Mini PEG is the company's advanced envelope generator' Pingable Envelope Generator (PEG) ' is a downsized single-channel version that retains as many of the main functions as possible.Smoothly crossfade through 9 different clock-synced, loopable envelope shapes with CV control.

  • Envelope/LFO synced to clock
  • Tap tempo and clock input
  • Clock division and multiplication from /32 to x16
  • Smooth crossfade between 9 waveforms
  • Attenuverter (Scale) and offset controls affecting the main outputs
  • Dedicated +5V envelope output
  • EOF output that can be used for other synchronous events

HOW TO USE

Mini PEG is a 'pingable' envelope generator that sets the envelope time by the length of time between pulses (pings).Pingbutton orPingYou can set the tempo by patching an external clock to the jack.
This 'ping' clock thenDiv/MultIt is multiplied or multiplied by a value from 32 divisions to 16 times depending on the knob and CV settings.The resulting envelope will be the period length of this divided/multiplied clock,ShapeVarious waveforms can be selected using the knob and CV.Also, this envelopeScaleOffsetYou can also use the knobs to scale, invert, and offset.
To create a one-shot envelope,triggerSend the trigger to Jack.CycleActivate the cycle with the button or CycleThe Mini PEG also works as an LFO, as it continuously generates an envelope when the jack is gated high.

Ping

tap tempo

PingSet the Ping clock period by tapping the button twice. If the third tap is executed, it will be the average value with the first two taps. If the third tap sets the timing period significantly different than the first two taps, then the second and third taps are used.If you want to use visual feedback according to tapping,Div/MultSet the knob to the ' = ' position.This allows you to play at the same tempo as tapping. PingThe button flashes.

Synchronization to external clock

For synchronizing to an external clock or gate signalPinguse jack.The timing between the last two pulses received by this jack sets the ping clock. Unlike the Ping button, the Ping jack does not average the incoming pulses and simply gets the period between the last two pulses. If you connect a module like Manual Trigger/Gate to the Ping jack and tap it only twice, the ping clock will keep running at that tempo without sending any more trigger pulses.note that,System ModeThen thisfree runningIt is also possible to deactivate the function.When disabled, two external pulses will output a single envelope and stop.See below for detailsSystem ModeSee section.

PingIf a gate signal is input to the jack, the tap tempo clock will be disabled.In this case, tapping the Ping button overwrites the external clock. Try tapping a fast tempo with a slow clock on the Ping jack.The fast tempo will be adopted immediately, but will return to the slow tempo when Jack receives the next clock pulse.

clear tempo

To clear the tap tempo,PingHold the button for 2 seconds.The button will go dark and the envelope will stop.Also, externally generated pings can be cleared if the external unit stops sending pulses or is unpatched.


Div/Mult Control

Once the ping clock is established,Div/MultUse the knobs and jacks to divide or multiply the tempo from 32/1nd speed to 16x speed by whole numbers.This resulting clock defines the length of the envelope output and is the period of the ping clock multiplied/divided.PingThe button flashes. Mult/DivThe knob has a detent mechanism at each of 19 positions,Div CVAny CV coming into the jack will be added to the knob's setting.

Changing the division/multiplication value while the envelope is running will immediately change the slope of the envelope.the module isSyncor sending us a message onAsyncEither mode may cause the envelope to be resynchronized to the ping clock.See below for detailsSynchronous mode and asynchronousSee Modes section.


Trigger Jack

Activates the envelope with an incoming trigger signal.By default the envelope will start immediately and the module will be in asynchronous mode.Holding the trigger high also has no effect.In system mode, this jack can be configured as a Quantized jack, so when a trigger is received the envelope will be output on the next ping clock.For this usage, the module will go into sync mode when it receives a trigger, and if the Trigger jack is held high, the envelope will cycle until it returns low.This jack can also be configured as an 'Async Gate' jack.This is the same as the default behavior (Async Trigger), but the envelope will persist if the gate is held high past the end of the rise phase (End of Rise).The fall phase begins when the gate returns low.In asynchronous mode you can re-trigger an already running envelope, but not in quantized mode.described laterSynchronous and asynchronous modesandSystem ModeSee also the section on


ShapeControl

ShapeKnobs and jacks control both the slope of the envelope (skew/ratio of rise and fall times) and waveform (logarithmic/linear/exponential) selection.While there is a continuous spectrum of waveforms, the range can be divided into three zones.

The first zone is from the far left until about 9:30.As the knob is turned clockwise, the envelope begins with an exponential rising sawtooth and gradually transitions to a linear rising sawtooth shape.

The transition from zone 10 to zone 00 goes from a linear rising sawtooth to a balanced exponential shape (equal rise/fall times) around 2:00.The second zone starts with this shape, transitions to a balanced linear shape at the middle position of the knob, then transitions to a balanced logarithmic shape around XNUMX:XNUMX.

