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
