Those who only have access to an MSX-MUSIC chip or a Toshiba module with MSX-AUDIO (heath miss an ADPCM sampler) can skip this chapter.

What is a sample?
A sample is a digitized sound, in which case the data of the sample is stored in the computer. The sampler of the MSX-AUDIO always scans for a few thousandths of seconds the external signal (eg the microphone) and converts the incoming value into a number. The time between these scans can vary, this is called the sampling frequency.
[en]5.3=== The Moon Blaster sampler ===
MoonBlaster has the ability to use the sampler of the MSX-AUDIO, and to record, play and edit samples. The sample memory of the MSX-AUDIO is 32 kB and MoonBlaster divides it over 14 samples. These 14 samples together are called a sample kit. In these sample kits you also find the location in the sample memory where a specific sample is located. You can go to the sampler from the music editor by pressing the [F3] key. The following things can be set in the sampler: Adjust sample signal Allows you to set the correct volume of the incoming signal (eg via the microphone). The volume is indicated by a red expanding bar at the bottom of the screen. If you turn up the signal, the bar will continue to expand, if you make the signal softer, the bar will sound less (.
= Start sampling
This is the real sampler, the incoming signal is recorded. A variety of factors can be set for proper sampling. These factors are described below.
Set sample adresses (F4)
This allows you to set the starting address of the 14 samples. This has some advantages: a (sampled) bass drum is not very long, leaving sample memory for a long sample. If you omit a sample (see Section 7), the length of the sample is saved. If you load a sample at a different starting address, then the end address is automatically adjusted. The starting end addresses are stored in the sample kit. The addresses must be entered hexadecimal. This means that the tonal system does not run from 0-9, but from 0-F (after the 9 the A). The lowest possible address is 0000 and the highest possible is 1FFF. Note that leading zeros must also be entered.
Current sumple block
You can use this to select one of the 14 sample blocks. This applies to both sampling and loading and storing samples. There are 14 sample blocks.
Sample frequency
This function sets the frequency of recording the sample. A high frequency means high quality, but short sample, a low frequency means low quality, but long sample. The highest frequency is 16 kHz, the lowest 2 kHz.
Treshold
An incoming signal has a certain volume. With the Treshold ft function you can draw a limit to how loud the signal may be before the sampler is allowed to sample. If this limit is exceeded, the sampler will start working. The border is shown with an arrow, the loudness of the signal is shown with a red bar. This function only works when the Sample Control is set to Automatic (see below).
Sample control
You can set the Sample Control to Automatic or Manual. If the Sample Control is set to Automatic, the incoming sound is only sampled when it is hard enough to exceed the threshold value (see Treshold). However, when Sample Control is set to Manual, it is only sampled if the space bar is pressed again after selecting Start Sampling.
Back to Editor (ESC)
With [ESC] or Back to Editor you leave the sample menu and go to the music edit screen
With [F5] you go to the disc menu. Here you can load and save individual samples or complete sample kits. See chapter 7. For all the above functions money: choose a function with cursors, change a value with the spacebar and then the numeric keys.
