Having been in the community for a few weeks now, lurking for a while before that, and developing a few Kosmo format modules I have decided now is the time for me to start sharing.
I have a few modules on my github that I shall announce over the coming days and should be on Kosmo modular grid soon.
My first module is a Quad Slow LFO, in a 100mm module.
- 4 Lfo’s
- Each has a cycle duration between a few seconds and a few minutes, approx 6 sec 12 minutes
- Each LFO has its own speed control
- A single global speed control
- CV control for the global speed (not 1V/Oct)
- Each LFO has both unipolar and bipolar outputs
I have been using the lfo for slow evolving movement of sounds, it is not a replacement for a standard lfo, normal tremolo and vibrato can not be realized with this module.
It is based on the Single-cell VCO on the LM13700 datasheet, this is a triangle wave with a big step so I added an LPF to each oscillator.
Contained are schematics & Gerber files for pcb fabrication of both electrical and front panel. This is suitable for entry-level however a basic level of electronics, soldering, fault finding, and some basic tools are required.
You will see the 6 + 1 logo in places, however, I am moving away from this imaginary brand name as I used it on a previous opensource project that I have currently put up for adoption, I have decided I’m too old to use a pseudonym and an now just going to use my name. I due course I shall be removing the old logo and not replacing it, however as I wont publish anything I have not built and tested you will see my old logo until I need to get more panels fabricated.
As with all my projects constructive criticism is welcome, all I ask is it is kept public so all the community can benefit.
