Red Panda Lab Granular Delay Pitch Shift

[wolffman]

Red Panda Blog, (prototype) granular pitch shift with feedback....

This thing sounds pretty gnarly. I'm not certain there are any other granular delay/pitch shifters currently available in pedal format on the market & it appears to be coming out soon!

Do want! This would be fantastic in doom/drone stuff for background noise and build up

 

[Insouciance]

Yes.

What exactly does it do though?

Looks interesting. I have the Red Bander Bitcrusher, which I actually keep as an (almost) always on on effect in one of my loops for the electric piano kind of setting.

What exactly does it do though?

As for what the Particle does… I’m not adept enough in synthesis to describe exactly what it’s doing in detail. The most basic information I can offer is that it samples the sounds you are making in VERY small pieces- 1-50ms small- each one of these little pieces (grains) can be played back at different speeds and pitches and then layered on top of one another. It’s kind of like sampling a sound in real time and then chopping it into very very tiny pieces and mixing them back on top of each other to create a new sound.

Have you ever taken a sample of music and tried to speed it up or slow it down? If you have you’ll notice the faster you make it the higher the pitch becomes and inversely the slower the playback is the lower it becomes. Granular synthesis remedies this by taking the little pieces of sound and stretching or condensing the space between them but keeping the grains the same size.

Hmm that makes sense. So is it shifting pitch at the same time it's delaying/repeating your signal?

 

[wolffman]

I think it can shift at the same time its delaying/repeating. I dont know if it has to simultaneously delay and pitch shift. With only audio and no visual as to whats going on in real time it is hard for me to see. This is not an effect I know very much about... but it sounds trppy and spacey. def into it.

Hi guys. I've tried the prototype, and in fact made that sample in the OP, so I can shed some light.

The knob in the lower right is a rotary switch to choose between 3 pitch (orange) modes and 5 delay (green) modes. Which ever mode is selected changes how the upper right most knob, labled "param," adjusts the grains.

The pitch / delay knob controls either pitch or delay depending on if a pitch or delay mode is selected by the rotary knob. The expression input is wired to this knob (which plays a big part in the sample).

The rest of the knobs do not change function

The size knob controls size of grains, and whether the grains are "frozen" or not.

Blend knob is a clean/effect mix.

Feedback reprocesses the delay or pitch shifted signal.

So yes it can do some standard sounding pitch shifting and delay effects at certain settings, but IMO it really shines with more quirky/weird/interesting sounds for which it was designed. I'm dying to get ahold of the finished pedal!

It sounds like the TARDIS.

Great Thanks!

What do you mean "Frozen"?

Hows it sound on bass?

Great Thanks!

welcome!

Which mode did you use in the clip?

Well, it was a prototype, so it isn't going to be exactly like the final, but the mode was similar to the delay/pitch mode with feedback. The grain size was adjusted to create a droning overtone. The pitch was adjusted with an expression pedal.

What do you mean "Frozen"?

the last sampled grains are repeated instead of being constantly resampled from live input.

Hows it sound on bass?

I tried earlier prototypes with bass and it sounded great!
