Transition is a very lightweight/low memory Instrument which is designed around the idea of cross fading between 2 waveforms using an LFO. The included 127 waveforms were multi-sampled at 96khz from a Korg NTS-1 using various different Oscillator Models. They are single cycle & so use very little memory & sound very clean & strong. The NTS-1 is a great little synth that allows loading 3rd party oscillators & some of these are very interesting.
Alternatively the Modulation Wheel can be used to control the fade position in real-time instead of the LFO.
