Ratings and Reviews

Astonishing, and beautiful.


I've been using this since the original version, and since then one stream became four and now six.
The new patch-bay allows you to send streams to other streams, or you can feed a live source and up to 5 samples through or via other streams, (or other combinations, but no more than 6) and "mangle them" (in the nicest possible way😍) and create soundscapes that are totally unlike anything you could imagine, unless you've already experienced granular synthesis.
If you love the 'found sound', music concrete and soundscapes (particularly those from industrial music or modern horror soundtracks and so on), and want to experiment in that area, there's nothing better. It does "subtle" too, and you can create beautiful ghostly /ethereal ambiences too. Having a host of ways to control parameters that effect the streams- LFO's (tempo locked or not) and extensive MIDI, so you can use a sequencer. There's nothing else quite like it out there and it's brilliant, well worth putting some effort in to discover its capabilities. Awesome. Oh and I've never had it crash, so very stable. Thanks.❤️

Can't express just how great this is...


But I'll give it a go. I have used grainulizers for years and some times happened upon interesting an useful sounds always finding it a bit hit and miss. The ability to physically interact with the controls and parameters has made it even easier to consistently harvest the most from any sound you import. I have lost hours just bouncing tracks form animoog into this thing. The addition of the ring mod and filters has now made this my go to app for inspiration. On my wish list for the next update would be a motion sequencer or an assignable lfo, or two or three (if anyone is listening ;-)

Bugged Beauty


As above regarding Audiobus and also that I can't get back to seeing all four granular strands after maximising one of them...screen seems bugged and no amount of pressing stuff is helping. It gets five stars because despite the issues that will no doubt get fixed it's one of those apps that is fun, relaxing, musical in a very inspiring way and will have you engrossed for hours.
