Hey you, Welcome to the Bark wiki.
Poly Mix is a polyphonic mono to stereo mixer with Polyphonic Level and Pan modulation inputs. There are 2 aux send/return and an Invert for each channel (inverts incoming audio). The poly channels are selected with the Ch. Knob so it is a 4x4 mixer. It is possible to chain the mixers together although you lose availability on Aux 1/2 on the chained modules, the first in the chain will have aux available. The Aux channels are pre Solo so if you Solo an empty channel you have a full wet effect post fader. Pan law is Constant Power for the 4 pan knobs. Mutes are post fader so you can mute a pre solo aux channel.
There is a specialised module Poly X (see below) that can be used with Level or Pan inputs as the Merge module from VCV is unable to mimic voltages on disconnected channels, which in turn mute that channel when connected to Polyphonic Level inputs. As a result of this there is an option in Poly X' context menu to send a voltage on disconnected input channels so those channels do not get muted where there is no connection on the input.
Poly X is merger with mute buttons. The way it works is the same as VCV Merge with an option to set disconnected input channels to 10v when the button is in the "Open" state (indicated by a green light - a context menu must be set as of v2.3.0). When there is an input connected you have the option to Mute the poly channel (red light indicator). The Blue light indicates a poly connection as with VCV Merge.
Clamp will limit a signal to the voltages set on the display. It is much like Trim LFO in how it operates but you can feed it any signal, The gain is applied to the input as is the attenuverter. The clamp is applied to the output. The signal is hard clipped in the same way a Limiter clips the signal, however if you set the output gain too high you will start to introduce inter sample peak distortion. There is a pad to -0.1dB button under the top display. The signal will not go over 10v unless gain is applied further down the chain after it has left clamp. When there is no inputs connected the Right channel will output the bottom knobs offset and the Left the top, just in case the need should present itself to use an offset.
There is also a link parameter's button on Clamp, when this is engaged it will link both parameters to the inverse of each other.
Trim LFO is based on the Fundamental LFO's and adds the functionality of Kinks/Utilities Logic section which can Trim/Limit the top and bottom values of the LFO keeping the original wave intact. Extremely useful for Filter sweeps, panning and sequences to name but a few uses. The clamped output will output whatever wave you select. You can set the waves by either selecting the label under the output or by mixing the waveform to suit. The phase/frequency light will track this selection. The offset/clamped parameters can be quickly set to the selected polar pattern by clicking on their labels.
Any LFO with a Square wave and a pulse width can be used as a clock. In Rack a clock usually responds to a pulse between 1v and 2v. On Trim LFO set the pulse width (PW knob) to around -49%. The frequency or BPM on the display is your clock. As a rule of thump multiply the frequency value by 60 to get the BPM: 1.9453889*60 = 116.723 beats per minute. Similarly if you want to convert the cycle's per second to a time interval you can do so by dividing the frequency: 1/0.2hz = 5 seconds per cycle, in other words it will take 5 seconds to complete 1 cycle of the LFO set to 0.2Hz.
There is a manual phase button (just under the Reset Port "RST" label) on both versions of Trim LFO, clicking on this will reset the phase to 0 and start cycling the LFO. You could sync this using any sequencer or clock or another LFO etc.
It is possible to use Trim LFO as an oscillator, you just have to speed things up. You can do so quite easily by using one of the offset outputs routed into one of the FM inputs, your v/oct can come from any source and by using the second FM input set to 100%, the display speed/frequency of the LFO becomes your oscillator tuning.
Input a Polyphonic signal, outputs a summed Mono signal based on channel number. Odd channels (1, 3, 5, 7... 15) are distributed to the Odd Port. Even channels (2, 4, 6, 8... 16) are distributed to the Even Port. There is a level Param for each distribution (labelled Odd / Even) and lights indicate total active channels. VU / Peak meters representing the summed signals value. If the signal goes above -0dB the white light will flicker indicating the threshold of inter sample peak distortion (otherwise known as clipping), in VCV Rack 10v is close to 0dB which is technically clipping also. A signal between -1dB and -2dB should always be your safe limit.
You could us Logic in a number of ways one way is to split an LFO signals min/max values.
Based on Audible Instruments Utilities a.k.a Kinks, but 4 times as logical.
