Frolic - NLC build notes 2 - completion

 This is part 2 of my build notes for the frolic module.
It's a CV & gate sequencer and a sequential switch.

The stages can be controlled by CV or by gates and triggers or both.


Part1  is here:
  • Time to place headers

  • Jacks, LEDs and pots.

     
  • The pots are all 100k, linear taper
     
    Im using blue LEDs .. my fav colour.
  • RL= 4.7k

  •  

     


.....

The finished module

  •  the first test involves plugging in an LFO to see if the sequencer works.




Nice
(Both Slew & ofset seem to need to be set to zero for the sequencer to work or have a cable plugged into the input
select jack) 
for regular sequencer functions use the hold, reset and clock jacks 

The analogue (CV) input does need some setting up and there are 2 pots
for doing this. 


The one connected to the analogue input jack is an
attenuator. For a typical 5V range CV signal, you would probably set it
around the mid-point; the input is sensitive to lower amplitude signals
(such as some of the outputs from the Sloth modules). 

The 2nd pot is to give a positive offset to the incoming CV. 
Most LFO signals range over +/-5V, so this pot will adjust the signal to make it range from 0-10V,
and then you would wind back the attenuator to get a nice motion between
stages 1 and 8. 
---------------------------------------------------

The Stage inputs are interesting.

If nothing is patched into the stage inputs, the outputs will be a
voltage for that stage, set by the corresponding pot. If you patch in a
signal, the corresponding pot becomes an attenuator for that signal.
