14. you are using a slider set to dB units This is because the minimum value INF is zero and not a negative value You have to use other units for this purpose You can also use Mixers as amplifying devices without the need to use shift left modules However you can not do this with just one input For example if you want to amplify a signal by 12 04 dB you would have to introduce the same signal in the 4 inputs and set the control values to 0 dB Knowing that adding two identical signals will increase the original value by 6 02 dB and repeating the operation for the other two inputs we will have the desired value 6 0246 02 12 04 If we wanted a 10 7 dB amplification we 63 64 would have to set the control values and adjust them accordingly to obtain the desired value at the output If you double click on the mixer in Edit mode you will be able to edit the control values amplitude values from the Mixer Options dialog box You can choose between editing them in dB float dec hex hertz and miliseconds Mixer Options Edit values in Yolume of missing dB controls A Float Control 1 il 6 020601 a a Control 2 l 6 0206D1 3 Dec Control 3 6 070601 CA Hex C Hertz Control 4 6 070601 Ca Mili seconds In order to optimize DSP power we advise you to start with the first channel and then the channel immediately after and so on without leaving gaps between them 25 PITCH TRACKER Number of instances
