The most important change is the addition of 2 more Modulation Sequencers, and now they can have direct control over each Oscillators frequency. This change alone makes it possible to create sophisticated one finger style polyphonic sequences by being able to control each oscillator independently. As well as this comes 2 more Gate Sequencers with direct triggers for Envelopes 3 and 4, and also adds the ability to trigger the volume of each oscillator independently. The sequencers can also be assigned via the modulation matrix along with all other Sources.

A click is produced when a very fast level change in the audio signal occurs. You can easily check that on your home stereo when you play back a CD and switch the Source Selector back and forth between CD and a source that doesnt play anything. The brightness of the click depends on the speed of the level change. The faster the level changes, the brighter is the click. So, the level change speed can be compared with the cutoff of a lowpass filter.

There is an easy formula for it: Lets consider a level change from full to zero or from zero to full output from one sample to another on a machine that uses 44.1kHz sample rate.

So, we first transfer the sample to milli seconds:

1 sample equals 1/44100 second, which is = 0.02267573696ms. To calculate the cutoff frequency of the click, just use this formula: Cutoff Hz = 1000 / Level Change Time ms

which in the example results in: 44100Hz = 1000 / 0.02267573696ms
