…ahhhh, what a beauty…love it…
Thanks for the ‘feedback’ guys 
@Trabant OSC1 is set to feedback, OSC2 to a Pulse with Sub set to 5th and some slow but deep positive PWM. Sync set to metal and fully engaged.
Then it’s just a matter of playing some notes with different velocities and letting the slow random LFOs screw the filter. Lots of reverb and a little chorus and off you go!

B I G phat thanks!!! finally it sounds like I am part of the kool kids!
I’ve found lately that the Feedback OSC makes great intros and outros for live sets.

Wow I just read about this Feedback feature today so I put together this here track - EAR BASHING NOISES!
sweet
Here’s a soundscape style thing (something to do with Iran was on my mind) - using some the patches uploaded in this thread - cheers Cocker & co - lots of infra-sound so go low!

I just try it. Nice !
Thank to those who point me in that direction.

pssst !
Great to see this thread still inspiring new stuff after so long.
The A4 truly is a remarkable synth
And the Feedback Osc is the shit !!

It is! This thread was an eye opener back then
I spent my whole evening yesterday playing with it, so nice.
However I have still not understood exactly how it works…
Would someone take the time to explain ?
I think of it a little bit like No Input Mixing
If you haven’t looked that up before than give it a google
Feel free anybody to correct me if I’m wrong but…
Basically, in Feedback mode the Oscillator does not need to cycle a waveform to generate audio
It passes it’s output back to it’s input recursively
Any tiny amount of noise in the path can be amplified by feeding back on itself
It’s a pretty unstable way of generating tone but it works well for really raw edgy stuff
I like that Elektron have included it. It’s fairly unique. You don’t find it on a lot of synths
DSI now make a Eurorack Feedback module and I believe it’s a feature on some of the newer prophet synths ?? Not sure how well they’ve implemented it in the signal path of the rest of the synth
Elektrons one is very well done in that it can be modulated by OSC2 and the LFOs/ENVs

In esence it uses the osc1 volume control to mix in the output of the filter section: very much like the famous "headphone to external input-trick"on a minimoog. Result is a feedback loop that includes the filters.

Yes this. The filter drives it mad.
I used it here in the bass sound. Actually I use it a lot. Gives the A4 it’s own life somehow

I’ve been playing around with that on an MS-20 recently; now I need to combine it with the feedback on the A4, and to get some cross-modulation going.

I had, at the time this thread was created, and couldn’t make sense out of it.
Maybe I should try again now indeed 
Thx folks !

Yes. Just be careful with your speakers… and ears. It can get very loud quite quickly
