PCM 81
PCM 91
The PCM 81 and PCM 91 are each equipped with an industry-
standard PCMCIA card slot, allowing users to store personal
programs and setups on RAM cards. For the PCM 81, adding
Lexicon’s Dual FX algorithm and specially designed preset cards for
the PCM 80 (all of which are compatible with the PCM 81) increases
its number of algorithms to more than 40 and its number of presets to
nearly 800.
