Ichiro Toda Synth1

Ichiro Toda has released version 1.11 of Synth1, a free VST synthesizer instrument for Windows.

Changes in Synth1 v1.11

  • Sound Engine:
    • The sub oscillator was added:
      • The same pitch as oscillator1 or one octave under can be selected.
      • When OSC1 is eight multiple unison, the sub-oscillator becomes similar, too.
      • FM modulation also influences the sub-oscillator as well as OSC1.
      • The sub-oscillator doesn’t influence the AM modulation.
      • When the amount of the sub-oscillator is raised, the entire volume is automatically adjusted not to grow.
      • The wave pulse of the sub-oscillator always becomes a square wave regardless of a pulse width parameter.
    • The saw wave was changed from rising type to the descent type:
      • To operate the sub-oscillator effectively, it changed.
      • The amplitude value by 0 phases changed from 0 to +1.
    • The accuracy of the envelope of Amplifier has been improved.
    • The limiter algorithm of Filter is changed, and the noise has been improved only a little.
    • The performance of OSC1 at eight unisons has been improved a little.
  • System requirements:
    • It did not operate in CPU that did not support SSE2:
      • It seems to cause the expansion of the source code when keeping supporting it any further. To our regret, it was assumed operation off the subject.
      • The error message is displayed in the upper part of the panel when operating with CPU that doesn’t correspond, and the sound is not generated.
  • Small improvement and change of GUI:
    • A part of objection of the parameter name was corrected.
    • The patch selection window etc. were shut with the escape key.
  • Bug Fixes:
    • Problem of operation of sustaining pedal.
    • Problem that old FM setting value remained at voice trigger.
    • Problem that loudness at unison has changed in old version.
    • Problem that gain knob of Amplifier did not occasionally work.
    • Problem that patch change with program change spin button was not made good after it writes it in another bank.
    • Problem with thing that Synth1 window flickers according to environment.
    • Problem that position where parameter selection window etc. are displayed does clip to primary monitor in multi-monitor environment.

Synth1 is available to download as a freeware VST instrument plug-in for Windows PC.
