Sleepy-Time DSP VST Plugin Archive! (Free Download)

Dustin Ralston of Sleepy-Time DSP has recently announced that he has stopped further development of VST plugins. This is sad news for the music production community because his freeware VST plugins were among the most well-crafted ones out there. Sleepy-Time DSP plugins are beautifully designed and optimized for fast performance.

In agreement with Dustin, we have created an archive of Sleepy-Time DSP plugins below. ~~They are still available for free download from the official website and~~ the download links on BPB will serve as backup mirrors. I would like to personally thank Dustin for all the fantastic freeware releases so far and here’s hoping that we will see more VST plugins from him in the future!

Crosstalk2

Crosstalk2 is a simple plugin designed to simulate the “crosstalk” channel-bleed effect on analog systems. Some believe crosstalk adds a “glue-like” quality to the sound, helping the mix come together. To achieve this effect, place the plugin on your DAW’s master track and/or stereo busses and adjust the AMOUNT knob to dial in the desired amount.

I downloaded these, but there’s numerous option in StereoChannel that it seems I can’t use. As in, they seem to be disabled. Is there something I need to do to register or unlock the software?

for simplicity’s sake, you can email me at [email protected]

  Oh, I see ……… That’s just with the VST3 version of the plugin. The normal 64-bit VST2 works just fine.
  Others might want to be aware of that tho, just in case. :)
  Thanks for archiving these man! :)

Impossible to download TRANSIENT
Chrome detects it like a real menace and blocks it.
Oh boy…

The manual, as well as some comments mention VST3 versions? Where are they?
