I've been showing PadSynth some attention lately, but I've come across an issue, one I'm unsure about. I'm either doing something wrong, it's a bug, or it just needs a little Rej-Tweaking. There's a pulsation issue going on somewhere. I noticed it after realising it was impossible to get a pure, non-pulsating tone out of it, or any non-pulsating tone out of it. This is odd because being an additive synth, it should be easy in PadSynth to get perfectly smooth, non-pulsating tones out of it due to the harmonics being built-up of sine waves.
Try it, leave everything off, no LFO, no anything, and no matter what you do, there's always a slight pulsating effect when holding a key down. I've literally given-up trying.
One of the beauties of additive synths is they don't suffer from pulsating effects that, for example, sample-based synths often do, so if anyone knows what's going on here, I'd love to hear what it is. I was going to put this in the bug section but thought I'd check first just in case there was something I'm not aware of that is switched on and causing it. Basically, just try to get a pure, non-pulsating sine wave out of it if you can, and if you manage it, please share the preset so that I can look at it, see what I'm doing wrong.
