I have a delay between striking a key and the sound arriving. If I haven't touched the Montage for 20 minutes or more, striking a key produces no sound, and it can take several strikes before I get the sound. I assumed that the complexity of my system was to blame, but I have now tidied it up. The mixer has gone altogether, and so has one synth - I now have just the Tyros 3 midi'd to the Montage, the outputs of which go to the Montage A/D inputs. The Montage outputs (Main L&R) go directly to the Rokit 6 speakers. They turn themselves off after about 30 minutes of non-use, but it doesn't matter if they are on or off (the first strike turns them on) I still have to strike a key 5 or 6 times to get the sound. It doesn't bother me, just wondered if this is a well known thing and curious as to why it happens. The Montage auto-turn-off is turned off - it stays on until I decide to turn it off. Any ideas?
