II. Operation

Getting Started

A good way to start is to first turn the knobs to their default settings: Shuffle, Skip, and Rotate all the way down (counter/anti-

clockwise); Slip and PW turned to center. Also, press both buttons off so that 4x Fast and Mute are not engaged. This is the

default setting for an SCM with no breakout and nothing plugged into Slip or Rotate.

A fun sample patch to try is to run a slow clock into the SCM's clock input, and use the S8 and x8 jacks to open two different

VCAs, Low Pass Filters or Low Pass Gates. Run an oscillator or some sound source into both VCAs/LPGs and mix the

outputs together so you can hear both at the same time. Now on the SCM Breakout, turn Rotate, Shuffle, and Skip all the

way down. Turn PW to 50% and adjust to suit your ears. Now play with Slip, slowly turn the knob along its full range and

listen to how every other beat from the S8 jack lands later and later as you turn Slip up. Now nudge Shuffle up until the beat

pattern changes. Play with Slip some more... keep nudging Shuffle up and playing with Slip. Once you get a feel for all the

possibilities with those two knobs, start playing with the Skip knob: you should hear some beats drop out of the S8 sound but

the x8 will continue thumping steadily along.

Using CV and the Knobs at the Same Time

To modulate a parameter, you can simply turn the knob until you get the desired result. Also, you can feed a CV signal into

the associated jack. The jacks and knobs interact as follows:

Skip, PW, Shuffle: The knob sets the offset, and the jack signal is added to the knob's setting (or subtracted when

there's a negative voltage on the jack)

Rotate, Slip jacks on SCM Breakout: The knob attenuates the jack's signal. Turning the knob down all the way will

make the jack do nothing.

Rotate, Slip jacks on main SCM: Running a signal into these jacks will add to the attenuated signal set by the

knob and breakout's jack. In this way, you can plug into the main SCM's Rotate or Slip jack and use the knob as an offset

(with nothing plugged into the breakout's jack)... or you can plug into the breakout and not the main module and use the knob

as an attenuator.

Using the buttons and jacks

The 4x Fast button and the Mute buttons act as inverters if something is plugged into the jack. This is very useful for creating

complex patterns by connecting RCDs and SCMs together.

III. Description of Controls

CV Shuffle

CV Shuffle is closely related to CV Slip, which is described in the main SCM manual (download from

http://www.4mspedals.com/scm.php). While Slip controls the amount that certain beats are pushed forward in time, Shuffle

controls which beats are slipped. The default setting is every other beat (Shuffle at minimum). As you turn Shuffle up, first

every third beat will be slipped, then every fourth beat, fifth, sixth, and finally at a certain point in the knob's range, every

seventh beat will be pushed forward.

From the this point in the range to the maximum, Shuffle behaves differently. Instead of pushing just one beat forward, it

pushes groups of beats forward. So at first a group of two beats are slipped, then a group of three, etc...

CV Skip

CV Skip is used to drop beats out of each measure. The concept of the measure is based on 8 beats. The jacks that output

less than x8 are considered to be the first "n" beats of the measure (e.g. S5 jack is considered to be the first 5 beats of a

measure).

With Skip at minimum, all beats are played. As you turn the Skip knob up or apply a positive CV, more and more beats will be

dropped out. The pattern of dropped beats is determined by a lookup table in the SCM's code. Each CV voltage corresponds

to a particular pattern in the lookup table. There are 128 entries in the table, which range from 0 beats dropped, to each one

of 8 beats dropped, to every permutation of 2 dropped beats, to every permutation of 3 beats dropped, to (nearly) every

permutation of 4 beats dropped out of an 8-beat measure. Then the table is inverted, so that it continues to 5, 6, and 7 beats

dropped. Dropping all 8 beats is avoided, since the Mute feature has this same functionality.

CV Pulse Width (PW)

Pulse Width is a very useful feature that affects all 8 output jacks. With PW at minimum, each jack will output a very short

pulse, about __ms. This is enough to trigger most other modules, but no more than necessary.

As you increase PW to about the knob's center setting, the pulse width will be 50%, which is a nicely balanced square wave.

At this setting, the amount of time the waveshape spends being low (0V) is equal to the time it spends being high (+10V).
