===3.3.2 Special options===
The special functions effect the tone in the desired way. With a number you have to enter several digits. Enter [RETURN] to end the input if you want to enter fewer digits than the maximum length.
�Detune
The detune is an option that slightly increases or decreases the tone height of a channel (maximum of 3 frequency steps above or below normal). This can be used to give the song a ‘full’ effect. The detune is entered with the [T], followed by a [+] or [-] and a number between 0 and 3. In the pattern the detune command is displayed by the T, for example ‘T+1’. The detune option in MoonBlaster always calculates from zero, so a detune is not added by the last detune (T+1, followed by T+3 will not be T+4). The detune will note take effect until a new note is played. The start detune settings are done with [F10].
Pitch bend
A pitch bend event bends a tone frequency smoothly up (+) or down (-). This is entered with [P] and a [+] or [-]. Next, you type a number between 0 and 9. This is the speed of the pitch bend, 1 is slow, 9 is fastest. Speed 0 will halt the pitch bend. Pitch bending also stops with a new note, OFF, or modulation event. A pitch bend is displayed with a P, for example ‘P+3’. The overall speed of the pitch bend is also affected by the base frequency. (see chapter)
Modulation
Modulation is entered with the [M] key followed by a 1, 2 or 3. Modulation modulates the frequency of a tone. This will stop with a new note, OFF or pitch bend event. Modulation is displayed with the M, for example ‘M 1’. The modulation wave to use is selected with the number after the M. These modulation waves can be edited with [CTRL] + [Y]. A menu appears where you can alter the current values with [CTRL] + cursors left/right. It is possible to make your own pitch bend here when you do not ‘modulate’ up and down, but only one way. It is highly recommended to use the hardware vibrato instead of the modulation (it is the same). The hardware vibrato is not affected by the base frequency and uses no processor time at all (only to start it that is).
Linking
The linking option plays a new note without triggering it. A smooth change is made from the last note to a new note. A link is entered with the [L] key. Next, you type a offset to which note the link should be done, this is from -9 to +9. This is entered with the [+] or [-] and the numeric keys. The offset is added to the current note and is given in half tones (this equals the difference in tone height on two keys from a piano, the black keys must also be counted). Examples:
�From:To:Link command:
C 5 C#5 L+1
E 3 D 3 L�2
A#6 F 7 L+7
After a link a new link can be entered, this will be added to the last link.
Volume change
The volume of every channel can be set with the [V]. After pressing the [V] you can enter a value from 0 (weak) till 31 (loud). In the pattern a volume change is displayed with a V, for example ‘V30’.
Waves
A maximum of 48 different waves can be selected with a start volume. These instruments are used to change the current instrument during the song. This is done with the [W] key. Next, you enter a value between 1 and 48. The values after the W correspond with the values in the list of selected waves. See chapter 5 for more information on Waves. In the pattern a wave change is displayed with a W, for example ‘W 7’. Notice that with the instrument, the volume changes too!
Stereo settings
After the S option, entered with the [S] key, a value from -7 to + 7 can be entered. -7 plays the channel completely left, +7 plays completely on the right. An in between value sounds better of course. Also selectable with [F-8].
LFO Settings
The LFO settings can be used entering the [X] key and a value from 1 to 9. With this option you can alter the LFO speed, Vibrato dept and Tremolo dept of a wave currently playing on a channel. It works in the same way when if you were using a the modulation. The values of these LFO settings can be set as you like by using the LFO editor (CTRL-V).
Reverb on
The opl4 has a build in pseudo Reverb and this can be triggered by entering the [R] key. The ‘Reverb’ will start after an OFF command.
Reverb off
The pseudo Reverb can be set off by entering the [Q] key.
LFO
The LFO from any wave can be stopped with the LFO command and started again by using it again. You enter this by pressing the [Y] key.
