Samplerbox image has sample space on the SD card, used if you don't insert a USB stick.
It's initially filled with some sets I used for testing and also show some configuration methods.
It doesn't have to be so complex as you find here ofcourse :-)

0 Demo

This one has a lot of voices for various purposes (like testing by me).
All voices are based on the samples used in "3 Saw".
Most voices have a self-explanatory name.
The definition.txt has some explanatory comments.

It be can hard the hear the differences between some voices.
 - most wav' based on the same 4 wav's, just other naming or minor editing
 - the release sample is short pitch down wav (listen carefully)

The CCmap shows definition of
 - menubuttons on my midi keyboard
 - the three damp modes on the sustain pedal in voices  17/18/19

The notemap shows definitions of split keyboard and quarter notes.
It also shows the straight definition of the 88-keyboard.
Straight definition is redundant = not needed = just to show the system.
When editing via the webgui, redundant entries will disappear.

There is also a drumwav used in 5 definitions to show the difference between:
 - plain backtrack
 - backtrack triggered via keyboard: G#2
 - the wav played in once mode: C#2
 - the wav played in onc2 mode: D#2
 - the wav played in loo2 mode: F#2
The wav itself has an intro, a loop part and an outtro part.
If you're not a drummer, you may have a hard time to discern the  parts :-)
As they're all in the FX-track, they are voice-independent.

1 MidiPlayer
------------------------------------
This set contains the saw, some standard midi instruments, Gent's Belltower and two SMF files
The notemap and ccmap show how to start and loop SMF files.
"Mary had a little lamb" can triggered via A#3 and a drumpad on my keyboard
"Another one bites the dust" can triggered via C#4 and a drumpad on my keyboard
Looping of SMF can be toggled with D#4.
As "Mary" is played on acoustic guitar which is not in this set, it shows the use of default voice.
And I like it as a belltower song :-)
==>
I discovered the software used by samplerbox seems outdated / has been improved:
"Another bites the dust" runs into CPU issues in two fast playing fragments.
I don't have issues on my development PI, so food for thought for now.
I left it here as it gives you an idea what can / cannot be done.
And yes, it sounds better with the peak limiter switched on.

3 Saw
This set has no definition.txt.
It shows the simplest method of making an instrument.
