Is anyone's laptop good enough for key lock in all situations?
I run Traktor Pro 2.1.2 on my MacBook Air 2.13 GHz Core 2 Duo. Not the fastest out there, but meeting the minimum requirements.
The CPU runs pretty cool for the most part, but gets pretty hot when (1) tempo shifting between -86% and -76% (2) with key lock (HQ/Normal mode) on. The good news is that it's not quite enough to introduce any audio drop outs or any overload related artifacts that I can tell of. But the bad news is, when I scrub a track to prep for the next mix, it almost always generates a glitch or audio dropout in the sound playing out - usually the other deck. I'm pretty sure this is related to the CPU spike when pitching down a lot, because scrubbing often makes Traktor key lock at a very slow speed.
So, my question is, does anyone's laptop - I mean if the specs are high enough - work just fine with the key lock (HQ/Normal mode) regardless of the playback speed?
If the majority is having a problem here, I thought it would be something for NI to consider addressing.
Surely, there is the "scratch mode" that forfeits key locking at around -30%. Perhaps this is established as kind of a mean-point geared towards the needs of Scratch users that most definitely want the pitch to change when they change the rotation speed of the vinyl via scratching.
Not that great as a CPU-saver for non-scratchers though... If one pitches down big time with key lock on, he's usually expecting the time stretching effect that "normal mode" offers -and even does so without necessarily dropping out (sorry this is based just on my laptop). And even if to prioritize stable audio over the desired effect, -30% is way too early to give up. I bet most laptops can push it a lot further.
Given that scratch users are satisfied with the scratch mode, I propose both of the following for the non-scratch users.
(1)Adjustable safe mode. Disables Key lock at pitch fader % values the user can specify.
assuming that might be a hassle...
(2)Active mode. Disables Key lock when neither playing or cueing.
I actually did a workaround to get (2). I just mapped key lock to hold with my cue button, and toggle on/off with my play button. Easily done for the mappers, but perhaps good to have as a configuration option too?
