Wave Data Dump
If program data is being transferred between two VSs, it is important that
the same user waveforms reside in both machines. This does not mean
that program dumps will not be succesful if waveforms are not the same in
both machines, only that the two VSs will not sound the same. If that is your
intention, never mind. But if you want to back up your programs over MIDI,
then waveform dumps are essential.
1. To determine which waveforms you specically want to transfer, select the
desired program, then examine the Oscillator Group settings (or use the
Review function).
2. Press MIDI Options Select until the top line of the LCD reads "WAVE DATA
DUMP".
3. Select the desired wave number (0-31) or "ALL 32".
4. If necessary, prepare the other MIDI device for the transfer.
5. Press Enter.
RECEIVING WAVEFORMS FROM MIDI SAMPLERS
The Prophet VS accepts the MIDI Sample Dump Standard format (as
explained under the next heading), but only 128 12-bit words of wave data are
accepted per waveform. If a sample is sent with more data, only the rst 128
words are accepted.
To dump to the VS, you should truncate the sample so that the only thing left
is the desired sample loop. (If there is anything before the loop, it will become
the wave instead of the loop.)
If a sample loop is not exactly 128 words long, it will either be truncated,
or blank bytes will occur. In either case, the resulting VS waveform will be
dierent from the original. For the best conversion from a short sample loop
to a VS waveform, specic notes should be sampled. The note you should
sample is directly related to the frequency at which it is to be sampled:
Sample Rate Optimum Frequency Nearest Note
(Samples/Sec) (Cycles/Sec) (Even-tempered)
X X/128 B1 (123.4708)
15625 122.07031 B2 (246.9417)
31250 244.14063 E3 (329.6276)
41667 325.52084 E3 (329.6276)
