HyperSID is a realtime MIDI synth editor that allows you full control of every sound shaping parameter found on a HyperSID hardware unit. This hardware unit is based on the old C64 synthesizer Chip (SID) and It is a kind of "DIY" project. Real time integration between software and hardware makes HyperSID act like the other VST instruments in your host application. Because its sounds are fully generated by the hardware unit the VSTi Software has a very low CPU usage than the other VST instruments.

Features:

• 3 OSC per key (Monophonic)
• 1 OSC per key (3 Voice polyphonic)
• 4 Waveforms per OSC Tri , Saw ,Noise, Pulse (combinatorial)
• OSC transpose range +36 to -36 Semitone
• OSC cent range -50 to +50 Cent
• OSC ring modulation
• 3 Amp Envelope ADSR
• Multimode analog filter 12dB/Octave HP , LP , BP and (combinatorial)
• 1 LFO Part with sync , retrig and invert capability
• 1 Step LFO Part with sync , retrig and invert capability
• 2 General purpose envelope generator with invert capability
• Individual routing for each modulation source
• 88 Parameter for controlling overall synthesizer (automation recordable)
• Flexible preset manager with save and load function
• Built in 64 categorized Factory preset .
• Clean sound without any Self oscillating in most of the Presets
• Automatic real time synchronization between software and hardware
• Independent MIDI out path from host
• Very low CPU usage
