using midi controller increases cpu load?
after implementing midilearn to my knobs in my actual fx plugin, i realised that using a midicontroller knob increases the cpu up to 10% more then using the gui knob?
any suggestions why this is happening?

Re: using midi controller increases cpu load?
i`m using the midilearn system which chacckl and you where creating here: viewtopic.php?f=3&t=641&start=30
i also changed the 100 ticks inside to a 25 global tick but didn`t make any difference....
i already was searching for some loops but couldnt find something..
cpu increases most when turning the knobs fast

Re: using midi controller increases cpu load?
Gui actions increase CPU usage. GDI response or something like that. Try moving very fast whatever slider or probably even mouse over gui very fast and it would have similar effect. But from what I noticed on other windows software - although it can consume 40% of CPU (according to task manager) - these are rather low priority spikes, thus they don't seem to affect operational things.
Need to take a break? I have something right for you.

Re: using midi controller increases cpu load?
i need to try look how it is when exported as vst... but in fs it only increases when using the midiknob when using the mouse on the gui it is normal, there is a big difference between mouse and midiknob, thats why im wondering..

Re: using midi controller increases cpu load?
in synthmakers registered user forum there is a knob infuzion posted a while ago+
search for heartbeat ticker
there are also some examples + tests i made related to the problem you described.
or are you talkin about a knob made with ruby?

Re: using midi controller increases cpu load?
thanks Philter, it helped a liitle bit, i tried to optimize also the ruby code of the knob, like infuzon brought some things up in the thread, and i divided the redraw limiter triggers by 2 when setting per controller this helped pretty good but it still increases more then using the mouse which makes nearly no difference for the cpu...
i posted the knob here: viewtopic.php?f=3&t=641&p=6190#p6190
to keep it in place
