Utility 1

Features

The Utility 1 module was developed to allow for the generation of user-controlled manual gates.

Additional features were added to make the funcions more utilitarian.

A push button activates the M(anual) Gate output. A green LED above the output indicates that the gate voltage is present at that output jack.

The M Gate is momentary and is active for as long as the push button is pressed.

The Latched Out output activates when the push button is pressed and remains on until turned off by the next press of the push button. A red LED above the Latched Output indicates that the gate is present at that output jack.

The /2 Out is a continuation of the process and the output toggles on, then off for every cycle of the Latched out. A blue LED above the /2 Out jack indicates that the gate is present at that output jack.

A clock was added to the module to allow for clocking the gate outputs automatically. The Clock Rate adjust the clock speed between ~6Hz to 70Hz. The Clk Out jack outputs the clock (0-10V) directly for timing syncronization.

The Manual/ Int-Ext switch allows the clock to be routed to the gate network. When the switch is in the Int-Ext mode, manual gate operations are suspended and the clock drives the gate network. The M Gate Out follows the clock while the latched out produces a gate every other clock pulse and the /2 Out generates a gate every 4th clock pulse.

The Pause button suspends the clock from the gate network, drops the M Gate to off and allows for "pauses" or for syncronizing the gate pattern to a sequence.

The Ext Clk in jack allows for external clock sources to drive the gate network. The Man/ Ext-int switch must be in the Ext-Int position. An extenal clock applied to this jack overrides the internal clock into the gate network but, the internal clock is still available at the Clk Out jack.

The Man V-out allows for setting a ~ +/- 6V DC that is present at the Man V-out jack. The voltage can be used for CV offsets, VCO tuning adjustments, etc.
