YesXR (Yamaha Electone Simple SysEX-Recorder) is a free/libre and open Project (GNU GPL v.3) which targets the owners of the ‘vintage’:
– Yamaha ELECTONE Series (MIDI organs) marketed worldwide between ~ 1986 and 2001, and
– Yamaha Music Disk Recorder (MDR) device peripherals marketed worldwide between ~ 1986 and 1996.
This version of YesXR (here a shell script with GUI using YAD) ‘should run’ under any free/libre GNU/Linux operating systems such as:
– ARCH Linux & all their derivatives-flavors like Manjaro Linux, Endeavour OS and even Manjaro-Arm,
– DEBIAN & all their derivatives-flavors like Ubuntu, Linux Mint, MX Linux, Pop!_OS, Elementary, Deepin Linux, Zorin and even Raspberry Pi OS (Arm),
– RED HAT & all their derivatives-flavors like Fedora and others,
– SUSE & all their derivatives-flavors like openSUSE and others,
…and…
– Surely much more distributions.
♦ Presentation
YesXR -a MIDI SysEx utility software- is handling the ‘All-RAM Data’; i.e. Registrations & other Non-Performance Data- of the compatible Yamaha ELECTONE ‘vintage’ Series.
It can be used as a partial replacement or substitution of the Yamaha ‘Music Disk Recorder’ peripheral devices (MDR-2 / MDR-3 / MDR-4 / MDR-10) designed exclusively for Electone use, -but their file formats are not compatible!-.
Overview of ELECTONE’s All-RAM = Registration & other Non-Performance Data
This applies to both ELECTONE <==> YesXR -and- MDR ==> YesXR transmissions
- Data memorized at the Registration Memory (#1-to-8 or #1-to-16)
- Data of the Current Registration Memory
- Internal Sequencer (iSEQ) data or Full Music Programmer (F.M.P.) data
- Data of the Chord Sequence Programmer (C.S.P.) / Rhythm Sequence Programmer (R.S.P.)
- Data of the User Rhythm Patterns (U.R.P.1) or User Rhythmic Patterns (U.R.P.2)
- Data of User defined Voices (U.V.)
- For the Specific List of All-RAM data which can be recorded, please consult the User’s Guide or Owner’s Manual of your Yamaha Electone Series / Model.
Note: ‘Yes-XR’ is not designed for recording Electone Live Performance data -but- the future ‘Yes-MDR’ should do it!
• Minimum screen resolution
The Control Panel of YesXR has a fixed resolution of 960 x 520 pixels (17:9 ratio).
Thus, a minimum screen resolution of 1,024 x 768 pixels (XGA – 4:3 ratio) or 1,280 x 800 pixels (WXGA – 16:10 ratio) is highly suggested. A 1,920 x 1,080 pixels screen resolution (HD1080 – 16:9 ratio) will be ideal.
NOTE: The visual appearance of YesXR can slightly vary across the GNU/Linux operating systems (few hundreds currently available with few dozens of main distributions). The GUIs aspect of YesXR are influenced at least by the following used elements: YAD (Yet Another Dialog) & GTK+ (Widget Toolkit) versions, Desktop environment (Gnome, KDE Plasma, Cinnamon, MATE, Xfce, etc.), Theme (use dark one’s!) and System Font characters (types and sizes).
• YesXR -a GNU/Linux MIDI utility software- allows you to easily
- Record/Save ‘All-RAM’ Data from your Yamaha Electone’s RAM to your GNU/Linux PC’s Disk.
- Load/Send back these ‘All-RAM’ Data from your PC’s Disk to your Yamaha Electone MIDI organ.
- Backup/Save ‘All-RAM’ Data stored on your Yamaha MDR’s storage device (song by song) to PC’s Disk.
- Display ‘MIDI Traffic’ in HEXAdecimal for System Exclusive (SysEx F0h, …, F7h) Data and even Any MIDI Messages.
- YesXR is compatible with at least the Yamaha ELECTONE ‘vintage’ CHX / HX / HS / US / HE / HC / EL Series. See the complete list of the ~ 40 Organ Models at the bottom of this article.
