waveform is an additive representation of your waveform that updates in real time. This is handy as it enables you to see how and where you're introducing different frequencies to your sound. You can't actually edit the additive 'graph' yourself but it's nice to have it available.
Each of Curve's three oscillators can host two separate waveforms and includes a crossfade control that allows you to mix things up a little. Apart from that you have fairly ordinary Pitch, Detune, Pan and Volume controls. Routing to the filters is handled by a dropdown menu in the top right of each oscillator's 'box'.
as if you'd gone for the max attack of 32 seconds. The only part of the envelope you don't get direct control of, apart from its length, is the release - not really a problem though.
After the filters and envelopes and over to the right we have Curve's bank of four LFOs. Again, they're brain dead simple to use. The waveform window is easy to You can control triggering, speed Curve has two filters that each use and you get to see and hear and level but for routing need to offer ten filter types: 6db LP and the results of your tweaking head over to the mod matrix. The instantly. Personally I'd love to be HP, 12db LP, HP, BP, Peak and Notch, and 24db LP, HP and BP. A mod matrix is another example of able to flip it into Additive mode and get busy with the partials but nice selection and it has to be said well thought out design. Everything is clearly labeled and that the filters sound good, very can also see that that isn't quite fairly obvious.

You can set them all at the same envelopes.

One handy thing to mention is that Curve looks after looping the waveform for you so no need to worry about clicks or funny bits in your sound
