Your English is just about oké, man!

What makes you think I look at Brazil as a banana country? All I know is that there's a great dutch song about Brazil (Vengaboys)

Awaiting your comment about the booster...

Peace!

"You can also create a PWM (Pulse Width Modulation) like effect by using a Tone's waveform (WG1) as an LFO to shift the other Tone's waveform (WG2) up and down. This parameter works best when you use it in conjunction with the Gain parameter (PATCH/WG/Wave Param)."

This effect works best when using a particular set of waveforms. I also believe the quote is backward. WG2 moves the WG1 up and down. It affects WG1 wave's DC offset. When the wave is higher it clips the top off the WG1 waveform. This changes the waveshape. If you use a triangle wave (or even a saw wave: say B26) for WG1 and a low wave (I like B189 Low Sine) for WG2, with the right settings for the gain, you will hear the WG1 waveform morphing. As the wave gets more clipped, it's perceived pulsewidth changes (a triangle is broader near the base than near the peak). This effect is similar to a trick they used to do with the old analog synths where they would use an LFO to modulate the pulse width of a wave (good for a chorusd effect without the chorus). Since the JV/XP's don't have pulse width modulation per se, they described (badly) this work-around in the manual. Hope this helps.

PS: There is a better description of this effect in the supplemental notes PDF files available at rolandus.com

Thanks, Jerry.

The supplemetal note is far better than both printed and electronic manuals for the JV1010.
It explains very well the "booster LFO effect" (sic).

Yeah! Thanks guys, this is what I've been looking for. This PDF supplemental note explains it!

Jerry, You're right. WG2 affects WG1 and not backwards. That's What it says in the note too. You rightly mentioned that this is badly described in the user manual.

I figured whether we should report this to the Roland Company, but they'll probably treat it as a minor issue anyway...

Still my doubts about the TVA (first problem) are not really gone, I still don't see the way in which TVA1 acts when using a booster.

------------------

Pierry,

I believe the quote about TVA´s is also backwards...so WG2 affects WG1 and TVA2 should control the booster...
