Playing around with a long delay

PDS-ish, with extras. looking like it'll have around 12-14 knobs when finished

That third video is very nice... Any more details about what's going on ?
Also, the second one sounds like artifacts from a longer delay time than what the memory actually allows, is that what's happening ?

The delay has 4 delay time ranges. 50ish milliseconds to quarter of a second, quarter to almost a second, almost a second to over 3, over 3 to 14ish seconds. the third video is me playing on that 14ish second delay with a lot of feedback/overdub. some modulation too.
the second video is sort of that. it "attempts" to stretch the delay loop longer
without changing the pitch (which is actually really hard to do, technically), so it's glitchy as hell

Cool. I (very simply) modded a delay to have longer times than what the chip is designed for and I can get some really nice crunchy drony sounds from that when the feedback is high enough, your second video sounded similar but somehow nicer

.
What I still haven't seen in delay pedals and that could be interesting in my opinion is discrete changes of delay time (i.e. going from one value to another in one frame). This can lead to really cool results especially when the various delay times are related to each other...
Anyway, very nice sounding prototype

its a lot of fun modding delays to be longer, to get those crunchy soudns as you say! 80s and 90s delays are easier for that.
I thought of doing that delay time change in an earlier pedal some years ago. a couple challenges prevented me from fully doing that, since there needs to be a way to blend the hard "edges" of past shorter delays, now audible.

Please take my antinautilus money so I can start saving up for this.

I'm just building this for myself at the moment, because I need one

Yeah, the one that I modded is from the 90's, it actually uses a karaoke chip I think, with limited memory. Modern digital delays are indeed something else (you could always code that part but where's the fun in that

)

Not sure if that's what you're talking about too, but I was thinking of basically having a buffer whose length would be the maximum delay time. And then only using part of it when you reduce the delay time (but keeping the data in the rest of the buffer intact). You can get some existing delays to sort of behave like that but with limited control.
Hmmm, I should get some sort of programmable pedal and write some code to do just that. But I would want one that accepts at least triggers from my modular, not sure if such a thing exists...

the videos don't show this thing, which I built to help prototype this. it's the core of the delay. all the breadboard is is the analog stuff and some support circuitry

Seriously, demos sound great. PDS was the shit back in the day.

Oh, that's nice... How much memory is there in this ?
I checked the Owl pedal (they're apparenyly preparing an euro module of it too) but it only has 1MB of memory.
That's not that much (6 seconds of stereo 16/44k) to do anything really interesting with audio buffers...
