2.12 a nice thick oscillator method:
Colin called this PWM; I would disagree with this, it sounds a bit different. But it’ s a nice
chorus-y type effect.
Colin writes:
Put a NegativeSaw on one oscillator and a PositiveSaw on the other. The more detune between the
oscillators the faster the PWM. Interesting effect sound more like the PWM on a Juno - thinner and
smoother than the standard PWM :)
2.13 a trick to get lower frequencies in an oscillator:
Mike Peake writes:
Also, there is a trick available when you use Osc1 as an FM source. Select Preset 2, Program 127
"Zweeper Ribbon". (If that's it's location off the top of my head.) Note that Osc1 is used to modulate
Filter 2, which is in self-oscillation. Oscillator 1's frequency has been significantly lowered by
modulating it's frequency with it's own output using a Mod. I believe offhand that it's Oscillator 1 Mod
2 doing this. You select the Ext->Osc Frequency Mod Destination and use the Offset to bring up the
amount. Go to the Oscillator NZ/EXT page using the appropriate soft button to select Oscillator 1 as
the Source. Oscillator 1 can be moved to extremely low frequencies using this method, and can of
course be used to modulate Oscillator 2 and either Filter's frequency.
2.14 square level note – setting the same as the sawtooth
From Colin:
Currently when you turn on a square wave its volume is at 50 which is currently too loud! If you then
hit the up/down arrows it moves the volume of the square wave to 22 which makes it the same as
the sawtooth - much better
2.15 sub oscillator mixing note:
From Mike Peake:
on the sub-oscillators the sub osc knob seems like it is for mixing the sub osc, not just for level as
the manual suggests... is this correct? Alll the way left is no sub osc, middle is equal parts sub
and primary, all the way left is all sub osc...
Level is mixing... All the way right will allow the suboscillator to overwhelm the oscillator it's derived
from.
2.16 sub oscillator level note:
From Colin and Mike Peake:
They keep their level with respect to the main VCO regardless of the level of the main VCO on the
Pre-Filter mixer. Just thought I'd mention that, the manual may have mentioned that - I dunno I
haven't read that section :)
Colin
I believe that's in the Using_A6 document... The reason is so that they're summed into the total
oscillator output, which allows them to be used for FM as on the CAT monosynth etc. Since the
oscillators also have a lower frequency limit of about 18Hz, for deep, deep sub-basses turn off the
oscillator waves and turn up the suboctaves and you'll be able to track that last octave.
2.17 phase cancellation:
(sound going in and out or clicking at certain points)
Unlike digital synths which allow you to have less phase cancellation, the Andromeda
allows you to create patches that phase-cancel each other out at certain points, producing
annoying beating sounds. If you are not used to this (e.g. you have not worked with a real
analog before), you will have to get used to adjusting the Andromeda by ear.
