ORGAN TONES

Start with a supersaw set the three pitches to taste automate filter sweeps with lfo

a very common thing to get organs in analog synths is to use a sub oscillator TWO octaves below the main oscillator....then choose a square wave for the main oscillator; you can get such oscillator arranges by using the superwqve square or ensemble

In ensemble you can also get some intermediate harmonics by setting notes to specific intervals...set the wave parameter to achieve an square wave

Set a lowpass filter static in a low to mid frequency and turn up resonance.

With classic ADSR you could use the amp EG to simulate the click at the start, but no luck whit the odd EG on the mono...still you can use an LFO with max modulation aplied to volume to get a spaike at the start of the sound...just put the LFO in one-shot mode, choose a linear or logarythmic falling curve and set the speed as fas as you can.

Another way is to set the filter EG to minimum time attacjk and decay, and turn up a little the EG depth of the filter. The amp has to be controlled by a kind of gate EG, so choose minimum attack and release and set decay to max to get infinite sustain.

3192725283_706f736860_m.jpgUse the other LFO to achieve Leslie-style FX by modulate pan and pitch in a doppler way.

If you’re in the ensemble oscillator you can fat your organ using the chorus in the synth section.

Put some reverb with long decay but in very little quaqntity, so you can only hear the tail when you leave the keys

In Ensemble Wave where you have 3 pitch parameters which you can setup in relation to the note triggered, e.g if you trigger G3 and set the first parameter to +2, the second to +3 and the fourth to +7, then you’re triggering a Gmin9 chord. Now use locks on the fourth parameter going to +5 or +8 (meaning youl’ll go from D to C and then to Eb).

Organ sounds are like chords in itself...with strong frequency components that could match note frequencies, even in a single played note, so you could use the ensemble “notes” to get something similar. Sometimes these notes could be too loud to get just formants but try it anyway; with a bit of lowpass filtering you could soft the higher ones leaveing the fundamental dominate the timbre

FM is another way of get organ sounds because of the ability of this synthsis method to get several harmonics from just 2 oscillators...try exact multiples of modullator/carrrier frequencies relationship to get those harmonic regions in the organ, after that you could shape some things with the EQ to get some region low or high

TIP: Distortion on the MnM is very crude and digital so maybe it not suited for dub organs, you´ll go better with an external analog devise, a tube one ore a modelling thing like the some of the POD models.

Organ patch:

IMPORTANT : FIRST turn OFF the keyboard tracking of both filters.

KIT > ASSIGN > KEY > HPF and LPF has to be in OFF.

then set as follows:

SYNTH > SUPERWAVE ENSEMBLE MACHINE

PITCH 1 = -12 PITCH 2 = 2/3 PITCH 3 = 12 WAVE = 127 (SQUARE) PW = 29 CHRL = 9 CHRW = 127 TUNE = 0


AMP

A = 0 H = 0 D = 127 R = 0 DIST = -9 VOL = 90 PAN = 0 PORT = 0


FILTER

BASE = 2 WIDTH = 79 HPQ = 84 LPQ = 31 A = 0 D = 0 BOFS = -6 HOFS = 16


FX

EQF = 79 EQG = 11 SRR = 0 DTIM = 2 DSND = -19 DFB = 56 DBSS = 22 DWID = 81


LFO 1

PAGE = PITCH DEST = 1/12 TRIG = FREE WAVE = TRI MULT = 32x SPEED = 64 INTL = 0 DEPTH = 33


LFO 2

PAGE = AMP DEST = VOL TRIG = FREE WAVE = TRI MULT = 32x SPEED = 50 INTL = 0 DEPTH = 12


LFO 3

PAGE = AMP DEST = PAN TRIG = FREE WAVE = TRI MULT = 16x SPEED = 64 INTL = 0 DEPTH = 55

Go to octave 6...play step keys 9, 13 and 16 rhythmically, then hold that interval move the whole chord 2 semitones and you´ll be transported to bossa territory instantly.

If the sounds too dissonant in some chords you can change the interval of the osc pitch 3 try change the wave, PW, filter width and EQ freq parameters to get another tonalities

Take it as a starting point...it sounds like an organ but of course you can let the mono goes far from it...

In the OSC you can see the different notes who conjure some of the timbric personality of an organ, the other things that helps accentuate it are the resonace peaks of both LPF and HPF; they serve as a FIXED harmonic shaper since the filters doesn´t track the keyboard and makes the organ some of the character of a speaker cabinet.

One thing I really like is the spring reverb-like delay...see the short delay time plus a long and filtered feedback

The LFO 1 makes vibrato and the LFO 2 makes tremolo...they both helps to get some of the cheese tones of say, a farfisa organ or something like that. LFO 3 makes auto pan to get some stereo movement like leslie FX (not an exact reproduction but workable)
