The PRESET, INTERNAL
Here's a global view of the SY55 system:
and CARD Voice Banks
Please note that the voices played by the SY55 can come from three differ-
ent sources: the PRESET voice bank, the INTERNAL voice bank, or a CARD
voice bank:
PRESET
The PRESET voice bank contains 64 pre-programmed voices in ROM
(Read Only Memory) that cannot be overwritten or changed in any
way. The PRESET voice bank is represented on the display by the
letter "P".
INTERNAL
The INTERNAL voice bank is a RAM (Random Access Memory) area
into which you can store up to 64 voices that you create or load from
an external memory card. The INTERNAL voice bank is represented
on the display by the letter "I".
CARD
The CARD memory bank is a YAMAHA MCD64 or MCD32 Memory
Card (or pre-programmed voice card) plugged into the SY55 DATA
card slot on the front panel. Memory cards are convenient for external
storage and transportation of voices that you or others create. You can
also store sets of related voices on different memory cards. An MCD32
Memory Card allows storage of up to 64 voices. An MCD64 Memory
Card holds two banks of 64 voices each — a total of 128 voices per
card. The CARD voice bank is represented on the display by the letter
"C" (the second bank of MCD64 cards is represented by a reversed
"C").
