Synthcore2 Bundle (Max7)

$5.00

This bundles includes: the Synthcore2 library, with over a hundred functions written in Cycling74 gen~ codebox for audio; two complete synths built with the library that implement the audio path entirely in gen~; a demo patch illustrating usage of the main library functions; data files; and a suite of demo patches with graphical designs of the same gen~ and MAX patches.

For free downloadable demos, please see the compiled versions forWin32,Win64, andMacOS X.

The Library

>6 months in the making and the first of its kind, the Synthcore library is designed for performance, ease of use, and flexibility. Multiple demos illustrate how to include and implement the functions.

DECLARATIONSBuffers and constants.

The benefit of codebox implementations is that the functions can be disabled when not in use via conditional clauses like this:

   Param oscillator_select, pitch(60);
   if (oscillator_select == 1){
      sawdown(pitch);
   } else {
     sawup(pitch);
   }

All the library functions have descriptions of values passed in and out, with descriptions of ranges.

Additional Demo Patches

Additional patches included in this download illustrate the main functions with graphical objects instead of code, and include patches for transforming Synthcore into a fully polyphonic instrument. Thre patches are fully documented on this site. for more information, please see:

The EPTR-antialiased square and saw oscillator implementations are now part of Max7's core objects. The library includes codebox implementations, and the quality is illustrated here.

EPTR-antialiased square wave. The gen~ codebox implementation is included.

Synthcore 2 Patch and Source Code

Synthcore 2 is one of the most powerful analog emulation synthesizers ever made, based on features from the OSCAR and Waldorf Q (both of which, as you may know, were discontinued because they were too expensive to build in hardware). The monophonic version is now available for free download in Windows 32/64, Mac OS X, and open-source Cycling'74 Max 7 code.

Main Features and Architecture

  • 3 oscillators, with feedback, FM, four kinds of sync, phase control, ring modulation, and dual output mixing; 61 morphing waveforms, including: pulse, saw, and triangle oscillators with newest EPTR anti-aliasing technology; Karplus physical modeling; multiple filtered noise options; 48 cross-sampled waveset oscillators; and sub oscillator.
  • 2 comb filters, both with pitch tracking.
  • 2 5-d serial/parallel, 2/4-pole, 3x-oversampled SVF filters, with continuous control of: filter type; number of filter poles; drive + saturation: cutoff; resonance; serial/parallel output; and output pan.
  • 3 envelopes. Predelay and 7-stage breakpoint included. Multi, single, loop, and clock triggers.
  • 3 LFOs, all with morphing waveforms, gate sync, and freq. control.
  • Modulation matrix with 15 nodes, each scalable from any of 60 sources to 135 destinations. Sample and hold, gated, and MIDI sources available. Many compound sources and destinations for rapid patching. Fixed- and variable-source modulations may shape and scale each other within the matrix.
  • Multi-mode glide and glissando, with unique glissando pattern generator.
  • Stereo effects chain with 2 tempo delays, 8-band chorus, realistic reverb, and advanced limiting.
  • Toggle-mode monophonic keyboard. Notes may optionally be stored in programs.
  • Flexible multi-channel architecture functions like a modular synth without needing rewiring. Monitor outputs at all mix points. LFOs, envelopes, and other modulation sources may modulate effects parameters.

  • MIDI I/O for all controls across two MIDI channels. Wheel, extended-range bend, and pedal controllers. Pgm#s and notes sent/received. 'All notes off' and standard MIDI cc#s implemented on main MIDI channel.
  • Fully instrumented panel with >200 controls and dynamic state display of oscillators, filters, envelopes, LFOs, and effects (in full versions). Lite version without dynamic state display for those with lower-powered computers.
  • Hover tips and help tabs. >3,000 words of context-sensitive interactive documentation.
  • 64-bit floating point audio processing at sample rate throughout, including envelopes and LFOs. All mix functions, pans, and switches are declicked and debounced.
  • Large, open, portable compiled function library available separately (seeSynthcore Library). Patches documented copiously, code documented expediently.

Performance

Unused functions in a preset are bypassed in code, to reduce CPU load, and all can be turned on and off without introducing clicks on the output. Typical load of the full version at 48kHz, on a Win64 4-GHz i7 and 2.5-GHz Mac Mini, is ~5.5% and ~25%, respectively. Those seeking more quality will find performance at 96kHz to be very decent.

Synthcore Lite

Some MacOS users report performance issues with the full version, and as it is also intended as a demonstration of the Synthcore source-code library, So I am also providingSynthcore Lite for MacOS. This version has the same audio quality, with 64-bit audio processing throughout, and complete declicking of all audio gain paths (a professional feature which is ~15% of the total audio processing load). However even so, on my old Mac Mini, by removing the dynamic graphics entirely, the app's CPU usage drops to
