FAC Tuning Tweaks

Creating A Header Sheet for xMem Tunings

This post is on how to create a header sheet for the xMem sections of the SAT IV. There are probably more ways to do this than the one contained in the video, but this one works nicely and is fairly quick. This method uses Excel and Word. I hope this video can be used by those with only limited experience with Excel.   Those with a basic knowledge of Excel, will have no problem with this method. (Contains video) Continue reading

Check/Correct All Partial Changes Using the SAT’s Partial Change Correction feature

This Partial Change Correction (PCC) feature is relatively new to the SAT IV's programming. So if your SAT doesn't seem to be responding to the STO + MSR command it's program may need to be updated. Being able to correct partial changes is unique to the AccuTuner.  An FAC tuning has fewer partial changes (3) than any other tuning system,  and yet it is the only device capable of  correcting them. (Contains button pressing video). Continue reading

Double Octave Beat (DOB)

DOB allows us to easily stretch or contract a template or tuning stored in the SAT. A DOB setting of .1 expands the double octave - increasing the beat rate of the double octave - by one tenth of a beat per second. A negative or minus DOB setting contracts the width of the double octave thereby decreasing the beat rate of the double octave in one tenth beat per second increments. DOB can be used where ever more or less stretch is needed. DOB is a feature found on the Sanderson Accu-Tuner III and IV. Continue reading

Adding Stretch to the Bass Using PCC

In addition to correcting errors at partial changes, the Partial Change Corrector (PCC) may also be used to add stretch to the bass. The main difference between using PCC in stead of DOB, is that with PCC the adjustments stay with the tuning after the SAT is turned off, whereas the DOB settings are not. Continue reading

Using a Custom Over Pull for Pitch Corrections

Programming a custom over pull is so easy it's not worth making a video of it. The custom over pull is 'activated' just like the regular pitch raise feature, but instead of rolling off onto the BlueShift, after MSR stops the lights, roll off onto the Green Shift.  Rolling off on to the GREEN shift activates he Custom Over Pull and uses the amounts stored on Page 123.
