Subject: Re: [AN1x-list] Re: does anyone know what units the LFO speeds are?

From: Reggie <reggie@...>

Well, I had a little think about this, the LFO value can be anything
from 0 to FF (hex) or 0 to 255 (decimal). I usually try and lock it to
what ever tempo I'm working in or divisions/multiples of depending on
the type of noise, this appears to work for a while, but it does lose
sync after a bit. That could be down to the sequencer though.



The best thing to do would be to set the LFO rate, then have a noise
that you can hear the LFO on and measure how many cycles you get in a
second or in the time it would take a bar at the tempo of LFO i.e. if
LFO = 180 then tempo = 180. If you get 4 cycles in the bar length then
it is BPM, if not you can at least work out the Hz by measuring the
cycles (Peak to Peak when looking at the wave in Soundforge) per second.
It is probably neither but a Table instead, but at least we can narrow
it down by finding out what it isn't!! I hope this all makes sense.


I'll have a look at this over the weekend sometime, probably Saturday
night.

I'm using a PLG AN, but that shouldn't make a difference.
