Re: [Protux-devel] Good news about 0.17.1

[Luciano Giordana]

Arming is now only <R> ( no more <RT> ) because when you PLAY (<SPACE>) with
some track armed, protux will record on those armed track, as we discussed 
some time ago . 
IF there is no track armed, <SPACE> works like a simple PLAY. If there is some 
trakc armed, <SPACE> works like PLAY+REC .

But the recording stuff is not working yet, As I said,  it is the only part to 
adapt before 0.17.1