- This is achieved by handling dedicated MIDI (Musical Instrument Digital Interface) System Exclusive Messages (ELECTONE / MDR common messages — BULK DUMP related messages (F0h, 43h, …, …, …, …, …, F7h):
- Request-ELECTONE-to-Send All-RAM-data,
- Request-ELECTONE-to-Receive All-RAM-data, and
- Request-MDR-to-Send All-RAM-data (storage device).
YesXR is a lightweight portable utility software. Thus, it can be used from either an internal disk (HDD or SSD) and/or an external one (USB stick, USB storage or SD Card).
• To run successfully YesXR
- The following 3 software packages must be installed in your GNU/Linux operating system:
- Alsa-utils v. ≥ 1.2.2 used for the communication between the MIDI Devices; i.e. Yamaha ELECTONE organ / Yamaha MDR peripheral / MIDI/USB Interface & PC,
- YAD v. = 0.40.x or ≥ 10.1 used for the GUI (graphical user interface) dialogs, and
- Gnome-terminal v. ≥ 3.36.2 which is only needed for the [MIDI MONITOR] operation.
- If they are not installed yet, depending of your GNU/Linux experience, this can be done from:
- the Software Center / Manager – a GUI utility for easily exploring, installing and removing software in your preferred distribution (see below screen capture), or
- the Command Line in a Terminal; e.g.:
– Debian & derivatives (Linux Mint, Pop!_OS, Ubuntu, etc.): sudo apt install <application_name>
– Arch Linux & derivatives (Manjaro, Endeavour OS, etc.): sudo pacman -Syu <application_name>
- The script’s GUI is using the Theme of your Desktop environment. Make sure to use a ‘Dark’ system Theme for allowing a good readability of the Control Panel and the user messages.
- The Testing Terminal is now only used on-demand for displaying potential issues when using YesXR.
‘YAD‘ – Yet Another Dialog / Display GTK+ dialogs from shell scripts or command-line — An improved fork of Zenity program
- YAD is a utility program that will display GTK+ dialog boxes, and return (either in the return code or on standard output) the user’s inputs.
‘Alsa-utils‘ / Advanced Linux Sound Architecture – Utilities
- This package contains the command line utilities, including MIDI, for the ALSA project.
‘Gnome-terminal‘ / A Terminal emulator for GNOME and All UNIX compatible Desktop Environments.
- This package contains the program that emulates a console in a graphical interface. It allows you to launch commands and visualize outputs.
♦ ‘Yes…’ Future versions
• YesXR — Yamaha Electone Simple SysEx Recorder project with Yad & Alsa-utils
- Future releases should be mainly for maintenance purpose.
• YesMDR — Yamaha Electone Simple Music Disk Recorder project with Yad but Alsa-utils ?
- YesMDR will be an upgrade of YesXR (All-RAM Bulk Data Dump; i.e. Registrations & other Non-Performance data, and MIDI Monitors).
- Add Live ELECTONE Performance: Record & Playback
- Add Backup MDR Performance; i.e. similar to MDR’s Custom Playback.
- YesMDR could replace (more or less) the Yamaha Music Disk Recorder peripheral devices (MDR-2 / MDR-3 / MDR-4 / MDR-10) designed exclusively for Electone use, -but- their file formats will not be compatible neither for the Bulk Data Dump nor for the Live Performance.
- NOTE: The YesMDR project is delayed due to the fact that the Alsa-utils are not providing the expected features in the area of Live Performance. Currently several other MIDI command-line utilities (like MidiSh, ReceiveMidi/SendMidi and others) are under investigation for properly handling MIDI Live Performance as well as Bulk Data Dump (All-RAM) and MIDI/USB Interfaces.
♦ YesXR OPERATION — ‘YAD’ version
To make the use of YesXR (Yamaha ELECTONE Simple SysEX-Recorder) as easy as possible its operation is automated as much as doable.
• CONNECTING your MIDI DEVICES together
- FIRST: You must properly connect your compatible Yamaha ELECTONE and/or your Yamaha MDR to your MIDI/USB Interface·s (much better and easier if Class Compliant I/F) to your GNU/Linux PC.
