No More Delays On Delays!

Tomorrow hopefully the #2399 Triple splashback will be available. attached is the schematic for it. and also a simplified schematic which im currently plotting out for a strip board layout which I hopefully will be able to successfully test before the video on it all which will be up on Friday! .... if all goes well.

as you can see from the schematic, if you look at the pt2399 data sheet, you'll see thats where I began on this project as this module is to replace a dual pt2399 strip board layout I made to the data sheet a few years ago, and used it in my synth and liked the way it sounded and fedback. 

So as you have seen from the vlogs, I started about a month ago on this oner breadboarding initially just the datasheet then just kept adjusting things changing aspects to it etc, for instance you'll see I have bypassed the second filter and stuff. after a week of mulling on it spending a couple of hours just putting components into the breadboard and pulling components out I settled on something similar to the above. right up to the last moment I have been switching values here and there! so needless to say most can be swapped for near enough values. 

I was going to at the beginning do something funky with the vco of the pt2399 and mess around with it to make a rudimentary sync and try other things maybe even get a downsampled delay out of it, however I have held off as the purpose of this module was to be a drop in replacement for my dual delay,

however when you see on Friday, or in my other videos involving it, it has become quite a lot more than that already! it has a lot of scope to be anything from a tight echo near chorus to a reverb to a stand alone laser battle machine. two of them together is pretty damn fun I found myself today plugging two together with a volume adjust in-between yeah truly weird.

I have built a lot of pt2399 devices in the past but I usually stayed rather safe, but this one I don't know how but managed to make it do things I haven't heard the pt2399 chip do before. 

i'll explain more on Friday. 

The schematics can get very confusing when there are more than 1 board involved, but in short there is 3 delays in series, a master time adjust with 2 sub adjusters to offset the 3 delays from each other. then topologically the fastest one runs into the slower ones. 

I already have plans for a bigger one. im working on it as one of the macro modules. I mean huge! in-between 10 and 16 pt2399's. attenuverters for the offsets and different routing it'll be a truly awful machine.
