Ideas for longer term

Synthesis

  • Oscillator mode with FM & Ringmod

  • Virtual analog filters with non-linearities

  • 2D Wavetable

  • Wavetable oscillator from formula

  • eg: sample="sin(pi * x)" Serum: sin(pi * -x)
  • see: https://s3.amazonaws.com/decembercymatics/Serum_Manual.pdf (chapter 15: Formula Parser)
  • discussion of Serum parser: https://www.kvraudio.com/forum/viewtopic.php?t=425973
  • MIT parser library: http://www.partow.net/programming/exprtk/index.html

  • This suggestion is not to copy Serum, but rather enable custom wavetables to be constructed by Sfizz

  • Granular

  • Physical modelling (waveguide opcodes)

  • Scala tuning support (load Scala file, set root note of scale & mapped A4=Hertz value)

  • see http://www.huygens-fokker.org/scala/scl_format.html

  • default: (Equal Temperament, C, A4_MIDI_note_69=440hz)

  • Analogue tuning of regions, (not Analogue modelling)

  • possibly tune=analogue? Or additional opcode.

Modulation

  • Arpeggiator

  • Random walk LFO

  • see https://www.muffwiggler.com/forum/viewtopic.php?t=10563

  • LFO sync to host tempo

  • LFO header for free running global LFOs

Sample Playback

  • Global memory storage, allow multiple Sfizz instances to use same file pool

  • Slice sample playback, from audio file with markers, useful for beat slicing, or concatenated sample libs. eg:

<region>
sample=mysample.wav
slice=1
- Possibly allow custom map for samples without markers?slice_map=sampleslices.csv

  • Allow sfizz to load samples into RAM, instead of streaming, possibly hint_ram or as per Sforzando ARIA.

  • Load multi-channel samples, and allow selecting stereo/mono channel per region

Effects

  • Standard effect set

  • Signal flow arrangements (cf. dsp_order)

  • Effects per region / voice

Routing

  • Flexible routing : allow regions to be routed to separate sends

  • Multi-channel output

Expressivity

  • Metalanguage to write SFZ more easily, with less repetition. Consider some ideas from CamelAudio Alchemy.
  • edit several properties of an item with indenting syntax
  • load data from CSV files

Intruments

  • Import other existing sample libraries

MIDI Standards

  • MPE
  • MIDI 2.0

Community

  • Sfizz Cloud integration
  • similar to Blender Cloud membership, allow download of sample sets and tutorials