The transition to the third zone morphs from a balanced logarithmic shape into a linear descending sawtooth around 2:30.The third zone is the inverse of the first zone shape, starting with a linear falling sawtooth and ending in an exponential falling sawtooth shape.

The input range of the dedicated CV input is -5V to +5V.


Shift

CycleHold down the buttonOffsetBy operating the knob,ShiftYou can control the amount.This is similar to Offset, but with envelope offset and scale applied.laterApplies. The DC level of the Shift amount is the centerline where the Scale knob attenuates or inverts the envelope. Shift basically shifts the scaled/offset envelope up and down, causing clipping on the -9.4V and +9.4V rails.By default Shift is 0V, the most intuitive setting. Any envelope voltage (amplitude and offset) that the Mini PEG can generate can be created without adjusting Shift.However, with a proper understanding of DC offset, amplitude, inversion, and clipping, adjusting Shift allows the Scale knob to invert the envelope at voltages other than 0V, which can be useful in special cases. 


EOF Jack

End-of-Fall (EOF) jack outputs a gate that goes high when the envelope's falling phase ends.If the envelope stops, the jack stays high.This jack goes low only when the rising phase ends and the sustain or falling phase begins.In system mode, this jack can be configured as 'End-of-Rise Jack', 'Half-Rise Jack', or 'Tap Clock Output Jack'. End-of-Rise goes high at the beginning of the descending phase (remains high if stopped) and goes low at the beginning of the rising phase (remains low if sustained). Half-Rise goes high at half the rise phase, stays high for the sustain period, and goes low at half the fall phase. Tap Clock works without limits even when the envelope is not running,PingOutputs the raw ping clock before division/multiplication by tapping the button without being affected by the external clock.Detail isTap clock outputSee section.
EOFThe jack outputs a square wave by default, but in system mode it can be configured to output a trigger instead.

Maximum and minimum clock period

The Mini PEG processes the incoming clock and outputs an envelope signal up to about 4kHz, with some jitter, glitches and imprecision. When outputting frequencies above 500Hz, the output contains more noise and glitches, but retains the substantial underlying frequency and waveform. Since Mini PEG can also run at audio rates, it can also be used as a rudimentary lo-fi harmonizer (sub-octave generator).When used as an audio generator in this way, keep in mind that even a small amount of clock jitter at the input will cause noticeable and perceptible distortion and glitches at the output.

The maximum envelope time is approximately 29 hours (1750 minutes).The maximum ping clock period is also about 29 hours, let's say once a day,Pingwhen sending a clock pulse to the jackDiv/MultThe setting must be ' = ' or multiplied to get precise output.

Synchronous and asynchronous modes

Mini PEG can work in Sync (synchronous) or Async (asynchronous) mode.In most cases, the difference between the two modes is irrelevant and changing modes is automatic and intuitive. Syncmode, the envelope always starts and ends synchronously to the multiplied/multiplied ping clock, AsyncEnvelopes in modes can start at any point.in this way,Syncmode locks the phase of the envelope and the multiplied/multiplied ping clock, whereas Asyncmode allows you to create a phase difference.

Change Sync and Async modes
  • SyncMode is set as 'Quantized Trigger Jack'triggerSend a trigger to Jack or set to 'Enter Sync Mode'CycleSend the trigger to Jack.See the System Mode section below for how to configure each jack.
  • Asyncmode is set to 'Async Trigger' or 'Async Gate Jack'triggerSend the trigger to Jack.
  • CycleHold down the buttonPingTap andCycleYou can also switch modes by releasing the button.

SyncIn mode, the Ping button is cyan,AsyncThe Ping button flashes white while in mode.

Fig.1 above shows the envelope in each mode.SyncWhen the Mini PEG starts cycling in mode, the envelope starts synchronously with the ping clock pulse. When the Trigger jack (Async Trigger or Gate mode) receives a trigger, the envelope will immediately reset and continue cycling out of phase with the ping clock.Now the module will automaticallyAsyncmode has been changed.

Cycle button in Sync and Async mode

CycleWhen using buttons, it's good to know in which mode the module is working. SyncWhen the Cycle button is turned on in mode, the envelope will immediately start outputting in phase with the ping clock.This can be imagined as an envelope always running in sync with the ping clock, and unmuting it with the Cycle button.

As Figure 2 shows, this causes some interruptions, but the envelope is always in sync with the ping clock. Turning Cycle off stops the output after the current envelope finishes. AsyncWhen the Cycle button is turned on in the mode, the envelope will immediately start outputting from zero.One or more full envelopes are always output, but they are not ping clocked, but synced to the Cycle button as shown in Fig.3.

Div/Mult Modulation in Sync and Async Modes

while the envelope is runningDiv/MultIf you change the amount of , the module's response depends on the mode being selected.In either mode, the slope of the envelope will follow the Div/Mult amount as long as the amount continues to change. In Sync mode,Div/MultIf there is no change in 50ms, the envelope will resync to the ping clock based on the new Div/Mult values.

