'scalingall' scales proportionally the coefficients of all its input signals and holds a constant output amplitude. Inlets (flonum from 0. to 1.) are assigned to: sig1-amp1, sig2-amp2, sig3-amp3, etc. until sig9-amp9. The rightmost inlet (number or flonum from 0. to n) is assigned to a variable threshold, default 1. The output are assigned to: sig1-scaled_amp1, sig2-scaled_amp2, sig3-scaled_amp3, etc. Coefficients are calculated according to the formula R = a*threshold/sum, where R is the coefficient of a single scaled output and a is the coefficient of the corrisponding non-scaled input.

randbank' works with scripting commands and generates random integer variables setting low threshold, high threshold and output time. After connecting 'randbank' abstraction with thispatcher object you can create a number box set to control a new variable parameters, sending a bang in the right inlet of randbank. You can start/stop the outputs of all the generated variables with a toggle connected in the left inlet ... for more info about pre-assigned labels you can see the patch in edit mode.To receive the output int use the receive object with the labels: r result0, r result1, r result2, ecc...
To send low treshold use the send object with the labels: s low0, s low1, s low2, ecc...
To send high treshold use the send object with the labels: s hi0, s hi1, s hi2, ecc...
To send output time use the send object with the labels: s ti0, s ti1, s ti2, ecc...image 1 (connection of 'randbank' and thispatcher)

'ramps' is an abstraction to make loop of ascending and descending ramps setting time and interpolation values. If the interpolation segment is not a multiple of the range it is rounded to nearest value.ARGUMENTS
1) loop (first argument): the number 1 generates a loop of ascending and descending values;
2) on-off (second argument): start and stop the ramp;
3) metro: (third argument) metronome time in milliseconds;
4) interpol: (fourth argument) interpolation value;
5) maxvalue (fifth argument): range of the ramp;
6) offset (sixth argument): optional initial value for the ramp. Note that if the offset value is egual or greater then the 'maxvalue' you can generate only descending ramps.
