WAVE

is a mix control that continuously sweeps the oscillator waveform from sine-wave 
to square-wave. Here, the sound changes from soft to edgier. At higher values, the 
sound will start to get increasingly overdriven and distorted. The interaction bet-
ween 

WAVE

 and the 

FM

 parameters will produce a wide range of timbres for various 

types of percussion sounds.

MULTI

Figure 5: MULTI instrument channel of the DRM1 MKIV

MULTI contains three oscillators, each sporting a wide tuning range. This makes for an amazing 
variety  and  scope  of  tones,  ranging  from  bass  drums  and  toms,  to  cowbells  and  other  metallic-
sounding percussion, to far-out sound effects.

DECAY

determines the duration of the sound.

PITCH

sets the fundamental pitch frequencies of all three oscillators.

BEND

adjusts the modulation amount of the 

DECAY

 envelope, controlling pitch. When at 

center position, no modulation will be audible. From the center position, turn clock-
wise to modulate pitch downwards. Turning the control counterclockwise from the 
center position will invert modulation, resulting in ascending pitch. 

ATTACK

adds a short fixed-level transient spike to the initial attack phase of a sound to make 
it extra punchy. Always adjust 

ATTACK

 in correlation with the complete mix.

PITCH 2

sets the pitch/frequency of the second oscillator. Changing 

PITCH

 will always chan-

ge the frequency of 

PITCH 2

, too. 

PITCH 2

 can be independently adjusted to make 

it sound lower than the first oscillator. Turning 

PITCH 2

 fully counterclockwise will 

shut off the second oscillator completely.

PITCH 3

sets  the  pitch/frequency  of  the  third  oscillator.  It  works  the  same  way  as  the  

PITCH 2

 control works with the second oscillator.

HIGHPASS

adjusts the cutoff frequency of an additional high-pass filter. It allows attenuating 
bass frequencies of the sound if so required. The effect the filter has depends on the 
pitch of the sound. When 

PITCH 2/3

 are set beyond the 9 o’ clock position, the effect 

of the high-pass filter will hardly be noticeable.
