The Sample Bank Maker

The whole purpose of AMOS Professional accessories is to make all aspects of computer programming as simple and friendly as possible, while saving the user the time, effort and cost of having to go outside of the system.

A ready-made recording studio is provided for creating your own customised sample banks, and it can be loaded from the "Accessories" disc now:

Load "AMOSPro_Accessories:Sample_Bank_Maker.AMOS"

The Sample Bank Maker screen

A typical working screen is shown below, and all of its features can be easily identified in the short guided tour that follows.

Sample bank Maker Screen

The Current Sample window

The top of the screen is divided into two areas. The left-hand side holds the window which is used to display the current sample being worked on, in the form of a visual "wave pattern". You can load an example and view it in a moment. "Silence" is represented as a straight horizontal line in the middle of this Current Sample Window. The various frequencies that make up the sound of the current sample are displayed as jagged patterns of vertical lines, running left to the right, from the beginning to the end of the sample. As the sample is "played", you can see how the wave pattern corresponds to what is heard. Above the Current Sample Window is a horizontal display panel, which will show the name of the current sample, along with its length, in bytes.

The Sample Bank Window

The upper right-hand section of the screen is where the contents of the sample bank is displayed. Each sample is listed with its own number, name and length in bytes. As you would expect, a vertical slider bar and slider arrows are provided to display any parts of the contents list that are too large to fit into the display. The name of the current sample bank is displayed at the top of this window.

Transfer Buttons

Between the Current Sample Window and the list of samples in the bank are two big buttons, marked with a left-arrow and a right-arrow. These are transfer buttons used to move a sample between the bank (represented by the top right-hand side of the screen) and the working area (represented by the top left-hand side of the screen).

This allows you to pull a sample from the bank, test it or work on it while it is in the Current Sample Window, and then deposit it back at the selected position in the bank. If a copy of a sample that has been worked on is positioned as the last item in the bank, it becomes a new sample to be added at the end of the bank.

The Information Line

A horizontal Information Line runs across the width of the screen, below the Current Sample Window and the Sample Bank display. This reports on the current status of memory, and provides useful messages.

The Control Panel

The lower third of the screen is occupied by all of the control buttons that operate the Sample Bank Maker. Please load some samples now, before they can be demonstrated.

Load Bank
Load bank button the control buttons as usual. Have your "AMOSPro_Examples" disc ready in the drive, and prepare to edit "Mixture.Abk" after pressing the [Load Bank] button. The numbers, names and lengths of all the samples in this bank should now appear in the display window.

Load current sample from bank
Load sample button Now load one of the samples into the Current Sample Window, ready for testing.
For example, select "Bubbler by highlighting its name with a mouse click and pressing the [Left arrow] transfer button. As soon as a current sample has been transferred, all of the other control buttons become active.

Hear a sample
Play sample button If your audio system is ready, [Hear] the current sample now. See how the frequency pattern is shown between the start and end borders of the Current Sample Window. You are now ready to begin editing the sample.

Start and end of sample
Start and end sample button Trigger the small [Start] and [End] arrows to move the settings for the beginning and end of the current sample. As soon as these settings are moved from the left and right boundaries of the window, vertical lines appear to mark the new start and end positions. You can also click directly on the start and end lines in the Current Sample Window, and drag them to change their positions.

Frequency settings
Frequency settings The frequency at which a sample is played is measured in Hertz, and by changing this frequency some wonderful effects can be synthesised.
This panel contains sets of up and down arrow buttons, with Rapid frequency increase button for the rapid raising of the frequency, the Frequency decrease button button for fine-tuning downwards, and so on. Try changing the frequency of the current sample now, by decreasing the Hertz setting. Settings are normally made using the left mouse button, but use of the right mouse button will cause rapid level changes.

Re-name sample
Rename sample button Trigger this button if you want to change the name of the edited sample, before storing it in the bank. Up to eight characters can be typed in after the prompt, and the new name will appear at the top of the screen.

Erase current sample
Erase sample button This button is used to erase the currently edited sample.
It does not effect the original version of this sample stored in the sample bank.

Save current sample
Save sample button When you have finished editing the current sample, you can [Save] everything that is held between the start and end lines in the Current Sample Window as an IFF file on the current disc.
This type of file is commonly used to store data that can be read by different sampler packages and computers. Any changes that have been made to the sample frequency and name will be saved as well as the actual sample data.

Load raw sample
Load raw sample button When a "raw" sample is loaded, its name is computed from the filename, and its frequency is automatically set to 8363 Hertz, which is the Noisetracker default setting. If a sample is held in IFF, its own name and frequency are grabbed automatically.

Return sample to bank
Return sample button If you decide that you want to store any edited changes that have been made to the current sample,
use the large Right Arrow button to deposit the sample back in the sample bank.
The remaining buttons listed below are used to affect the sample bank itself, as opposed to any current sample.

Insert empty sample
Insert sample button This button inserts an "empty" sample at the position which is currently highlighted in the bank. This position can be anywhere you wish. It remains empty, waiting to be filled by an edited copy of the current sample.

Delete a sample
Delete sample button This is a powerful control button, and care should be taken when using it!
The highlighted sample is totally erased from the sample bank, and it can not be recovered.

Clear sample bank
Clear sample button To clear the entire sample bank, use this button.
Again, it must be emphasised that once the samples in the bank have been erased from memory, they cannot be recovered. Always keep back-up copies of your samples on another disc.

Save As
SaveAs button To save the edited sample bank with a new identity onto disc, the [Save As] option should be used.
After a prompt, you can type in the new name for the bank, which will appear above the sample bank window.

Save bank
Save bank button If you do not need to change the name of the bank, simply trigger the [Save Bank] button,
and it will be saved to the current disc.

Quit button To leave the Sample Bank Maker, use the [QUIT] button, which is at the top of the screen, and you will be returned to the familiar AMOS Professional Edit Screen.
