The original TesslaSE plug-in came out sometime in the late 2000s, if I’m not mistaken, and garnered a cult following for its smooth analog saturation. If you’re one of the many fans, rejoice! We’re finally getting an update. TesslaSE MkII is based on the same tried-and-true concept, but with a slick new interface, improved gain staging and a few tweaks to the transformer/tube circuit modeling algorithm to make it even better. And it now runs in 64 bit. Now, how about a Mac version?

TesslaSE MkII is a VST plug-in for Windows (32/64 bit).

BPB has released Dirty Spring as a Black Friday freebie. It’s a cool little spring reverb plug-in with pre-delay, decay, tone and mix controls for adjusting the reverb’s character and effect amount. Interestingly, it also features a built-in bitcrusher for added grit and crunch and that classic 8-bit sampler effect. There’s also a kick button that mimics the effect of physically bumping into a hardware spring reverb. Great stuff if you’re into vintage, lo-fi sounds!

Dirty Spring is available for macOS and Windows in VST, VST3, AU and AAX formats.

Here’s an experimental synth with a delightfully geeky edge to it. According to the developer, NANDroid is a noisebox synth with four square wave oscillators feeding NAND gates – hence the name. Those gates then feed another gate. There’s also a filter, a bunch of modulators such as LFOs and a delay effect. NANDroid produces some pretty wacky, noisy sounds – if you’re into experimental sound design and unusual synthesis concepts, be sure to give this one a try.

NANDroid is a VST3 plug-in for Windows (64 bit).
