SY-4X

SY-4X Syncussion by Aly James Lab is a versatile drum synthesizer plugin inspired by the iconic Pearl Syncussion SY-1.
It offers a detailed emulation of the original hardware with added features, including four independent modules, advanced oscillator modes, a unique filter design, and enhanced modulation options. The plugin is capable of creating diverse percussive sounds, mono synths, and poly synths, making it ideal for both vintage enthusiasts and modern producers.
:

• Circuit Model: Accurately reproduces the Syncussion design and sound.
• 4 Independent Syncussion modules.
• CMOS based oscillators for authentic tone generation.
• Multi Outputs routing capability.
• Drum Kit or Keyboard Modes.
• Modeled VCF Filter topology, 2-pole "spreading" low-pass filter with extra user control.
• Up to 60 optional pitch scaling rules to choose from.
• Optional Berserk Mode with 2 types of distortion.
• Most parameters respond to automation.
• Settings and preset browser pages.
• Improved VST3 MIDI support.
• Up to X16 Oversampling.

The Syncussion could also be controlled from external CV, it could track more or less over 4 octaves and can be used to play actual notes.
SY-4X brings that to another level. By switching a module from Drum Kit mode to Keyboard Mode, you will now control both voices from your keyboard at the same time.

One of the features is that you can optionally switch to near-perfect pitch tracking between oscillators, but not only that: You can now scale the pitch CV to an actual musical pitch following a defined scaling rule of your choice.

The TUNE slider will now be scaled, as will the incoming CV, to either a 1-step scaling (for example: whole tone) or a full scale. This scaling works in both Drum Kit (nice with Sample and Hold) and Keyboard Modes. In absolute pitch mode, you define the ROOT of the scale; in relative mode, the current played note will be the root.
