My point was that, chorus and flanger can sound great when you want your synthesizer to really sound like a synthesizer. But I prefer to use other forms of modulation.
I think there are good points here when it comes to chorus/flange versus building it into the sound. One of them is what the LFO in a chorus/flange effect really are up as its essentially an approximation to multiple players being ever so slightly different in pitch and timing. One delay line and an LFO will add some movement to the sound but not be a multi-player substitute.
One additional reason I don't care for chorus or flanger as a substitute for LFO modulation is that each sounds unnaturally regulated. You can actually hear the rate of the effect, which screams, "electronic!" LFOs obviously are regulated as well, but when you use
multiple LFOs - as I described above - then the rate of each becomes immersed and lost in the complex modulation of the patch as a whole. The end result is that you don't especially notice the modulation...unless you turn it all off. I would say that's the right type and level of modulation for strings - that which goes unnoticed until it's removed, at which point the patch sounds unnaturally static and lifeless.
When I first bought a Prophet '08, I tried several choruses with it - an MXR, Fishman, and Electro-Harmonix. I liked the EH the best, but regardless, I just didn't like the finished sound. Plus, when I switched off the effect, I had a hard time adjusting to the stale sound of the instrument by itself; I wanted the chorus on all the time, as if the synthesizer was a Hammond organ that cried out for a Leslie rotating speaker. It struck me that using a chorus was not the right way to design sounds, but more of a cover for poorly made patches. Again, a stereo chorus can sound fabulous, if that's the sound you're after. But it can also keep you from finishing your patch, from striving to create the very best sound without the effect - one that is so good that it doesn't need the effect.
The end result of my eliminating all choruses was the forced exploration of the modulation potential
within the Prophet '08. Since then, I've never felt the need for a chorus or flanger.
