For generative patches we need envelopes to be A) Loopable and B) triggerable by an lfo. Also allowing lfos to trigger the start of other lfos would be good as well. This will provide a more controlled randomness as to when notes are actually triggered. For this to be truly effective Vital would need have a free mode where sound is played out regardless of whether a midi note is received or not. The only vst I know that has this is Factory by Sugar Bytes.
