Signal Processing / Utility

Mono/Poly Osc Sync: CPU: 0.000%(poly) 0.060%(mono)
This module fixes a SynthEdit problem when using Note_On Oscillator Sync in Mono Mode
SynthEdit can cause bad 'Clicks' in mono mode with Note_On Sync
My module ensures that Osc Sync only occurs on 'fresh' notes - overlapping mono notes play smoothly

Pitch Latch: CPU: 0.000%
For use with CK_Osc's using the 'Limit Freq System: B'

Stepper (Decimator): CPU: 0.000% / 0.090%
Converts Voltage signals into 'Stepped' signals. Can be used as a 'decimator' with Audio signals
Can also create 'Glissando' type sounds when applied to Pitch(octave) signals
Steps per Volt: (1..100) Number of steps per 1 volt - set to 12 for 'Note Glissando' when used with Pitch(octave) signals
Mode: (Step, Smooth(bypass)) Smooth mode passes the input to the output without modification

Degrader: CPU Step:0.080% Linear:0.095% Curve:0.130%
Degrades Audio signals by reducing the sampling
Degrade(ratio): (Off, Pass, 2..250) Sets the amount of signal degradation
Mode: (Step, Linear, Curve) Affects the harshness of the degraded sound

Analogue Drift: CPU: 0.100%(typ)
Simulates the small voltage variances of analogue synths. Can be applied to Pitch/Oscillators or filters etc
Drift Depth, Rate(s): Controls the Depth and Rate of Analogue Drift. 0v = Digital (Off)
Update Output Rate: Allows you to control how often the output status updates (affects CPU)

MIDI

Midi All to One:
Combines all Midi channels to one

Midi Low High Note:
Independently Outputs the Lowest and/or the Highest midi note during playing
Low Channel: Specify the output channel of the Lowest note
High Channel: Specify the output channel of the Highest note
Low/High Mode: (New, Dynamic)
New:- only newly played notes update the Low/High outputs
Dynamic:- Lowest/Highest of all 'currently' played notes are output

Midi Note Delay:
Channel(1-16): Only the specified midi channel is processed
Midi Note On/Off messages are delayed and sent to 'Notes out'
All other midi messages (CC, Aft, Bend etc) are sent to 'Other Out'
Delay(ms): time notes are delayed
Multiple: *Specialist Use* if used with multiple sound paths(i.e 'manual unison') each stage can be delayed further to reduce CPU spikes
Note Delay time = Delay * Multiple

Envelopes

Envelope 4: Independent multi-stage envelope with Repeating(looping) and 'One-Shot' function
Envelope 5: 5 stage (6 point)
Envelope 8: 8 stage (9 point)

EnvelopeV2 4: *New* V2 versions now compatible with the 'CK_Envelope_Display' module
EnvelopeV2 5:
EnvelopeV2 8:
**NEW FEATURE** Gate Mode: (Release, Hold)
Release mode is as normal - the Envelope will release when the GATE releases
Hold mode will keep the Envelope in the Sustain or Repeating section even after the GATE is released
This allows a repeating Envelope to keep on modulating Filters etc while the AMP/VCA envelope is Releasing
The envelope will still retrigger as normal on each new GATE/TRIGGER signal

CPU: depends which 'Shape' is being used:- Typical: 0.100% to 0.120% : 'Root' shapes use the highest CPU:- 0.190%
The Shape/Curve is calculated in realtime for highest accuracy

Time Scaler(ratio): Adjusts all stage times proportionately (eg Key/Velocity scaling)

Sustain Stage: (OFF,1,2...) Define which stage is the Sustain(held) stage
Allows envelope 'Release' section to have multiple stages
If both Sustain and Repeat are 'OFF' then the envelope will play through to the end when triggered (One-Shot)

Repeat From Stage: (OFF,Start,1,2...) Define which stage to repeat from when the Sustain stage is reached
This allows you to create a repeating/looping section of the envelope when 'Held'
If Sustain stage is OFF and Repeat From is set, then the envelope will repeat from the End
If Repeat From Stage is 'Start' and Sustain Stage is 'OFF' then the whole envelope will repeat while 'Held'

