The sounds in the ddrum4 SE reside in a memory that is technically called a Flash ROM. This means
that besides storing sounds, you can delete sounds that you do not want and replace them with new ones.
The Flash ROM also retains its content when the power is switched off. You can load sounds into the
ddrum4 SE module via MIDI in two different formats, the ddrum4 format and the MIDI SDS (Sample
Dump Standard) format. Sounds in the ddrum4 format can be accessed from the Clavia web site, free of
charge. Point your browser to http://www.clavia.se/ for more information.

A ddrum4 sound contains one or more samples that have been converted to a proprietary format. It has
been carefully edited by the Clavia crew and finally compressed (by a factor 3-6 times). The compression
technology allows for the sounds to take up less memory so that we can put more of them into the
ddrum4 SE. Each ddrum4 sound has a unique name, which assigns it to the appropriate sound group.
The sound numbers do not have to be consecutive. A ddrum4 sound can also contain a couple of varia-
tions, which are different sets of functions that affect the sound and how it behaves when played back.
These special functions/parameters cannot be edited by the user. One type of variation function would
be the crossfade information for multi samples or dynamic filter settings.

At the Clavia web site you will find all sounds as zipped MIDI files. Fetch them with your web browser
and unzip them. Then you can load the MIDI files to the ddrum4Tool (PC) or to your sequencer, and
download them to your ddrum4 SE. Do not forget to download a copy of the factory sounds. This could
be very handy to have around, if you delete sounds and then change your mind.

A MIDI Sample Dump sound is a sample in another format that can also be transmitted via MIDI. There
are many devices that can transmit and/or load MIDI Sample Dumps. All you need is access to a sampler
or computer software with this capability. If you would like to have your own personally sampled sounds,
and have access to a sampler that can transmit sample dumps, you can exchange every single sound in the
ddrum4 SE.
These samples will not be compressed as much as the ddrum4 sounds (only by a factor 2), making them
bigger than a corresponding ddrum4 version of the same sound, and making the transfer process slower.
A MIDI Sample Dump has not the sound group identification data like the ddrum4 sounds have. There-
fore the MIDI Sample Dump sounds are placed in the Dump group in the ddrum4 sound memory. They
are numbered according to the MIDI Sample Dump standard. Check your sampler for information re-
garding how it is numbering samples. The ddrum4 will truncate these numbers to fit within the range of
1 to 999. A MIDI Sample Dump lacks the special variations of the ddrum4 sound format. But we have
made it possible for MIDI Sample Dumps to benefit from the variation functions. There are cool varia-
tions to check out on the sample dump sounds.
Note: For MIDI Sample Dump sounds, Variation #5 is a "mono trig" variation which means that any
new trig of the sound will automatically mute the previously played hit. This could be useful especially
for long decaying sounds. Please refer to
sounds.
