The software for the LXR can be updated using the memory card.
10.1. UPDATE PROCEDURE
> Copy the latest LXR_V2_xxx.img to the root of the SD card.
> Push and hold the encoder button while turning on the device.
> “LXR Bootloader” will pop up in the display.
> The LXR will check if the firmware image is valid and has the proper checksum.
> If the check is passed, the update will be installed.
> Do not turn off the power during installation!
> Once done, the LXR will prompt you to reboot and the new firmware will be
running.
10.2. BOOTLOADER ERROR MESSAGES
> LXR*.img Not Valid!
File doesn’t seem to be a valid firmware file. File header not matching
> LXR*.img Wrong size!
Filesize differs from the size specified in the header. Probably an incomplete
download.
> Wrong Checksum
File corrupted. File content does not match the checksum. Probably a download
error.

This chapter will introduce you to the very basics of drum synthesis. Of course, this
is just a small pointer in the direction of a few classic drum sounds. There are
many more sounds to discover beyond the well-known drum sounds of the
analogue classics. Nonetheless we will mostly focus on generating these, because
they provide a good starting point for further exploration.
11.1. KICKS
The basis of nearly every kick sound is the simple combination of an oscillator and
a decaying envelope modulating its pitch. The first 3 voices are perfect for this!
OSCILLATOR
A good starting point is a sine oscillator with a pitch around 30 to 35.
AMPLITUDE ENVELOPE
To decide how to set up the envelope, let's think about the kick sound. A kick has a
sudden impact, so we want no attack (set to zero) since the sound starts with its
maximum amplitude.
The decay controls the length of the kick sound. For the average kick a decay in
the range 20-30 and a slope around 25 (exponential) gives a nice, not too short, not
too long kick. For those booming 808 kicks you may want to set the decay higher.
PITCH ENVELOPE
To get some 'oooomph' and punch into your sound you need to set up the pitch
envelope.
Try a decay and slope setting similar to the amplitude envelope as a start. All three
parameters, decay, slope and modulation amount, have a great impact on the
sound of the kick.
