DESCRIPTION

The 441 Quad Low Pass Gate is a quad 'macro' version of the West Coast LPG (NI's take on Buchla's classic low pass gate).

All 4 LPG's share the same Damp, Pluck and LPG controls.

The channels have different response characteristics (1= Slowest, 4 = Fastest).

I built this to give quick convenient access to multiple LPG's in the Reaktor Blocks Racks environment.

Level can either be set via the CV input (e.g. from an envelope) or, via the Ref switch, enabling manual control and thus the Quad LPG to be used as a conventional mixer.

When excited by a sharp-edged signal via its Pluck input, the LPG opens and closes in a natural sounding manner, giving sounds a plausible quality that is reminiscent of a drum hit or a plucked string.

ALL is a Mix sum of all inputs, and CV is an envelope follower signal derived from ALL

CONTROLS:
================================================================
COLOURED SOCKETS: Modulation Outputs (unsynchronized).
BLACK SOCKETS: Modulation Inputs.
RATE: controls the rate of all 8 LFO's.
RANDOM: crossfades between Sin/Tri shaped LFO's into random smoothed modulation.

PATHCHING COLOUR CODE:
================================================================
- Black Socket = 'CV' in.
- Grey Socket = Alt 'CV' in.
- Coloured Socket = 'CV' out.
- Red Socket = Gate/Trig Out.
- Hex Socket = Audio In/Out.

The design may go against the Blocks design protocols and best practice... but it works and it makes patching a lot quicker and fun (for me anyway).

There will be more in this range to come :)

Thanks for the kind words TF. I'm working on a few others, so once these are done I'll upload with an example Rack (I've been mostly using Bento Osc and Monark Osc as sound sources). Feeding noise into the Quad LPG and plucking/pinging the gates is also a neat and very easy way to get some percussion sounds. Cheers! Steve.

Fantastic as always Stephen. I can see how this would work well with the IC-128. I'm curious about what sound source you usually use with these, though.
