[. . . ] The number just to the right of the comma is an absolute memory address, and the data byte located at that address is displayed at the far right. The CLEAR button will reset the address to the start of the current block. The address is always displayed in decimal and may also be entered numerically by pressing the [#] button. The data will blank out, and you can now use the number pad to enter a different address. Press the [#] button again to return to examining data. DATA DISPLAY F O R M A T The data may be displayed in one of three different formats - absolute value, hexadecimal, or sign & magnitude. To select the display format, press the PARAMETERS button: DISPLAY ABS. Absolute value format (identified by a decimal point after the data) shows the decimal value of the eight bit data in memory. Sign & magnitude format interprets the lower seven bits of data as a decimal number and the eighth bit as a sign (0=positive, 1=negative). Hexadecimal mode (number base 16) is handy for examining MIDI data and is identified by the letter H to the right of the data. Press PARAMETERS again to return to examining memory. MODIFYING MEMORY In the absolute value and sign & magnitude display modes, you may modify the data that is currently displayed by using the number pad and the +/- button to enter a new value directly. Note: The protect status of a block is NOT checked before data is modified with this function. Prommer User's Guide 39 Block Functions Chapter 8 - SOUND MODIFICATIONS The Prommer has several sound modification features which change the data stored in memory. Press the STRETCH button: 2 STRETCH * When you press EXECUTE, this function will stretch the current block to twice its original length. Bytes from the original block are spread out to occupy every other address of the new block and the spaces between are filled with the average value of the data on either side. WARNING: The protect status of the memory following the current block is NOT checked before the stretch function is executed. Press STRETCH again to access the squash function: 2 SQUASH * This function is the opposite of stretch - it will shorten the current block to half it's original length, copying every other byte of the original block to the new block. The new block is located at the same start address as the original block and the leftover part of the original block is not disturbed. When you play back a block that has been stretched, you will hear that the pitch is an octave lower. You should understand that when you squash a block you will lose half of the information contained in the original block, and that stretching it out again will only fill in the gaps with approximated data. Squashing and then stretching a block will act as a sort of low pass filter. Prommer User's Guide 42 Sound Modifications Chapter 9 - MIDI MIDI is a standardized digital communication interface common to many electronic musical instruments. MIDI commands and messages are transmitted serially over a cable between MIDI transmitters and receivers. The commands include such functions as Note-On, Note-Off, Pitch Bend, Program Change, etc. The Prommer is capable of receiving and transmitting several types of MIDI information.
