Sound of Shadows Expansion Module

As far as the expansion goes, I say really take your time. The additions should take full advantage on any exploitable quirks in the circuit to turn an already very cool delay into something truly otherworldly. I love the idea of bends or happy mistake crossed wires that do something this thing was never meant to do. I had some great stuff going with the Choices controlling delay time and frequency of a Polivoks in the feedback look and a Pressure Points running feedback. Good shit.

SoS is amazing with any input signals be them lfo slow or audio rate. it does crazy shit in audio territory but it works wonders. i also just figured out how to make it flange REALLY nice (inspired by Kent of course). as always, attenuators are our friends in regards to the incoming modulation of the SoS. definitely jacks for cv and attenuation for them!

i am still jazzed about the SoS!

Flight,

If you are already considering a VC-Mix control then that takes care of items # 1 & 2 on my list. I wasn't sure if it was possible, given the block diagram, so I was giving an overly long explanation of a kludge that could work.

If there were some way to have a Wet/Dry control on the Insert point, that would be swell.

Also just checked that out. An ATTENUATED audio rate signal in to rate does some nice almost ring-mod like effects on the delay. Too much signal and it goes into very nasty and loud noise.

Ã¢â‚¬Â¢Any circuit bends on the PT chip? Perhaps some momentary push-buttons or SPST (or other) switches if fun is to be had here.

Good idea. There are a few bend points on there that I found. I made a test rig that brings all the connections out for easier testing and I often end up playing with the exposed traces.

This definitely has my interest! Some "sound of thunder" type of circuit bending switches on the expansion would be rad... what kind of bends have you found so far Flight?

i agree. some circuit bends would be cool, even if they just do something simple like change the color of the the sound.

I will (take my time), don't worry. I'm actually thinking of doing two expansions: the first will just have the Rate LED and attenuated CV inputs, and be about 6-8hp. Now that it looks like there will be enough for it, the other will have the "exotic" functions and probably be 8-10hp.

*Phew* OK, cool.

Probably not - the Insert is hard-wired - but what other signal would you mix in there? Any combination I can think of is really the job of a mixer. I'm trying to avoid duplicating common existing modules.

Mostly just rate and feedback weirdness so far. I haven't actually tried finding any, just happenstance.

Here's that audio rate CV. Damn I'm having fun with this one!

This would be so that the inserted effect could be faded into the insert point. Imagine if you could fade in a Moog MuRF or a Phaser onto the delay repeats. That's what I'm getting at.

First, gotta say, I love the new name. It fits! I do love to lurk.

Could you describe that signal-chain-wise? I'm having a hard time with it. My guess:
Signal into input --> Delay out to effect --> effect output to Insert.
So are you saying you want to crossfade from the "plain" delay out signal to the "effected" delay signal?

I should probably make a clearer block diagram before we continue... the existing one is very vague for this kind of thing - we need a schematic.

Can I pre-order one of each?

Sure! As soon as I have an idea on cost.

And the "flowmatic" (attachment):

could one of the expansion modules have the word "turbo" in the name? i just really like the word turbo.

OK...back on task...haha.

Clever people, please let us know what mystical incantations can be derived from Flights "flowmatic". I know little of these matters.

*boing boing*.

This idea needs a bit of explanation:

The other day Exuviae brought over his SoS and wanted to compare his to mine. With the same source material going to both and with the knobs set the same, we both cranked down our Rate knobs to see how "pukey" it could get.

Mine would get ugly (in a good way, mind you) around 8 o'clock, and if the rate was increased, it'd stutter back to life in a glorious way.

His would never get that dirty. The delay times would increase, sure - but the material wouldn't get ugly (or pukey, really).

We might have a recording of this (maybe, Audacity took a dump on me) but this brings up a question - is there any way to 'tailor' the response of the Rate knob? I glanced at the PCB when moving things around in my rack, and I didn't see any trim pots to adjust.

Any idea regarding the different responses, 'Flight? Maybe this is something that could be an end-user mod or maybe there is something to possibly exploit for the expansion.

Speaking of which, any ideas?

I don't know how the hell I quoted myself.

I blame the Interweb, sorry.

OK I'm about to order the barebones.

Can I assume the barebones works with future expansions in the same way as the pre-assembled module??

I'm thinking to wait for the expansions, then stuff the module + expansions behind one face plate.

i understand that one of the things that can be changed is the filters (pre and post delay). that might be useful ....
also boosting the output to put it back in the 'normal modular' +/-5v range would be good.
about reverse delay: the idea is that the sound comes out in the reverse order then that it went in. like reversing the tape: epat eht gnisrever (yes i'm old enough to have done that as it was the only way to get that effect 20 years ago

). great sound but impossible with this chip, i'm afraid.
