Dear all,
Thanks the great work of Antoine Bouchereau, Daniele Ghisi and Yan Maresz, we finally fixed all the problems related to the Partials and Mel descriptors optimization and the new release (0.9.1) is available for download (do not worry, there is no need to download the sound database again). This leads to a great increase in the quality of solutions ! We also fixed numerous little bugs with the interfaces and the computation core. I hope you can now enjoy the system as much as we do 
Do not hesitate to send us your (positive or negative) feedback on the quality of solutions and the overall application, so that we can make the software even better !
All the best,
Philippe
