An oscillator can produce a frequency that is too low to be perceived as a pitch. In this case it is known as an LFO or low frequency oscillator. Because the oscillator in your kit can be both low frequency or audio range, you can turn up the frequency of one oscillator and feed it into another oscillator to create “frequency modulation”.

John Keston explores the Bass Station II, below his report:
I have recently been trying out a Novation Bass Station II monophonic analogue synthesizer. I am quite impressed with this big sounding synth in a small package. While digitally controlled, Novation have focused on packing in proper synthesis features rather than trying to gloss over the sound with onboard effects. For example, as I have illustrated in the video, the filter self oscillates nicely with a clean sine wave that can be modulated in unique ways especially with distinct features like oscillator slew.
The video starts with the self oscillating filter getting modulated by LFO 2 using the triangle wave. After that I switch to using the sample and hold setting creating the well-known 60s computer sound of random notes. Here’s where it gets interesting though. Once I switch the LFO to sample and hold I start turning up the oscillator slew I mentioned earlier. What this does is variably smooth the wave shapes created by the LFO. You’ll hear this come in at 0:28. It sounds like portamento. At 0:35 I switch the LFO to the square wave, but with the slew on it sounds more like a sine. As I reduce the amount of slew the square wave regains its recognizable character. Next I switch it to the saw tooth wave. The nice thing here is that the LFO amount can go into negative values allowing the saw to be reversed.
Another distinctive feature is the oscillator filter mod setting. This modulates the filter with oscillator 2. Since the oscillators range from subsonic to almost supersonic this feature offers modulation effects that are not possible with the LFOs. At 1:29 you will start to hear the oscillator filter mod come in using a pulse waveform. What makes this interesting is that while oscillator 2 is modulating the filter it can also have the pulse width modulated by LFO 1. This can cause bit-reduction-like effects that can be heard between 1:49 and 2:19. At 2:20 I start tapping the octave and waveform buttons on oscillator 2 illustrating what happens when the modulation source is instantly shifted an octave at a time. After a bit more messing around I added a final, manual filter sweep at 3:20.
This is the second video aimed to demonstrate the diverse capabilities of the three oscillator desktop sized MacBeth X-Series Micromac-D analogue synthesizer. In this video, we get to hear what the Oscillator section does, plus a few extras! As always, when things get going- hows does one adequately show what the potential of this thing has? Watch on………..there’s some Trio-phony too!
ArcWave is a granular re-synthesiser for Native Instruments Reaktor that uses samples in place of oscillators allowing very diverse waveform generation from virtually any conceivable sound source.
The Demo Track “UnderWater ArcLight” was improvised live using ArcWave, no other synths, effects or sounds have been used.
The track was recorded in Logic on a MacBook Pro and uses only 9 patches.
Each part was independently bounced down before playing the next, leaving 9 recorded audio tracks at the mixing stage, two of the tracks had a small amount of EQ cut at about 500 Hz to remove some of the energy, plus a bit of automation was then used to control the track levels.
The finished mix was then bounced through a 5 band compressor in Logic to produce the 24bit master, no post processing has been added.

To give you a flavour of the 5 Oscillator/ 2 filter sound- MacBeth set up this on the M5X prototype. It’s pretty massive with hints of spring line reverb and cross modulation from one of the VC Modulators modulating as well as being audio! It’s a booming, massive sound!
In this video, Rich Formidoni takes you through the various types of oscillators that are the basic foundation of KingKORG’s sound.

This first A4 tutorial focuses on the Oscillator pages, and how to apply dynamic changes to a static sequence by modulating parameters with the velocity.
