stuHi Frits,
Ive stumbled across a bit of a problem. ive already seen some info on this topic but can’t find it now 😕 . the problem is my cpu keeps on overloading in a very irrational way. When I got the demo the first thing I did was test how many synth I could load up with out overloading the cpu. I got up to 8 along with about 12 effects, my cpu was still very comfortable(P4 3ghz). this was no surprise because I used to run more than this in cubase. When I got the real deal I started a brand new project, however ive only got up to about 6 synths this time (the same synth I used last time) and a couple of effects. The cpu meter shows about 47-50% but it keeps on shooting up to 100 constantly even though ive only added one more synth or effect I can’t understand why 👿 .
If you now wich topic the answer is in I would appreciate you pointing me in the right direction, but if not I would even more appreciate you explaining this to me.

ConquistadorHi Stu,
Would it be this CPU topic that you were looking for …?

ZynewaveHi Stu,
There can be many explanations to the CPU spikes. You say that it is the same synth you are using between the two projects, but are you using the same presets as well? And which synth is it btw? Just the slightest change to a preset can introduce denormalization issues. Also try to increase the ASIO buffer size to see if this reduces the problem.

stuthats the one but im still having problems 😡 . Ive put my asio buffer up to full(2688) And Ive now got 8 synths running and one effect. The synth I am using is called synth 1 by teksonic. I know that this synth is extremely cpu efficient its the only one I use (usually), anlong with drumatic by ephonic which isn’t that demanding either. the effect I am using is called retro delay this is also by ephonic and can eat cpu but Im only using it as a delay as opposed to using it with the reverb and distortion on. Ive tried turning down the poly on each synth and all the other usual tricks but the meter is still behaving in a very worrying way. It is now hovering between 70% & 80% but it keeps rapidly jumping up to 100%. It seems to have a constance to it, it happens around every 4 seconds. For a while it was happening every time the cursor got to the start of the 2bar loop I was working on, I don’t now if this can tell you anything. Another thing is that if I go into the browser were the file menu is it stops doing it. On average its jumping up about 25% and thats a fair amout of cpu power.
Is there any advice you can give me( configuring things differently or somthing) or is my machine just not up to it (P4 3ghz ht/ 256 mb ram).

stuAt the moment ive got my asio buffer on full at 2688 samples, and ive only started one project since getting the program. Ive rememberd somthing else now that youve mentioned that thing about presets. I set up a test project to see if I went wrong anywere when I was setting up the studio. When I looked in the a,b,c,d banks in the preset menu all my presets where there in place, bank 1 had been put in A and 2 in B and so on, But in the project that Im working on there not there 😕 . Mabye this has somthing to do with the cpu problem I don’t know.
I every time I tweak a preset I make the new tweaked version the actual preset will that help?
ZynewaveAnother thing is that if I go into the browser were the file menu is it stops doing it.
That is valuable information. I would guess it has something to do with the rate that the plugins are getting idle notifications. I’ve had difficulties with this before, particularly with SynthEdit creations. Drumatic is made with SynthEdit, and possibly Retro Delay as well. Next step would be to identify which plugin is doing the spikes. Could you try step by step bypassing (the X button next to the mapping on the track) all instances of a plugin, until the problem disappears. Start with the effects. I doubt it is the Synth1 that is causing this.
I would also be happy if you could email me your project file. I have all the plugins you mentioned, so I should be able debug the problem and see what causes this.
or is my machine just not up to it (P4 3ghz ht/ 256 mb ram).
That’s twice the CPU speed than what I am using. The 256MB memory should not be a problem with the plugins you are using.

The first time you probably had imported the Synth1 device definition file. This file is set up with the correct banks for all the presets. In your new project you probably have imported the Synth1 by selecting the dll file (or the import all command). This will not create as accurate a preset collection as the device definition file provides. Note that to reduce the size of the downloadable full version, the installer does not include the device definition files. You can download these separately.
stuFrits your right, it isn’t synth 1 that is doing this, I get the largest drop in cpu power consumption when I bypass retro delay. Ive now got 7 synth 1 instances, 1 drumatic3 and 1 rd running very smoothly (53%). Just one more thing Frits, can you describe in more detail these defernition thingies, Ive read the bit on this site about the synth 1 one but I still don’t quite know what the hell they are 😳 . The Daichi website is in japanese, is there a bit in eng, could you ponit me to were the def is.
Also I’ll have to transfer the pro file onto this machine to send it to u because its not on this machine.
ZynewaveThe device definition files can be downloaded from the same download topic where you downloaded the full version. They are just Podium project files. You won’t find them on the Synth1 website. Use the ‘import plugin definition’ command in the project wizard to ensure they are imported correctly according to the location where you have installed Synth1.
stuCheers Frits,
thanks for all your help I hope I haven’t botherd you to much, Ill get on to sending you that project file 😉
