Ramp Generator - A multi-purpose block based on one half of the Make Noise 'Maths' function generator eurorack module.

The block can be used as a ramp signal generator, several types of envelope (with or without sustain), a slew processor, a clock generator, a versatile oscillator, a filter, a voltage processor, a pitch-glide effect with separate control of ‘up’ and ‘down’ speeds, a waveshaper or anything in-between.

The block has 3 input ports, RESET, TRIGGER and SLEW for for driving and triggering the ramps:

RESET = A positive zero crossing at this input causes the ramp cycle to restart. The ramp will restart from its current level, rise at the rate set by the 'RISE' control until the level reaches maximum (1) and then fall back to 0 at the rate set by the 'FALL' control, completing the RISE-FALL cycle. A gate signal at this port turns the block into an AD (attack-decay) envelope.
TRIGGER = Positive values at this port will trigger the ramp to rise all the way up until it reaches the original triggering value. It will rise at the rate set by 'RISE' and fall at the rate set by 'FALL' but will always continue to ramp up or down until the trigger value has been reached. This port is similar to Reset port except the input values control the destination level of the ramps. This port can be thought of as kind of a cross between the Reset port and the Slew port. A gate signal at this port turns the block into a velocity sensitive AHD (attack-hold-decay) envelope.
SLEW = Signals at this input will be ramped smoothly between values. The 'RISE' and 'FALL' controls set the rise and fall time of the ramps. This port can be used with pitch signals to give a pitch glide effect or to smooth modulation signals.

Randomizer - Incoming gate signals generate random values.
Segment - A single segment of a multi-breakpoint envelope. Daisy-chain several segments by connecting OUT to IN and RESET to RESET. When a gate signal is received at the RESET port the current value at the IN port is used to determine the starting level of the segment. The output will then fall or rise until it reaches the value of the LEVEL control for the duration set by the TIME control.
Synced Segment - A single segment of a multi-breakpoint envelope. The duration of the segment is synced to the host tempo.

Sequencers

A sequencers in the Tangle Pack will generally consist of 3 blocks / elements:

A ramp block that outputs a ramp signal slowly going from 0 to 1 that drives the playback position of the sequence. This signal is called the 'position' signal.
One or more 'position modifying' blocks that modify this position signal, adding rolls to certain steps in the sequence, repeating certain steps, skipping steps etc.
A 'Sequencer' block whose playback position is driven by this position signal and that outputs pitch values or gate signals to playback the sound generating element of your rack. READ MORE

Value Sequencer - An 8 step level sequencer.
Seq Segment - A single segment of a sequencer. Daisy-chain several segments by connecting the 'NEXT' port to the next segment's 'RESET' port.
There are 16 playback modes:

REPEAT= Repeat steps

Euclidean Sequencer - The number of gates, set by the GATES knob, will be distributed equally across the number of steps, set by the STEPS knob.
Note Recorder - Records a sequence of MIDI notes. Notes can be recorded and played back simultaneously at different positions in the sequence, and the RECORD POSITION, PITCH and GATE ports can be used to produce complex note sequences by connecting LFOs or modulations sources to these ports. The maximum size for the sequence can be set on the snapshots panel.

Sequencers - Position Modifiers

The sequencer blocks in the pack are all driven by a ‘position’ signal that needs to be connected to the block's POSITION port. The position signal is just a signal that ramps up from 0 to 1 slowly in a looping fashion. The position signal simply represents the current position of the sequence (the RAMPS block can be used to generate a suitable position signal, although really any audio signal can be used, for example the output of an oscillator or an LFO). The following position modifying blocks are designed to modify this position signal in order to modify the playback of the sequence, repeating or skipping section etc. If you connect a 'Modulation Scope' block before and after the position modifying blocks you can visualize how the signal is being modified in order to alter the playback of the sequence.

