How can I make a pure sine wave? I chose a sine wave sample, set the length to 10 seconds, but I find that no matter what I set the crossfade to, there are notes where I can hear when the waveforms overlap -- if I adjust the crossfade on one note so that the sound is perfectly continuous (as far as my ears can tell), when I try other notes I can hear slight regular modulation (at different frequencies for different notes. I'm trying to make a pure continuous sine wave -- equally continuous at any frequency.

P.S: Are samples on the Wavestate the only ways to initiate sound? (In other words where other synths have oscillators, the Wavestate has samples.)

Load your sine wave sample into the first step of the sample lane. Then set the 1st step of the timing lane to "Gate" instead of "Step" or "Rest" (Upper right corner of the timing lane step screen) Setting the first step to gate will stop the wave sequencing and produce the simple sine wave you are after.

Thank you! ("Gate" wasn't what I expected.)

If you're definitely not going to be switching waveforms, another way is to press the Wave Sequence Select button (next to the screen) and set the mode to Single Multisample and then choose the Wave: Sine sample from that screen. That disables wave sequencing for the layer.

This method has the added benefit of halving the number of voices used; wave sequencing seems to always require that a second voice is queued up for every voice played, regardless of how the wave sequence is set-up.
