Some of you may have read about this four year old sound module. I decided to purchase this unit off eBay (girlfriend describes it as an old DVD player) because it was advertised as having great bread and butter sounds.

What I sorely miss is the sampling function. Perhaps one day Roland will add this sampling feature, that would basically make it a souped up Roland Fantom XR, with the 12 SRX modules built in as well as SuperNATURAL sounds.

This is not like any other review, it’s more of a look at the hardware itself. Opening up the unit we’re presented with a main control board along with the front end PCBs for the in/out jacks.

Note PCB footprint for a fullsized SD Card and additional 1Gbit Flash ROM.

USB

The main board is of great interest. It seems to have provision for 2x USB B and 2x USB A jacks. However only 1x USB B (USB MIDI/Audio) and 1x USB A (USB Memory) are exposed to the user.

I am interested to see what the other USB B port could be? A debug port? Who know’s for now, but when I have the right parts, I will solder a connector on and let you know in a future update.

ROM

The unit has 3x S29GL01 (1Gbit) GS10TF102 Flash ROM modules. That’s equivalent to 384MBs of information. I’m guessing this contains the Preset Waveform data. There are 256 SuperNATURAL Acoustic Tones and 1109 SuperNATURAL Synth Tones. If you compare thiswith the SuperNATURAL Expansions, each expansion has only around 12-50 tones.

Since each SRX expansion is 64MB is size, we can also guess that each SNx expansion is also 64MB.

There is also  MX29GL256 which is 256Mbit/32MB parallel flash. This could be used for the CPU Firmware and the User SVD patches, studio sets and other settings. However there are also a couple of other Flash ROM chips which could be used for this purpose

RAM

The unit has 8x IS42S16160D RAM modules which are 256Mbit/32MB in size, so the unit has a total of 256MB of RAM. Note that 2 of these modules are located on the underside of the board.

There is also another RAM chip probably used for the CPU which is a IS42S16400F which is a 64Mbit module or 8MB or RAM.

The ESC2 DSP looks to have 2x IS42S16160D (64MB) while the main CPU Rodgers Roland SSC has 4x IS42S16160D (192MB) assigned to it.

SD CARD

There is a 4GB microSD card on the unit, and for development purposes I believe there is space for a fullsized SD Card to be fitted on the underside.

I downloaded the contents of this SDCard, and the data starts at

0x00B7D7D0
0x30576BA0

Which is around 700-800MB or data, or 12x 64MB SRX Expansions.

Here is a link to the SD Card’s contents, however I am not responsible for any damage done to your unit.

I started the unit up without the SD Card and noticed that I could not load any of the expansion data, (Error Loading Expansion Message) but the Presets Tones were still available.

Overall it’s a decent device, but I don’t understand why they did not add the ability to load your own samples. It seems like the most powerful Roland Rack Module out there, with 256MB of RAM and the ability to pull information out of a USB Memory Key and potentially load it onto the SD Card, with 2x Mono Inputs on both the front and back means that the Integra7 is just crying out for SAMPLING features!

Please comment if you like this post and if you have any ideas for this module, let me know!
