Hi all! I've just released a free hybrid synthesizer called Apricot.

Free download: https://nakst.itch.io/apricot

As a hybrid plugin, it provides both 3 traditional subtractive oscillators, as well as a sample layer which can load both factory sounds and ones created by the user. This means it's capable of creating a wide variety of sounds, without overwhelming you with too much choice.

Audio demos of a few factory patches, without any external effects: And here are some additional demos kindly provided by one of the beta testers, @fdigl. These are also made without any external effects, and cover various genres including hardstyle and trance. Some of these are really impressive! Key features:
  • 2 main oscillators, with 6 different subtractive waveforms, modulatable phase offset and panorama, with unison modeled off the JP8000's supersaw. There is also an additional third oscillator, with less parameters, intended for use as a sub-oscillator.
  • Sample layer. This can run with key tracking enabled or disabled, and can run in both a looped mode or one-shot mode. There are currently 44 factory samples, ranging across 10 categories. The user is able to import their own samples from the standard WAV format, which will be automatically converted into the internal format. The sample database is managed using the FNV-1a hash algorithm to ensure that patches always load the correct sample.
  • Waveform previews in the GUI, with user customizable refresh rate.
  • CLAP support, with non-destructive polyphonic modulation and voice stacking.
  • 2 mod envs and 2 LFOs, each with 2 dedicated modulation slots. There is also a modulation matrix with 8 additional modulation slots, for a total of 16. There are over 70 modulation destinations, and 10 modulation sources. Modulation destinations are selected by clicking on the target control. Dials show both the currently set value as well as their value after modulation is applied. Hovering over a modulated control highlights the modulation slots that control it.
  • Arpeggiator and sequencer. The arpeggiator can be configured to not retrigger envelopes, useful for creating chiptune effects.
  • 5 effects: reverb (with 4 selectable algorithms), ping-pong delay, stereo phaser, parameter EQ, and a distortion unit. The distortion contains Light, Soft, Middle and Hard algorithms closely modeled after the Access Virus, to achieve a distinctive asymmetric distortion. While modifying the EQ parameters, a preview is displayed of its frequency response; this is immediately hidden when no longer needed.
  • Multi-mode filter that can run in low-pass, band-pass or high-pass modes, at 12dB/oct or 24dB/oct. There is a resonance, key track and drive control. The drive can enhanced with a "warm" boost, which mixes in a subtly "inflated" signal.
  • Streamlined two page user interface with scaling ranging from 100% to 200% and 2 skins.
  • Completely custom C++ DSP code without the use of libraries, for a sonic layer tightly coupled with the user interface.
  • Automatic CPU feature detection. DSP code optimized for those specific features will then be used, to reduce overall CPU usage.
  • Oh, and did I mention it's free? 8)
You can read more about the synthesizer on its website, https://nakst.gitlab.io/apricot. It is available for CLAP hosts and FL Studio (as a native plugin) on Windows, macOS and Linux. Apple Silicon hardware is supported.

Sounds interesting (and good)
Any link for us to try it? :)

Sorry, it's not quite ready for the public yet. I'd say the sound engine and GUI are pretty much finished, but there are still some boring things that need more testing, like saving and loading patches, importing samples, etc.

like the sound & the look. will look forward to seeing it released 👍

Wow CLAP support! I guess it will support MPE then?
Will it be cross platform?

The plugin does not support MPE directly, but I think most DAWs should be able to map MPE MIDI data into CLAP polyphonic modulation, which is supported.

As for platform support, it currently runs on 32-bit and 64-bit Windows, and I am working on a Linux version. I don't own a Mac though, so there won't be Mac support when I launch it. But it is a possibility for the future :)

Fantastic news!!! Thank you for making a Linux version!! I'm going to have to spread the news about that! :)

This could fill a few voids! :hyper:

Can't wait for it !
The Fx section looks GREAT

I like the grey frame and really think it would great to make the main frame of the GUI also in grey instead of orange

You guys are gonna love this one, trust me ;)

First of all, it looks really good. Color scheme and buttons are really cool, which is a +1 for me because free synths usually looks really bad. It looks like something between Sylenth and Serum.

Sounds really good too, can't wait to try it. Good luck.

New audio demos. As before, these use no external effects.
  • PL White Cloud and PD End of the Line — these two patches combine to exhibit the power of hybrid nature of Apricot. The pluck joins a thin pulse and triangle base with a harp sample, drenched in the "Atmosphere" reverb; and the pad unites an ethereal tonal noise sample with creamy unison sawtooths: https://raw.githubusercontent.com/nakst ... 0Line.flac
  • AR My Promise — this supersaw pluck uses the mod matrix to introduce a slight randomness on the filter resonance and phaser parameters, creating a wonderfully classic trance sound: https://raw.githubusercontent.com/nakst ... omise.flac
And here are some additional demos kindly provided by one of the beta testers, @fdigl. These are also made without any external effects, and cover various genres including hardstyle and trance. Some of these are really impressive! And finally, a screenshot of the parametric EQ popup:

Very, very nice! :)
