Alt Sampling Alg and cymbal choke

[iancote]

Hello!

I recently received my 32 input megadrum and have been having fun getting the pads dialed in. For reference, I've got an older Hart Dynamics kit with the really simple plastic crash cymbals (one piezo and a membrane switch choke strip). When I first hooked everything up and turned it on, the whole kit was going wild with everything triggering like crazy. I settled it down by selecting the "AltSamplingAlg" option and was able to get stuff playable except the hihat. Reading through the forums looking for hints I saw a note from dmitri that no one used that option and it wasn't well tested, so I went back and re-did things without it (slamming all the inputs to threshold 100 at the start let me dial everything in). Now I've got things going better than before EXCEPT, for the life of me, I can't get my cymbals to choke anymore. I've attached two screenshots, the one that has the altsamplealg and the working choke, and the one without and the not working choke. I even tried just copying the sysex from the working version to the new set with no success.

I'm also not really clear on the meaning of "disable" as an option for inputs or the 3rd zone. I've seen a number of times where even disabled, I'm still getting midi notes for that zone.

Thanks,
-ian

If you have a problem, it not the best idea to plug everything into all inputs and the trying to troubleshoot.
1. Disconnect everything.
2. Disable 'Alt Sampling Alg'.
3. Disable 'New Algorithm' in the Pedal settings.
3. Connect only one pad.

Now describe what the problem is with this pad and show settings for this pad.

Hi Dmitri, thanks for taking a look.

The issue I'm trying to solve is the choke on my cymbals (plastic Hart Ecymbals - just a piezo and a membrane choke switch on the bottom). I had originally tried to set up everything with the AltSamplingAlg set to ON. At that time, the cymbals worked as simple single zone with choke (that is the "worky" screenshot). Then reset everything and started over with AltSamplingAlg set to OFF and have most everything working really well, except now the choke doesn't work on the cymbals.

I disconnected everything
I have AltSamplingAlg off already - that was my goal to show in the two previously loaded screenshots
I've turned off "New Algorithm"
This only has the one cymbal plugged in.

The process I've been following to set the cymbals is:
Starting with a threshold of 10, keep bumping it up until I no longer get random triggers.
I set the Gain to 0, check the "High level Auto" box for both the bell and edge. The type is set to "Dual" and "Switch"
I bash the cymbal a few times to get a reading. For these, the Edge level lands somewhere in the 500s. I uncheck the "High level auto" switch and then send the config again.

I then follow this process:

Previously with AltSamplingAlg on, when I hit a cymbal I'd get a bow note (77) and then if I pinched the choke I'd get a couple aftertouch (grey on the midi log) type notes.

With AltSamplingAlg off, now all I get are 3rd zone (78) notes. I even tried disabling the 3rd zone and sending that config, but it still registers as that note.

I've attached a couple screenshots, one of the current config for that pad after the process above, and the midi log showing the 3rd zone notes even though that zone is disabled.

Thanks again - I've been really amazed at the results I'm getting on the rest of the kit. Much nicer than the roland td10 I'm replacing.
