Sector101 SR-JV ROMulator Programmable Wavecard Overview
The SR-JV ROMulator card is an 8 Megabyte programmable Waveform Card for use with all the Roland series synthesizers that support SR-JV80 Expansion Cards.

The ROMulator card has been developed to allow experimental data to be used in a Roland unit. This will allow reverse-engineering to be performed on known-good SR-JV Expansion Card data. The goal is to unlock the data format of the Roland SR-JV cards and ultimately be able to create custom waveforms and patches that can be used in a Roland unit using the ROMulator card.

SR-JV Waveform Card Information taken from
The Roland JV-80, JV-90, JV-1000, JV-880, and JV-1010 synths from the JV series can be expanded with one SR-JV80 wave expansion board, as can the JD-990 and the Fantom FA-76.
The XP-30 and XV-88 can accept up to two SR-JV80 boards.
The XP-50, XP-60, XP-80, JV-1080, XV-3080, and XV-5080 can accept up to four SR-JV80 expansion boards.
The JV-2080 can accept up to eight SR-JV80 expansion boards.

ROMulator Card & Programmer Operation:
The ROMulator card is used along with the Programmer Unit to perform Read / Write / Erase jobs on the card.

The Programmer Unit plugs into a PC using the USB interface. The power for the Programmer Unit comes from the USB connection so no other power supply is needed.

To perform the tasks the Programmer Unit is controlled through a Terminal Emulator (Tera Term) application. The user enters commands through the keyboard and the Programmer Unit responds accordingly.

The Programmer Unit can also be used to backup data from SR-JV Expansion Cards. If an SR-JV card becomes faulty at a later date you can re-create the card using the ROMulator card.



Terminal Emulator Interface:
The example below shows the Programmer Unit's responses to one of the commands.
The top part of the screen is the normal boot title when the Programmer Unit is plugged in.
The CD command asks the Programmer Unit what type is card is installed on it.
The first response is where the ROMulator card was plugged in with data already programmed in to it.
The second response is where the original Roland Techno SR-JV card was plugged in.

The Tera Term Terminal Emulator application is included in the ROMulator Software Pack ZIP file.

ROMulator Cards installed in JV-2080:
