Today I faced an issue with high CPU usage and Pianteq.
In my rackspace I am using the MIDI Filter to block NOTE ON messages.
This is working fine, but I noticed that Pianoteq was using CPU and no sound could be heard.
Then I investigated and found that NOTE OFF messages sent to Pianoteq consume CPU.
This is because NOTE OFF messages are processed in this plugin - what is good for a real simulation of a Piano.
The solution was - in this use case it is possible - to filter out not only NOTE ON messaged but also NOTE OFF messages.
I know there is a danger of hanging notes …
Autchhh… the price of realism; but its like this from many versions back (note off = keys lift “noises”)
Im yet to update, too much on my “plate” right now (maybe later tonight) .
Do you mean that you tick the 2 boxes note on and note off ?
Or do you tick NOTES ?
I use NOTES to filter incoming notes and I do not have more CPU usage and no hanging notes (I guess this option is proposed to filter note on and note off at the same time).
When I filter Note On in the MIDI Filter plugin the cpu usage is high
But when I filter Note On in the MIDI In plugin, the Note Off message come not through - which is desired
because a Note Off Message for a non existing Note On is not necessary
