I run VST on a mac. Giga is randomly unstable - we all know that ! - sometimes ( a lot today) I can be editing midi data in the key edit page, on a totally different channel to giga & the pc crashes. Mostly if the sequence is going. I do use USB midi on the pc (not on the Mac) which people will say is bad, but latency isn\'t my problem. My problem apart from the obvious pops & clicks we all seem to get, is crashes when I\'m editing another channel....Any one help ??
