Yes it's a vst plug that will work in your DAW....well it works in mine....I'm sure it will but you should be able to find out for sure easily enough.
I wouldn't say it was great soundwise but I've used it to easily and quickly try out 'instrument' ideas which I then might actually mix using better sounds if I've got them. For a quid why not snap it up (I thought to myself) and....for a quid it's not going to be mind-blowing is it.....but it's only a quid.
