Swell/Delay with the Transient on the Repeats

[turdadactyl]

I'm thinking of a circuit where the initial sound would swell in, but then it would repeat and the repeats include the initial attack.  Seems it would be VERY difficult as you'd have to time the "pre-delay" to be equal to the length of the initial swell.  This would probably be easy with a purely digital pedal.  Can it be done with analog technology?

Unless you've described it wrong, whatever one imposes on the real-time signal would also be imposed on any delayed repeats.

Or are you thinking of something where the effect is only imposed on the real-time but the delay repeats are unaffected?  If this, then it's really a simple matter of a splitter.  The input signal ets fed to a splitter stage.  One half of the splitter goes to the effect you describe, and the other output goes to the delay path.  Job's done.

That's precisely what I'm thinking.

You may be right and I may be over-complicating this.  Any thoughts on the idea that the delay effected signal should be "pre-delayed"?  Otherwise wouldn't the signal to the delay path pass through and compete with the swell, lessening the swell effect?

DIY delays generally have two separate paths: a dry path for the original signal and a wet path for the delayed signal. These two paths are usually combined with a mixing amp before they hit the output.

For your delay sidechain, take a standard delay circuit, don't include the dry path, and use the mixing amp to combine the delayed signal with the swelled signal path. You might have to adjust some of the mixer component values and/or buffer the output of the swell circuit, depending on the circuits you choose. Figure that part out on the breadboard.

I think you're over-complicating it.

The delayed side doesn't need to have any non-delayed dry signal mixed with it.  All you're doing is applying an effect to the "dry" signal path.

If you want a further wet/dry mix to dial in the amount of unaffected dry signal you could add that at the end but it sounds like you probably don't want that.

It sounds like you just want a swell effect followed by uneffected repeats.  This is straightforward so don't confuse yourself by over-thinking it.

I can think of other crazy things you can do like applying the swell effect to every-other repeat but that requires 2 delay lines so you can apply the "pre-delay" to the swell before mixing it into the dry side, then feeding into final delay effect, but it doesn't sound like this is what you have in mind.

Yep, that's exactly what I'm after.  Ok, so I'm going to stop over-thinking and start figuring.  To be continued...
