| Release Notes | * SunVox Audio Unit (AUv3) can now be used as an effect (filter) inside other DAWs; * new module - Pitch Detector for detecting the pitch of the incoming signal; the frequency and note will be displayed; notes will be sent to the module output; see example "pitch correction (automatic tuning)"; * new module - ADSR envelope generator; see examples adsr, adsr2, adsr3; * new module - Ctl2Note for converting the controller value into a note (input - automation; output - notes); see example ctl2note; * Analog Generator: new waveform "harmonics" allows you to draw the harmonic distribution; but remember, if you turn on all 32 harmonics, then the module's performance will slow down 32 times compared to a pure sine generator; reduced polyphony and LQmono mode will slightly reduce the CPU load; * SpectraVoice: new harmonic types: overtones1+, overtones2+, overtones3+, overtones4+, metal; * LFO: new controller "Frequency scale" (in percents) - use it to slow or accelerate the oscillations; * LFO: new controller "Smooth transitions" - disable it to get hard transitions inside the waveform; * Generator, Kicker, SpectraVoice: increased resolution (accuracy) of Attack and Release controllers; (only if the base version is 1.9.6 or higher in the Project Properties); * Sound2Ctl: new option "Send only changed values"; * MultiSynth: new option "Round the note (X-axis on curve3) to the nearest integer" (remove microtones); * MultiSynth: new option "Round the pitch (Y-axis on curve3) to the closest"; * MultiSynth: new option "Record notes to the scale (curve3)"; see example "dynamic scale"; * MultiSynth: new option "Output note = Output note - Input note + C5" (difference between output and input pitch); * MultiSynth: new option "Output port number = note % number of connected outputs"; (% is the modulo (remainder) operation); see example "drumkit 3 (multisynth)"; * MultiSynth: new option "Output port number = polyphonic channel % number of connected outputs"; * MultiSynth: new curve 3 describing the dependence of the output pitch on the input note; * MetaModule: new options "Receive notes from the keyboard" and "Don't receive notes from the keyboard"; * MetaModule -> User defined controllers: edit buttons (add,delete,move up/down) have been added; * Pitch shifter: incoming notes change the value of controller 02.Pitch; the C5 note corresponds to zero; * Pitch shifter: new controller "Bypass if pitch=0" - play the original signal when the module does not change the pitch; * MetaModule, MultiSynth, Sound2Ctl, Sampler, Analog Generator: options can be accessed in the same way as controllers (see the exact numbers in the options list); * new MIDI IN mode for modules - "never" (never receive MIDI data); * improved popup menus: additional navigation keys (up,down,left,right,space,enter,escape); horizontal scroll if the menu does not fit on the screen; highlight of the current effect; * new pattern effects (column EE): 05 and 06 - pitch bend up/down (one semitone = 100 (256dec)); * new keyboard shortcuts for the timeline: slice, mute, solo, unmute, set restart position, snap to grid (unassigned by default); * new folder "curves" (with curves for MultiSynth, MultiCtl and WaveShaper); * new modules in the instruments/ and effects/ folders; * new examples (SunVox Compo 2020.02 winners): Trackerbound - Alpha Ursae Minoris, Trackerbound - Silentium, manganoid - Lazy Thunder, SawZer - Phantom; * bug fixes. |
