Fixed a bug with LCD handling.

Important firmware
update: incorrect LCD handling caused problems with fast drum rolls. This
version has the LCD handling revised and there should be no problems with fast
drum rolls. This time I'll keep secret where to download this firmware
version.

Small but important changes.

Small but
important changes to schematics:
In MegaDrum32 Digital board: R26 - from 220
to 4k7
In MegaDrum8 Digital board: R21 - from 220 to 4k7
In AVR-CDC USB
board: R4 - from 470 to 1k
In PIC18F2550 USB board: R4 - from 470 to
1k
With old values MegaDrum might experience resets when receiving Sysex
configs.

Virus in MegaDrum

I was made aware of a
virus which somehow got into the previous firmware version and was causing
MegaDrum to start sending unauthorized e-mails after an hour of drumming. The
latest release of the firmware fixes it and can be found in the usual place.

MegaDrum recall.

I had to recall all
MegaDrum modules manufactured before today due to a firmware bug which can only
be fixed at a factory. All these modules will be re-programmed with a latest
version of the firmware available on the Downloads page and
returned to customers free of charge.

MegaDrum is now plug-n-play.

Great news! Thanks to Synthex, not only one of the first to build MegaDrum but to make a contribution to the project, MegaDrum is now fully plug-n-play with a PIC18F2550 based true USB MIDI Board. Synthex developed the board schematic and, most importantly, a USB MIDI complaint firmware for it. You can see how it happened in these threads:

Firmware updated.

Another
firmware update. There was a small bug in the last firmware release, which could
potentially cause drum pads/cymbals overheating. So I updated all firmware
versions accordingly:)

Work on32 inputs version.

I've made some improvements in
the code so I've updated all firmware versions. In fact it's not the first time
I did it:) So if you downloaded the firmware a while ago I advise you to do it
again.
Also I wanted to let you know that the work on 32 channels version is
progressing well.
