BackMan v1.3.2


Reverses incoming audio signal in sync (it will follow host BPM). This plugin is specially useful on live gigs to make that "back spin" effect DJs usually does.
Specs:
- Very simple, just one slider.
- Slider on the right means forward (>>), slider on the left means backwards (<<) - Compensation control: Reverse playback timming compensation, fine tuning, useful to sync signals on different sound materials. - Gap position button: Defines where you want the slices gaps, turned off means the gap will be on each strong beat (useful for "backman sandwich" trick, see usage below), turned on means the gap will be delayed one 8th of a note to avoid the gap on fast high transients such as snares and kick on a regular drum loop. Gaps? what? where?: In a nutshell, BackMan is no more than two samplers recording the input and playing in reverse, but the actual trick involves a "flip-flop" process. On a 4/4 bar, counting 1,2,3,4 ("...this is rokanrol!") while one sampler is doing "record-play-record-play" the other is doing "play-record-play-record", this process takes one bar each time and therefore each sampler is taking two "slices" out of the input signal and playing them backwards, all in sync with the host BPM tempo. This process creates clicks on the signal because the sampled slices not necesarily begins and/or ends at zero volume point (zero crossing) thus creating nasty audible clicks on the audio. The only way I found to solve that was to tame those clicks doing very quick fade in/out over each slice, this creates very tiny gaps on the audio which aren't as bad as clicks but they still could be heard on certain situations. The most common case is having little gaps just over the snare and kick on a drumloop, that's why I included the "gap position" button, to be able to locate the gap away from the bigger transients. - USAGE - Important information - 1) The most tricky part is keeping the dry and wet signals in perfect sincronization so the fastest way is to put the big slider on the middle to be able to hear both signals, then use the little slider on the top to fine adjust the timing of the backwards signal (you can CTRL+Drag to fine tune) If you're using a drum loop for example, you need to sync both signals so both snares hits as close as possible (one over the other), and finally move the big slider to forward and backwards to see if they sound really natural when switching (even while you think they are synced is good to check this way). You'll need different values of the little slider depending upon the sound material, even if BackMan is calibrated to sound perfectly in sync, almost all kind of material needs a different value. So the procedure is the following: - a) Put the big slider on the middle and play the loop/song. - b) Check if both wet and dry signals are in sync, and adjust the little slider accordingly. - c) Move the big slider to check if they sounds natural when switching forward and backwards. - d) If they doesn't, fine tune the little slider again while switching as in step c) Now if you have them in sync, turning off the "gap position" button will cause the backwards signal to sound one 8th earlier, it will stay in sync but the sounds occur in different places. If you're using a drum loop for example you'll hear both back and forth snares at a distance of one 8th of a note, this could be useful if you want to break the rythm while switching directions. Other useful thing about the gap button is that you can define where the internal backman "flip-Flop" will occur, and thus where the slices gaps will be located. This is useful when you want to do the "backman sandwich" trick. - BackMan sandwich trick- This one is very useful to create "reverse tail reverbs" on the fly without having to record one long reverb tail and bouncing to a wave file. - Place a chain like this "BackMan-Reverb-Backman" - Turn off both "gap position" buttons. (otherwise the orignal input sound will sound chopped, not good for vocals or if you want your input untouched) - Turn off the second BackMan and get both (back-forth) signals on the first BackMan sincronized as explained earlier. - If the first one is in sync, turn it off and do the same to the second Backman. (save, load plugin presets is a good quick solution on this case) - Now turn them on and set both BackMans to reverse mode. Voila! instant backwards reverb! (take note that you need to put your source material a quarter or half a bar earlier) - Other cool tip is that by fine adjusting the little sliders on both BackMan instances you can make a straight beat to sound shuffled.