Retrigger/Repeat Mode: (ReStart, PickUp)
When the envelope Triggers or Repeats these modes define whether the envelope will use the current level or use the new envelope stage level directly

Time 1-8: Set the time(s,ms) of each stage. The Time is 'latched' as each stage starts

Time Mode: (s, ms) Stage times can be set as Seconds(s) or (ms)

Start Level: Sets the initial level when the envelope is triggered

Level 1-8: Sets the final level of each stage
Note: The last stage level is the end level of the envelope - this is normally set to zero for 'Amp' use

Shape 1-8: Allows you to set the shape/curve of each stage independently, from a choice of:-
Linear, Exp, Inv.Exp, Exp2, Inv.Exp2, Root, Inv.Root, Exp.Root, Inv.Exp.Root, S_Crv, Inv.S_Crv, S_Crv2, Inv.S_Crv2, Step



Env Osc 5: Oscillator based 5 point envelope generator
Env Osc 9: 9 point envelope
*NEW* now compatible with the 'CK_Envelope_Display' module
CPU: Step:0.095%/0.185% Linear:0.135%/0.220% Exp:0.140%/0.220% Inv.Exp:0.165%/0.240% Curve:0.200%/0.280%
Define envelope levels at fixed points along the wave/duty cycle
Can be used as a user defined Modulator/Waveshaper or waveform generator using Curve mode

Pitch: (Octave, Khz, Hz) Sets the Frequency of the Envelope

Volume: Overall output level

Level 1-9: Sets the envelope level at each point

Env Shape: (Linear, Exp, Inv.Exp, Curve, Step) Sets the envelope shape/curve for all points
The Shape/Curve is calculated in realtime for highest accuracy

Envelope Display ** NEW GDI+ Graphics **

GDI+ graphics
**NEW** GDI+ graphics providing Alpha (blending), Antialiasing (smoothing) and Colour Gradients (shading)

 The Envelope Display module can display up to 8 different Envelopes and switches automatically to display the one that is being 'Edited'
The user can also 'call-up' the other envelopes without having to edit them
It has a dynamic window and features Auto display sizing if the envelope levels go outside the standard 0-10v range
The display supports Transparent backgrounds(-1) with Solid or Line(1,2,3 thickness) envelope display
You can specify RGB(0-255) colours for Background, Envelope, Repeat/Release zone and Text
It will highlight the 'Release' section if 'Sustain' is used - Or the 'Repeat' section if set
There is also an option to display the 'Total Time'

You can now give a 'Name' to each envelope which will be displayed on the window

CK_Envelope_Display is compatible with EnvelopeV2, Env_Osc, Flexi_Osc and GUI_Envelope(Pack 8) modules

*NOTE* Due to restrictions within SynthEdit the Flexi_Osc and Env_Osc modules will only update the Envelope_Display when 'playing'
(otherwise all polyphonic voices for Flexi_Osc and Env_Osc modules would have to be 'awake' 100% of the time - which would not be good for CPU)

Oscillators

 For information on Common controls and Technical information see:- Pack6/7_Osc_Tech

All Audio Examples are taken directly from the Oscillator output (standard versions)
 (Simple Modulation control is from a 'CK_Envelope' or LFO)


Standard Oscillator

Standard Osc: CPU 0.120% / 0.240%
Standard Osc_2k:
Standard single wave/voice oscillator
Pitch Adjust(offset): Allows the pitch to be offset with no extra CPU
*Note: if you normally combine Pitch and Offset signals by linking both to the same input SE adds a 'hidden Adder' module
If either signal modulates then it will use extra CPU without you seeing/knowing it


Unison Oscillators

Unison Osc: Up to 7 Voices(waves) in Unison(detuned) combined to one output
Unison Osc_2k:
CPU: Depends on the number of Voices playing:- (standard version) x1:0.120% x3:0.205% x5:0.280% x7:0.360%
Detuning is always balanced around the Pitch whatever the number of voices playing
The output level is balanced depending on the number of voices playing
Independent Waveform and Harmonics for each Voice
Unison (1-7): Specify how many voices to play in unison
Detune: Sets the amount of detuning between each voice
Detune Stretch: Changes the detuning from Linear(1.0) to an increasingly Non-Linear system

