The Yamaha AN1x Synthesizer mailing list

Thanks Jon, because once again you have come up with the correct answer.
My question to Reggie would be: What synth do you know of that lists ADSR
values in actual Hz?  I've never personally seen one that does.

Check page 8 of the AN1x Data List pamphlet - you'll find Parameter 
Tables that translate the Data value to the equicalnet value in Hz for 
the LFO Frequency, EQ, Reverbs, etc.

If you don't have a copy of the Data List, check the Files section here 
at eGroups. I'm pretty certain a PDF version is there for download...

Interesting question - I see no mention in the Owners Manual, or Data 
List, of a table to tranlate ADSR, Portamento times, etc., values.

Almost every parameter value in the AN1x is a data value not measured 
in ms or Hz. Keep in mind that MIDI allows for 128 potential values for 
any MIDI CC source/dest, whether that's reflected as 0-127 or 1-128 is 
up to the individual manufacturers...

I made a post some months ago with suggestions to calculate the LFO 
times to make it easier to 'sync' them to your MIDI tracks - search the 
archives and it will turn up. Maybe I posted it on my website too - 
don't recall - check http://www.jdlx-musique.com/support/an1xpage.htm

If all else fails, do it the old fashioned way - use you ears ;-)

regards,
Jon
