Apricot

This is one of the best free synthesizers that I've tinkered around with. I'd say it's mostly ideal for tracks in the trance umbrella, because of the factory preset library (one of the best I've heard, including commercial synthesizers) and the unison per main oscillators being modeled off of the JP8000 supersaw.

The workflow of this synth is also really intuitive, everything is clearly laid out and quality patches can be dialed in with minimal effort. This includes the effects section, where adequate modulation and spatialisation can be done with little tweaking. This also applies to the arpeggiator / sequencer, where even if they're a little basic, great results can be made from them. Really nice for the price of nothing.

Well, this is my favorite go-to hybrid subtractive synthesizer. It has a powerfully flexible arpeggiator-sequencer on the effects page of Apricot, and it is freeware. I sometimes and always use this free FL plugin for my Sparta Bases. Thanks a lot, nakst.

The perfect combination of sound sources with ability to modulate. The only problem is the Mod envelopes do not have a visual representation of the ADSR. I had to do some hunting for the right spot to make adjustments.

Very impressive synth, Great arp/gate. Really fat meaty synth, two thumbs up. Great sounding effects, easy layout !.
