: This delay is known as latency. Latency with MIDI signals is due to the softsynth you are using. The softsynth then completes a large number of complex calculations in order to produce the sound you hear­all this takes time. [. . . ]
