The 4th beta is now available for download.
Along some bugfixes, the main feature added is the Arpeggiator panel which allows control of the arpeggiator on the Blofeld with a nice plus: the plugin displays graphically the arpegiator like on the synthesizer. While this display is not 100% accurate at this time, it is already usable.
This is not necessarily a major feature (but cool, isn't it?), finally having the arpeggiator working is a major step in the project because the bulk of the parameters are now available.
While there are some parameters still missing, all efforts can now be put on correcting the remaining bugs and aim at a first version of the plugin allowing total recall of parameters.
