I notice that when using Organteq, even configured to use all 8 cores of the i7, only the first core is used and when I use large polyphony with full organ, the first core goes from 100% instead of looking for other cores to work, inside or outside the DAW, which is not the case with other software where there is a perfect distribution between the cores.
It is a strange situation you mention. I suspect some setting should be modified to give Organteq access to the full processor power: Please go under 'Options' to 'Perf' to find information of the processor. And make sure that the checkbox 'Multicore rendering' is activated.
And that your operating system (which?) allows that as well. Under Windows start the task manager via Cntrl-Alt-Del and check under the tab performance the number of physical cores.
Second: type msconfig in the search window and run that program as adminstrator. Go to the boot tab and the box 'Advanced options' and make sure that the check box next to 'Number of processors' is UNchecked. That should allow Windows to use all cores. After OK, restart.
I use Organteq stand-alone on a PC with W10 Prof and I7-9700K as processor running at 3.6 GHz, audio at 384 samples at 48 kS/s. The 8 cores are working hard when full organ is used with 12 keys pressed, but it manages without overload.
Sweelinq is a sampled organ with reverb added, and required much less processing power. On that topic it can not be compared with Organteq.
