LFO panning : Bug on 0.27

dtgn

Hi there,

The LFO seems to have some trouble when applied to "voice panning" destination :

 2) On voice 1, 2 and 3, it only goes from left to center (with the MIX pan parameter set to 0). In order to have it covered the whole left-right spectrum, you have to turn the MIX pan parameter to +64. If turned to -63, it simply get stuck on the left side.
1) On voice 4, 5 and 6 it doesn't work

I noticed this in the code the other day. Voices 4 5 and 6 are not wired up to any pan modulation, and the first 3 only pan left. If it's easy enough to fix, I'll push it with my next custom feature (which should be within next few days).

Great to know the issue has already been spoted in the code ! Thanks for your feedback.

regarding point 2:
this is due to the way modulations are handled at the moment in the LXR.
To simplify the coding quite a bit, modulations are done like this:
'actual parameter value' * 'modulation value'
so the parameters are always modulated between 0 and the set value.

to point 1:
i found the problem. I implemented the pan handling for the drum voice (1-3) but somehow forgot the copy the fix to the other voices. I will fix this for one of the next releases.

Ok, I understand point 2 and why you have to have a set value at +64 to have the full spectrum.

panning value is actually 0 to 127 - (but is displayed as -63 to +64 to be helpful)

 

The LFO ranges between 0 and 1 and simply multiplies the panning value - so the maximum value is whatever the parameter is set to, so to pan full right you need the value set to +64 (127)

just uploaded another firmware version (0.30) that should fix the pan mod issues for snare, cymbal and hat voice

Whaou, that was quick ! Cheers, I'll try it soon.

I've pulled this fix into the my custom firmware now.
