Lets have some feedback

Postby Benzebub » Sun Jul 13, 2014 6:56 pm

Hi all!

Let's discuss feedback.
How do you use it? Do you find it useful?

When I first got the Mopho X4 more than a year ago I first found it tricky to use use it without it being either overly distorted or not having an effect at all.
I discovered that adding resonance to the filter to cut out some low end really made it possible to turn it up without the sound completely distorting and I could get some really thick bass sounds this way. Also, I find it useful for pads when modulating the amount subtly.
What do you guys think about it? Anyone loving this feature?

I like having feedback in the arsenal, but I don't use it extremely often. My favorite use of feedback is definitely feedback-in-motion, where it's controlled by the sequencer or with a sample-and-hold LFO to create rhythmic sounds.

I kind of prefer the Arturia's SomethingBrute implementation of feedback ("Brute Factor"), which feeds the signal directly back into the filter input.

Old topic but got to thinking about this and have been playing around with it again.
I have played around with the feedback feature on the Pro 2 and must say it is not as great as on the Mopho.
I did not see a point in the 2-pole filter on the Mopho at first. The resonance just killed the bass. Sure, it is great for PWM strings in that it makes them a bit ethereal but for other sound I found it to be weirdly designed. Until I tried it with feedback. As I mentioned in the OP it makes for good bass sounds and this really makes the 2-pole shine.

Well... I never really used feedback when I had both Mopho and Tetra, and my P08 does not have that feature... I've not used it on P12 either... so I cannot really participate in the debate.... but... I've been trying to use it quite a bit on the Tempest, simply because I hate the fact that the analog distortion on Tempest is global, and not per voice.

So I've tried to use feedback for a distortion like sound on a voice basis, and learned a few truths about that kind of feedback. First, if it's used on a self oscillating filter only (for kick drums especialy), it sounds like s***... a total mud-ferno... not even worth using in the slightest.... but used on oscillators it sounds really good and distorted... only bummer is that the oscillators on Tempest is rather inconsistent in the transients, so that sort of like erase that use of the feedback parameter (in addition to a few other Tempest feedback truths).

On synth sounds, I've only used it a couple of times, on Poly Evolver... for making plucked physical modelling style sounds with the tuned feedback... takes some tweaking, but it's definitely doable.

Regarding Mopho specificaly, I do NOT like the fact, that the feedback parameter is not a parameter in a preset... I like the Tetra better in that respect... I hate it when synths do not support preset storage of ALL sound parameters, and it's usualy a deal breaker for me... just like with Waldorf Rocket... Resonance is not storable, so no Rocket for me :lol:
