Click here for lots of video's on Yamaha Electone EL-90 on YouTube!

An EL-90 is an open design with open space between the speakers and the pedalboard
An EL-90T is a cabinet housing
An EL-90I is white (Ivory)

An EL-90 can easily be disassembled into 5 pieces:

  • the upper part (2 screws under the keyboards, just in front of the speakers and 2 screws in the back between the upper part and the speaker part)
  • the speakers and amplification part (4 screws on the top and 4 screws behind plastic caps on the back)
  • two side panels (two screws each, on top of the pedalboard, under a plastic cap)
  • pedal board
Also the volume and expression pedals can easily be disassembled by removing only one screw.

The visible differences between an EL-90 and an EL-70 are:

  • EL-70 has 8 & EL-90 has 16 presets between the keyboards
  • EL-70 has 1 & EL-90 has 2 pedal voices
  • EL-90 has a second expression pedal
  • EL-90 has a bigger screen (same resolution!)
Less apparent differences are:
  • EL-70 has 79 & EL-90 has 131 voices (for instance panflute)
  • EL-70 has 4 & EL-90 has 6 speakers
  • EL-90 has better sounding voices
  • EL-90 has initial & after touch on the pedals
  • More software is available for EL-90
  • and some more

Disks
There are multiple types of floppy disks:
  • Registrations
  • Performances (and registrations)
  • Voices
  • Rhythm Patterns
Registration disks
The REGIST_MENU disks offer an easy way to select between up to 80 different registrations (5 pages of 16 registrations).
These disks contain a number of files, typical 2 or 4 files 17kB each for different Electone models.
  • RGM_35.DAT = EL-70
  • RGM_36.DAT = EL-90
  • RGM_3A.DAT = EL-57
  • RGM_3B.DAT = EL-40
  • RGM_3D.DAT = EL-50
  • RGM_3E.DAT = EL-60
  • RGM_43.DAT = EL-20/27
  • RGM_46.DAT = EL-500/700/900/900m
Electone models are downwards compatible. EL-900 will read RGM_36.DAT if RGM_46.DAT is not available.

Simply copy the files on a pre-formatted floppy disk and label the disk REGIST_MENU (in settings).
Here are the files of two common disks:

Performance disks
Performance disks contain a maximum of 40 performances.
Typical are disks with 10 to 30 performances
There are two file extensions: MDR_nn.EVT and MDR_nn.B00
Files with the extension .B00 contain registration information, user voices and rhythm patterns
Apparently sometimes there are specific registration files for specific models, for example .B36 for EL-90
Files with the extension .EVT (event) contain the key strokes
The EL-900 (and the EL-87?) can read an additional file called SONG.NAM and put it on the display
File numbering starts with 00 which corresponds with song number 01 on the MDR




Beware that I accept no responsibility for any problems that may occur when you read (and proceed) beyond this point





To put an EL-90 (probably the whole EL-series) in SELF CHECK MODE:
Hold down the C# Chord on the lower keyboard, starting with the second C# - while switching on the organ.
(This also displays the software versions)

Software versions I have ‘seen’ so far are:

EL-70: (C)'91/03/13 V.4.2(MAIN) V.5.0(MDRI)
EL-90: (C)'91/05/29 V.5.1(MAIN) V.9.0(MDRI)
EL-90: (C)'91/09/05 V 5.3(MAIN) V.E.0(MDRI)

I have no idea what the differences between these versions are.
Unfortunately software of the EL-x0 series can only be updated by replacing ROM's.
