Improved LFO/envelope sample rate

      Improved LFO/envelope sample rate

      Hello!

      Fresh owner of a Virus TI here, loving the synth so far. Coming from mainly software background, I often find myself twiddling with the knobs and making all sorts of sonic adventures that I get immersed in for hours. The Virus is definitely a great timewaster. ;)

      However, while using extremely fast LFOs and envelopes, the modulation tends to be too stepped. I examined a waveform I recorded using a fast LFO and figured that their sample rate is 44100/64 Hz (at least when running Virus at 44.1 kHz). That's adequate for most cases, but I would really love if there was an option to run all LFOs and envelopes at higher rate, say, 1/4 of audio rate or even at audio rate. I understand this would require extra DSP power, which is why it would make sense to have an option for it. Not having that option seems like a missed opportunity for more "analogue" modulation and trickery.

      I'm not a DSP coder myself, but I would imagine this could be done relatively simply with an OS update. Thoughts?
      Have you tried using the Adaptive Control Smoothing? See page 129 of the Virus TI User Manual.

      Smooth Mode
      Right from the very beginning, Access have been applying a technique called “Adaptive Control Smoothing” (ACS) in all their synthesizer models, thus avoiding the zipper noise that rapid changes (knob movements, modulation) would otherwise cause.
      > Off: Smoothing is disabled. Pros: Value jumps are immediate, with no glitches. Useful for gater-effects etc. when using a sequencer. Cons: Continuous control changes are incremental, meaning you may have to accept some zipper noise.
      > On: Smoothing is enabled. Pros: Continuous control changes are smooth, so this setting is generally the better option. Cons: Sometimes too slow for intentional rapid jumps e.g. gater-effects.
      > Auto: Control changes are analysed, and smoothing is switched on or off depending upon how fast these changes are. Pros: Smooth and sudden control changes can be applied to the same sound. Cons: Rapidly repeating jumps may be too fast to analyse correctly.
      > Note: Smoothing is disabled, any changes are only heard at the start of each played note (not inbetween). Pros: No glitches. Cons: Smooth transitions not possible.
      > Quantize 1/64 ... 1/1: Smoothing is disabled, any changes only occur at rhythmic intervals relative to the Tempo, expressed as a 4/4 bar division. See “Tempo” on page 129.

      No, because I figured it only affects the actual knob movements and not the internal LFO/envelope modulation routings. I tried changing the Smooth Mode and it had no effect. The LFOs and envelopes still run at the same rate. Have you had different experiences with changing it?

      Thanks for replying!
