Synth1

From the Ichiro Toda webpage:

Synth1 is a software synthesizer for computer music use. It is both VSTi and DX compatible. The current version is freeware.

Functionally it is modelled on the Clavia Nord Lead 2Red Synth ; with the following characteristics:

  • 2 Oscillators, FM modulation, ring modulation,sync,modulation envelope
  • 4 types of filters, distortion
  • 2LFO(synchronized with host)
  • Arpeggiator (synchronized with host)
  • Tempo delay (synchronized with host), stereo chorus/flanger
  • Legato mode, portamento
  • 16 notes polyphony
  • 128 presets
  • Thoroughly optimized for light CPU load using SSE instructions etc. It is quite possible to run 10 simultaneous instances on a Celeron 1.4 GHz system
  • Automation (only in VSTi mode)

As to what is updated exactly is not totally clear to me for I do not read Japanese, but for those who do:

Update: KVR has a partial Japanese-English translation, so here’s what’s new. I will leave the Japanese info below since it looks kinda cool ;-)
