As I point out in the title there is glitching if the buffer size is set below 1024 in Reaper especially in polyphonic mode and with patches that have long release times. I have a pretty decent machine (12GB of RAM, fast processor) that easily handles multitrack projects with dozens of plugins. This happens with just one track loaded with aalto.
I saw that you 've had a similar bug fix in the past but I still have this issue.
I am on Win8.1, Reaper 4.78 and Aalto 1.6
So,
In Reaper I make the DAW request the buffer from the asio driver (usually 512).I also disable the audio device from windows playback devices. I haven't been able to wrap my head around Reaper's more advanced buffering options yet.This way Aalto runs smoothly most of the time with minor glitches (cpu load around 8-20% depending on no of voices). There are instances where I'll add another vsti and things may get a little bit glitchy but this usually lasts for a couple of seconds and then everything gets back to normal.
In Live 9 things seem to run smoothly by default although with more cpu load (almost always >20%).Haven't really tried to "stress" things out with lots of plugins though
Anyhow, been making some really, really cool noises with this synth :)
So I'm going to try changing the buffering set up (try and error) and see what I can get.
Reaper does have two different cpu meters one labeled "cpu" and one labeled "cpu-realtime". The second one as I see now runs up to 40% while the first shows only 10% so that may explain the glitching in higher voice patces.
Nevertheless there seems to be some kind of erratic behaviour even if buffers and polyphony are taken into account.There are occasions where everything runs smoothly with a 40-50% cpu hit but the addition of just one compressor plugin (reaper's native reacomp-very "light" plugin) causes cpu load to skyrocket to 80% with subsequent glitching.In this case only if I unload Aalto can things get back to normal (removing the compressor plugin doesn't change anything).
Anyhow I'll post any progress I make with reaper here.I'll also try an download a demo of live to try it out together with aalto.
So I checked it with the demo version of Tracktion 6 and it still behaves the same way.The glitching doesn't have to do with aalto window being open or shut.It is behaviour similar to cpu running out of power (cause it will go away if I reduce the voices to 1 or increase the buffer size above 1024) but the cpu hit remais below 10%.Seems there is an issue with voice handling or something like that anyway.
