Tips on Feedback Modulation?

I saw this video shared by Elektron:

Description says:

Elektron Analog Four can generate sounds without using traditional oscillators or note sequencing. In this example, all the sounds are created only by internal feedback paths and resonating filters together with intricate lfo modulations. The amplifier section is triggered by a note-on and that is why the sequencer is running. Note, at 19:33 the sequencer is being stopped and the release phase of the amplifier envelope was still active while uploading this video. It may look like one of the external inputs are being used but it is not, only Out Left and Out Right are connected.

I became very interested in some particular sounds the a4 had created here, however I can’t seem to wrap my head around exactly what is being done here.

Can anyone point me in the right direction?

Also if anyone has attempted doing this, I’d love to hear your results!

I’ve seen this also a while ago and got pretty hooked on it! Let’s go and find out!

This is what you need. Sounds posted in the thread:

Osc 1 Feedback Analog Keys/Four

So the feedback input for Osc 1… Wow! I have been totally neglecting this parameter until last night. I have just opened myself a whole new can of worms. Squishy, distorted digitally controlled worms… Yum! This is now my new favorite feature of the A4. Couldn’t find much else about it either here or in the manual. All the manual says is that it is filter feedback. Sounds to me like it is feedback from Filter 1 (but not Filter 2) via Osc 2. In this example I have Osc 1 set to Feedback and Osc 2 …

That’s exactly it!! Can’t wait to get back home from work and try this out.

Thanks so much man :'D
