EFM VCF6c Diode Ladder Filter

"The Electronics For Music EFM VCF6c is a very distinct sounding filter. It will self oscillate nicely at higher resonace settings. Changing C9 to 100 uF (or more) will extend the lower range.

It's a good idea to match all of the diodes for same forward voltage drop. I also matched Q1 and Q2 for hfe. In both cases take pains to make sure they are all at the same temperature! Let them sit in a thermally stable environment (away from drafts, windows, heat/AC registers, etc) for a while beforehand, and only handle them with tweezers or pliers. Don't hold the tweezers in your hand for long, either."

Pulse Monger demo

YouTube via synthmonger
"This is a quick demo of my Pulse Monger pedal. A limited run of the Pulse Mongers will include an internal LFO. Later versions won't but I plan on building a control processor (that's very different than Moog's) to make up for that. ;D

Here is a description of what's going on in the video

00:19 Fundamental pulse width knob is turned from fully CCW to fully CW and back again.
00:50 Mix knob goes from full Fundamental all the way to full sub-octave
00:59 Sub-octave pulse width is turned from fully CCW to CW and back again
01:15 Blend knob is set to noon (equal fundamental and sub-octave mix)
01:24 Fundamental and sub-octave pulse width knobs are adjusted from CCW to CW and back again.
02:54 Different settings are played with
03:38 The LFO is introduced at a standard triangle wave at a slow speed then high. LFO is then set to falling ramp wave from slow to fast speed, then the shape is set to rising ramp wave from slow to fast speed. Different settings are then played with.

Thanks to Leon Burnside for testing it out! ;D

**Extra notes**
This pedal has a high Overdrive type gain while it remains very quite. No background hiss or that mumbo jumbo.

The sub-octave tracks best with non-buzzy pickups. A perfectly clean line level signal sounds best.

The sub octave is great for solos and so-so for chords. Only strings parallel to one another come out clean. Otherwise it'll rattle and rumble like all non-digital octave pedals.

If you're after a truly unique fuzzy, synthy, squarey, polyphonicy and sub-octavey pedal then stay tuned as I'll have these in production soon!"
