Any one else have problems with this plugin crackling, popping, etc?
I love the expressivity of this instrument, but I haven’t been able to get a consistent sound from it. I get a few crackles and pops peppered in each performance. It sounds like I have my Sample size too low, but CPU doesn’t seem to be struggling and I’m all the way up to 288 samples now and I still occasionally hear problems.
Could this be a sync issue of some sort? I remember in the early days of Saxophone bros by Audio Modeling, it was imperative to run the plugin in 48K or something like that.
Very hard to answer this without your providing significant information about your setup, sample rate, audio interface, platform, what other plugins are running, what the CPU meter is showing, etc
Problem Rackspace occurs in my “horn” section. It consists of two Audio Modeling Trumpets, a Trombone, and a SWAM Saxophone. Up to two instances will run this horn section at a time. Usually the problem occurs with a saxophone. Doubling the number of saxophones does not double the amount of problems.
It runs well, but not perfectly. The popping happens every 15 minutes or so, and usually when using my Sax. The CPU stays around 14-16%. When I bring the samples down to 128 CPU reaches around 22% and the popping becomes frequent. Lengthening the sample buffer seems to help, but at a larger cost than I’m used to.
When I get home from my rehearsal, I’ll be more empirical in my measurements.
I did get the chance to test a bit. I’m running on the AU version.
Here’s what it sounds like running the piano/bubble instances at 128 samples and the two saxes at 288 samples. Also, the unpleasantness happens across all the channels; bubble and piano included. The saxes were the most CPU intensive and they never got above 18%.
Using only one sax part does make the problem happen less frequent. However, I was able to catch it only using the bubble/piano and one sax instance. Same CPU readings.
Also, I’m sure that Logic exacerbated the issue. I’m going to test with the VST3 and get back to this thread.
I believe @David-san was correct. The problem was expression related.
If I map my expression pedal to CC 2 and leave it at a single value, I can play two saxes at 64 samples endlessly without crackles. If I start to add expression to the pedal, the crackling begins. The higher the resolution of the expression, the more likely the audio is to crackle.
I’ve reduced the data resolution of my Hornberg HB1 by half and now the patch seems to be running well at 128 samples.
Thank you everyone. This Rackspace was forcing me to run instances with a 288 sample buffer. It will be nice to return to a snappy 128!