In Fig.4 the Div/Mult knob has been changed from '/2' to '=' at the point of the black arrow.The envelope quickly transitions to a new envelope synced to the ping clock between the black and red arrows.Even if you change the envelope length, you can still see how all envelopes start and end on the ping clock. In Async mode, the envelope does not need to be synced to the ping clock, allowing smooth transitions between waveforms without resyncing.

Figure 5 shows that the envelope follows changes in the Div/Mult amount, but does not require resynchronization to the ping clock, indicating that the envelope does not necessarily start/end on the ping clock. understand.

Using the trigger jack in each mode

triggerWhen the jack is configured to 'Quantize' and the trigger is entered, the module will wait for the next multiplied/multiplied ping clock before starting the envelope (Fig.6). If the Trigger jack is configured for 'Async Trigger' or 'Async Gate', the envelope will start immediately upon receipt of the trigger, regardless of whether the ping clock is present at the same time (Fig.7).

Rephasing a Trigger configured to Quantize

In Sync mode, when Div/Mult is set to Divide and the Cycle button is on, sending a trigger to the Trigger jack set to Quantize causes the envelope to be restarted (re-phased) with the next incoming ping clock .For example, if Div/Mult is set to ' /4 ', the ping clock represents quarter notes and bars can be counted as ' 4-1-2-3-4-1-2-3 '. increase.The envelope starts at '4', peaks at '1', and ends at the next occurrence of '3'.If you send a trigger to Quantize's Trigger jack between '1' and '2', the envelope will be rephased and start at '3' (Fig.3).

Tap clock output

EOFThe jack can be set to output a tattempo clock.This setting isSystem Modewill be done.When set to tap clock, a clock corresponding to the tapped tempo will be output from the EOF jack. Unlike setting the EOF jack to 'End of Rise', 'End of Fall', 'Half-Rise', the Div/Mult parameter does not affect the output tempo of this jack.Also, even if Mini PEG is operated with an external clock with a different tempo, the tapped tempo will continue to be output.This feature allowsPing buttonEOF jackThesemi-independentIt becomes possible to use it as a tap tempo submodule of. Tapping the Ping button only changes the EOF jack tempo, not the envelope tempo.

Bus clock

The Clock Bus is a 1:1 clock running on the gate pin of the Eurorack Powerbus.This feature allows the corresponding module to send a clock signal over the power bus, allowing multiple modules to synchronize to this clock. 4ms Mini PEG, DLD, QCD all support sending and receiving clocks via the Clock Bus, while RCD and SCM Plus only support receiving. Modules capable of sending a 8rd party Clock Bus, such as the Malekko Varigate XNUMX+, may also be compatible.

On the back of the Mini PEG there is a jumper for setting the clock to be sent or received via the Clock Bus.

If the jumper is inserted in the 'RECV' position, the clock pulses on the Clock Bus will be the same as if they were patched directly to the jack.PingSent to Jack.If a cable is connected to the Ping jack on the front panel, the Clock Bus signal will be overridden.

If the jumper is inserted in the 'SEND' position, the ping clock before being multiplied/divided is sent via the Clock Bus.For example, tapping a tempo with the Ping button or patching an external clock to the Ping jack will send this tempo 1:1 to the Clock Bus. Changing the Div/Mult amount does not affect the Clock Bus signal. When using the Mini PEG to send clocks, make sure no other modules are set to send clocks on the same Clock Bus.If there are multiple modules that send clocks on the same Clock Bus, unexpected results such as malfunctions and failures may occur.

If you want to disable the use of the Clock Bus, remove the jumper without inserting it.For example, you can store one side of a jumper on only one pin.

System Mode

CycleSystem Mode, accessed by holding the button for 3 seconds, allows you to change various behaviors of Mini PEG.Release the button when the LED on the button flashes to confirm system mode.

System mode can be exited at any stage, and to exitPingbutton orCycleHold the button for 3 seconds. If you exit with the Cycle button, any changes you have made will be applied but not saved and the previously saved values ​​will be restored after powering down the module. If you exit with the Ping button, your changes will be saved.

If you enter System mode with the Cycle button on, the envelope will continue to cycle while in System mode, but you will not be able to adjust any parameters.

Save Clock period and Cycle state
The period of the ping clock and the state of the Cycle button can be saved, and the saved values ​​will be loaded the next time the module is powered on.

If you have external clocks patched to the Ping jacks or are receiving clocks via the Clock Bus, the tempo of those clocks will be saved. If you tap the tempo with the Ping button, this tempo will be saved.In both cases the tempo is saved before the Div/Mult value is applied.

It also stores whether the module is cycled or not.If the Cycle button is illuminated when you enter system mode, Cycle will be on the next time you turn on the module.

System mode has 6 parameters,CycleBy tapping the button, the parameters are switched in order.To change the value of a parameter,PingTap the button.
