Sounds, sound formats

The sounds in the ddrum4 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, loading them via MIDI in two different formats, the

ddrum4 format and the MIDI Sample Dump format. Sounds in the ddrum4 format can be

accessed from our web site, free of charge. Point your browser to http://www.clavia.se/ for

more information.

ddrum4 sounds

A ddrum4 sound contains one or more samples that have been converted to a proprietary

format. It has been carefully compressed (by a factor of 3-6 times) and edited by the Clavia

crew. The compression technology allows the sounds to take up less memory so that we can

put more of them into the ddrum4. Each ddrum4 sound has a unique name, which assigns the

sound to its appropriate sound group. The sound numbers does not have to be consecutive. A

ddrum4 sound can also contain a couple of variations, which are different sets of functions

that affect the way the sound sounds and how it behaves when played upon. This is a set of

special parameters, not the ones that you can adjust yourself on the ddrum4 panel. One type of

variation function would be the crossfade information for multi samples or dynamic filter

settings.

Go see our web site and get free sounds

At our web site you will find all sounds as zipped MIDI files. Take them home with your web

browser and unzip them. Then you can load the MIDI files in to your favorite sequencer, and

download them to your ddrum4. 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.

MIDI Sample Dumps

A MIDI Sample Dump sound is a sample in another format that also can 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 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 ex-

change every single sound in the ddrum4!

These samples will not be compressed as much as the ddrum4 sounds (only by a factor of 2),

making them bigger than a corresponding ddrum4 version of the same sound, making the

transfer process slower. A MIDI Sample Dump has not the sound group identification data as

the ddrum4 sounds have, so 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 stand-

ard. Check your sampler for information regarding how it is numbering its samples. The ddrum4

will truncate these numbers to fit within the range of 1 to 999. A MIDI Sample Dump lacks the

special variations that the ddrum4 sound format has. But we have made it possible for MIDI

Sample Dumps to benefit from the variation functions. They are not as advanced as the ones

connected to the ddrum4 format sounds. Still, there are cool variations to check out on the

sample dump sounds.

If you start to make new drum sounds in a sampler, please remember that you have to edit

them in the sampler before you transmit them to your ddrum4. Make sure that the starting
