Maybe someone has insight on this:
I’m sending hi hat trig and pedal control midi to superior drummer (running as vst in ableton) and I’m really satisfied with the overall sound and realism.
Problem:
I can hear artifacts; a certain crunchiness comes from the samples that are played when I transition from a closed to an open hi hat using the pedal control.
I would describe it as distortion, but it’s more like a bit-reduction kind of sound or the crackling that happens when system resources are being overworked by audio applications. I’m using a maxed out 2015 Macbook Pro and Superior Drummer doesn’t seem to be using any more ram or cpu than any of the other VSTs I use such as Kontakt.
My diagnosis:
I believe what’s happening is that all the multisamples that make up the gradient of hi-hat sounds are cutting each other off, so I’m hearing a string of samples stopping and starting super rapidly with all the little tiny clicks that come from samples changing at points other than zero-crossings in a given waveform. It’s subtle, but it’s definitely audible and it makes the difference between recording a real hi-hat vs using Toontrack.
Troubleshooting:
I don’t get the same effect when using Native Instruments’ Abbey Road stuff, and I don’t have any crackling with the pedal samples within my electronic kit when I use its native sounds. That leads me to think that it isn’t an issue with my midi controller sending jumpy data. I’ve played with the controller curve in the mapping section to no effect. I’ve also attempted to use a max for live device that smooths out the cc and that didn’t seem to have an effect either.
Is there any way to adjust SD to reduce these audio artifacts?
