There are 4 patchers right after hipass filters. Each patcher contains 2 xfading allpass filters with different delay times since we can't modulate them (yet).
Reverbs creation
Thanks for pointing out that those allpasses hidden in the patchers in the middle of the FDN tank.
I wonder how much the sound will suffer if we just use static allpasses in the reverb tank, compensating for that by using a six-line FDN instead of a four-line FDN and by putting 10 static allpasses in series before the main FDN tank.
Time for me to get my own Axoloti and find out for myself.
this is sounding pretty lush! using it and comparing it to @kausto's effort - very different reverbs!
ill probably end up using the Schroeder for a lot more sounds, but the Keith Barr reverb lends some really interesting textures to standard house/techno sequences
i cant get either of these to open in the latest release :[
Thanks @kausto for your reverb patches, I'm really enjoying them, they sound very nice. Great work
I made more hi-fi version with improved modulation section. It consumes 42%CPU and almost whole SRAM

Little example (made with more early version which had improved sound engine but non-improved modulation section).
Synth1 VST is sequenced in Renoise being sent to Axoloti and then returns back into Renoise.

This one was made with latest version. I'm pretty impressed
Amazing! Sounds really great. Insert a pitch shifter in a feedback loop and you would be in Brian Eno heaven!
i rebuilt that keith barr reverb in pure data ... with a few added twists like rhythmic/chaotic modes. i used higher order primary numbers for the allpass filters and no time shifts so its more a cross between an echo chamber and a reverb.
here is a track with it, sound source is a tiny yamaha qy-10 sampler: http://tindeck.com/listen/fezoa

thanks! ... here is a schematic of it: http://drive.google.com/uc?id=0B1beo8lTIeKlclhIOW9QN1lKMXM
as you can see its just 6 allpass filters in a loop and you can send it a list of numbers for the delay times. in this example i used primary numbers around 100 ms. you could modulate these and get totally different results.
this should be easy to do on the axo. eventually i want the reverb to be integrated into a sequencer patch, then you could sequence a midi synth and run the audio through the axoloti like in this track. this is all done in pure data again: http://tindeck.com/listen/ipmiq
Nice! I can see where the 'time list' inlet is key. Do you have some kind of list generator behind it? Or do you just cut those by hand?
Made this 8 allpass + 4 delay loop reverb in style of Keith Barr which utilizes @SirSickSik's Pitchshifter2 in feedback path

It also utilizes allpass m hq by @Jan
Thank you guys!
Proper allpass with modulatable delay is still needed though
oh, I made this biquad filter last week... also features an allpass mode, though not stable at very low frequencies I guess.. (wasn't stable there in synthedit either) not sure if I uploaded it.. think not as there were still some problems with some filter modes
