VST Core Functionality

• Layers (was called groups) - A drop down to layer multiple node designs
  Will allow you to switch to another layer allowing users to stack their designs and not have them all in 1 page (but both will be possible)
  
  

• 1 layer (dimension) presets (patches that only use 1 layer) can be loaded into any layer at any time in any patch (look into loading multi layer with other multi layer patches, shouldn't be much different, might need to warn users, this could be a major rise in CPU/GPU use and if not careful lead to a lock-up or crash)
  
  

• Module Clusters (essentially layer merge)
  * Need to think about this more as it crosses over into patch loading and merging territory which would actually allow users to do the same thing. Just they would need to save these patches / layers into a folder and called that folder my clusters or something. Do they need hand holding? (the UX/ui in me says "always assume yes", the programme in me says, "they are intelligent people, but there will be some..").
  
  

  • Define a few commonly used for default selection

  • Allow user defined group clusters to be saved
    (while creating a patch a user can copy and paste the modules they want into another group and save that group as a Cluster for use at any time in the future).

  • Users can then delete layer.
    (Same as a patch just save to a directory called clusters or groups)
    
    

• Presets will be json based, to look into architecture per preset or collection for sample storage
  
  

• Lines go under modules
  
  

• Inputs stack on left input hook/connection
  
  

• Outputs stack on right input hook/connection

Modules

• hooks left (inputs), right (outputs), top centre & bottom centre (utility, LFO etc)

• lower user definable infinite module matrix

  • any input can be assigned none, or any amount of times to anything
    (control is from the module input not inside this, double manipulation of input is not required)

  • module matrix is infinite (100 rows should be more than enough) scrollable area user adds as many as they want

Modules

I/O (Input/Output)

• Midi in

  • Velocity

  • Pressure

  • Pitch Wheel

  • Mod Wheel

  • CC

• Midi out

• Audio Out

Midi / Note modification

See other document on this, pick most used/desired, too many for v1...

• Key Range Mapper

• ARP classic

• Midi (.mid file) ARP

• Note chance

• Chord matrix (EG: on C2 press, add E2 & G2, for any key C0 to C8 can be defined)

• Snap to designated keys only in octave range (auto replicates to all octaves)

Sound Generators

• OSC (Classic Sine, Triangle & Square)

  • Maybe add time morph controls to go glide from 1 to maybe 10 user adjusted shapes (look into way to get ADSR (SR) to trigger a 4 user defined shape mode.

• OSC (Wave Table)

• Multi Sample (per key) *not fussed on this

• OSC (User MSEG / ENV Designer)
  Possible morph between 1 to 10 designed shapes over a user defined time (v2?)

• Sampler (kontakt style)

  • 1 sample can be assigned to any and all keys or 1 to a range

  • options on each sample for start, end, loop start, loop end

  • settings to be easily made to be copied over to all other sample or a select few or the 1

• Granulator
  NOTE: Do not offer modulation of start, end etc, this can be done by modules linked to this module (this is not a classic synth vst)

  • 1 sample can be assigned to any and all keys or 1 to a range

  • start

  • end

  • grain size (play length from creation point)

  • grain count

  • grain start overshoot random (keep within start and end)

  • grain end undershoot random (keep within start and end)

OSC Processors (modifiers)

• Additive (add, stack/compound, merge in 1 to in 2 %, algo1, algo2, etc)

• Subtractive (math subtract, check out other algorithms out there)

• Phase shift

• Invert

• Frequency Splitter (cut off)

  • Dynamic single (flip upper / lower cut mode) to up to 3 outputs (lower, mid, upper)

  • 2 band mode

  • 3 band mode

• Envelopes

  • HADSR

  • ADSR

  • MSEG which can be enabled to be (SR concept from concept drawing)

  • etc

Utility

• Link module (become any existing module wire without mess)

• Volume/Gain/Amplitude module

Modulators / Sound Design

All LFO's will have: play once, repeat, sync to DAW infinite loop, sync to DAW one shot, retrigger, poly.

NOTE: Beat / DAW synced LFO’s will all link to 1 hidden bit of code which processes this signal (CPU optimiser)

• LFO (classic)

• LFO (Wave Table)

• LFO (MSEG, User shape defined)

Filters

The usual stuff (code and algorithms already all over github etc)

Audio signal processors

• Freq cut (2 & 3 band)

  • Sharp cut and Blend crossover cut (user control?)

• Mono maker

  • 1 band (lower/upper toggle), 2 and 3 band (blend control v2)

Effects

More after v1, just the common stuff for now…
To look into: effects on polyphony and their application per a note poly-phonically.

• Distortion

• Bit Destroyer

• Delay

• Reverb

• Stereo Widener (maybe v2)
