Even when filter cutoff is set to 0, it is still letting some sound through.

A filter doesn't really have a '0'. It will increasingly attenuate (sometimes greatly) sounds above or below the cutoff value.

What I would suggest is that you use VOLUME/LEVEL to reduce the value. Assign the Mod Wheel as a control for the volume as well as the cutoff. You can then adjust the volume curve the way you want.

Perhaps you want volume to be unchanged for the high 80% of the mod wheel travel and then taper to 0 for 20% to minimum.

Here is an example of that:

1. INIT NORMAL (AWM2)
2. Edit Part 1 Common
3. Mod Control - Control Assign
4. Assign Part Volume to the Mod Wheel
5. Change Polarity to Bi
6. Change Ration to +63
7. Press the Edit User Curve button
8. Change output levels 2 - 8 to 127j

That 'step curve' will give you 0 volume for the 1st 1/8 and then max volume for the rest of the mod wheel travel.

Try that and see if it gives you what you need. You can adjust the user curve if you want.

Thank for the example! I actually found that the mini filter does filter out all sound at 0, but I still wanted to keep most of the the tonal characteristics of the other standard filters, so instead of applying your example to volume I applied it to insA cutoff on the mini filter effect. Worked pretty well for me, as having the slight mini filter sound characteristic for the first 20% sounded good to me still.

That's a good find. I'm curious as to what filter you were using initially?

Would you mind posting the configs you used for your first filter and then those you are using for the mini filter? I'd like to do some tests myself.

The data list doc shows the low/high cutoff values for many of the filters and some of them don't go to 0. They may go to 500 or 1k.

In particular a low-pass filter means to ALLOW frequencies below the cut-off so even a value of 500 or 1k can be significant when you are playing low notes.

So when you are interested in EXTREME values (either high or low) you may need to check the specs on the particular filter, and filter type, you want to use.

Using extreme values may also be impacted by any keyboard splits you are using and by the actual waveform samples used.

I was using the Dual LPF filter with distance set to 0 (the filter type seemed to let more upper harmonics through relative to the other filter types, which is what I liked best, but I only needed the one filter active). Everything else at also at 0 with Cutoff/Key at 31% and Gain at 230.

Mod wheel assigned to Cutoff:

• Curve type: standard
• Polarity: Uni
• Ratio: +15
• Param1: 4

Mod wheel assigned to InsA Cutoff (Mini Filter with the initial cutoff set to 0):

• User Curve: 1 at 0, 2 at 64, the remainder at 127
• Polarity: Uni
• Ratio +63

Let me know if you want to know anything else.

I suspect those 'more upper harmonics' were part of your problem. Since that filter is only 12DB per octave that means the drop-off won't be as steep.

You've found a solution that works so there isn't much incentive for you to try tweaking that filter but you could try a higher value for CutOff/key to see if that helps any. And experimenting with the resonance value for those low notes can alter the amount that gets passed/restricted.

Either the LPF24D or LPF24A filters with the steeper drop-off might have shown some effect too.

Glad you solved your problem.
