Alesis DATADISK Direct MIDI to Disk/Universal Data Storage USERS MANUAL[...]

INTRODUCTION Alesis DATADISK Direct MIDI to Disk /Universal Data Storage INTRODUCTION The DATADISK is a real-time MIDI data storage and retrieval unit capable of storing 800K bytes of data onto a 3 1/2" floppy diskette. Unlike similar units which store data to a large RAM (Random Ac- cess Memory) buffer before processing, data in DATADISK is s[...]

INTRODUCTION 3 HOW TO USE THIS MANUAL Since a musician's time is better spent making music than read ing manuals, we've tried to make this manual not only easy to use, but also fast and easy to find things when you need to. Therefore, the manual is broken down to 6 major sections, of which Section 5 will be probably be referred to the mos[...]

SECTION 1 SECTION 1 DATADISK QUICK START TO FORMAT A DISK DATADISK will use any standard 3 1/2" double sided, double den sity floppy diskette, but first the disk must be customized for use in DATADISK . This is called "Formatting". 1) Insert Disk 2) Press the FORMAT button. The display will read: "FORMAT DISK?". 3) Press th[...]

QUICK START 5 2) Send the MIDI exclusive files from the sequencer, syn- thesizer, or sampler. The display will tell you that it's re- ceiving the data. 3) At the end of the data transmission, the DATADISK will ask if the file is complete. Send more data or press the YES button to store all of the data received into one file. SENDING A SINGLE S[...]

SECTION 2 SECTION 2 DESCRIPTION OF CONTROLS FRONT PANEL 3 1/2" DISK DRIVE The disk drive accepts standard double sided, double density (DD) 3 1/2" floppy diskettes, the same as those used in many syn- thesizers, samplers, and computers. Each disk will store up to 53 MIDI data files as long as the total size of file data does not exceed a [...]

DESCRIPTION OF CONTROLS 7 BACKUP The BACKUP button is used to copy either a single file or multiple files of a diskette onto another for safety purposes. This is known as "Backing Up" the diskette. DO/YES The DO/YES button is used to initiate all operations of the DATADISK , and to select any choices which might appear in the display. The[...]

SECTION 2 BACKPANEL MIDI IN The MIDI IN jack is used to receive MIDI data from a sequencer, sampler, synthesizer, or effects processor for storage on diskette. MIDI OUT The MIDI OUT jack is used to send MIDI file data to a sequencer, synthesizer, or sampler. This jack can also be selected to function as a MIDI THRU jack so that it echo's an ex[...]

SECTION 3 SECTION 3 INTERFACING DATADISK DATADISK CONNECTED TO A SINGLE MIDI DEVICE Set-up of the DATADISK is simplicity itself. Simply connect the MIDI Out of the synthesizer, sequencer, effects processor, or other MIDI device that is to send system exclusive data, to the MIDI In of DATADISK . To off-load data, connect the MIDI Out of DATADISK to [...]

INTERFACING DATADISK 13 DATADISK USED TO STORE HR-16/HR-16:B, MMT-8 SEQUENCES In the setup shown below, DATADISK sends System Exclusive data to the HR-16, which has been set to echo System Exclusive information received at its MIDI Input and send it back out of its MIDI Output (see HR-16 manual for specific instructions). The data is then sent to t[...]

SECTION 3 DATADISK IN A MORE COMPLEX MIDI SETUP If you are using DATADISK with a number of other MIDI devices, you may wish to use a programmable MIDI patcher to route their MIDI inputs and outputs to DATADISK' s MIDI input and output. This will enable you to perform loads and dumps to and from any or all of your MIDI devices without having to[...]

DATADISK FUNCTIONS 15 SECTION 4 DATADISK FUNCTIONS THEORY OF OPERATION SYSTEM EXCLUSIVE DATADISK is able to work because the data is stored in the form of System Exclusive (or sysex) files. System Exclusive is the unique way that each manufacturer identifies its own particular data. This allows data from one manufacturers equipment not to be mistak[...]

SECTION 4 16 If the delay between messages is more than 1 second, DATADISK will store the next set of sysex messages in a new file. This is par- ticularly advantageous if you are saving an entire MIDI equipment system, where you would first send out your MMT-8 data, then your HR-16 data, then QuadraVerb data, etc.. In this case you would want each [...]

