- LITTLE DUCK FILTERBANK
-
- made by Mikko Hyyrylainen
- created with Jeff McClintock's SynthEdit
-
-
- Version 1.1 (compiled with SynthEdit 0.71)
-
- ------------------------------------------------------------------
- History:
-
- v1.1
- -minor update: fixed the output from two separate mono outs to one
- stereo pair out and labeled it with more informative name (now it's
- a little bit easier to use in Cubase SX). Thanks to Sahul from
- Elogoxa group for pointing that out.
-
- v1.0
- -first official release
-
- -----------------------------------------------
-
- Overview:
-
- This VA stereo filterbank has a retro look that might
- upset you, but don't worry, those knobs work just like
- the rest. The arrow on shows the current value on the knob
- in a same vay those old guitarknobs used to do (yes, I am
- a guitarist).
-
-
- Filter Section:
-
- There are five filtermodes in Little Duck. 4 pole Low Pass,
- 2 pole Low Pass, 2 pole High Pass, 2 pole Band pass and
- 2 pole Band Reject. ENV modes are the same filters with
- envelope follower. FREQUENCY controls the filters cutoff
- frequency and Q controls the resonance.
-
-
- Envelope follower:
-
- There is two ways to trigger the envelope: BOTH uses the
- stereo input signal itself to trigger the envelope and LEFT
- SC (Sidechain) is a special mono mode where Right signal is
- the carrier that is affected and Left is a modulator that
- is only used to trigger the envelope and is not heard. SO
- when you use the LEFT SC mode you must route the affected
- signal all the way to the right with pan and triggering
- signal to the left.
-
- TRESHOLD determines when the triggering signal starts to work
- in a way that lower the treshold, easier it is to trigger the
- envelope. Sometimes when the triggering signal is too low or
- constant (not enough dynamics) the envelope follower might not
- work as expected. The LAG is control for simulated lag processor
- that softens the triggering signal with lowpass filter so that
- when it is higher only very loud or bass signal peaks trigger
- the envelope. This is useful when you want that only the kick
- drum of the filtered loop triggers the envelope for example.
-
-
- Envelope:
-
- The envelope itself is a simple Attack Decay envelope. ATTACK
- is from 5ms to 315ms and DECAY is from 10ms to 2 seconds.
- It is important to know that the envelope cannot be retriggered
- while it is is still working so you can get decent sweeps. ENV
- DEPTH controls the amount of envelope. ENV +/- chooses between
- regular increasing mode and inverted one where the amount of
- envelope decreases the cutoff frequency.
-
-
- Triangle LFO:
-
- There is a internal beats-per-minute pulse clock in Little Duck
- that can be used to sync the LFO. You can manually select the
- BPM tempo with each digit and then the LFO RATE determines how
- long it takes that Triangle LFO to move its whole wavelenght.
- For example if the rate is set to 2 bars then it takes two
- measures (at selected tempo) to sweep up and down. The rates
- ranges from 8 bars to sixteenth notes and there is alse certain
- triplets to choose. The LFO DEPTH controls the amount of LFO.
- It is good to bear in mind that LFO sweeps both up and down
- (positive and negative) so you should set the FREQUENCY according
- to that. For example if you use full depth then it is wise to
- set the FREQUENCY at least at five so the filter doesn't close
- totally at the nadir of the LFO.
-
-
- IMPORTANT!!!!!
-
- If this unit starts to misbehave in some unexpected and erratic
- way, you should reset your host's sound engine.

- -----------------------------------------------------------
-
- LITTLEDUCK is tested with Sonar 1.3 running DirectiXer 2, Psycle
- 1.66, and Cubase SX. It has also been reported to work in Orion,
- Logic and Massiva too. If the knobs introduce crackles to the
- sound in Psycle,you should increase the latency.
-
- THIS PRODUCT IS TOTALLY FREE SO USE IT AT YOUR OWN RISK!
-
- BIG BIG THANKS TO JEFF.
