Meaning that you could in practice use six 303's in Caustic.
As Caustic is a mini Daw and not a groove box like the other applications it is not layed out to play in groovebox fashion, which is a disadvantage if you want to use it live,
it is possible but less friendly in this aspect,
but the advantage that it has is that you can record your automation over and over again
til you get what you want.
You will also sequence the 303 in a piano roll type of sequencer which is really nice as you can lay out a groove and then just move the notes around as you want which is not possible with the other applications so in this aspect it is easier to jam with.
The other difference that it has to the other emulations is that it has modulation built in to control either pulse width/Cut off or resonance.
Then directly there on the engine itself it has four different types of distortion.
With pre/amount and post controls.
One last thing that none of the other 303 apps have is a pulse width control...
Okay so far so good.
But there is always a but, soundwise it is lacking some omph in the bass
you can still get it to fill up the low end frequencies though.
Also feel it is a lack of clarity in the resonance as well-
you can kind of make up for it with some effects (equalizer like some other effects in Caustic can be up to two insert effects per sound engine plus delay and reverb like send effect), still dont make up for it totally and feel that maybe of the ones tried so far and without having done a side by side comparison that maybe Audiotool Sketch has the advantage soundwise and number two RD3 HD.
We will see tomorrow...
