i remember the Cuckoo video and the difference between the sound quality.
i would say the Digitakt sounds about 15% better on sample triggering.
for this reason i was nearly going to buy an mpc Live and Digitakt instead of the OTmkII.
but the Octatrack does looping and timestretching better than any other device on the market. If Akai bring the Elastique algorithm to the Live standalone mode, then maybe the playing field is different.
and yet as regards realtime performance, there is nothing even close to the Octatrack.
i still do wonder if the samples Cuckoo used in the OT vs Digitakt video had their "timestretch" setting to "off". It was just single sample triggering mirror A/B tests, so there would have been no need for timestretching to be on. And yet, by default, the timestretch is on for all samples if i remember correctly... and on the Octatrack, if it is switched off then single samples sound better.
one more thing to mention: the Digitakt is new breed programming and sounds better than any other sample playing drum machine on the market. So, therefore, it is going to sound better than the Octatrack by default, so to speak. But it doesn't do timestretching so there is the apples and oranges comparison.
For me, the choice is clear: Digitakt and Octatrack are both equally valuable and desirable for a studio or performer.
