Hypersynth updates SIDizer to v1.3

Hypersynth SIDizer

HyperSynth has updated the SIDizer SID chip emulation synthesizer instrument to version 1.3.

Using circuit modeling technology nearly all unique features of two versions (6581-8580) of SID chip among their famous flaws are accurately modeled. This emulation focuses on simulating nonlinear character of SID filter and mimicking special 6581 distortion that mainly influence the alternation of filtered signal in a real SID chip.

Changes in SIDizer v1.3

  • Added new skin + several GUI enhancements.
  • Added 6 new mod sources: “Note number, Aftertouch, MIDI Breath, MIDI Foot, MIDI Expression, Constant”.
  • Added 4 new mod destinations: “Main Volume, Matrix 1-3 Depth”.
  • Added option to set sound engine quality based on C64 hardware or host sample-rate.
  • Added zero value for Pitch Wheel range.
  • Added MIDI learn and default CC assignment for most of the parameters.
  • Now SIDizer responds to MIDI “program change” and “all notes off” messages.
  • Now in mod matrix “LFO1 noise” and “LFO2 noise” are renamed to “Random Unipolar” and “Random Bipolar” and their functions are updated to match the corresponded name.
  • Fixed Pitch wheel asymmetric problem when it was used as mod source.
  • Fixed issue in modulating filter and oscillators amplitudes.
  • Fixed minor readout issues.
  • Updated documentation: (Added MIDI Implementation Chart , CC tables and etc).

SIDizer for Windows (VST) is available to purchase for $49 USD.

Not even close to the real thing. Reverb and delay?? C’mon.


Not close? http://www.hypersynth.com/sidizer_comparison.html
You don’t *have* to use the onboard effects.


If sound properties could be represented by static snapshot of waveform then every wavetable synth could sound like the instrument from which the sample was taken. You know that’s not the case. It’s much more important how sound changes in time domain with all it’s fluctuations of harmonics and pitch, and nonlinear shape of dynamic curve, both of which can’t be seen in these tiny screenshots. Much simpler: did you try HyperSID? If you didn’t please give it a try and then tell me with straight face that it resembles classic C64 sound. My heart was broken when I heard… Read more »


I guess it’s how you define “close to the real thing”. For me, SIDizer is close enough. I like its sound.
I don’t have a history with C64 though. When in my gaming years I picked the MSX over the C64.

Have you tried Plogue’s Chipsounds? If so, how does that compare in your opinion?


I have to disagree…..
Chipsounds and quadrasid don’t recreate the analog filtering from the original commodore chips.
I’ve played enough with my commodore computer in back in the 80s to know how it sounds.


Chipsounds sounds miles better than HyperSID, but I’ve found it’s GUI too complicated and unintuitive. Quadrasid is my favorite, without a doubt.


HyperSID and SIDizer are two different products. HyperSID is actually a hardware synth with a real SID chip inside and SIDizer is a software emulation. I’m sure you mean SIDizer regarding the topic.


This is the best software emulation !!!
Quadrasid and 389111bytes are my other favorites emulation but sidizer has the best filter/distorsion ever.
The arpeggio is also great.
The only thing I don’t like in sidizer is the challenge/response protection scheme.
Reverb and Delay ???? always off and that’s ok
