great news Domenico,
Rui released also Qtractor 4.8:
http://qtractor.sourceforge.net/qtractor-index.html
Rob:
one of the strong side of lionstracs products is freedom of choice for end users.
so keep the system O.S system open as possible for third party VST/ softrware.
as you see, Wine and qtractor/qranger for example changes very fast and only gets better and better.
Of course you and lionstracs can not guarantee third party software, but the base O.S that makes Lionstracs product usable for the end user should be and most be supported.
for example a Groove keyboard/rack without good working Qranger wil be nothing then trouble for end user, so Qranger must be well supported. becouse it makes lionstracs product partly what it is. so you can not say qranger is a third party software,at least that part that has changed or imparted by lionstracs software developers.
(remember this is an example and nothing else):
one example: Rui imporoves Qtractor therefore also Qranger, but you see bugs on Qranger and not Qtractor. why?
becouse here lionstracs software developers have an error in their sourcecode, So here begins lionstracs responsibility for that failure to improve the lionstracs part of Qranger sourcecode.
-----------------------------------------
but wine is another story. because user use it to run third party windows software on Linux, and of course you and lionstracs are therefore not responsible.
only support you and lionstracs can provide for wine is continue to update wine on Lionstracs O.S when new version of wine released by publisher and install demo versions provided by third party windows developers and report about that, The same goes for third party Linux software.
and one good idea is to make a list of any third party VST/software works well with wine. each new user who run third party software installed by himself on Lionstracs product can report on the list.
thanks
