This is really not bad for freeware and as a taster for the pro version, it is very interesting indeed. It is very simple to use, important for those who have never used a Sampler before. However, the ease of use would have been improved if it had a manual of some kind and the GUI was a little more typical of the VST format. The GUI is certainly minimalistic and very clear but perhaps a little perplexing if you haven't used software synths for a while.
The Sound quality was quite good, the filter and ADSR is useful and easy to understand.
There are no presets, however, since it is a sampler this probably isn't a problem for most users. However, a few demonstration samples would make up for the lack of manual.
Previous versions were apparently incompatible with other multisample vsti's such as SR202 etc. However, this seems to have been remedied as I can no use it.
