3 Banks

A rotary encoder is used to select the bank, while its button can be used to simulate the gate 
going high and have the module speak when pressed.

0: Digits (from 0 to 9) male voice
1: Digits (from 0 to 9) female voice
2: Spell the Alphabet
3: Nato alphabet
4: Vocabulary
5: Big numbers
6: Voltmeter (reading the CV voltage from the Sound entry)
7: Frequency meter (just saying “Hertz” instead of “Volts”)
8: Counter (each gate trigger increments the counter while any change on the Sound entry 
resets it)
9: Number radio (each gate trigger a 4 number sequence while any change on the Sound 
entry triggers a new “transmission”)
10: Timer: time elapsed since the last cv reset (each gate triggers telling the time in 
minutes/seconds while any cv change on the Sound entry resets the clock to zero)
11: Random vocabulary (53 words)
12: Sentences (13)
13: French vowels “a e i o u” (female)
14: French Digits (from 0 to 9) male voice
15: French vowels “a e i o u” (male)
16: English voiced allophones (72)
17: VCO friendly voiced allophones (25)

4 Panel

Please note that all CV pots are also acting as voltage attenuators.
When using a CV signal you may want to turn the knob fully clockwise unless you want to 
attenuate the incoming signal.

4.1 Mode Switch

The switch as 3 positions to set the mode between Speech mode (position: up) , Repeat 
(position: middle)  mode or VCO (position: low).

In 

Repeat mode

, the gate has the priority and the speech is active only while the gate level is 

high. Playing with the gate length or duty cycle allows making nice shopping effects.
