I've mentioned this several times... (why I didn't fully explain in my above response)
Intro for "Turn Me Loose"
Synth Engine 1: Multi-Saw x2 (set to 5th)
Synth Engine 2: Shape Sine Saw (set to Octave)
Synth Engine 3: Shape Sine Saw (set to 9th)
Enable Portamento for each Synth Engine... and set it to maximum time (it's just barely long enough for the 2-octave slide up).
Save (Store) the patch.
Play a few different patches (to simulate a gig situation)... then return to the Intro for "Turn Me Loose".
What happens is that Portamento is not functioning on Synth Engine 1.
Synth Engines 2 and 3 glide up to pitch as expected... while Synth Engine 1 immediately plays the G5+D6.
This doesn't sound quite as bad as playing a half-step out of key... but it's a close second.
This bug was introduced after firmware 1.06.
It's been broken since... and remains broken in firmware 1.14
I understand bugs happen.
I've reported this issue directly to Nord... and other than the automated response, there's been no acknowledgement (and obviously no fix).
For covering vintage synth type sounds, having properly functional Portamento is fundamental.
It's frustrating that it's been broken this long... and who knows when/if it'll be fixed.
At the very least, it would be nice if Nord/Clavia would respond/acknowledge the issue.
Also, why in the world would Nord/Clavia decide to purposely (severely) limit the maximum Portamento time?
Bad decision. Better to have too much and not need it... than to have too little and be SOL
If NS4 had the same "user-tunable" intervals with mult-wave oscillators as in NS3, we could work around the issue by avoiding using Synth Engine 1.
As is, NS4 users are limited to preset intervals of 5th/Octave.
Thus, it takes all three Synth Engines to cover what two could do in the NS3.
I came to the NS3 late... but the experience was far more smooth.
Had I realized that many NS3 samples would not be present... and that Portamento would be broken (for many months), I'm not sure I would have upgraded.
Loved the NS3... which is why I was one of the first in the US to get the NS4.
NS4 has great potential...
It would be nice to see it get some attention (firmware updates).
