I introduced two important changes to MegaDrum firmware starting with the version 20110411.

1. It now auto detects the crystal's frequency.
2. Added a MaxInputs configuration option. It defaults to 18 and can be increased up to the maximum for a given MCU - 28 for Atmega32/324, 56 for Atmega644. The lower MaxInputs the more Configs/Drum maps you can save in EEPROM and vice versa.

A caution: don't load a Config/Drum maps which was saved with MaxInputs value different from the current MaxInputs value.

With these two changes I will now need to include only one firmware file for each MCU variant - Atmega32, Atmega324, Atmega644.

Hi Dimitri. I'm not sure if i've understood. So we have to manually write down all the setting before upgrade, or we will loose all config settings? Is there another way to avoid manual re-setting?
I'm happy with my actual settings and i'm afraid...

Settings saved with a previous firmware version were never guaranteed to load properly with a new firmware version.
Use MDM to save and restore settings when upgrading the MegaDrum firmware.
