Hi,
I'm new DUNE 2 user (using full registered version 2.20) since couple of days, on PC/Windows 7 Pro SP1 x64. Main DAWs are REAPER 4.75 x64 (demo) and Cantabile Solo 2 x64 (registered). All running on recent PC (Intel Core i7 4790 @ 3,6GHz, 32GB RAM). Also using a Focusrite Saffire Pro 14 (FireWire) as ASIO soundcard...
I've noticed some "artefacts" on signals when I use an "Init Patch" (selecting "VA Saw" or "VA Square"), "artefacts" on output waveform (discovered by using Blue Cat's Oscilloscope Multi VST demo). They're screen captures:
VA - Saw:

However, I precise both "VA triangle" and "WT Sine" are perfect.
Maybe somebody can give me an explanation ?
Thanks in advance.

Re: DUNE 2 VA Saw and Square: signal shape isn't perfect...Those are not artifacts, it is anti-aliasing to avoid digital noise. Sawtooth and Pulse have infinite harmonics, but all digital audio systems are band-limited. Not band-limiting properly means that ugly noise is going to appear.
Note that pretty much all commercial software synths feature anti-aliasing, as it increases the sound quality for higher notes a lot. You'll also see this when you record an analog sawtooth or pulse - in this case the sound interface performs the required anti-aliasing. Admin - Synapse Audio Software
