MIDI REALTIME CONTROLS

The MIDI realtime controllers may seem confusing at first, but they are really very simple to understand. You probably already know that there are 16 MIDI channels that can be used. Each of the 16 MIDI channels uses basically 3 types of messages; note on/off, program changes, and continuous controller messages. Your MIDI keyboard, in addition to telling Morpheus which note was played, may also send realtime control information, which simply means occurring in real time or live. (You may be using a MIDI device other than a keyboard, but for simplicity's sake we'll presume that you're using a keyboard.) Realtime control sources include such things as pitch wheels or levers, modulation wheels or levers, control pedals, aftertouch, etc. and are used to add more expression or control. Your MIDI keyboard sends out realtime controller information as continuous controllers. There is a set of 32 continuous controllers for each of the 16 MIDI channels. Some of the controllers, such as pitch wheel, volume, and pan have standardized numbers. For example, volume is usually sent on continuous controller #7.

Common realtime controllers such as the pitch wheel, volume, pan and pressure are pre-programmed to their proper destinations. Your keyboard may have other realtime controls such as a control pedal or data slider which can also be programmed to control most of the parameters on Morpheus.

Morpheus is equipped with the sophisticated MidiPatch™ system, which allows you to route any continuous controller to any realtime modulation destination. The MidiPatch system is also very easy to use. First, you must know which controller numbers your keyboard can transmit.

Let's say for example, that you are using a Yamaha DX7 as your master keyboard. The DX has pitch and mod. wheels, a breath controller, a data slider and a foot pedal, all of which transmit their values over MIDI. The standard MIDI controller numbers for the controls are listed below (the pitch wheel has a dedicated controller, PWH).

••• MIDI wind controllers may work better if you assign one of the MIDI A, B, C, D controllers to control volume. This will allow the MIDI volume to be added to the current volume.

The Preset menu contains functions that can be modified by the user and then saved as preset information in one of the user presets. For example, the LFO speed or other parameter can be edited, then the preset can be saved to a user location (0-127, bank 0).

WARNING

Changes made in the Preset menu will be forever lost unless the preset is “saved” using the Save Preset function (page 127) before changing the preset.

To enable the Preset menu

Press the Preset button, lighting the LED. The current screen will be the one most recently selected since powering up the machine. The cursor will appear underneath the first character of the screen heading on line one.

To select a new screen

Press the Home/Enter button or press a cursor button repeatedly until the cursor is underneath the screen title heading. Rotate the data entry control to select another screen.

To modify a parameter

Press the cursor button repeatedly (or hold the right cursor button while turning the data entry control) until the cursor is underneath the parameter value. Rotate the data entry control to change the value.

To compare an edited preset with the original preset

Press the preset button, turning off the LED. The unedited preset is now active. Changing the preset number will erase the edit. To hear the edited preset again, press the Preset button, lighting the LED. The stored version of the preset will be heard whenever you are in the main screen.

To return to the main screen

Press the Preset button, turning off the LED.

••• While the Preset menu is activated, incoming MIDI preset changes are ignored. This is a quick and easy way to temporarily turn MIDI Program Change OFF.

▼ Compare Mode must be turned On in the Master Menu for the Compare feature to work.

••• Entire presets can also be combined to form split or layered keyboards. See the chapter on Hyperpresets in this manual.

• Primary Key Range

Key range sets the keyboard range of the primary instrument. This is useful for creating positional crossfades and keyboard splits between the primary and secondary layers. The key range can be set anywhere from C-2 to G8.

• Transpose

This function allows you to transpose the key of the primary and secondary instruments in semitone intervals by shifting the keyboard position relative to middle C. The transpose range is -36 to +36 semitones.

• Coarse Pitch Tuning

This function allows you to change the tuning of the primary and secondary instruments in semitone intervals. The coarse tuning range is -36 to +36 semitones.

• Fine Pitch Tuning

This function allows you to change the tuning of the primary and secondary instruments in 1/64 semitone intervals (approx. 1.56 cents). The fine tuning range is ± 1 semitone.

• Alternate Volume Envelope On/Off

Each instrument has its own factory preset AHDSR volume envelope which is used if this parameter is set to Off. Turn Alternate Volume Envelope On to use the user-programmable alternate envelope.

••• Use Transpose when you want the instrument's timbre to remain constant.

Use Coarse Tuning when you want to change the timbre of the instrument.

••• Use the Coarse Tuning control to change the tuning of multiple drum instruments.

••• See pages 73-74 for an explanation of the envelope parameters.

••• Shortening the attack and release times of the Alternate Envelope can alleviate channel “ripoff” problems. Morpheus examines the Alternate Envelope to determine if a channel can be reused.

• Primary Alternate Envelope Parameters

This function allows you to adjust the alternate volume envelope parameters for the primary instrument. The parameters are Attack time, Hold time, Decay time, Sustain level, Release time and are adjustable from 00 to 99.

• Secondary Alternate Envelope Parameters

This function allows you to adjust the alternate volume envelope parameters for the secondary instrument. The parameters are Attack time, Hold time, Decay time, Sustain level, Release time and are adjustable from 00 to 99.

• Double + Detune

Double + Detune “thickens” the sound by doubling the sound and then detuning it. The amount is variable over a range of 1 to 15. When Double + Detune is on, a particular instrument will use twice as many channels. If Double + Detune is used for both the primary and secondary instruments, the preset will use four channels per key.
