I can confirm that the FX/Modulation bug is still present, and that it has been added to the bug list again...
By the way; is anyone else in here experiencing that the Arpeggiator sometimes just simply stops playing while you hold down chords? ... you can usually start it again by repressing the chord, but I just wonder why this happens... it's happening frequently enough for it to be irritating, but not regularly enough to be able to reproduce anything. It also happens on non-arpeggiated sounds, thus just ordinary playing where the sound stops when you are still holding down keys.
Also... since I've had my REV2, sometimes (maybe once or twice a day) I experience a sudden "crackle/pop" coming from the REV2... it's just very briefly, sounding like if you had a loose plug, giving of a loud crackle/pop... it happens approx. once or twice a day with me while playing, and only while actually playing the keys... I've never experienced it while not touching the keys... I just keep wondering if this is somehow related to this modulation bug (I do not believe it's an FX bug anymore)... if certain situations in the engine makes the modulation of something "burst" perhaps... but again; it's impossible to find a way to reproduce it, so I've not been able to make a support ticket for this behavior.
