Instrument Editor Lfos Out Of Time

[whippycranium]

just been trying to get a decent vibrato from renoise by using one of the instrument editor window’s LFOs on the pitch envelope. LFOs (with frequency of 4,8…etc.) should be in time with the pattern as it loops but they are not. It seems like it is the same problem as with the vibrato pattern effects command. the LFO cycles slightly too fast for the pattern and sounds poppy as the pattern loops… hope this can be fixed in a future version of renoise, accurate vibrato by pattern effect commands or pitch envelope LFO would be really useful. at the moment still must use an LFO device

It’s not really a bug, it’s just that the instrument LFO behaves in a different way.

You should check out this other thread from a while ago: Lfo In The Instrument Editor

I’ll quote my own reply from there:

@dblue

The instrument LFO is one of the things in Renoise that has not really changed much since the very early days, so the values you need to use there can seem a bit strange at first. The good thing is that the LFO does actually remain in sync with the song BPM, although it is not really connected to your LPB (lines per beat) or TPL (ticks per line) settings in the way that you might expect.

A value of 15 will cause the LFO to cycle once per beat. A value of 30 is twice per beat. Etc.

Here is a quick list:

• 15 = 1 cycle per beat
• 30 = 2 cycles per beat
• 45 = 3 cycles per beat
• 60 = 4 cycles per beat
• 75 = 5 cycles per beat
• 90 = 6 cycles per beat
• 105 = 7 cycles per beat
• 120 = 8 cycles per beat

As you can probably guess by now, getting exact cycles of 0.5, 1.5, 2.5, etc. is not possible since they would require LFO settings of 7.5, 22.5 and 37.5, respectively. In those cases you just have to accept the slight loss of accuracy and use the next best LFO setting. I’m sure the instrument LFOs will eventually be improved to allow for a greater range of accuracy and flexibility, but for now this is what you’ve got to work with

thankyou! i had no idea that the instrument editor lfos needed different values…so, does the vibrato command work using these values as well?