Conditional - Applies a condition for each step of the incoming position signal, step will only play if that condition is met.
Modes:

---- = Step always plays
OFF = Step never plays
1:2 = Step plays on the first bar every 2 bars
2:2 = Step plays on the second bar every 2 bars
1:3 = Step plays on the first bar every 3 bars
etc
FILL = Step plays when the FILL port is positive
!FIL = Step plays when the FILL port is not positive
5% to 95% = Probability the step will play

Fast - The incoming position signal is modified by speeding up the ramp of each step. Setting the speed of a step to 'SKIP' will result in that step being skipped.
Repeat - The incoming position signal is modified by repeating each step. Setting the repeat count to 'SKIP' will result in that step being skipped.
Roll - The incoming position signal is modified by adding repeats for each step.
Slow - The incoming position signal is modified by slowing down each step according to the values. Setting the speed of a step to 'SKIP' will result in that step being skipped.
Time Shift - The incoming position signal is modified by shifting the position of each step forward or backward in time.
Swing - Adds a swing feel to the incoming position signal by slightly bending every other step.

Sequencers - Tools

Counter - Counts up to 32 steps. The position of the counter is incremented by gates received by the GATE input. The block outputs POSITION signals between 0 and 1 that represents the current step number.
The 'STEP MODE' control sets the mode and direction of movement of the sequencer. The following modes are available:

FWD (forward) = The sequence plays forwards.
REV (reverse) = The sequence is reversed.
FWD-REV (forward then reverse) = The sequence plays forwards and then backwards, for example: 1,2,3,4,4,3,2,1,1,2,3,4 etc.
TRI (triangle) = Same as FWD-REV but adds an extra step at the end so that the first and last steps aren't repeated, for example: 1,2,3,4,5,4,3,2,1,2,3,4,5 etc.
PATT 1 (pattern 1) = Plays back the sequence using a pattern.
PATT 2 (pattern 2) = Plays back the sequence using a different pattern.
RAND (random) = Plays back the steps randomly.
GLITCH = Same as FWD except every so often plays a random step.

Position Divider - Splits up a position signal into up to 8 separate position signals.
Position Range - Ranges the incoming position signal between START and END points.
Position Shift - Offsets the position input by a certain number of steps.
Position Speed - Speeds up or slows down the position signal by multiplying it by fixed values of 6th and 8th divisions.
Position Splitter - Splits up a position signal into up to 4 separate position signals. Click on the LEDs to mute the outputs. You can also use these LED buttons to select how many steps are in the sequence if the only the POS output port is connected.
The are 5 different modes for splitting the signal up in different ways:

FAST = The position signal is split into parts of even length and then each part is multiplied by the MULT knobs.
REPEAT = The position signal is split into parts of varying length (depending on the MULT knobs) and then each part is multiplied by the MULT knobs, therefore repeating each of the sections yet keeping the speed of each section the same.
SPLIT = The position signal is split into parts of varying length (depending on the MULT knobs).
FIX = Same as REPEAT except the the overall length of the sequence is fixed.
STRETCH = Same as SPLIT except the the overall length of the sequence is fixed.

Polyphonic Blocks

The polyphonic blocks feature special polyphonic ports denoted by a light grey circle around the edge of the port.

Polyphonic output ports can be connected to monophonic input ports and vice versa. There are also various utility 'Voice' blocks to convert polyphonic output signals to individual monophonic signals for each voice or to modulate the individual voices etc.

Monophonic output ports can be connected to polyphonic input ports, you can for example connect a monophonic signal from the regular (non-polyphonic) Mini Oscillator block to the polyphonic 'A/B' modulation input ports of the Polyphonic Filter block to modulate all 5 voices simultaneously.

All polyphonic blocks are set to 5 voice polyphony by default (if required this can be changed for each block using 'Voices' setting in the inspector when the blocks are loaded in ensemble mode).

Most of the polyphonic oscillator blocks have an AMP (VCA - voltage controlled amplifier) port that controls the volume of the voices. This port also switches off processing of the voices when the value is zero, therefore you can save some CPU power by using these ports (by connecting an envelope or gate signal to it).

