In most cases you are using your Analog Four in Poly mode: Unison 2 will be sufficient. You can get that extra vintage sounding with more voices like I have done with the lowend101 patch 41 called PtchUnison
Unison is really one the main tools used to fatten-up your sound on the Analog Four at the cost of at least one voice. The result is the sound gets to a new level, it’s like you inject in it some density.
You probably see I use quite sometime the Unison-2, but what’s Unison ?
Doubling, stacking and Unison… comes from the same concept.
Warning! Unison or Doubling the same waveform can lead to partial or full phase cancellation, be aware of that. (especially with simple waveforms like sine wave and triangle)
Also when using unison on the low-end, sub, bass or whatever try to not spread to much the sound… try to stay in the middle (mono)
Doubling the same waveform result a boost in volume for sub on the Analog Four it’s a very good tool because when filtering the triangle you will loose volume of the sound. Generally it’s a good practice with doubling to set the waveforms by an octave apart, We can also use the analog four sub osc which is a square wave.
Another technique is 2 oscillators (or more) slightly detuned from each other and that will fatten-up the sound.
This technique is not far from Unison synth option.
If you use Unison you get that FAT sound but you still keep a lot of room to experiment with the Timbre because you keep 2 oscillators and theirs sub-oscillator to play with.
Unison
In fact you use voices instead of oscillators, you have the detune setting as well so you can drift more or less the resulting sound. I advise to not spread too much as you take the sound from mono to a more stereo sound and for sub well it’s not really the best. Keep things simple in terms of waveforms usage and in the center : get that energy and keep it Fat!
You can access to your Analog Four Unison settings in POLY CONFIG in the KIT menu or by pressing : [FUNC] + [MIX]
ALLOCATION mode : UNISON
UNISON Uses (x) voices to play the same note.
UNISON DETUNE sets the offset (0–127) by which the selected unison voices will be detuned.
UNISON PAN SPREAD set the width of the pan spread (0–127) around the center point of the unison sound. (see you make your sound from Mono to a more Stereo Sound super cool for a lot of sound, but for Low End Sounds be gentle on the spreading feature)
Note: I would like to pinpoint something here, every sound can not be loud – that’s not because your sound is not loud it’s weak. Every big sound needs a weaker or softer sound to reveal their Fat aspect. If everything is compressed to the max then you have sucked the life of the track. If everything is loud there’s nothing to notice anymore from a loudness perspective.
