*Q2400: Memory Expansions

There are several ways to increase the SY99 memory:

	SYEMB Memory Expansion (Q2410)
	MCD64 Memory Card (Q2420)

*Q2410: SYEMB Memory Expansions

Up to five SYEMB-05 Memory Expansion Boards may be installed to increase the amount of available Sample RAM / MDR RAM. SYEMB Memory Expansions are designed to be very user-friendly.

To install the memory expansions, remove the "SY99" labeled cover on the rear side of your SY99. Follow the instruction manual included with the memory expansion board to upgrade your internal RAM. The amount of MDR value can in no way exceed 512K.

SYEMB Memory Expansions	MDR size	sample size
none (only basic 512K RAM) none (only basic 512K RAM)	0 K 512 K	512 K 0 K
1 (basic 512 K + 512 K) 1 (basic 512 K + 512 K)	0 K 512 K	1.024 K 512 K
2 (basic 512 K + 1.024 K) 2 (basic 512 K + 1.024 K)	0 K 512 K	1.536 K 1.024 K
3 (basic 512 K + 1.536 K) 3 (basic 512 K + 1.536 K)	0 K 512 K	2.048 K 1.536 K
4 (basic 512 K + 2.048 K) 4 (basic 512 K + 2.048 K)	0 K 512 K	2.560 K 2.048 K
5 (basic 512 K + 2.560 K) 5 (basic 512 K + 2.560 K)	0 K 512 K	3.072 K 2.560 K

*Q2411: SYEMB Memory Expansion Types

Type	may be used with
SY-EMB05	SY-99
SY-EMB06	SY-85, TG-500, RY-20, maybe RM-50

If your unlisted synthesizer supports SYEMB memory expansions, please submit name and manufacturer of your synth to the FAQ maintainer

*Q2420: MCD64 Memory Card

Generelly, MCD64 Memory Cards are RAM cards that can be used to store patches, multi setups, synth setup, sequencer data or other type of user data. MCD-64 Memory Cards may be used by different synthesizers (see incomplete list below).

For the SY99 (and probably the SY77 / TG77 too) you can only store one patch bank (Card) or other types of synth data. Other SY- and TG-synths (such as the 22 / 33 / 35 / 55 series) will save two patch banks )

It is said that the MCD-64 stores up to 64 KByte whereas the MCD-32 stores only 32 KByte of data.

The MCD-32 Memory Card is NOT compatible with the SY99.

*Q2421: MCD Memory Card Types

The following table might give you a first impression about possible combinations between MCD Memory Cards and synthesizers:

Card Type	may be used with
MCD-32	SY-22, TG-33, SY-35, SY-55, TG-55, YS-100, V-50, B-200, RX-8
MCD-64	SY-99, V-50, some other synths of the SY- / TG- / RM series

If your unlisted synthesizer supports MCD Memory Cards, please submit name and manufacturer of your synth to the FAQ maintainer

*Q2430: Missing SIMM support

Unlike the Yamaha SY85 Synthesizer, the SY99 does not seem to handle single inline memory modules (usually referred to as 'SIMM').

It is said that the SY85 can handle 30pin / no-parity / 80ns SIMMs. If you have an SY85, make sure you reinitialize the memory of your SY85 after SIMM installation, otherwise the RAM may not be accessed.

*Q2440: Third Party Memory Expansions

Musitronics in Germany sells expansion boards up to 8MB (Thanks to Zelimir for pointing this out).

If you know of other expansion solution not mentioned in this FAQ, please drop a mail to the FAQ maintainer.