For convenience the A/B modulation sliders on all of the polyphonic versions of the blocks are hard-wired to 2 internal voice spreader circuits, which can be used to apply some spreading to the control's value across the 5 internal voices. Modulation Bus A is wired to a uni-directional spreader and Modulation Bus B is wired to a bi-directional spreader.

For example, to create a detuned 'unison' sound using the 'Tangle Oscillator (Polyphonic)' block first connect the block to Reaktor's output and set the shape to SAWTOOTH, with nothing connected to the B modulation bus port (so that the bi-directional spreader is used instead), you can increase to the B modulation amount slider (click on the 'B' button to show it) to begin spreading out the tuning of the 5 voices for a thick, 'unison' type sound. As you increase the modulation slider you will see the 5 modulation indicator triangles spread out around the control indicating the fine tune position of the 5 individual voices.

The modulation indicators around the knobs of the blocks will show the current modulation values for each voice. Other parts of the user interface, for example sample waveform and filter displays will only show the display for the most recently played voice. Sometimes these displays can get out of sync with incoming MIDI notes, if this happens just save and re-open the rack, and the displays will be correctly synchronized with the incoming MIDI notes.

Ramp Generator (Polyphonic) - A multi purpose block that can be used as a ramp signal generator, oscillator, slew processor, envelope, clock source or waveshaper. The block has 3 input ports for for driving and triggering the ramps:

Reset: A positive zero crossing at this input causes the ramp cycle to restart. The ramp will restart from its current level, rise at the rate set by the 'RISE' control until the level reaches maximum (1) and then fall back to 0 at the rate set by the 'FALL' control, completing the RISE-FALL cycle. A gate signal at this port turns the block into an AD (attack-decay) envelope.
Trigger: Positive values at this port will trigger the ramp to rise all the way up until it reaches the original triggering value. It will rise at the rate set by 'RISE' and fall at the rate set by 'FALL' but will always continue to ramp up or down until the trigger value has been reached. This port is similar to Reset port except the input values control the destination level of the ramps. This port can be thought of as kind of a cross between the Reset port and the Slew port. A gate signal at this port turns the block into a velocity sensitive AHD (attack-hold-decay) envelope.
Slew: Signals at this input will be ramped smoothly between values. The 'RISE' and 'FALL' controls set the rise and fall time of the ramps. This port can be used with pitch signals to give a pitch glide effect or to smooth modulation signals.

Randomizer (CR Polyphonic) - Incoming gate signals generate random values. This version runs internally using a slower 'control rate' clock rather than 'sample rate' clock, to save CPU.
Randomizer (Polyphonic) - Incoming gate signals generate random values.
Segment (Polyphonic) - A single segment of a multi-breakpoint envelope. Daisy-chain several segments by connecting OUT to IN and RESET to RESET. When a gate signal is received at the RESET port the current value at the IN port is used to determine the starting level of the segment. The output will then fall or rise until it reaches the value of the LEVEL control for the duration set by the TIME control.

Polyphonic Sequencers - Position Modifiers

The sequencer blocks in the pack are all driven by a ‘position’ signal that needs to be connected to their POSITION port. The position signal is just a signal that ramps up from 0 to 1 slowly in a looping fashion. The position signal simply represents the current position of the sequence (the RAMPS block can be used to generate a suitable position signal, although really any audio signal can be used, for example the output of an oscillator or an LFO). The following position modifying blocks are designed to modify this position signal in order to modify the playback of the sequence, repeating or skipping section etc. If you connect a Modulation Scope block before and after the position modifying blocks you can see visually how the signal is being modified in order to alter the playback of the sequence.

