Drum Kits and the Tone Generator
A drum kit is a collection of drum voices (from 1757 different ones) assigned to pads (trigger
inputs) and which have been tuned, assigned reverb settings and so on. You could set up
different drum kits for different genres of music. A drum kit consists, essentially, of separate
sections for triggers, voices, effects and MIDI setup, holding all the parameters from trigger
input to voice output. When you select a drum kit, the data for all these parameters are
copied to the edit buffer and used for performances (see above the illustration).
There are various Voice Edit parameters that allow you to tailor sounds to your liking, such
as to change the pitch of a voice or the amount reverb applied to it.
There are 90 types of Preset Drum Kits (P1 to P90). You can also store up to 40 User Drum
Kits (U1 to U40) containing drum kits that you have set up and edited. A further 99 kits can
be saved to Memory Card (C1 to C99).
With the Chain feature, you can line up a series of different drum kits and call them up in
order during a performance. This can be useful when playing live.
Furthermore, aside from its drum voices, the DTXTREME also has a variety of 128 keyboard
voices which can be used in DTXTREME songs as melody or accompaniment instruments.
The tone generator is 64-voice polyphonic and compatible with the GM sound set. Therefore,
it can be used to play back generally available GM-compatible MIDI files as well as MIDI files
created using an external sequencer. Also, you can load waveform data from Memory Card
and play it back as a drum voice.
Effects
Effects can be used to alter a sound, for example, to make it sound wider or distorted.
System Effects apply to entire drum kits and Insertion Effects apply to individual drum
voices. Reverb and chorus units are available for system effects and Insertion Effect units
offer a variety of effect types. Also provided is the Localizer, a 3D-type effect for headphones.
Songs
An assortment of 164 Preset Songs (P1-P31, Q1-Q67 and R1-R66) is available, consisting of
not just drum voices but also keyboard, bass and other accompaniment sounds. When
playing back these songs, you could mute just the song's drum voices and jam along by
playing the drum part yourself. One main song plus up to three Pad Songs can be played
back simultaneously. You can also record your own performances to User Songs (U1 to U32).
A song consists of two tracks, each holding up to 16 MIDI channels of data, and it's possible
to create songs in great detail using Step Recording and the functions in Song Job mode.
