===4.2 Select Waves===
With the first option from the wave menu you can select instruments (waves) with their start volumes for the song. You will see a table with numbers on the left of the screen. These are the numbers that should be typed after the ‘W’ in patterns. This table contains all the waves that will be saved in the song. You can move through this table with the cursor keys.
When you press space now, you will go to the wave list. This list contains all standard instruments MoonBlaster offers. These are the waves as they are stored in the Yamaha ROM. Some of the waves in these list are almost or even completely the same. Often an instrument is used separate and as a part (A or B) of an instrument. These waves are listed more than once to make it easier for the user to use the dual voices. The reason Yamaha did this is obvious: It saves a lot of memory. It would be impossible to put all GM instruments in the 2MB ROM if they did not do this. An other disadvantage is that the tone boundaries can be heard very clearly with some waves.
With [CTRL] + cursor left/right you can move through the wave list. The last columns of the wave list contain the ‘Own Waves’. For more information on own waves, see section Edit Waves. When you have found the desired instrument, press space bar and you will return to the instrument table. With [ESC] you can leave the wave list without selecting an instrument. You can put an instrument on every line in a similar way. These selected instruments can be used for an instrument (wave) change, (see Fout! Verwijzingsbron niet gevonden.) or as start voices. The start volumes of these instrument (displayed behind the instruments in the instrument table) can be modified with [CTRL] + cursor left (decrease volume) and cursor right (increase volume). With [CTRL] + cursors up/down the Level Direct can be switched on or off. This sets the moment where the volume is changed for a wave. When it is switched on, the volume changes immediately, when it is switched off, the volume changes with use of interpolation.
===4.3 Set Start Waves===
This option of the wave menu shows the channels with their instruments. The instruments with the channels are the instruments the song will start with. If for example on channel W 1 and W 2 instrument 1 is selected, and if instrument 1 is a violin with volume 13, the song will play a violin with volume 13 on channel 1 and 2, until this is changed with a V or W event to another volume or wave plus volume.
4.4 Edit Tones
Here you can modify the 64 available tones. Like mentioned earlier, a tone is a sample with some extra information about the effects with this sample. In the left part of the screen are the tones. You can select a tone here with the space bar and cursors. After a selection, the header information can be modified in the right screen.
We tried to bother the user as little as possible with the locations of the samples in the sample RAM. This only happens when you are out of sample memory or there is too much memory fragmentation. The sample addresses that can be set here will not alter the length of the sample in the sample RAM! It will set the part of the sample that is played of course. To shorten the length of a sample a separate sample editor must be used. Maybe we will make one ourselves in the future. Below is a brief explanation of the several possible settings:
Start address: Point within the sample where playing starts. It is not possible to change this.
End address: Point within the sample where playing will continue at the loop address.
Loop address: Point within the sample where playing will loop.
Sample type: Sample type: 8 or 16 bits. You cannot change this. This is set when a sample is loaded.
Freq. table: Frequency table to use when the sample is played. A choice can be made between 22050 Hz, 8363 Hz or 7875 Hz as a base frequency. The frequency will be doubled for every higher octave. The first table is a common one for PC samples, the second is common for Amiga samples and the third is used for most Turbo-R samples.
Attack Rate: Sets the attack speed of the tone. Values 0 - 15
Decay Level: Level where the 1st Decay will change to the 2nd Decay. With decay level 0 only 1st decay will be used. Values 0 - 15.
1st Decay: Speed of the decrease in volume after the attack maximum was reached. Values 0 - 15.
2nd Decay: Speed of the decrease in volume after the Decay Level is reached.
Values 0 -15.
Release Rate: Fading time of a tone. This is the speed the volume decreases after an OFF event. Values 0 - 15.
Vibrato: Sets the vibration of the tone. Values 0 - 7.
LFO speed: Sets the LFO speed. Values 0 - 7. This speed is used for vibrato and AM (Tremolo).
Rate correction: Values 0 - 15. This will set the speed off the attack, decay 1 ,decay 2 and release rate depending on the octave that there played on.
Amplitude modulation(Tremolo): Values 0 -15. Modulates the volume of the sound.
The end and loop address can be changed by 10 with [CTRL]+ cursors op and down. You can set the loop address to the end address and the end address to the start and sample end with the [SELECT] key. The tone name can be changed with the F6 key. Saving a tone on disk is done with F5. After the error message that there is not enough sample RAM left too much memory fragmentation (and on any other moment) F4 can be used. The program will now re-order all samples and place them sequentially in the sample RAM. All small empty memory pieces will be combined to a bigger part of available memory. You can use the DEL key to delete a tone.
