Description

YRM-506

The YRM-506 (YRM-56 in Japan) FB-01 Voicing Program is one of the programs developed by Yamaha that allows to use his MSX1/MSX2 CX computers to program voices for another Yamaha device. Here's the sofware dedicated to the FB-01 FM Sound Generator, it was released in 1986.

This software is very similar to the YRM-502 FM Voicing Program II, the explanation is simple: the FB-01 is actually a standalone SFG-05, coming with 5 banks of 48 voices in ROM for a total of 240 voices, and 2 other banks are available in RAM to create 96 user voices. Besides, its memory can be configured (4 presets in ROM and 16 user memories in RAM).

When using the YRM-506 cartrige, the voice data and function parameters from the FB-01 device are visualised on the MSX screen for a bank of 48 voices, they can be edited and new voices can be created. The FB-01 configurations can also be visualised and modified.

All data, parameters and configurations can be saved on disk, cassette tape or Data Memory cartridge UDC-01, they can be sent from the CX computer to the FB-01. As the voice format of both devices is almost the same, the edited voices and new voices can also be later used on the CX computer, only a few parameters will be ignored, it happens only when a specific parameter is not used on both devices.

Screens

After the intro screen, you will land on the Command menu of the Voice editor. Enter CON on the command line to go the Command menu of the Configuration editor. You need to enter VOI to go back to the Voice part of the software.

Going to the editor is made by F1 and the same key allows to switch then between the editor and the command line. Each editor has its own Directory (enter DI on the command line). There are different Key lists, accessible by F5, and a common Load/Save menu (enter TR on the command line).

The command line is available on all screens, except the Key lists. The main commands can't be entered on the Load/Save menu screen, while the specific Load/Save commands are only available on this special screen.

Command menu (HE)

YRM-506 Voice Command menu
YRM-506 Configuration Command menu

The screen of the Command menu is divided into 3 parts:

- a command line on which you can enter different commands

- the list of the main available commands

- the explanation of some abbreviations

Command menu in voice editor

Voice number can vary between 1 and 48.

The green point on the line under the command line indicates the split point of the music keyboard between instrument 1 used in polyphonic mode for the editing keyboard and instrument 2 used in monophonic mode for the comparison keyboard. By default, this point is set at the lowest key, so it means that all keys are used for the editing keyboard.

To change the split point, you need to press SELECT, then a key on the music keyboard. The keys at the left of the green point will be used for the comparison keyboard. The current voice data are set for this keyboard by pressing F4 in the Edit mode.

Command menu in configuration editor

A MIDI connection with the FB-01 device is required to access to the different screens of the configuration editor.

The commands are almost identical to these available in the Command menu of the voice editor.

CON is replaced by VOI to go to the Voice editor and parameters n and m are used for configuration numbers instead of voice numbers, they can vary between 1 and 20.

Available commands

Command Meaning
n voice or configuration number n Select voice n and go to Voice or Configuration Editor
CON CONFIGURATION Go to the Configuration Command menu
COP n, m COPY voice or configuration number n, voice or configuration number m Copy data of voice or configuration n to voice or configuration m

TR TRANSMISSION OF DATA Go to the Load/Save menu
VOI VOICE Go to the Voice Command menu

Directories (DI)

YRM-506 Voice Directory
YRM-506 Configuration Directory

The screen of the Directory is divided between the command line and a list of all of the names and numbers of the voices or configuration, stored in the computer memory and generally coming from a bank of the FB-01 device.

This list can be different after loading of created voices or configurations from disk, cassette tape or data memory cartridge.

Voice Directory

This Directory displays the list of 48 voices.

(Note that the screenshot has been made on an emulator, without connection to a FB-01 device)

Configuration Directory

This Directory displays the list of 20 configurations: only configurations 1 to 16 can be edited and saved. Configurations 17 to 20 are presets in ROM memory of the FB-01 device, you can eventually test changes on these configurations, but you can't save the modified configurations.

Voice Editor (VOI, F1)

YRM-506 Voice Editor

The screen of the Voice editor is divided between the command line (access by pressing F1) and 5 blocks allowing to make a fine editing of the currently displayed voice.

General settings are in the first block, specific settings for each operator of the digital FM voice generator are in the 4 blocks with number 1 to 4. The cursors are useful for selecting a parameter. To modify it, just type the new value and press RETURN, or use the (INS +) HOME or DEL keys.

Each of the 4 operators can be switched ON/OFF by pressing CTRL + one of the keys 1 to 4 corresponding to this operator. You can also move the cursor over the operator number and type in a different number to turn it OFF or the correct number to turn it ON. Instead of typing a number, you can also use the HOME and DEL keys.

Configuration Editor (CON, F1)

YRM-506 Configuration Editor

The Configuration editor is divided between the command line (access by pressing F1), general settings and specific settings for each instrument.

Each configuration uses 8 instruments (one note per instrument, each voice can produce a maximum of 8 notes). Some parameters are common with the Voice editor; in this case, the values used in a configuration override the corresponding values for a specific voice, as defined in the Voice editor.

The cursors are useful for selecting a parameter. To modify it, just type the new value and press RETURN, or use the (INS +) HOME or DEL keys.
