Drum Kit Overview
What's a Drum Kit?
A drum kit is a collection of drumsamples (drum set
sounds such as bass drum, snare, or cymbals, as well as
a wide variety of other percussion sounds), with each
sample assigned to a note of the keyboard.
• Each key can play a different sound
• On each key, you can use up to eight Drumsamples,
with velocity crossfades
• Each key has separate settings for the most
important sound parameters, including volume,
filter cutoff and resonance, envelope attack and
decay, pitch, drive and low boost, and gain for each
band of the Program EQ.
For instance, you could combine high drive and
low cutoff frequency to create a lo‐fi effect on only a
few sounds, while the rest of the sounds remained
clear and pristine.
• Each note can be routed to different Insert Effects,
or have separate FX Send amounts. For instance,
you can send a snare sound through a dedicated
You can use Drum Kits only in Programs whose
Oscillator Mode is set to Single or Double Drums.
Drum Kit memory structure
The KROME has over 161 Drum Kits, divided into
Internal, User, and GM (General MIDI) groups as
shown below. You can edit or write into any of the
locations except for the GM bank, which cannot be

The 9 Drum Kits in the GM bank are compatible with
the GM2 sound map. The other Drum Kits may use
different mappings, where appropriate.
Using a drum kit in a program
In the Program P1: Basic Ctrls– Program Basic page, set
the Oscillator Mode parameter to Drums or Double
Drums. Then for the oscillator, select the drum kit that
you want to use.

Before you start editing...
Selecting a drum program
Drum Kits are edited in Global Mode. While you're in
Global Mode, you'll play the kit that you're editing as if
you were playing it from within the Program, Combi,
or Song which was selected before you entered Global
So, before you enter Global mode, it's best to select a
Program which is already set up for drums, with the
appropriate EG settings, effects, and so on. Just use the
Program Category select popup, and choose a drum
Program such as "Studio Standard Kit."
Even if the program's oscillator is set to Double
Drums, this page will show only the single drum
kit that is selected by Drum Kit Select.
Matching the key of the keyboard
with the drum kit
In order for the note mappings to match the keyboard,
the Oscillator's Octave setting needs to be +0 [8ʹ]. All
Drum Kit Programs should have this setting already. If
you're unsure, you can check this yourself:
1. Go to the OSC1 Setup tab of the OSC/Pitch page.
With a setting other than +0 [8ʹ], the relationship
between the keys and the Drum Kit sound map will be
2. Set the Global P0: Basic Setup– Basic parameter
"Key Transpose" to +00.
Make sure that Memory Protect is
Before you start editing, go to the Global P0: Basic
Setup– System Preferences page, and look in the
Memory Protect section. Make sure that Drum Kit is
not checked–if so, you won't be able to make any edits.
Drum Kits may be used by more than
When you edit a Drum Kit, all Programs that use that
Drum Kit will be affected. To avoid changing the
factory voicing, you may wish to copy Drum Kits to
empty locations in the USER banks before editing.
