High speed PCMCIA Flash 4mb memory card for storing samples, patches and mixes.
Compatible
with all Alesis QuadraSynth and QS-series synthesizers capable of
storing samples, including the Alesis QuadraSynth, QuadraSynth Plus
Piano, QS6, QS6.1, QS7, QS7.1, QS8, QS8.1 and QSR models. Normally used
with the Alesis SoundBridge software, to store up to 4MB of custom
samples and programs.
These SRAM cards feature a built in lithium ion battery that recharges
when inserted into a PC Card slot. Depending on the capacity of the
card, the batteries in these SRAM memory cards can go between seven to
twelve months before requiring recharge. These fixed battery models
have improved access times of 150ns and a broader range of capacities.
The cards are compatible with nearly all known PCMCIA
SRAM PC Card
applications and feature a write protect switch for preventing
inadvertent erasure. The card's rigid stainless steel construction
withstands harsh environmental conditions.
