What's new in 1.1.0

Highlights - Added wavetable playback: - Added wavetable mode to subtractive: - Two wavetable oscillators with variable position (WT pos) and pitch (ratio). - 1>2 FM sets the frequency modulation amount from wavetable oscillator 1 on wavetable oscillator 2. - 1/2 mix sets the balance between the two wavetable oscillators - Added wavetable mini engine to quad engine: - Wavetable oscillator with variable position (WT pos) and pitch (ratio). - Supported wavetable format: - Any audio file type supported by the PolyPulse (such as *.wav). - Cycle length specified at end of filename: cool-wavetable-WT2048.wav - Wavetables are configured from the track settings ([edit]+[track]): - wavetable mode sets the interpolation of the wavetable position: switch (no interpolation) or interpolate (uses more CPU). - The following sequencer parameters can now be modulated: - start - length - chance - seq reset - per pulse: - start - length - chance - interval - offset - octave - reset - note sel - time - rand time - Modulators assigned to sequencer parameters can’t be triggered by all trigger sources. Depending on what parameter is modulated some triggers are locked and set to false in the trigger settings menu. - Sequencer parameter start, length and chance can now be set for each pulse individually by enabling start/len per pulse and/or chance per pulse in track settings. - Improved audio recording workflow: - Added start (track/out) to settings: - directly: recording starts directly. - after trigger: recording starts at the first trigger of the track(s) that are to be recorded. - Added stop (track/out) to settings: - manually: recording is not automatically stopped. - no signal: recording is stopped when no more audio is present. - no signal + no clock: recording is stopped when no more audio is present and the clock is not running.
