Title: LFO on Pitch: strange issue
Post by: Kai-vD on January 05, 2018, 12:00:56 PM

I just mentioned another issue on my Rev2: When LFO 1 modulates the pitch with a triangle wave, some notes seam to be modulated with a "defective" triangel wave: The Notes B0, C1, B2, C3 are modulated different than all others, it sounds almost like a square wave!?!

Are you running the latest BETA, 1.1.0.3? If not, please do so and see if this changes the behavior. If not, then contact our dedicated tech support for troubleshooting.

I cannot reproduce this with 1.1.0.3. Do you have a sound example and some settings how to reproduce it?

Yes, latest Firmware.

Easy settings: Basic patch, LFO 1 dest. Osc 1 freq, that's all.

That should not be all. It does not have any effect. What about LFO 1 amount and frequency? Try amount = 90 and freq = 30. I can clearly hear a continuously rising and falling tone.

It's a lot worse with these settings: The higher the amount level is, the more notes/keys have this issue.

After doing a global reset, issue is the same and additional some keys sometimes don't make any sound at all. Can't believe it...

Really strange. Maybe you should calibrate the oscillators...

Thanks, that cleared the issue!
