The number next to Signals Used shows the number of internal buffers that were needed by Pulsaret to connect the signal objects used in the current signal network The number of Function Calls gives an approximate idea of how many calculations are being required for each sample of audio Both of these fields will update whenever you change the number of audio objects or how they are patched together Vector Optimization only applies to PowerPC computers Vector optimization allows four samples to be processed within the space of a single instruction However not all audio signal processing algorithms can be optimized in this way for example recursive filter algorithms are substantially immune from vector optimization Pulsaret itself no longer uses vector optimization but third party audio objects may still use it In other words unless you are using a vector enabled third party audio object on a PowerPC computer this setting will have no effect 1 Mixer e faders and solo mute Vertical faders 1 2 8 receive stereo granular stream audio signal Master gt channel on the mixer right sum all stereo faders and output audio data on the physical hardware audio device The mute and solo buttons labelled M and S respectively e Activating the mute button mutes the channel i e the affected channel can t be heard in the final mix e Activating the solo button mutes every other channel i e only the affected channel can