Audio Example:- 3 Saw Voice unison
Audio Example:- 5 Saw Voice unison
Audio Example:- 7 Saw Voice unison

Unison Osc Multi: Up to 7 Voices(waves) in Unison(detuned) with independent outputs
Unison Osc Multi_2k:
CPU: Depends on the number of Voices playing:- (standard version) x1:0.120% x3:0.190% x5:0.260% x7:0.340%
Each Voice is output at full level
Other controls function as in Unison_Osc module above

*Note: Unison Oscillators only respond to 'Block-Rate' Pitch Mod (which is fine for most LFO/Envelope/Pitch Bending use)
 If Realtime Pitch Mod is essential you can use a 'Multi_Osc' instead:-
Multi_Osc allows you to set up your own 'customised unison' system with User-defined voice detunings/Levels etc
An Example .SE1 prefab is provided in Pack7 to show how to set this up


Flexi Oscillator

Compatible with the 'CK_Envelope_Display' module

Flexi_Osc:
Flexi_Osc_2k:
Dual voice osc, WaveB pitch offsetting, internal 9 point Osc_Envelope
18 Oscillator Modes, 2 Envelope shapes (Linear, Curve)

Wave B/Env Offset: You can select the Pitch Offset for Wave B/Envelope relative to WaveA
Offset Choices range from +3/-4 Octaves, +8/-16 Harmonics, 0/+11 Twelfths or Timebase
Both waves are 'Phase Locked' i.e the phase of Wave B/Env is directly related to WaveA
There is no drifting of phase no matter how much pitch modulation occurs

Spectrum Oscillators

Spectrum_Osc32: CPU: 0.160% / 0.240%
Spectrum_Osc64: CPU: 0.160% / 0.240%
This is a 'Hybrid' module that creates wavetables(1024 samples) from user-defined Harmonic levels
This allows you to create all the 'fixed spectrum' tones of a 'Spectral' oscillator but uses minimal CPU for playback
The downside is that the harmonics cannot be modulated in realtime

Master Volumes Scaling: Adjusts all the harmonic levels
Acts like a 'Volume control' for the wavetables - so is not realtime modulatable

Volume 1-64: Sets the level of each Harmonic

Volume Mode: (Linear, Analogue)

Balance Levels?: (On,Off) When 'ON' all the harmonic levels are 'unit' balanced when the waveform is generated
This helps keep the overall waveform level under control

Edit Mode: (On/Off) When 'ON' the wavetables are generated if the levels change, at the 'Edit Refresh Rate'

Edit Refresh Rate: (1, 3, 5, 10, 20, 40 Hz) Limits how often the wavetables are generated when 'Edit Mode = ON'
Generating the wavetables consumes a lot of CPU(*) - adjust this to suit your PC or use the 'Generate Waveform (button)'

Generate Waveform (button): When 'Edit Mode = OFF' this input allows the User to generate the waveform 'On Demand'
This is useful if the 'Edit Mode = ON' consumes too much system CPU

(*)Note: This module has tested fine on my Pentium4 1.5Ghz PC
It may operate on less powerful PC systems, but i cannot be 100% sure

Spectral(V2) Oscillators

Spectral_OscV2_8: CPU 0.550% / 0.820%
Spectral_OscV2_16: CPU 1.000% / 1.260%
Spectral_OscV2_24: CPU: 1.480% / 1.750%
Spectral_OscV2_32: CPU: 1.960% / 2.220%
Audio Oscillator allowing Realtime Spectral (harmonic) Modulation
Active Harmonics: Limits the number of harmonics in the waveform - can be used as a simple filter by removing high harmonics
Sound Quality: Normal/High

*Note: existing holders of the original 'Spectral Osc' modules in CK_Packs(1-5) can upgrade to these new versions at no cost
