I have used Granulab in its standalone form for years. It's programming heaven - or hell, because it isn't geared to necessarily making pretty sounds.

The new VST version is pretty much like the one-voice standalone. The standalone provides a lot bigger control interface with finer controls, but I'll get used to the interface - or not. I don't care.

The way I will use Granny VST is that I'll pop in a weird sample and have at some granular synthesis for an hour or two, not necessarily playing to record it or insert it into other tracks. Just tweak away, making noise. IT IS SO MUCH FUN.

I consider working with Granny to be an industrial electronic music meditation. YM will definitely V.

I started using the standalone version of GranuLab around 2010/11, and it hasn't left my taskbar since. I've tried lots of granular software over the years but nothing has managed to knock it from the top spot. I use granular synths for microsound / sfx type transformations (a la Curtis Roads) rather than making nice pads, which is what a lot of granular software seems to be aimed at recently. The ability to transform between preset states as well as set slower / faster parameter change times is the clincher for me. Fantastic for live use, I just record long takes and edit out the best bits.

Particularly chuffed that I can now simply drag and drop files from my host sequencers browser, which speeds up the workflow immensely. Fantastic to see that a vital bit of software is now being updated again.

This is the best granular effect i have tried with the exception of permut 6. This thing is great. Please finish and I will buy.

Very creative and appealing plugin right of the bat. It has tremendous potential but is a bit confusing and unpredictable in its current form. Being able to trigger the clips with MIDI would be a must to make it my go-to granular synthesis engine.

Visually, this is a winner for me: I particularly like how the effects curves are displayed and tweakable! I had never seen this before.

I'm giving you 5 stars so you can win and finish the plugin because it's a keeper.

this would easily be a better VST if it was an instrument.

instead of effect its got alot of potential.

I love this concept, and the layout ideas are brilliant, it's a neat tool to do wild experiments for sound design... But either I'm missing something big, or this is completely unplayable as an instrument?

Wow! Loving this so far. I love the GUI and how responsive it is. The functions are sometimes a bit obscure, but it is conducive to experimentation. I concur with the other reviewers: making it into an instrument would be fantastic as right now it plays and stops in unpredictable ways. I particularly love how this effects windows displays the curves... I had never seen this before. Where can I find you on social media so I can give shout outs?

Hi all, thanks a lot for reviews & comments.

Sorry for not replying sooner, didn't know until last few days that there was yet another place to interact.

I've been busy trying to get Granny into a state of "basic sanity" or something like it.
Fixing crash bugs, getting it to run on MacOS versions, and now saving params/patches in host projects like all other VST's do gets me much nearer that sunny place.

There are still several crazy-town things going on. Lack of start/stop button, host interaction and several behavior options spring to mind.

But now is also the time for some fun stuff, rounding up and designing the remaining features.

Any requests, suggestions or comments (especially complaints about all the shit that doesn't work like any musician with half a scoop of mango sherbet for brains would want) are very welcome, and will be disputed, reconsidered and integrated with pleasure.

So much for official statements.
- Regarding "playable as instrument" I''ve talked to one user, hopefully it was partly fixed when I got MIDI monosynth in place, but you tell!
- I'm not on social media much, or at all really, the webpage and KVR and email (in docs and on the webpage) are best chances of talking.

Why dont you have a panic button for god sake, making every DAW crash if your not fast enough to dischard the thing!.

Make it an instrument and then i would pay 50 bucks for it. BUT ...i realy like the plugin for its response and smart intuitive controlls!.

Hej Pelle.

The real problem would be the DAW crashing.
Does it actually crash or is it more of a lockup due to many long grains (=high density), making sound stutter and granny be unresponsive?

Which DAW?

I'll never let you pay any amount, but I did consider a start/stop button, it's a good idea to actually clean out the overflow grains too.

Will do sometime soonish.

Cheers, .

Hi Rasmus.

This plugin looks wonderful. I do own a few other granulars, but I'd really like to get to work with this one. Unfortunately I cannot seem to find it with my DAW when adding the file to either of the folders -->component or -->vst or -->vst3 on my Mac. I am using Mojave (10.14.6) and StudioOne v4. I have even tried to rename the file so it had a .vst extension, but no luck so far. I would be very happy if you or anyone could guide me in the right direction - if there is a solution :).
