Yesterday I had the chance to spend some extended time with my unit, created a pretty simple poly patch and even had time left for setting up a proper recording session. Unfortunately, I started to experience audio drops away once in a while which of course ruined the recording
CPU usage was at around 42% and I had three external tracks coming in for recording. Since I didn’t have problems at the beginning of the session of course I suspected heat being the problem. I have the ER-301 above the PSU in a case that isn’t ventilated properly and it was on for about 2,5 hours so…, fair enough. I need to find a good solution for that. I took it out right after the session to check the amount of heat however and I must say I wasn’t impressed. I was warm, but not actually hot anywhere. What are your experiences and recommendations? Is there any other factor that might have caused the audio dropping?
I am going to start fresh today and record that session with a cooled down unit. Hope that will work out.
I don’t believe overheating will exhibit itself this way. If it ever did overheat (which would be difficult) the ER-301 would just shutdown.
The first thing that I would do is check that the patch is indeed consuming a maximum of 42%. If you would like me to take a look at your patch, please drop the quicksave file here.
Also, a short clip of the audio drops that you recorded might be helpful.
just from listening to the audio file it doesn’t sound like a cpu problem, it sounds like a gate is modulating a filter, the slew when it comes back is quite pronounced. i once had a similar “dropout” sound when i was modulating the filter too much (with an envelope follower i think), are you sure it isn’t just closing the filter?
True. I will get back to this patch today and try to make a proper diagnosis. I was a little afraid of overheating trouble so I might have jumped to conclusions!
Wait a sec. The slew is because it’s processed externally so even when it is a straight drop out from the er-301 it would sound like that when it goes through the effects and filters before its routed back into the er-301 for recording.
hm, ok, i don’t know the setup of your patch but maybe try to record the patch directly, without routing externally. a cpu dropout doesn’t just happen without warning, eg some crackle and clicks, at least that was the case when i had quite some issues with that. but i never experienced such long dropouts…good luck!
You were right @kilchhofer. I just fired up that patch and monitored the raw er-301 output. There were some drops in the main output but not in the er-301! Because of some gate complications with my fh-1 there was indeed an envelope closing a filter exactly like you said. Seems like I need an fh-1 expander to fix this, or a logic module that would combine the gates in my poly sequence.
Fals alarm @odevices! Happy about that, myself
glad you found the error. this is a very inexpensive or combiner:

Glad to hear it got sorted @Bparticle. Good job with solving the puzzle and thank you @kilchhofer for helping out.
People should start putting hours of modular use on their resumes because it is a clear indicator of honed problem-solving skills.
