Hcard-702 (Yamaha DX7II-D/FD) |Compatibility|Order


Hypersynth multibank cartridge "Hcard-702" is specially designed for expanding the memory of the Yamaha DX7II synthesizer. DX7II voice memory is limited to 64 presets (1 bank), which could be upgraded to 128 presets by adding an external Yamaha "RAM4" cartridge. "RAM4" is discontinued, rare, and expensive and It relies on a battery for data retention. These flaws make it not a good choice for DX lovers in the modern age. "Hcard-702" can be used as a drop-in replacement for Yamaha "RAM4" cartridge, it stores up to 100 banks without the worry of battery life and data loss.



-Memory size: Up to 100 banks (6400 voices, 3200 perfs, 200 tunings, 100 setups).
-Instant access to different banks using touch buttons.
-Two digits bank indicator display.
-No need for a battery.
-Drop in replacement for Yamaha "RAM4" and "DATA ROM" cartridge.
-Up to 21 pre-programmed soundbanks.
-Hidden "Memory Protect" option.
-External display support for listing all 64 presets in the selected bank.
-Compatible with Yamaha DX7II, DX7s, DX11, RX7, and RX5.


Categorized SoundBank:

"Hcard-702" is loaded with default DX7II factory soundbanks plus 16 soundbanks which are selected carefully out of thousands of available free banks for DX7. These soundbanks are categorized in a way to simplify the workflow of the sound selection.


Additions and Fixes (REV.2):
