6.1.2.6. Sum
Sum: Source 2 is added to Source 1. In the example below, LFO 1 (a slow sine wave) is
being modulated by LFO 2 (a faster sawtooth wave), with the Amount set to 0, 0.5, and 1.0.
Compare with Diff; here, the resulting waveform has the same polarity as Source 2.
6.1.2.7. Direct routing
Direct Routing: This option subdivides the Mixer into two separate sources, which can be
routed to Destinations 1 and 3 (Destination 2 is deactivated). This is useful when you need a
couple more basic modulation paths.
