With over 1500 downloads in the first six months, this is the most popular item on this site. The library bundle 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.

Synthcore 2.1

Released on the first-year anniversary of Synthcore 2.0, The 2.1 upgrade includes the BEAP 5D Filter available for free on this site. Version 2.1 also adds shelving filters, parametric EQ filters, and more biquad filters. There are several FIR/IIR versions that are not biquad based. The Synthcore 2.1 library versions are redesigned so that coefficients can be stored statically within the filter calls, and are only recalculated if the filter controls change. As a side benefit of static coefficient calculation at Parameter value changes, the benefit of passing in constants is minimal, so the signatures are greatly simplified. However, if for example there are two channels with the same filter settings, this means the coefficients would be calculated twice necessarily, once for each channel. Multichannel versions are therefore included for more performance optimization.

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.

* 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.
