Hmm, sounds not very reliable for this issue. > > Do you have a chance to test the actual audio output to verify what the > > actual start levels of the 3 LFOs are? > > I tried this but I wasn't sure what to look for in the output.

Just a pick any sample that's immediately there (without a slow attack in the sample itself that is) and that's long enough (i.e. looped), probably some very simple synthetic sample like a raw saw or sqaure or so might be the best, then 2. in the GSt editor make sure that amplitude "attack time" is set to minimum to ensure the sample is immediately there when being triggered. Then do the actual LFO settings, for instance for LFO 1 (amplitude): 3. Set LFO's "Internal Depth" to zero. 4. Select some arbitrary LFO MIDI controller that you have there (e.g. Modulation Wheel). By default you see Controller = internal in GSt editor. 5. Set LFO's "Control Depth" to maximum (i.e. 1200). 6. Set LFO's frequency very low (or lowest) so that's easier to hear on which value the LFO actually starts. Now at the actual playback: 7. Push the assigned MIDI controller (e.g. modwheel) to its maximum value on your MIDI keyboard. 8. Trigger and hold a note on your keyboard. You should now hear LFO modulating the volume on your sample. 9. Release the note and now push the assigned MIDI controller (e.g. modwheel) on your MIDI keyboard to its minimum value, so that the LFO is now disabled=neutral. 10. Trigger and hold again a note on your keyboard. You should now hear the sample being played without any volume modulation, since the LFO is off. That way you should clearly hear the difference whether the amp LFO starts with max. volume or mid value volume. For LFO 2 and LFO 3 you would do the same steps. ---- Our assumption years ago was that GSt's LFO 1 (amp/volume) and LFO 2 (filter cutoff frequency) would start at maximum value, whereas LFO 3 (pitch) would start at mid (in case of pitch = neutral) value. Does that make sense to you?