DATADISK FUNCTIONS 17 RECEIVE MIDI DATA FUNCTION The RECEIVE MIDI Data Function is used to store MIDI system ex- clusive data received from a synthesizer, sequencer, or effects processor to a floppy disk inside the DATADISK . There are two pages to this function which are: RECV ONE SYSEX Receive One Sysex (the display will read "RECV ONE SYSEX[...]

SECTION 4 18 DELETE FILE FROM DISK FUNCTION This function is used to erase unwanted files from a disk. There are two pages, which are: DEL NNNK: XXXXXX YYYYYY ZZZZZZZZ This page is used to delete (erase) a single file from the disk, where NNN is the size of the selected file in kilobytes (1024 bytes = 1K), XXXXXX is the manufacturers name of the fi[...]

DATADISK FUNCTIONS 19 BACKUP ALL FILES This page makes a Backup copy of an entire disk. During the Backup process, DATADISK will prompt the user when to insert either the original or Backup disk, and will indicate when the Backup is complete. BACKUP TO MIDI Rather than making a Backup copy of your data to a disk, it's also possible to send all[...]

SECTION 4 20 DISK INFO FUNCTION This button is used to display information about the diskette cur- rently inserted in the disk drive. There are 3 pages which are: XX FILES = ZZZ% YYY Kbytes free The information displayed in the first page is the number of files stored on the diskette (XX), the percentage of space used (ZZZ), and the amount of free [...]

DATADISK FUNCTIONS 21 RCV PROGRAM CHANGE Sometimes it is desirable to have a file send initiated during a se- quence or performance to change a program or sample. Even though DATADISK will receive MIDI system exclusive data on any channel, a single channel must be selected to receive a MIDI pro- gram change command. When such a command is received,[...]

SECTION 4 22 character set key until the desired character is displayed. These steps are repeated until all characters are changed as de sired. Pressing the DO/YES button stores the new name. DISK STATUS AND INFO MESSAGES DATADISK is an intelligent device and its display will either prompt the user to make decisions, or describe the current disk st[...]

DATADISK FUNCTIONS 23 DISK WRITE PROTECTED 3 1/2" disks have the ability to be write protected so that any data is not accidentally erased. This is accomplished by setting the tab on the lower right hand corner of the disk (when it is turned over) to the down position so that the window is open. Entering any function requiring disk writes (Rec[...]

SECTION 4 24 DUPLICATE FILE NAME This display occurs if a name is attempted to be given to a file that is the same as the name of another file. DUPLICATE FILE NAME MAXIMUM NUMBER OF FILES This display occurs if there are 53 files already stored on the disk. MAXIMUM NUMBER OF FILES NOT ENOUGH DISK SPACE This display occurs if there is not enough spa[...]

DATADISK FUNCTIONS 25 REPLACE FILE WITH SAME NAME?[...]

SECTION 4 26 TARGET UNIT NOT RESPONDING This display occurs when the Data Disk sends a file to an instru- ment that requires handshaking and receives no handshaking re- sponse. TARGET UNIT NOT RESPONDING PLEASE NOTE: There are safeguards to prevent against tricking the DATADISK by swapping disks before initiating an operation. For example: 1) With [...]

REAL TIME MIDI SEQUENCING 27 SECTION 5 OPER ATION DATADISK is easy to operate. First, the desired function is se lected by pressing the appropriate function button; then, if neces sary, the desired page is selected by pressing the same function button again. A file or parameter is then selected by pressing the SCROLL UP or SCROLL DOWN buttons. The [...]

SECTION 6 28 ** FORMATTING ** ** TRACK # XX ** The display will read from track 79 to track 00. XX is the current track being formatted. After DATADISK has formatted all 80 tracks, the display will briefly change to: ** CREATING ** ** DIRECTORY ** and then will temporarily display: FORMAT COMPLETE When formatting is complete, the display will retur[...]

When system exclusive data is detected, the display will read the following: RECEIVING XXXXXX YYYYYY In this display, XXXXXX is an abbreviation of the manu- facturer's name of the device sending the data, and YYYYYY is an abbreviation of the model name. If the data rec[...]

SECTION 6 30 RECV MULT SYSEX: WAITING FOR DATA DATADISK is now awaiting system exclusive informa tion. 2) Send a Sysex dump from the synthesizer, sequencer, effects processor, or other MIDI device. This may be called a "Bulk Dump", "File Transfer", or some other indi- cation that multiple files will be transmitted (check your ma[...]
