Using the Wave RAM Option
The RMS50's wave RAM option lets you create a third source of waveform data, in addition to the RM50's
preset waveforms and those on the wave cards you insert in its three WAVEFORM slots. If you have
elected to instal! the SYEMB06 Expansion Memory Board in your RM50, you can copy waveforms from
wave cards to the wave RAM area, or dump them from another device as MIDI sample dumps, and then
use them to create completely new voices.
What Is Wave RAM?
Copying Waveforms From
a Card
The SYEMBO06 Expansion Memory Board is a 0.5 megabyte memory module
which is installed beneath the hatch on the RMS50's upper surface. The
installation procedure is simple: you remove the two screws securing the hatch
cover, insert the SYEMBO06 in the revealed slot, and then replace the cover. (Be
sure to read the instructions provided with the SYEMB06 before you attempt to
install it, as they include some important cautions which you should observe in
order to avoid damaging the SYEMBO06 or your RM50.)
Once you have installed the SYEMB06, your RMSO will possess an internal
wave RAM area capable of holding as many as 64 waveforms. The precise num-
ber of waveforms it can hold at any given time will depend on the size of the
waveforms you load to it. These waveforms are selected during the voice editing
process by choosing the internal (1) memory area in the Waveform Select func-
tion.
Do not forget that before you can use the wave RAM area, you must pre-
pare it to hold data using the Wave RAM Initialize function included in the
Wave RAM Utility group. This Initialize function is described briefly in the last
paragraph of this tutorial.
To copy waveforms into the wave RAM area, you must first insert a wave card
in one of the WAVEFORM slots on the RM50's front panel. Press the
[UTILITY] key to enter Utility mode. You will see a display showing the name
of a Utility mode function group, such as the one below.
You must use the [PAGE+] or [PAGE-] keys to scroll through the names of
the five function groups. You want to select the Wave RAM Utility group dis-
play shown below. (It is the fourth page of the Utility mode display.)

Press the [+1/YES] key to enter this utility group, then use the [PAGE+]
or [PAGE-] keys to select the second display page for this group. (Utility mode
display pages, like the Edit mode pages we have seen in previous tutorials, are
always selected using the [PAGE+] or [PAGE-] keys. Also, as usual, any
parameters in the display may be selected using the [>] key or the [SHIFT] and
[>] keys.)
