"Sosir Freeze-Delay" (for guitar?), free VST3, UPDATE 0.9.2 more features. Now for Mac too!

[liqih]

New in Sosir 0.9.2:
1. Beautiful new freeze sound, the "Mellow Tone" selection
replaced the previous "Standard"* choice.
2. HighPass filter in freeze stage.
3. Slow Stereo LFO added as modulation source of the Delay Time.

*( if the "Standard" freeze tone selection was you favourite, in 0.9.0,
please let me know)

Windows VST3 AND Native Mac build AU/VST3

Enjoy!

### some info ###
The idea of "Sosir" was to create a bowed sound (by freezing the input)
from a plucked sound (roughly speaking: guitar pluck to bowed strings).

You have basically two stages:
1) digital virtual bow
2) delay line with feedback and modulation by LFO
(There is also a small reverb at the end, but that's optional).

You should use the "Sound Choice" selector to change the base timbre
and duration of the bowed sound.
Then you have the other controls to adjust it to your needs:
"bow" dry/wet, sub octave doubling, filters LowPass HiPass.

When the delay Time is set to about the same or less of the "arcata"
duration, the repeats (by delay feedback) would merge in a long
sustained sound, this make it sound more like the infinite reverb you
know.

Note. That there are two different "Wet" controls:
the mix of "bow" effect and the mix of delay effect.

The idea is not new, someone may call it a poor-man Strymon,
anyway I couldn't find any free plug-in to do these sounds.
What you think? Love, hate, room to improve it?

Here is a 1 minute demo, the same acoustic guitar phrase played in loop
and the Sosir effect goes from 100% Dry to 100% wet, during the minute time

into C:\Program Files\Common Files\VST3 and let your DAW rescan the plugins)

I think its pretty cool, turns any sound into NI Absynth. Absynth has a lot of bad presets so this plugin makes it a lot quicker to manage.

Thanks very much for taking the time to try it. I know nothing about Absynth (I mean I never tried it), my reference was the "Swell" preset of Strymon BigSky.
Maybe "Freeze-Delay" is a wrong name for it isn't it? Should I call it Swell-Dwell-Delay?
Or Swell-Reverb??

I was playing guitar with this for quite a bit last night. Interesting concept. Is this an IR(s) from the Big Sky pedal, pure DSP or a hybrid of both?

Funny because i have a patch i created on my Zoom CDR-70 that employs this same technique, which is kind of a Slow Dive/Yamaha SPX Symphonic patch hybrid but it has the Boss Slow Gear effect block as the first effect block in the chain. I use it on my bass board for ethereal intros and transitions. It’s kind of the effect Mike Gordon, bassist of Phish, uses for the ambient middle jam sections of the songs YEM (You Enjoy Myself) and Harry Hood. I’ll post a clip of the song my band uses it in.

Pure DSP, there are ir samples used in the convolution, but I generated them by code,
I haven't sampled any gear. (I don't own a Big Sky pedal anyway).

Thanks, indeed using before input a Slow Gear or a similar attack ramp effect would help to control the rise time.

Thanks for this. Had a quick play with it and it seems quite nice.

FYI Airwindows does a version of this (two actually) called Galactic(2). His stuff is open source so, hypothetically at least, you could see how he does it and if it suggests any features or approaches to making your plugin.

Thanks Joe, I will check those links.
Also I will happily take any suggestion/request from anyone here, as long as doesn't make my Sosir effect more complicated.

oh! Galactic2 sounds very nice! But it's a reverb*, different from Sosir that it's also an echo with repeats mingled with the pad sound,
here is a very very short example of delay with halo : sosir_echo_on_synth.mp3

*[edit: I've see there are many other plugins by Airwindows, so maybe the same effect is covered elsewhere (?)]

Linux support would be nice

Yes it's made differently but the end effect is certainly in the same realm of generating a tonal wash based on audio input. At the risk of exposing my own ignorance, doesn't the difference between delay and reverb often come down to amount as much as anything else?

There's also the earlier Infinity2 which can expose the underlying delays more at low setting of the allpass control. https://www.airwindows.com/infinity2/

I think the only conventional delay he makes is called TapeDelay2. Which is nice but not really built for ambient.

[Tj Shredder]

I can’t test it, as I am on Mac. But it simply sounds like a delay/loop going into a washing reverb. What does it exactly? There must be a reason you call it delay…

[paramita123]

I'd really recommend to add a Hi Pass filter then it's easier to choose the frequency band for the FX.
Ducking could be useful.
A really fantastic free plugin worth emulating or comparing to is DEELAY, astounding feature set especially diffusion, reverse, duck, just a killer free plugin.

[liqih]

Thanks for asking, the concept for this plugin is in evolution.
Now the idea is to use custom ir convolution to create a bowed sound
from a plucked sound (roughly speaking: guitar to cello).

sosir_0.9.2.png

As you can see in this screenshot (new 0.9.2 I'm working on),
you have basically two stages:
1) digital virtual bow (by convolution)
2) delay line with feedback
(There is also small reverb at the end, but that's optional).

A] The "digital virtual bow" does so far sound similar to a washing reverb,
but it doesn't have the decay or the spectrum of a reverb impulse.

B] Due to the convolution technique. the bowed "sound" is mostly
with slow attack, though it will be adjustable from about 100 ms to
2000 ms. Currently there are just selection with fixed times.

C] When the delay Time is set to about the same or less of the "arcata"*
duration, the repeats (by delay feedback) would merge in a long sustained
sound, this make it sound more like the infinite reverb you know.

D] Also there are two "Wet" controls:
the mix of "bow" effect and the mix of delay effect.
That kind of control is quite different from the usual delay+reverb wash
effects.

(*arcata is the act of moving the bow)

More filter features, yes! Ducking, not sure, anyway a dynamic response could be nice.

Thanks Luigi ... demos sound great.

[liqih]

And here is a quick and dirty demo of the bowed sound with the delay off:
synth "plucks" dry first and then 100% wet (but no delay or reverb)
