messages at signal rate/low quality vibrato in vst

I'm using some Reaktor oscillators as a vst inside Max. The frequency is determined by the max patch and sent over to Reaktor. When I add a fixed vibrato to the oscillator inside the Reaktor vst itself, it sounds very nice. But when I try to make the same vibrato by adding the 'vibrato' (LFO) to the number stream in Max, which is then sent over to Reaktor, the quality just isn't the same. Most likely this is caused because the frequency-parameter of the Reaktor vst is controlled by Max's messages of which only a 1000 can be sent every second. When I program the vibrato in Reaktor itself, it works at a much higher resolution, right?

My problem is that I would like to make the vibrato myself (ribbon controller) so the vibrato can't be programmed. Is there a way to make Max send messages (the frequencies for the oscillator) at the signal rate?

Thank you.

you could abuse one of the audio channel inputs of a reaktor ensemble as modulation input so that it shows up as inlet in the max vst object.

other options as the ones known from VST3 realms are not accesible in max world.

Would it be possible to explain how you do this in Reaktor?...the software is kind of new to me, I don't fully understand what you mean.
I can't get this new inlet in the max vst object. (using Reaktor 6).

in reaktor, use for example the left channel of a LR effect to be a modulation input. then load it in max using the 2 channels reaktor plug-in. :)

I'm very sorry, it all sounds logical but it just isn't happening here : ) Would you mind taking a quick look at the 2 screenshots I added and tell me exactly what need to be done, I would appreciate it a lot. Should I use Reaktor 6.vst or Reaktor 6 FX.vst in Max? The knob in the beginning of the patch determines the frequency, it's this parameter I need to be able to update at he signal rate.

you would have to use the FX plug-in, because instruments dont have audio inputs. :)

build a mono version of your effect using the left channel, then the right audio input of the reaktor patch can be used as modulation input.
i am not a reaktor user so i dont know which filters will allow modulation at signal rate, some will, others not. and if a biquad will explode too fast, try using an FIR.

Thanks, in fact it seems like the normal Reaktor.vst object in Max does also have a second audio input (see picture).
The only thing I still don't get is why I need a filter in order to receive a signal number in Reaktor to change the pitch-knob.
I guess I just need to get a better understanding of all this stuff, I'm just too confused due to a lack of knowledge concerning the subject :)
thanks for your time!
