1D  Min/Max  Gate  X  Y  min( X, Y )  max( X, Y )  The Z knob/CV provides a gate function. When Z goes higher than approximately 2.5V, the gate goes high and the outputs follow the inputs according to the min/max relationship. When Z goes below approximately 1.5V, the gate goes low and the outputs are frozen. 
2A  Lin/Exp Converter  Hz/V scale,centred on 1kHz  exp input  lin input  lin output ( 2 ^ X ) * scale  exp output log2( Y / scale ) 
Z sets the scale factor which is common to both conversions. It sets the number of Hz per Volt, with arrange from near zero to about 2kHz. The Yamaha CS15, for example, uses about 1100Hz/V, which is about half way on the Z knob here. The zero Volt point on the exponential scale used is C3 (approximately 130.81Hz). 
2B  Quantizer  scale & fct of Y  Input  [Z>0] transpose [Z<0] trigger 
quantized( X )  trig on note change  When Z is positive input Y is a transpose control. The CV on input Y is quantized (to a chromatic scale) and added to output A (after input X has been quantized to the chosen scale). When Z is negative input Y is a trigger. In this mode, input X is only sampled and converted to a new quantized value when input Y rises over approximately 1V. (In nontriggered mode, X is constantly sampled and a new note is output as soon as X moves into the next semitone range.) 
2C  Comparator  hysteresis  X  Y  gate X > Y  inverted A  Output A is a gate signal (zero or +5V), high when input X has a higher voltage than input Y. Output B is an inverted copy of A (i.e. +5V when A is 0V and vice versa.) 
2D  Dual Waveshaper  Gain  X  Y  fold X  triangletosine Y  The Z knob/CV is a gain control, with a range of approximately 30x. Negative values of Z invert the signal. 
3A  Sample&Hold  slew rate  Input  Trigger  X when Y exceeds 1V  noise ±8V  The Z knob/CV controls the slew rate of output A. At the minimum value of Z, changes in A are instantaneous. As Z increases, changes in A take place more slowly 
3B  Slew Limiter  slew rate  X  Y  linear( X + Y )  log( X + Y )  Outputs A & B are both slew rate limited copies of the sum of X & Y. Output A uses linear slew rate limiting; a step change in the input will typically result in a ramp output, until the output reaches its desired value, at which point it will be constant. Output B uses logarithmic slew rate limiting; a step change in input results in a smooth curve that gradually approaches the desired value. The Z knob/CV controls the slew rate for both outputs. At the minimum value of Z, changes are very rapid. As Z increases, changes take place more slowly. 
3C  Pitch&Env Tracker  slew rate for env  X  Y  V/oct of (X+Y)  envelope of X  This algorithm provides pitch and envelope tracking of an incoming audio signal. It will track frequencies down to about 27Hz. Knob/CV Z sets the slew rate of the envelope, controlling how quickly it tracks changes in level 
3D  Clockable Delay/Echo  feedback  Input  Clock  dry + wet  wet  Input Y is the clock input. Any clock pulse in excess of 1V can be used. The time between rising trigger edges is used to set the delay time. If the time between triggers is greater than the maximum delay time, the time is divided by two until it is small enough. This way, you always end up with a rhythmically useful delay time.

The scale is an integer (whole number) which either multiplies or divides the frequency, and ranges in value from 116. 
4C  VCO linear FM  tune ±0.5 oct  1V/Oct pitch  linear FM input  sine  saw  The Z knob/CV provides a tuning control, with a range of approximately ±0.5 octaves The A and B outputs provide sine and saw waves respectively, with an amplitude of ±8V (16V peaktopeak). 
4D  VCO waveshaping  tune ±0.5 oct  1V/Oct pitch  waveshape / PWM  saw > sine > tri  pwm > sqr > pwm  The 0V point for the pitch input is C3 (approximately 130.81Hz). The Z knob/CV provides a tuning control, with a range of approximately ±0.5 octaves. Input Y controls the waveshape of the output signals. Signals in the range ±10V give the full range of possible waveshapes: Input Y 10V 0V +10VOutput A saw (falling) triangle saw (rising) Output B 0% duty cycle pulse 50% duty cycle pulse (square) 100% duty cycle pulse
