Sprike

Virtual Analog Synthesizer

Sprike is an extended version of Tunefish4, originally created by Brain Control (https://github.com/paynebc/tunefish), with modifications and enhancements added by Cognitone. While the actual sound synthesis was not changed (in fact, you can import your existing Tunefish4 presets), Sprike features a differently organized preset storage, 4 additional MOD sources, an on-screen keyboard, a level meter, tempo-controlled delay units, and a more complete MIDI implementation with bank plus program selection, in order to integrate more transparently with MIDI-controlled environments and conventions.

We chose a new name and ID for Sprike, so it can coexist with Tunefish installations out there (versions 4, 3 and 2). In addition, we changed the look and feel, so users won't confuse it with Tunefish4.

IMPORTANT: If you want to fork this project, please change the plugin name, bundle identifiers and manufacturer ID, to make sure it won't clash with installations already deployed out there! That is, replace all traces of Cognitone and Sprike. Thanks. If you want to report bugs and/or suggest enhancements, feel free to contact us at any time.

  • Fixed a generator modulation overflow issue
  • Copy/Paste/Restore preset buttons did not work as expected

Sounds

Preset Storage

In order to comply with operating system conventions, and to separate user-created presets from factory presets, all presets are now stored in the following folders:

Mac

/Library/Audio/Presets/Cognitone/Sprike (factory)
~/Library/Audio/Presets/Cognitone/Sprike (user)

Windows 10

C:\ProgramData\Cognitone\Sprike (factory)
C:\Users\<Username>\AppData\Local\Cognitone\Sprike (user)

If you edit and save a factory preset, it will not be overwritten, but stored in your user folder instead. This protects factory presets from accidential modification. For how to import tf4 presets, please read the README file in the factory presets folder.

How To Compile

Get Juce version 4 or later and use Projucer to create project exporters for Windows or Mac. Please refer to the original Tunefish4 project for instructions on how to compile for Linux. Possibly Projucer will take care of that already.

Download

This repository includes source code only. You can download ready-to-use compiled plug-ins with installers for Windows and Mac (VST, VST3 and AudioUnits) from the Cognitone site: http://www.cognitone.com/get/sprike.
