Drum Synth
The Drum synth module is designed to generate classic analog drum sounds. It consists of a master and a slave oscillator in combination with a noise source and a multimode noise filter. The global parameters include a bend function and a click and noise mixer. (See
"Voice definition" on page 210 for an example on how to build a multi drum synth patch using only one single voice in Nord Modular.)Trig
The yellow Trig input trigs the Drum synth module each time it receives a signal that changes from 0 units or below to anything above 0 units. This signal could come from a gate output of a Keyboard or Sequencer module, for example. A green LED indicates when a trig signal is received.
Vel modulation input
This blue control input is used to receive velocity information from an external source. The input velocity signal will affect Master and Slave Oscillator Level, Noise Filter Sweep, Bend Amount, Click Level and Noise Level. Maximum input velocity will force the parameters to reach their current settings.
This blue control input is used to receive pitch data from an external module such as a Keyboard or Sequencer module, for example.
master and slave display boxes
The Master display box shows the master pitch in Hz, and the Slave display box the pitch ratio related to the master pitch. Range: Master: 20.0 Hz to 784 Hz. Slave: 1:1 to 6.26.
Master and Slave knobs
These are the parameters of the two oscillators that generate the basic drum waveform.
Tune:
The tune of the Master can be set between 20.0 and 784 Hz. The Slave ranges from 1 to 6.26 times the Master frequency.
Dcy:
Decay determines the decay time for each oscillator. Range: 0.5 ms to 45 s.
Lvl:
With the Level knobs you set the respective volume of the two oscillators.
Noise Filter
Here you can filter and affect the noise component of the Drum synth module.
Freq:
With the Freq knob you set the cutoff frequency of the noise. Range: 10 Hz to 15.8 kHz.
Res:
With the Res knob you set the resonance amount around the cutoff frequency.
Swp:
With the Sweep knob you set a sweep range for the cutoff frequency. The setting results in a sweep from a high cutoff frequency down to the frequency you set with the Freq knob. Range: 0 to 5 octaves.
Dcy:
The Decay knob sets the noise sweep and decay time. Range: 0.5 ms to 45 s.
HP/BP/LP:
Click on the HP, BP or LP button to select filter mode: highpass, bandpass or lowpass.
Bend
Bend is a global function for the Master and Slave oscillators.
Amt:
With the Amt knob you set the bend amount, i.e. the frequency range to bend through. The bending always start from the higher frequency and sweeps down in frequency. Range: 0 to 5 octaves.
Dcy:
With the Dcy knob you set the bend decay time. The bend time can be considered more as a bend rate, since the actual decay time is determined by the Decay knobs of the two oscillators. Range: 0.5 to 45 s.
Click
With the Click knob you can add a clicking sound to the attack of the sound.
Noise
With the Noise knob you set the noise level in the total mix.
Preset
Here you can choose between a number of factory presets by clicking on the up or down buttons. The preset name is shown in the display box.
M
Click on this button to mute the audio output of the Drum synth module.
