Most of the time for me, bitcrusher sample bit 10, sample rate 22050 is the sweet spot. I've tried doing it to the same sample two times in a row, but it doesn't seem to pile on itself to keep crushing over itself. I guess I could resample and bitcrush it again but that's too much effort.
I was overwriting the files. But your way you could bitcrush it to a new sample which is the default and then, in JJOS2XL, you can combine two samples quick in TRIM MODE. It's called COMBINE A+B about two clicks over from bitcrush. That way you get a combined wet and dry signal. I haven't experimented with that too much.
I, too, like to turn Big Grunger down. The default setting of 4 is too grungy in a bad way.
Here's an idea to speed up your workflow. If you already know you want the Bit Grunger FX on your sample, you can run the incoming signal through the internal FX on the way in the first time you sample it. Go to Effects then hit GoToMix (F5) and then turn Input Thru ON. Then go down to mixer on right side and click FX1 and the SEND amount.
Now you have bit grunger on your original sample, no resampling required. Now do your normal Bit Crusher 8 bit routine. Hopefully this saves you a step. See if applying bit grunge first during original sampling, THEN bit crush changes the sound much for better or worse. It's save you time.
Here's my routine (I'm still working to perfect it and speed it up)
1. Sample
2. Save sample and go to MODE + PAD6 Trim Mode
3. First I normalize the sample.
4. Modify begin and end points
5. Then in the same screen, [TRIM MODE] I use bitcrusher sample bit 10, sample rate 22050. I overwrite existing file. That was quick and easy. Or save to new sample name and then combine. Now let's go to FX.
6. Assign it to a program and pad and then hit F6 and go to FX and assign it to ST FX1 SEND 100 Do this for all pads within the program that you want to send through FX. SHORTCUT: Hold shift and click all and you can change all 16 pads at a time. FAST!
7. Mode + Pad 12 Effects
8. First on the MASTER channel. I have EQ and COMPRESSOR.
On EQ I have 8000,3500,500,60 set at +2,+4,-3,+5. This example takes out the "harsh lower mids"
On the compressor we want to be mild here because we're going to run it into another compressor again.
Set the master compressor at -20 threshold, +3, ratio 8:1
9. Now let's do FX1 and FX2. Set it so that FX1 runs into FX2. This is important.
Set FX1 to Bit Grunger. Set it to depth of 3. Experiment if you want with values 1-8
Set FX2 to Compressor again. This one with -15 threshold at -15
OPTION B: Set both FX1 and FX2 on Bit Grunger but dial them both down to 1, or set the first to 2 and the second to 1. You get bit grunging fed into more bit grunging on FX1 feeding into FX2. Could get extra crazy but tamed by dialing it most of the way down.
OPTION C: Run sample through FX1 when originally sampling. Can run sample through filters or EQ on the way in as well. This saves time and, since FX is already applied to sample while we sampled it, it frees up FX1 and FX2 for later uses. The time saving option I proposed to MGoolas above.
You only have to do steps 1-5 for additional samples.
