A beginner's guide to the components of a modular synthesizer

5 - THE VCLFO (Voltage Control Low Frequency Oscillator) :

The VCLFO is an LFO that we can control using an external voltage.

As you might expect, it’s an oscillator which oscillates at very low pitch (usually so low that our brains no longer perceive it as a tone.)

RATE pot (frequency) : this potentiometer adjusts the speed of the LFO.

CV IN (for Rate) : is a CV input to be able to modify the speed (Rate) with an external voltage (another LFO for example)

ATTENUATOR for CV (Rate) : allows you to manage the signal entering the CV (CV in for Rate).

SAMPLE AND HOLD pot : generates random pulses

WAVE DISTORTION pot : allows to distort the outgoing waveform

SYNC ON/OFF switch : to select external or internal synchonisation.

LEVEL pot : to control the level of the LFO out

WAVE FORM BANK switch : to select Bank 1 or Bank 2 for differents wave forms

OUT : 2 output of the module + 2 others inverted out

CV IN for Level : to manage the LEVEL pot with an external signal

ATTENUATOR for CV (Level) : to adjust the level of the CV incoming

WAVE FORM pot : potentiometer to choose in a differents selection of wave form (square, triangle …)

SYNCHONISATION INPUT : to control the rate of the LFO with an external clock signal

MULTIPLICATION RANGE pot : to multiply the LFO rate

Example of a simple patch with this 5 modules (VCO + VCF + VCA + ADSR + LFO)

OUT of the VCO to INPUT of the VCF, OUT of the VCF to INPUT of the VCA, OUT of the VCA to your system

OUT 1 of the LFO to trigg the ADSR, OUT of the ADSR to CV IN of the VCA, OUT 2 of the LFO in CV IN of the VCF, maybe try INVERTED OUT of the LFO in the CV IN of VCO …

now there are starting to be multiple possibilities :slight_smile:
