Time varying factors are almost the entire point. You can easily add non-linear elements to any filter, it's been done since the earliest days of digital filters, making it sound right while you modulate it quickly is the tricky bit.nineofkings wrote:Only to an extent. The thing about EQ is that it's global, whereas synths generate sound per voice. You might EQ a perfectly creamy sound in octave 4, but play in octave 5 and it sounds boomy and terrible. Not to mention time-varying factors like dynamics, phase, and drift.fluffy_little_something wrote:I am more and more convinced that EQ is the key to the sound of a synth. After all, properties such as metallic, bright, dull, lacking bottom, and even fat and thin, or analog vs digital can be corrected/achieved by equalization to a large extent, be it an external EQ or maybe an EQ profile hardwired within the sound engine.
For that reason I wish synths had better internal EQ's, especially graphic equalizers with a dozen or so bands.
No EQ is going to fix that problem, period.
Don't get me wrong, per voice EQ is cool, that's what a "filter bank" is all about. It's just not an overall solution for the perceived differences between synths.
