So lately I've been wanting to develop synth patches natively using resampled raw oscillators from VSTs. When I use single-cycles, I always lose some harmonic qualities of the original synth and I'm wondering about a few things:
At the DSP level, how is looping a single cycle different from playing an unfiltered oscillator of a VSTi? Is it Renoise's sound engine that causes the difference?
When using the plugin grabber, do you all have tips for getting the best quality? Long samples or cross-fade loops? I dislike the amplitude modulation (audible beating) that occurs with cross-fade loops, but single-cycle looping always has a noticeable difference in harmonic information of the signal. Trade-offs abound.
Feel free to get as technical as you'd like with explanations, I can handle it. Thanks in advance friends.
