NekroBat LaborOsc, A Free Software Synth For Windows


There’s a lot of discussion on a recent post about Prosoniq discontinuing Windows development because of piracy. Some people think there are just more Mac pro musicians, while others think that Prosoniq’s pricing is just too high for the PC platform.

Here’s another reason that companies like Prosoniq may be abandoning Windows, though: there’s a lot of competition from great free music apps for PCs.

For example, check out NekroBat LaborOsc – a freeware VST synthesizer for Windows.

  1. I demoed it in Minihost and XT2. Apart from some gravelly noise for a second after you change presets, it sounds great! It’s a diffrent sound from Synthedit and varity is always good.

  2. “It’s a diffrent sound from Synthedit” yes, because, it’s a SynthMaker synth, and it sound like other SM synth, flat.

  3. I just stumbled across this synth today, and being the VST Junkie I am,first glimpse at the GUI and I snapped it up in an instant. It is sweet and I was amazed at the sound quality from the moment I loaded it and hit the first note. I haven’t had any problem with unwanted noise switching presets as others have mentioned. But I’m not switching while the synth is playing…don’t know if that makes a difference. I already have it as a “standard” in a personalized FL Studio
    template. And I can’t pay it a bigger compliment than that. Thanks again NekroBat!

  4. All I can say is… Thanx!
    All credits go to the wonderful people at the Synthmaker forum for every bit of learning (and some of the pieces of modules and graphics I have used). I could NOT have made this without you! I am eternally indebted, and grateful! I hope this will show what a great piece of software Synthmaker is!
    Yours truly!
