BASIC TERM S AND KEYW ORDSMI D l-related terminologyHere wcdcfine several basic terms used in this ttuuuu: I. These terms are frequentlyused in descrihing (he functions ofM/Of equipment.

An abbreviation for Musical InstrumentlJigita I Interface, which is the name of aninternational standard providing for thecornrnunication of data between elec-tronic musical instruments. MIDI allowsmusical instruments such as synthesizersand drum machines tocomrnunicatewitheach other, and to be controlled by sc-quencers or computers.Any piece of electronic equipment ca-pable of receiving or sending data in amanner that complies with the MIDI stan-dard. This term is often applied to synthe-sizers, tone generators, rhythm mach ines,and sequencers: however, it also includesa variety of peripheral devices includingsignal processors and patch bays, not tomention MIDI data recorders such as theMDF2.Data in a format that complies with theMIIJI standard. MIDI data can be dividedbetween two broad categories: sequencedata and bulk data.

The data used to record an d pl.ly backmusic. Generally speaking, sequcnccdata consists of note on and off messages,cOIl.lrol change rnessages,. and. programchange messages. In special cases, how-ever, it may also include certain types ofsystem exclusive data.Data transmitted in units known asblocks,usually for the purpose of storage or re-trieval. Each MIl)l device usually trans-mits bulk data in ;) unique format thatdisl ingui shos it frorn Ihe bulk data of otherdevices; thus. it I s also known by thename "system exclusive data". f)ulk datais usua Ily not directly related 10 a musicalperformance: rather, it isused as ,Imeanslo r transferring large blocks of data, suchas voice data, samples, or system setup ('data, between two MIDI devices.A tr.msmission of bulk data from oneMI lJl device to another.

Thel.,)" 2LJLJ floppy disk is a rei iable and convenient medium for data storage, capable of holding largearnou nts of data in a small package. The disk itself is a del icate piece of magnetic film, wh ich is protected (.,.(rom dust and din by a hard plastic cover and a shutter. Thisdcsign iscapable oj preserving your data against 'most contingencies_ However, for the greatest reliability, you should observe a few basic cautions whenhandling your disks. Use only 2DD disks. The MDF2 is not designed to handle disks meeting other specifications. Never remove ad iskfromthediskdrivcwhilcthc disk access LE D is Iit. Doingso GHl damage the floppy

disk or the disk drive. Avoid touching the shutter of a disk. Never open the shutter and touch the actual disk surface. Avoid placing disks close to speakers, televisions, magnets, or other objects wit h mdgn(~t ic fields. Even

weak magnetic fields can damage or erase the data on a disk. Do not leave your disks in cars or other loca: ions where they mdY be exp()sed to r:xt rerTl(' heat or cold. Do not loavo your disks in places where they may be exposed to ondonsation or extremely high

humidity. Avoid using or storing disks in places where they may be exposed 10 large amounts of dust or dirt.follow these cautions scrupulously. Improper handling can render a disk useless, and may cause (,damage to the MDf2's disk drive as well.

MDRMoDfIn its MIDI data recorder (MOR) mode, the MOF2 is capable of receivingMIDI bulk data from nearly any MIDI device and saving it to disk asan MORdata file. It can then transmit this data back to the device that originated it;J 'I, or to any other device capable of accepting the data, at any time.Receiv ing bu l k dat aThe bulk data reception function is used to receive bulk data sent from anotherMIDI device. The MDf2 automatically writes the bulk data it receives to disk asan MDR data file using Standard MIDI Fileformat O. You can save up to 99 MDRdata files on a single disk.

IT r ansm it ting b u l k dat aThe bulk data transmission function lets the MDF2 output the data which it haspreviously saved asan MDRdata fileto a MIDI dcvicecapableof receiving it. TheMDF2 is also able to transmit the data from files created by the Yamaha QX3 inthat device's MlW mode.

Notes on MIDI Synchronization

8/4/2019 MDF2E

44/75

The MIDI clock of a sequencing device to be synchronized with the MDF2 mustnormally be set to a value opposite that of the MDF2. If you want the MDF2 to controlthe playback tempo, select the "int." sync mode and set the other device to use theMIDI clock. If the other device is to be the master, reverse these settings. In eithercase, you should also use the "MIDI control" function to enable the MDr2'stransmission and reception of MIDI system control messages. When synchronizingthe MDr2 to another device, both the "Sync mode" and "MIDI control" functionsmust be set to appropriate values.The possibilities for combining these settings are summarized in the table below.

Caution: Ifan external sequencer or other device connected tothe MDF2 retransmitsthe MII}I data it receives (using a MI{]I echo function), avoid a looped MIDIconnection or set the MU{2's MIDI control function to //0((". Otherwise, the MDF2may malfunction.

