Threshold problem

Thanks for the help!

yes i have atmega with protect bootloader and the firmware is 20100702

Well, that firmware version is certainly not the most updated...however, if using the protected bootloader chip then MCT is not compatible. Stop using it. You'll have to use the LCD on the front of your Megadrum to dial in all of the parameters. I believe Dmitri's new Megadrum Manager may work like MCT, but I haven't followed that thread enough to find out if it's out of "beta" phase yet.

As described before, if pads are too hot then you need either a potentiometer or a resistor for each pad that's too hot. Generally speaking, the 0-100K potentiometers seem to fit the bill. As Dmitri recently described in another thread, if you set the HiLevelAuto to Yes and strike the pad a few times, check the setting for that pad's hi level...if it's over 900 then the pad is too hot. The nice thing with potentiometers is that you can dial in the appropriate amount of resistance. They're just a bit more of a pain to solder in line with an audio cable.

Just FYI, it certainly is possible that pads can be too hot for some roland/yamaha/alesis modules as well. Some of my cymbal pads would consistently peak on my old TD-10 and until starting up with the Megadrum I never knew/realized that it was because the pad was too hot.

It's all my fault. Sorry Maylord for telling you to use MCT, I didn't know you were using the protected bootloader. I just thought it was a good way to show us how you set up your parameters.

There's one thing though... before recommending someone to use a voltage divider, shouldn't we make sure his set up and his board is working fine? I myself had 2 hot pads that were caused by loose screen mesh heads. I tight them up and now they're working fine! If I had put a voltage divider on them, the signal would have been "cooler" but certainly not accurate.

I'm not saying that Maylord is in that specific situation, but it could also be a crosstalk, a gain or a level problem.

hello guys

thanks for the replies

I did not know about problem MCT with protect bootloader does not work, so for now I'll try to put my old atmega without bootloader and install the latest firmware available.

Kim did not understand what you mean, you had got hot pad for a slow mesh head?

Are you saying you want to change your new Atmega chip for an old one? Dont do that!!!
You NEED the latest bootloader to use the latest firmware. Just keep everything up to date and forget about MCT.

Kim did not understand what you mean, you had got hot pad for a slow mesh head?

??
I use DIY screen (mosquito net) mesh heads. For each pad I use 2 layers of those screens. One of the 2 layers was loose (not firm), it was just as if I was hitting the cone directly.

I looked at your snare parameters, and maybe you should try these :

Put gain to 0 (not 4!)
Put Hi Level to "No"
Play arround with your "High level" value. 64 might be too low

Also, make sure that your snare is physically not in contact with any other instrument to avoid crosstalk.

Try to tight your mesh to make sure they are not just loose on your cone.

If none of these work, then go ahead and build yourself a voltage divider!!

No, i have two atmega, one "old" and another with protect bootloader

I understand your problem, i use TAMA mesh head, but i will change with roland or drumtec

I will try with your suggest

thanks for the help
