It’s not the same as the outcome of rendering in place of the said part. It’s not totally random, as the sample depends on the source material (I guess), but it’s super glitchy and sounds like a small snippet is time stretched a lot, and the process itself takes way too short in comparison to rendering in place.
Steps to reproduce:
create external instrument
create a midi part with notes on the external instrument’s track
drag the part to sampler control tab.
listen the the sample created in the samplertrack.
Ok. A little correction. The result is the same when an empty midi part (which doesn’t contain any notes) is dragged to the sampler control tab. The resulting sample contains basically a digital noise which has to be normalized within the sampler track to be heard at all.
So I guess the issue is nothing is rendered when an midi part (with notes) from an external instrument track is dragged to the sampler control tab.
I don’t get any noise here, when I try to drag and drop an empty MIDI Part from an Instrument track (with regular VSTi) to a Sampler Track. Is this what you did, please?
Please use “Normalize sample” in Sampler track after.
edit: Yes. There is no noise when dragging an empty midi part from VSTi track. The recorded noise must be coming from the inputs of the audio interface.
edit: That gave me an idea, that actually something is recorded, so I generated constant audio from a synth and dragged an empty midi to the sampler control tab as stipulated earlier.
Mind you that it doesn’t matter, if there are any notes in the midi part or not. Cubase ignores them anyway and just records whatever is going into the channel at the time the sample is created and destroys the sample.