Conditional - Applies a condition for each step of the incoming position signal, step will only play if that condition is met.
Modes:

---- = Step always plays
OFF = Step never plays
1:2 = Step plays on the first bar every 2 bars
2:2 = Step plays on the second bar every 2 bars
1:3 = Step plays on the first bar every 3 bars
etc
FILL = Step plays when the FILL port is positive
!FIL = Step plays when the FILL port is not positive
5% to 95% = Probability the step will play

Fast - The incoming position signal is modified by speeding up each step according to the values. Setting the repeat count to 'SKIP' will result in that step being skipped.
Repeat - The incoming position signal is modified by repeating each step. Setting the repeat count to 'SKIP' will result in that step being skipped.
Roll - The incoming position signal is modified by adding repeats for each step.
Slow - The incoming position signal is modified by slowing down each step according to the values. Setting the repeat count to 'SKIP' will result in that step being skipped.
Time Shift - The incoming position signal is modified by shifting the position of each step forward or backward in time.
Swing - Adds a swing feel to the incoming position signal.

Polyphonic Sequencers - Tools

Counter - Counts up to 32 steps. The position of the counter is incremented by gates received by the GATE input. The block outputs POSITION signals between 0 and 1 that represents the current step number.
The 'STEP MODE' control sets the mode and direction of movement of the sequencer. The following modes are available:

FWD (forward) = The sequence plays forwards.
REV (reverse) = The sequence is reversed.
FWD-REV (forward then reverse) = The sequence plays forwards and then backwards, for example: 1,2,3,4,4,3,2,1,1,2,3,4 etc.
TRI (triangle) = Same as FWD-REV but adds an extra step at the end so that the first and last steps aren't repeated, for example: 1,2,3,4,5,4,3,2,1,2,3,4,5 etc.
PATT 1 (pattern 1) = Plays back the sequence using a pattern.
PATT 2 (pattern 2) = Plays back the sequence using a different pattern.
RAND (random) = Plays back the steps randomly.
GLITCH = Same as FWD except every so often plays a random step.

Position Range - Ranges the incoming position signal between START and END points.
Position Shift - Offsets the position input by a certain number of steps.
Position Speed - Speeds up or slows down the position signal by multiplying it by fixed values of 6th and 8th divisions.

The are 5 different modes for splitting the signal up in different ways:

FAST = The position signal is split into parts of even length and then each part is multiplied by the MULT knobs.
REPEAT = The position signal is split into parts of varying length (depending on the MULT knobs) and then each part is multiplied by the MULT knobs, therefore repeating each of the sections yet keeping the speed of each section the same.
SPLIT = The position signal is split into parts of varying length (depending on the MULT knobs).
FIX = Same as REPEAT except the the overall length of the sequence is fixed.
STRETCH = Same as SPLIT except the the overall length of the sequence is fixed.

Ramps - 3 ramps which can be used to drive sequencers, in a single block.
Single Ramp - A single ramp oscillator with 'One-shot' and 'Shape' controls.

Polyphonic Utilities

A suite of polyphonic utilities and 'Nano' utilities.

The versions of the blocks with "CR" in their name run at the slower 'Control Rate' internal clock rather than at the 'Audio Rate' clock, you can use these blocks in combination with the polyphonic modulation blocks rather than the regular audio rate versions to save CPU in larger polyphonic racks. You can set the control rate frequency using the 'Control Rate' sub-menu in Reaktor's 'Settings' menu (default is 400Hz, you can change it to 1600 for better timing performance of the polyphonic modulators and sequencers with very little increase in CPU usage). Note: as the CR versions of the blocks run internally at the slower control rate clock you can not pass audio signals through these blocks, they are designed for modulation signals like LFOs etc.

The group of blocks starting with "Voice" can be used to modulate, spread, route or mute the individual polyphonic voices.

TRI (triangle) = Same as FWD-REV but adds an extra step at the end so that the first and last steps aren't repeated, for example: 1,2,3,4,5,4,3,2,1,2,3,4,5 etc.
PATT 1 (pattern 1) = Plays back the sequence using a pattern.
PATT 2 (pattern 2) = Plays back the sequence using a different pattern.
RAND (random) = Plays back the steps randomly.
GLITCH = Same as FWD except every so often plays a random step.
