I thought the microKORG was okay sounding and quite fun even to program, but it was hard to find the right sonic spot in my productions for it; it competed with major league players, like the analog Minitaur and the Juno-106, or some great softsynths like the Thor. So I sold it (and by selling it, I made room for another purchase).

Still, just because there wasn’t any obvious place for the microKORG in my personal setup, it doesn’t mean it’s a bad or redundant synth for everbody.

Anyway, before I sold it, I printed down two generic bass sound designs, very basic but still good sounding.

The FM Bass

The first sound is a FM-esque bass, though it doesn’t try to mimic the style of the classic Yamaha DX7 of the 80s (for that, choose sine waves for both oscillators, carrier and modulator, and bypass the filter section entirely).

You can use a LFO as the modulation source for the oscillator, but in this case I’m using another oscillator to achieve a fairly complex overtone structure with only two operators. So by definition, the bass is actually a Cross Modulation (X-Mod) bass type. Let’s start by breaking down the oscillators:

Osc 1: SIN, 25, 0, -, –
Osc 2: SQU, OFF, 24, 0, –

The first oscillator (carrier) is set as a fundamental sine wave with no overtones. Some depth of cross modulation is added (in the patch below, adjust this with the modulation wheel).

A square wave is used for the second oscillator (modulator), with the oscillator modulation turned off, and detuned two octaves upward for harmonic-component effects. Also, try tweaking the tuning for different sounds.

Here’s the full program (another timbre was layered to fatten the sound up a bit):

The Juno Bass

The other bass is merely a sawtooth, yet beefy, virtually analogish with emulated drift and such. It’s straight forward, yet powerful, and I think it showcases the strengths of the microKORG’s MS2000 sound engine.

There’s a number of ways to enhance this sound. For example, you can turn up the second oscillator, detune it a bit, add some chorus, and get a lead-like sound. Or you can modulate the cutoff slightly with a LFO to make subtle movements in the sound.

Anyway, here’s the program of the punchy single sawtooth bass:
