The TRANSPOSE function allows for a track or part to be transposed by a user specified number of semitones. When TRANSPOSE is held down in part mode, the display reads:
The keypad can be used to enter a two-digit number of semitones to tranpose up from the original pitch (00-99), or the +/- buttons can be used to increment or decrement the amount. Like in ERASE mode, all eight track select LEDs are lit, indicating that the transposition will affect all tracks. If a track select button is pressed, all other track LEDs will turn off, and only the selected track will be lit. Additional tracks can be selected by pressing the select track buttons, which will toggle the LEDs on or off for each track. Pressing the page up or page down button will change the display to:
Now the number entered from the keypad selects the number of semitones to transpose down. For either transpose up or down, pressing the RECORD button executes the transpose command, resulting in the following display:
This display remains until RECORD is released. If a track that is transposed results in an underflow (notes below 0) or an overflow (notes above 127), the track will automatically re-adjust the pitch in octave increments until it is back in legal range.
The TRANSPOSE button does not function while playing a part or song.
The TEMPO button is used to change the tempo of a part or song. The tempo is stored with a song, and not with a part. While in part mode, the tempo remains at its previous setting until changed. While in song mode, the tempo changes to the programmed tempo each time a different song is selected. While in either part or song mode, pressing the tempo button results in the following display:
While holding the TEMPO button, the +/- buttons can be used to select a new tempo, or a tempo can be entered directly with three digits on the keypad. Tempo changes are effective as soon as they are entered, and the RECORD button does not have to be pressed. In part mode, the RECORD button has no function for TEMPO. In song mode (while not playing), pressing RECORD stores the selected tempo into the current song. Otherwise, it is a temporary tempo change that will be forgotten once a different song is selected. If RECORD is pressed, the display changes to:
This remains until the RECORD button is released. In both song and part mode, the tempo can be changed while playing.
The MIDI FILTER button is used to select what type of MIDI information will be recorded by the MMT-8. While holding down the MIDI FILTER button, the page up and page down buttons can be used to scroll through the possible choices, while the +/- buttons can be used to turn each function on or off. The possible displays that can be scrolled through are as follows:
Pressing the + button changes the display to ON, pressing the - button changes the display to OFF. If a function is off, it will not be recorded into the MMT-8, and will not be echoed out the MIDI OUT jack if MIDI ECHO is on. The last page selects which MIDI channel the MMT-8 will record. Normally, it is set to ALL, which means that it will record on all MIDI channels. It can also be set to 1 through 16, which will cause the MMT-8 to ignore all channels but the selected one while recording. Selecting 00 on the keypad will display ALL, and the individual channels can be selected as 01 through 16. The default settings are as shown above, with all functions on except after touch and system exclusive.
