This module provides five useful voltage processing utilities. Some are general purpose while others are designed specifically for use in LSSP patches.
Voltage to Gate
The A > 0 socket outputs a gate signal that is high (5 volts) when the A IN input is greater than 0 volts. This is handy for converting V/Bar signals into gates and also as a general purpose comparator.
One use is to convert the outputs of Time Splitter modules so that they can trigger such things as envelope generators or voltage controlled switches.
Another application is to convert the FADE IN or FADE OUT signals from Song Part modules into gates. So for instance if you want a gate signal that goes high when a particular part begins playing and stays high until the end of the song, simply patch the FADE IN signal to the A IN socket.
Bipolar to V/Bar
Directly below the Voltage to Gate element is another utility that maps a standard bipolar signal that ranges between -5 volts and +5 volts into the 1 volt to 2 volts range. This enables the outputs of LFOs and audio frequency oscillators to drive Adroit sequencers thus opening up interesting possibilities such as the creation of arbitrary shaped waveforms or complex gate signals.
Unipolar to V/Bar
In the bottom left of the module is a similar voltage processor that maps a standard unipolar signal that ranges between 0 volts and +5 volts into the 1 volt to 2 volts range. This enables things like envelope generators to drive Adroit sequencers.
The Time Flow Changer module can be used to scale up the V/Bar signals from these two utilities in order to drive Time Splitters – opening up even more possibilities.
In the bottom right there is a simple logic invertor that inverts gate signals. If X IN is below 2.5 volts then the NOT X output is 5 volts. If X IN is 2.5 volts or above then the NOT X output is 0 volts.
If no signal is connected to X IN then the NOT X output is 5 volts, so it doubles up as a DC source.
Swiss Army Knife
In the top right we have a column of four sockets that do a variety of useful things.
If you feed gates to B IN and C IN then the B IF C output is a gate signal that is only high when both B IN and C IN are high. In other words this operates as an AND gate.
AND gates have all kinds of uses, one example in LSSP is to generate a clock signal that only fires when a particular part is playing by combining the CLOCK OUT signal from Song Control with an IS ACTIVE gate from a Song Part module.
The Swiss Army Knife’s second function is as a gate controlled switch. Whatever voltage is fed to the B IN socket is passed to the B IF C output when the C IN gate signal is high (2.5 volts or above), otherwise the output is 0 volts. So you can use this facility to switch on and off an audio or CV signal fed to B IN with the gate applied to C IN.
Using two V/Bar utilities you can construct a two-way switch by using an Invertor to send opposite gate values to one of the C IN sockets.
Finally the NEGATIVE B output provides a copy of the B IN signal but with the polarity reversed. So a for instance a +3 volt input results in a -3 volt output.