THE STANDARD MIDI FILEAND ESEQ FORMATS

8/4/2019 MDF2E

56/75

The Standard MIDI File format is a sequence data filetormat wh ich has been adopted by C 1 number of sequencingsoftware products for the IBMC~IPC!ATIM and compatibles,the App Ic(ii) Maci ntosh!'", and a variet y of other computers.There arc actually two Standard MIDI File formats: Format 0records all sequencer data for channels I through 16 as asingle track, whereas forrnat 1 provides for an unlimitednumber of tracks, each including data for one or rnorechannels.

Ihc ESEQ format is a sequence file torrnat particular toYama ha products. Th isformat isused by a nurnberof popu larYamaha sequencing devices. such as the QX3 and the built-in sequencers of the SY99 and SY77 Music: Synthesizers.The MI)F2 writes its SEQ data files using Standard MIDI Fileformat O. It is capable of playing back files written by otherdevices in this format, as long as they arc stored on a diskwhich the MDF2 is capable of rcading.

Morcover, the MUF2 CcHl play ESEQsequence files while inSEQ mode. It distinguishes between standard MIDI files and[SEQ files by checking the file header. No conversionprocess is required to play back ESEQ files.

54

If you will usc the MDF2 to play sequence files recorded byother devices, be sure to keep these files and your MDF2 SEQIi leson separate disks. (There is one exc(..pt ion to thisrule: the., 1SY99 can usc your MDF2 data disks to record songs in thq ,Standard MIDI File format. The MDF2 will treat such files asif they were SEQ fi les it had recorded itsclf.)When you place a disk containing only nOll-SEQ files in theMDF2, it will display the full filename (including the exten-sion) of each file. Should you mix SEQ files together withother sequcncefiles on c 1 single disk, however, the MDF2 willdisplay the names of the SEQ IiIt's on Iy, rna king it impossibleto play the other fi k-s. HCIlCl' the need to keep SEQ Ii IE'Sandnon-SEQ files on sepdratc disks.If you have a personal computer, you Gill trick the MDF2 intoplaying back [SEQ files (or standard MIDI files created bydevices other than the SY(9) which you have saved on diskscontaining SEQ files. To do so, you must lISC your computerto change the filename extensions of the non-SEQ files. Themethod for accomplishing this is described in the f()llowillf!~pages.

ADVANCED FILE MANAGEMENT TECHNIQUESReading MDF2 Disks with a Computer

8/4/2019 MDF2E

57/75

The disks you format for use with the MDF2 are compatible with MS-DOS'"or PC-DOS'''. This means that you can read the data from your MDF2 diskslusin,ij an IBM" PC/AT"-cornpatihle computer. Conversely, theMDF2 will becepablc of reading data from 3.5" 2D[) disks formatted hy an IBM PC/AT.Hint: T he A ta d'" Sf" a nd A pple" M acintosh'" a re a lso ca pa ble ofrea ding cla ta F rom disks toim ancd by the M UF 2. I f you own aM acintosh, usc a utility progra m such a s A pple F ile E xcha nge orD OS M ounter'" to rea d the da ta from your M DF 2 disks.

Try inserting an MDF2 disk into the disk drive of your PC thendisplay a directory of the disk's contents. You will sec a displaysomething like the following:

As you can see, eac h of the M DF 2 fi lenames is followed by athree-character "extension". The MIJF2 uses these extensions toorgan ize the fi les on its disks.Extensions beginning with the letter "8" indicate that the file inquestion contains MIJR data, whereas files bearing extensionsbeginning with the letter "X" contain SEQ data.The second two characters of each extension indicates the filenumber by which the MIJF2 refers to the file. Thus, MDR data fi I enumber 01 would have the extension ".801", whereas SEQ datafile number 01 would have the extension ".X01 ",If you desire, you can usc your computer to change theseextensions. Doing so will make possible some "tricky" applies-tions that you normally cou Id not ach ievc using the MDF2 alone.Some examples are given on the next page.

Changing MDF2 Filename Extensions

8/4/2019 MDF2E

58/75

Here are a few examples oi advanced techniques that become possiblewhen you usc a computer to change the extensions of your MOF2 tiles. Ityou arc usin,q a DOS-based system, you can change extension using the"ren.unc" (or "rcn") tutiction.Reordering songsYou will rcull that when se t you the "Repeat play" function to",\ II", the MI)[.! wi II pldY har.k oach of the SEQ data files on a diskIn order. Now, imagi 11(' that you have recorded a number of SEQhies to d disk, an d suddenly decide you want to play the first andsecond fi l es in the opposite order.You could change their order using the "Append" and "Delete"functions; but this would be pretty troublesome. Itwould be mucheasicr to simply insert the disk in your computer, change theoxtc-nsion 01 file 01 to ".X02", and then change that of file 02 to".X() I ", When you put the disk back in the MI)F2, the songs willhav changed place Justas if you had gone through the trouble ofIlloving them.

Caution: WhclJ you are renaming iile, be careful not to give twoor more tiles the same extension. Ifyou do so, the MDr2 will onlyhe able to {('.lei one' o r the files.
