Thanks.... oddly enough I updated to the latest firmware just now, 20121203, and the pedal seems to be responding better than in the old firmware... also theres a bug, when scrolling to LoLev and HiLev, only one of them shows up at a time, I cannot toggle between the two anymore. Graph is still jumpy, but at least I have some play in the pedal.

10k resistor in line between tip and ring - Alt In = No - up position

Hi Level - 663
Lo Level - 568

Still doesn't seem right... *sigh*

With this functionality everybody can individualize his own reduction level for his own well being inside from value 0 to 127.

@dmitri what do you think about this feature? Thank you very much

I will first change reduction strength in the next version and then I will think about your suggestion.

Sorry, I didn't get what the problem is. May be you forgot to set AltEncoders to Yes?

Use the high impedance input - impedance switch in Down position and AltIn set to Yes.

Yes. Your very smart and I'm very stupid.

Graph is still jumpy, but at least I have some play in the pedal.

Tried that again, it's unusable. It goes from fully open 126 to fully closed 0 with no play inbetween... my previous worked better and I don't really know why...

So previously on the high impedance input without a resistor and with previous firmware version you got:

LowLevel - 303
HiLevel - 885


What do you get now with the new firmware version with and without the resistor?

2. Leave/set AltIn as Yes and leave/set the impedance switch in high impedance position.
3. Leave/set LevelsAuto as Yes.
4. Depress the pedal all the way up.
5. Set LowLevel to 1 and HiLevel to 1023.
6. Now start to lower HiLevel down as long as MegaDrum allows to (LevelsAuto won't let to lower it below certain level). Once you reached the lowest value, press the pedal and lower HiLevel by 5-10 and remember it.
7. Press the pedal all the way down.
8. Now start to raise LowLevel up as long as MegaDrum allows to. Once you reached the lowest value, depress the pedal and raise LowLevel by 5-10.

What LowLevel and HiLevel values did you get?

With 10k resistor i have:

Hi - 887
Lo - 400

1. Set AltIn as No and set the impedance switch to low impedance position.
2. Leave LevelsAuto as Yes.
3. Depress the pedal all the way up.
4. Set LowLevel to 1 and HiLevel to 1023.
5. Now start to lower HiLevel down as long as MegaDrum allows to (LevelsAuto won't let to lower it below certain level). Once you reached the lowest value, press the pedal and lower HiLevel by 5-10 and remember it.
6. Press the pedal all the way down.
7. Now start to raise LowLevel up as long as MegaDrum allows to. Once you reached the lowest value, depress the pedal and raise LowLevel by 5-10.

Without 10k resistor i have:

hi - 68
lo - 41

All right, thanks much for your proposal

ibanman555, I probably didn't make it very clear. I asked you to do it on the high impedance input:
1. with a resistor.
2. without a resistor.

whereas you seem to have done it with a resistor on the high impedance input and without a resistor on the low impedance input.

without 10k resistor

hi - 892
lo - 303

with 10k resistor

hi- 892
lo - 400

Looks like the resistor doesn't make any difference. Without the resistor on the high impedance input with AltIn set to Yes:

1. Set LevelsAuto to No
2. Set LowLevel to 400
3. Set HiLevel to 800
4. Set CC RdcLvl to 3
5. Set Big VU Meter to Yes

Exit the menu. With the pedal fully depressed (open) the pedal VU meter (top big VU meter) should be filled all the way to the right, isn't it?
Now start to press the pedal very slowly and watch the pedal VU meter until the pedal is fully pressed (closed).
1. Does the VU meter change?
2. At what pedal pressure position (3/4, 1/2, 1/4 of fully open) does the VU meter start to change?
2. Does it change in steps (2, 3, 4, 5, 6 ... steps) or gradually?
3. Does the VU meter go all the way to the left when the pedal is fully pressed (closed)?
4. Any other observations in relation between the pedal position and the VU meter?
