Curve is a software synthesizer with an irresistible waveform editor, huge sound library and slick interface. Ideal for both experimentation and detailed tweaking at an excellent sound quality.

Feed Curve's oscillators, LFOs and envelopes with custom waveforms. For anything rhythmic from wobbles to FX loops and evolving pads. For broad oscillator timbres from deep basses to shrill, aggressive snarls.

A huge library will get you started, with quality presets by renowned preset designers such as Michael Kastrup, Pluginguru, Myagi, Xenos Soundworks, Soundsdevine, and hidden pearls from the Curve community.

Curve 2 provides completely new possibilities for experimentation and detailed tweaking, with a simple to use, immediate, slick interface.

Curve 2 is a very compact but also versatile and powerful sounding synthesizer. Compact because it comes with no additional FX. So you only get the Oscillators, Filters, Envelopes, LFOs and semimodular Routing Matrix. But that's a cool concept and works astonishingly well. The only drawback might be the lack of a manual. That's why I gave it only 9 Points.

The Name is program. It's all about curves. You can have up to 10 different curves at once. They are both: oscillators and LFO waveforms at once. All standard waveforms are on board and you can draw your own pretty easy and comfortable via dragging the mouse over the grid. With Rightclick you toggle between spline mode, edge mode and delete point mode. The grid is actually very helpful and awesome when designing rhythmic LFO patterns that can be further used on your Osc Volume for eg. gated pads. The LFOs can be synced or not synced to gate in, beat sync or free running up to audio (set it to note) so your LFO can now be used to modulate things via FM in the Routing Matrix. Great feature.

Curve2 has 3 Oscillator sections. There you can load two different waveforms from the Curves window which can be be mixed via LFO and Envelopes. Each section can be routed to the Filter section with the two Filters in different ways: 1 into 2, 1 and 2, only 1, only 2, 1 and 2 L and R, bypassed. The Filters are 6dB, 12dB and 24dB, all LP, then some BP, HP, NOTCH, PEAK (I love this one). 12dB and 24dB can selfoscillate - use keytrack in the matrix and have some fun. The Filters sound great and are per voice. Lovely resonance.

Last but not least the Envelopes. Instead of SUSTAIN you get a LOOP knob. Click the ZOOM TOOL in the corner and have some fun with Curve 2 own ENVELOPE DESGINER. :) Really great feature. So easy to come up with the perfect envelope. I wished all synths would have something like this.

The Matrix is semimodular and comes with lots of modulation and cross modulation possibilities. On top of it some features are only available only via Matrix (eg FM). Then you will get 4super controller hotkey thingies you can connect to mostly everything in Curve2 via drag & drop and control it via eg Modwheel, Aftertouch or something else.

Then you will get a pretty stunning and clean sounding Unison and Detune Feature with additional Spread parameter and a cool Damping option which balances out the sides vs the mids. And when you choose a odd voice number one voice will always be dead centre mono. Then some easy MIDI touch routing automation feature, some quality settings (oscillators are bandlimited or with aliasing, Eco mode etc), up to 32 polyphonic and an OUTGAIN dB option (pretty helpful if you press lots of keys and have lots of oscillator action going on so lower that to avoid clipping).

I surely missed something but the overall sound is pretty great and catchy: funky short arp basses are possible, lush stereo pads with lots of bass or even classic noisy supersaws. You don't need any fx because this can sound very fat on its own and gives you lots of control over the stereo field.

Awesome synth if you like to design your own waveforms or emulate classic stuff like 303 saw square waveforms or draw a MS10 50% square on your own. I dunno if it sounds like the real deal but it sounds great anyway.

Highly recommended. Lots of fun.
