They are so damned good and reasonably priced. I've already spent more money on presets for this one synth than all the others combined. The only real problem with this awesome piece of kit is that it is hard to resist the presets for sale in the Arturia web store. But I'd still recommend it without reservation. Be warned, some of the more elaborate presets can be hard on your CPU. But Arturia Pigments is in a league of its own. I also own Serum, Massive, MassiveX, FM8, Absynth, Reaktor 5 and 6 (which include some very tasty soft synths) and others. And the factory presets are surprisingly good. The UI is artful, pleasant to use, well organised. To me it seems my CPU is more than suited for these kind of tasks.The sound is gorgeous. The thing is it doesn't seem to matter that much if I increase the buffer size, also when I monitor my CPU with task manager or the dedicated Ryzen software it barely goes above 30%, and this is with a browser, spotify, whatsapp etc running in the background. I have a MOTU Ultralite mk3 which is connected via FireWire, I don't have the Hybrid version so no USB option. I am running Live 9 64 bit on Windows 10 with a Ryand 8GB of RAM, samplerate is 44100 and buffer size all the way up to 1024. As soon as I switch the 4th on it shoots to somewhere between 90 and 130%, turn it off and it goes back down. When I disable the 4th instance everything is fine, and cpu sits around 40%. I realise the sampler engines are most CPU heavy.

All four of them have 2 engines with the sampler running and 6 of those use granular. I have four instances of Pigments running and the fourth one seems to take up 50% of the CPU load, Pigments is always heavy on my cpu but it looks like something different is the issue.
