The Yamaha AN1x Synthesizer mailing list

Here's a programming tip I hope you find useful:

As we all know, the AN1x LFO1 offers a tremendous selection of Waveform
variations but, neither LFO1, or LFO2, can be synchronized to MIDI
Clocks.  Or can they?

If you check the AN1x Data List that came with the Owner's Manual you'll
find a table on page 8 that converts the relative Data Value for the LFO
to a value in Hz.

Great, but how do you calculate Hz to Tempo? Well, here's some nifty
online rate calculators courtesy of Deepsound World http://www.deepsound.net/calculation.html

Most of these calculators are pretty useful but the one we're interested
in right now is the Bpm / Delay Calculator.  Enter a BPM, we'll use 140
for our example, and hit the calculate button.  The equivalent rates in
ms. and Hz. will be displayed.  If you're looking to sync the LFO to 1/4
notes, you'll notice the Frequency Rate at 140 BPM is 2.333 Hz. - now
look up that Value in the LFO Frequency table and you find the
equivalent AN1x LFO data value is somewhere in between '27' and '28' for
LFO1 Speed (or LFO2 Speed if you rather.)

After you play with this for awhile you'll notice that the values don't
translate EXACTLY for every potential BPM / Delay Time / Frequency. 
This is where you need to use your own ears and tweak to taste but it's
at least good enough to get you a ball park figure.

Hope this is of some help to all you AN1x programmers out there.  Let me
know what you think.

Regards,
Jon

P.S. - Any one into working with loops may want to check out some of
Deepsound's Calculators too.  They're pretty cool!
