OK , here comes Denecke TS3 internal TC vs. Tentacle TC:
Today I started the Denecke jammed to Tentacle, 25fps, room temperature.
Direct test was 0frames off (perfect!) at 00:00:00:00
1h:20min (total) TS3 was offset 1 frame (slower than Tentacle)
5h:30min (total) TS3 was offset 3 frames (slower than Tentacle)
Rg. the price of a Tentacle its a good idea to spend a dedicated Tentacle directly to the TS3 for continous jamming – otherwise better sync it every 1-2 hrs.
