Virus Ti - Filter cutoff won't track Portamento..?

[aitch]

Hi,

Recently bought a Virus Ti - amazing machine!!
I've become very familiar with structure and programming of the Ti, but can't get Filter Cutoff Freq to glide in sync with Oscillators when Portamento is applied. I've set 'Key Follow' to max in the Filter edit section, so the Freq is tracking perfectly, but jumps immediately from note to note while the Oscillators glide as Portamento value is increased. According to page 109 of the Virus Manual, Portamento should affect both Osc Freq and Filter Freq, but apparently this is not so.
It would be useful, for instance, to play pitched Noise by applying resonant filtering (with Key Follow) and using Portamento on the Filter Cutoff Freq.
Although the Matrix section is VERY versatile, there seems no way to get around this limitation. Any ideas anyone?
Perhaps a future firmware upgrade could address this...??

Thanks for listening!

I may just be tired and answering this entirely wrong, but what about putting your synth in Legato mode as opposed to Poly?

Hi RASP,

I've already tried with all Mono legato modes as well as Poly mode, and still can't get the Filter freq to glide SLOWLY between played notes. Whatever the Portamento value, the Filter freq jumps rapidly between notes, while the Osc pitch glides slowly.
I guess it's a built in limitation, but I won't complain too much as the Virus is, in most respects, an amazing piece of kit, which responds to almost any programming trick I throw at it!
Thanks anyway for taking the trouble to reply to my post.

Best wishes,

Aitch

Yeah, amazing DSP power but its still not control voltages.

I don't own a modular synthesizer but I wonder if this is possible. Portamento on a control voltage synth is a lag processor somewhere in the key control.

Check out if there's portamento in the source list of modulation matrix. If I recall right it should be there, at least on the B-series.

Your right, its abbreviated name is "PortaSw."
