H90 delay question (feedback oscillations)

[sigitar]

I have a specific delay question, specifically about feedback oscillations.

I like being able to oscillate a delay with a hold and then further influence the delay tail using tap tempo.

In my opinion, the UAFX Galaxy Delay does this best. I’m trying to replicate this with the H90, but unfortunately, I’m not quite succeeding.

My goal is for changing the delay time (tap tempo) to cause not only the tempo but also the pitch to increase (or decrease) continuously. The emphasis here is on continuously! Unfortunately, I can only achieve an abrupt change. As soon as I change the tempo, the pitch and tempo change instantly! Not gradually increasing/decreasing. I can only achieve this with headspace, and unfortunately, not as smoothly as the UAFX Galaxy.

I’d like to achieve this with an external aux switch, assigning one to tap and the other to (feedback) hold.

Does anyone have any tips? Is my goal achievable?

Hello,

Head Space would be your best option for this. Can you elaborate when you say it’s not as smooth?

Bouquet Delay can also do this effect, but the BBD feedback will oscillator much quicker than Head Space.

With the Galaxy, the pitch rises continuously with the number of oscillating repetitions. With the H90, it’s abrupt and springy. I hope I’ve explained myself clearly, especially since English isn’t my first language.

I have a few ideas that I’ve yet to confirm.  Are you absolutely locked into using Tap?  I do think there are ways to achieve this with Tap, but I have some other approaches in mind as well.

Also, since it’s a ‘Roland Space Echo’-style emulation, are you looking to stay with a tape effect?  When I read “pitch rises continuously with the number of oscillating repetitions”, I immediately thought of a Crystals type of effect, including the new Cosmic Web granular.  That would be more of an ‘automatic’ rise or fall in pitch.

Thanks for the tip. I hadn’t even considered granular effects, and I really like the Cosmic Web for my purposes. It could easily replace my current effect.

Although it doesn’t have much to do with my original intention – as I said, my reference was the UAFX Galaxy.

The Cosmic Web is extremely interesting, but difficult to control (which isn’t a problem for my purposes).

I had high hopes for one of the REPEAT performance options, but I didn’t happen to land on any ‘pitch-shifting’ options.  As @tbskoglund mentioned, the Bouquet Delay SELF OSC with Tap is a workable solution, a bit more difficult to control.  But for a ‘Space Echo’ template, you were already very close.

I believe you were using an Aux-to-HotSwitch for your “(feedback) hold”?  Here’s another thought, one that can be momentary or latching.  In addition to mapping Feedback to the switch, try adding on a change in Delay times.  Shorter delay to ‘pitch up’, longer delay to ‘pitch down’.

This isn’t going to work in any crossfading Delay algorithm, but it will in any tape-like delay.  (A different kind of setup in the Sticky Tape algorithm, but with similar pitch-bending).  The aforementioned Head Space will work here, as will some others.  Like any of the Delay algos, it’s very easy to go overboard with the oscillations, so it takes some careful tweaking.

Basically, it involves switching Feedback UP and Delay time (DOWN or UP) at the same time.  Again, it does take some fine-tuning to control the ‘range of pitch’ from the Delay extents.  Despite being a switched option, I think it will satisfy your “continuous” requirement.  It’s something I do often with an expression pedal, as that can have more versatile control.

Thank you for the input. I’ll take a closer look at it this weekend and get back to you…
