Do any of you guys know if the A110 can be used as a VCLFO?

If it would I think it would be a better value for monet than the 
VCLFO itself...

Thanx, Zameer

You can make the A110 go lower
than you expect.  Freeze the clock
sequencer at any stage, patch that
stage into an inverter.  Take the 
output of the inverter and patch it 
into one of the cv inputs on the A110. 
You can get down to decent lfo levels 
that way.

I used to make my VCLFOs that way 
until I purchased an A147.

You might add a capacitor parallel to C3 (upper half in the middle above
O5). For the values I'd had to experiment. I'd start with a value of 10nF
additional.

Which makes me think that, maybe the voltage source (A-176) should 
have a negative output instead of the cv-3. -Would be a lot easier.

the voltage source a176 gives you negative voltages
on all available outputs.
there is a jumper on the board for every output.
you can select between -2.5 to +2.5 v or 0 to +5 v.

you just can't get -5 v directly from the a176.
therefore a mixer or an inverter is needed.

The A-174 joystick makes a handy CV source too, using just 
the 'offset' knob  - gives out about +/-4V on both channels.

Pretty neat, Ethan. I got my A110 down to about 0.5Hz with the CV 
source patched thru the inverter.

The A147 VC LFO, OTOH, goes down to about 1 cycle per MINUTE by 
itself. Patch the same negative voltage to it, and you can use it to 
time paint drying.