- Note: Without at least one MIDI/USB I/F connected to and recognized by your PC, you will not be able to use – explore the functionalities of YesXR!

• MANAGING -Bulk Dump- Files
- Since v.0.1.70: YesXR is now properly handling ‘white spaces’ in both directory/folder and file names.
- Since v.0.1.52: YesXR is also using the System File Manager for [Backup-mRam] operation.
- Since v.0.1.33: YesXR integrates the System File Manager for both [Record-eRam] and [Send-eRam] operations.
- The name of File.ext (binary file!) can be freely chosen by the performer.
For the .ext, it’s best to use specific extension dedicated to YesXR (Yad); e.g. .eram/.mram or .xram/.zram. This will allow you to easily handle different versions of your recorded / backed-up files for building your ELECTONE’s / MDR’s ‘All-RAM’ library with YesXR.
* YesXR v.0.1.80 — Quick presentation — ‘YAD’ version *

– Last ACTION done: [ BACKUP All-mRAM / MDR-to-PC ] = Status, and
– Last FILE used: Path/Filename.ext of xyz bytes.
Note: The time required to backup All-RAM data will vary with the type of data which was originally recorded by the MDR model from the ELECTONE model / series. This can take from just few seconds up to several tens of seconds or even more (especially if SEQ or FMP data were recorded).
• 5- [MONITORING] – MIDI Traffic in HEXadecimal Bytes or Human Readable TEXT
- TEXT Monitor: available since YesXR v0.1.85.
- HEX Monitor: available since YesXR v.0.1.80.
- Make sure you have previously selected the right MIDI/USB I/Fs connected to the MIDI Device you want to monitor! These devices could be of course a Yamaha ELECTONE or a Yamaha MDR, but also any other MIDI peripherals from any brands.
- On the YesXR Control Panel window, click on the [MIDI MONITOR] button.
- A Choice/Selection window appears giving you the choice between HEX Bytes Monitor or Readable TEXT Monitor. Once your choice is made, click on either the HEX or the TEXT button. This will open accordingly a dedicated Gnome Terminal.
- Each MONITORing Terminal prints/displays the MIDI Data (System Exclusive and/or Any MIDI messages) received from the selected ALSA MIDI-IN port as HEXAdecimal Bytes or Readable TEXT.
- If needed, you can Copy/Paste its output to a Text editor or an Hexa editor for an easy reuse.
If the length (at the beginning) of the output is truncated, increase in the Gnome Terminal’s Preferences the max. number of lines value of the history.
Note: You can use both HEX & TEXT MIDI Monitors as a learning / debugging tool. It can display from small to large Manufacturer System Exclusive data (F0h, IDh, …, …, …, F7h). You can also discover Yamaha specific SysEx messages (F0h, 43h, …, …, …, F7h) sent by the ELECTONE when pressing on any specific buttons on the organ. For Electone’s buttons and commands which are part of the MIDI v.1.x specification, e.g. Notes (channel, number, velocity, aftertouch), Program Change (PC) and Control Change (CC), these 2x Monitors will display their MIDI values (either in Hex Bytes or Readable Text).
• ERRORs Handling
- No MIDI/USB Interface ‘Detected’ or ‘Selected’!
The above YesXR — Errors! windows can be displayed after having clicked on the [MIDI/USB I/F], [RECORD-eRAM], [SEND-xRAM], [BACKUP-mRAM] or [MIDI MONITOR] button. See above 1- [SELECTING] MIDI/USB I/F. No CHOICE -or- Unexpected ERROR!
⇒ It has been removed since v.0.1.85 and replaced by improving the internal operation of YesXR.
If No CHOICE was confirmed by the Performer on the Control Panel window or a Dysfunction has occurred, the above YesXR — Oops! window is displayed and the program is quitting after a 5 seconds countdown progress bar.
* YesXR v.0.1.80 — Errors & Warnings windows — ‘YAD’ version *
Since v.0.1.80: YesXR is now warning the Performer when No File.ext was typed or selected and when the File.ext size is 0 KB (i.e. empty). This is applying for all three [RECORD-eRAM], [SEND-eRAM] and [BACKUP-mRAM] operations.
• DEBUGGING / TESTING YesXR
