Hi group...

Hope this isn't too stupid a question. I like creating basslines with
tight clocked LFO's modulating the filter at different rhythmic
divisions. So 1/4 note, 1/8 note, 16th note and triplets... so as I
can jump between different locked LFO rates and apply them to the
filter as I see fit. Is there a way to create multiple rhythmic
divisions of an LFO.

cheers

Ken

Ken-  just plug your clock source into a A-160 Clock/Trigger Divider -  
you will get simultaneous clocks at /2, /4, /8, /16, /32 and /64  
rates. These can be sync inputs to drive some VCOs or wave-shaped into  
usable waveforms.

This will be possible with the planned A-143-4 Multiple Synced VC LFO. But
we have no release date so far. The prototype is too slow and we have to
make a redesign with a faster microcontroller.

to me it looks like you can do this with 147 pretty well.
the only thing your lfo needs for this is retrigger / reset
i would patch the note on / trigger signal to the reset in
and then manualy adjust the frequency at a given cv setting.
when you have 8th waving on nicely you can try to double the cv input
(by pressing a note thats one octave higher) and you should have 16th lfo.

are there any sketches about the new multi synced lfo yet ?
sounds very interesting to me.

Wouldn't the frequency divider work perfectly for this with the lfo as
the input?

hi ken,

where is your master clock coming from, midi or some analog source?

That's all we have available so far (preliminary without obligation)

Yes, but you obtain only the rectangle waveforms from these frequency
dividers.

Hi Ken,

to my experience, there is no analogue LFO which can do this.
Most of the advanced MIDI-CV interfaces provide soft-LFOs with a tempo 
that corresponds to the clock in a certain ratio. It might be a good 
idea to create a partially digital module like this:

clock in (16th) -> the clock reads waveforms out of a memory, which 
provide stepped waveforms. The clock to wavelength ration should be 
selectable, not only as divede by two ratio, but also with other ratios.
A clock-to-CV converter (doesn't have to be very exact, and should be 
quite easy to develop) controls an internal slewlimiter which smoothens 
the steps of the stepped waveform. Access to the stepped waveform might 
be interesting too.

I did a soundexample for my book, 
http://fa.utfs.org//musik/synthesizer-buch/book-audioexample-26.mp3
which uses also uneven ratios for the clock-to-wavelength relation.

Regards, Florian

Not sure if I understand exactly what you're after.

A VCLFO triggered from your computer via a midi/cv convertor should 
do it.
Amount of notes per bar will alter the sync, and modulation will 
change the speed, right?
Can all be programmed in cubase if you have a decent midi/cv 
convertor.

Or what about 3 LFO's set at the different speeds and you can swap 
using the VCSwitch module?

Or have I not understand it correctly? :-D
