Quickstart guide
- Double click the machine to bring up the GUI
- Click the open button to loat a wave file from disk (44.1
kHz 16 bit uncompressed wavefiles only) or click the buzz
wavetable icon to import a loop from the wavetable (the
wavetable slot can be changed by typing in a different number
in the box)
- The upper waveform is the original sound, the lower one
is the current arrangement
- Rearrange slices by dragging them (you can drag from both
waveforms)
- Playback starts when the play botton of buzz is pressed,
and continues to loop until buzz is stopped.
To use liveslice with the buzz sequencer set the attribute
labeled "wait for trigger parameter" to 1. Now create a
pattern with the value 1 in the trigger column, an place it
in your song.
- Set the number of slices by clicking on the boxes next to
the "slices:" label
- Set the number of measures by clicking the "measures"
box
- Try randomizing the slices using the spacebar to toggle
between your current arrangement and a random one
- You can revert to the default (linear) arrangement using
the "Def" button
- Save a preset by right clicking on any of the 32 buttons
in the bottom half of the window
- You load a preset by left clicking or by using the
keyboard shortcuts (see below)
Presets can be exported and imported to / from .sli files
using the load / save buttons above the presets
Sample Import / Export
import
press the "open file" button to select a file from your
harddrive. Samples must be 16 bit uncompressed. The
selected sample is previewed - this can be turned off using a
machine attribute.
press the wavetable button to load a file from the
buzz wavetable. Select the slot by typing in a number in the
box next to the button. If you loaded a sample from disk you
can transfer it to the wavetable by right clicking this
button. Useful if you want to share your bmx file.
export
the save button exports the re-sliced loop and all individual
slices to the buzz wavetable. The loop is saved as it sounds -
with envelope modifications, but without any attached peer
effects - use the CnG recorder if you need those.
Parameter envelopes
There are four available parameter envelopes:
- Volume
- Panning
- Pitch
- Decay / Length
- Slice - an alternative to the drag'n' drop editing of
slices
- Probability - 0: slice will never play 100: slice will
always play
- Two PEER controllers
(can be configured to control any buzz machine.)
To activate, say the volume envelope click the button labeled
"Volume". Notice that the button changes color to indicate
that the green volume envelope is editable. Clicking the
button again will let the volume envelope remain visible but
not editable (so that you can view the volume envelope while
editing the panning envelope)
Peer controllers are configured by right clicking the machine
and using the assignments menu (this procedure might change
slightly)
Beneath the envelope selection buttons you find a bunch of
icons. The lock is for locking all sliders in the envelopes
(make them move together), the rest of them can be used to
apply common envelopes (rising, falling, random, etc.) the
slider below the icons define the bottom and top values (it's
a double slider).
Fine tuning your slices
You can change slice points by dragging them. Move the
pointer to one of the lines (upper waveform) and drag with the
left mouse button.
There is an auto quantize feature that will move the
slicepoints to the closest edge in the sound.
If you set the tempo or pitch to low values, slices will
overlap - if this gets in your way you can use CTRL + left
mouse button to change the decay of a slice, or use the DECAY
envelope
Slice Preview
Click the right mouse button to preview a slice. If you
click in the top loop, the sound will be played in the
original tempo, and playback will loop the entire file.
Click in the lower loop to preview a slice with all length /
volume / pitch / pan modifications
Wavetable Import / Export
Import
Type in the ID of the wave you want to import and click
the wavetable icon. ID's are in hex - be aware that buzz
sometimes displays the wavetable ID's in decimal - all ID's
revert to hex when a file is reloaded however :-)
Note that you can move a loop that has been loaded as a file,
to the wavetable by RIGHT-clicking the wavetable button -
useful if you loaded from file, and want to move your bmx file
to another computer.
Export
pressing the save-button with the little waveform label
will export the slice arrangement (what you see in the bottom
most waveform display) as well as all individual slices to
wavetable slots starting from position 40(hex). The start
position can be configured as an attribute - note that
attributes are always decimal, but I guess most buzz users are
quite skilled in hex / decimal conversions...
The slices are exported without any envelope modifications
(pitch, volume, pan, etc.) - if you want each slice as they
sound, re-import the exported loop into liveslice and do
another export.
Buzz syncronization
By default LiveSlice will sync to the buzz tempo. However
buzz does not report it's exact playback position to the
machines so LiveSlice needs a little help to tighten the
synchronization. To do this create a pattern that resets the
playback position to slice 0 at regular intervals (there is a
trigger parameter for that).
If you use alternating TPB values to control the groove, you
need to create patterns with the "sliceposition" parameter,
ranging from 0 the number of slices you are using.
If you change the bpm often, you need to turn off the BPM
synchronization of live slice by setting the "Sync to bpm"
parameter to zero.
Recording
There are two recording modes in LiveSlice.
- When you press record in buzz, all preset changes and
mute/ unmute changes will be recorded to the current buzz
pattern. This is useful for arranging your presets. First
create a number of different grooves (presets) straight -
stop-time - break - variations - silent, and then play them
using the keyboard, and record them to a pattern.
- When the record button in liveslice is pressed,
everything you hear will be recorded to presets 25-32 (the
last row of presets). The recording continues, overwrites
existing presets, until the record button is pressed
again.
Keyboard shortcuts
Preset control
the preset shortcuts are layd out as on the screen:
the first row of keys (1-8) selects the first row of
presets (1-8)
the second row of keys (a-k) selects the second row of
presets (9-16)
etc.
Save preset: hold down SHIFT while pressing the
corresponding key to
Slide display mode: TAB
Toggle Mute:
Return
Toggle Randomize:
SPACE
Toggle Recording:
[.] (the dot)
Envelope values:
Arrow keys (up/down changes value, left/right
selects slice)
Parameter desription
In addition to the GUI, Live Slice can be controlled by
various buzz parameters
- Sync to bpm
Can be used to disable sync to buzz tempo
- Playback pos
Forces live slice to play the slice at a particular position
in current arrangement
- Current preset
Switch to one of the 16 presets
- Manual
Override the preset in the GUI (tells live slice not to read
from the preset)
- Play slice
Manually play a particular slice, overriding the
preset
- Reverse slice
reverses the slice about to be played
- Wavetable slot
defines the wavetable slot for the import function
- Import wave
from selected wavetable slot
- Randomize
randomiz the slices in the GUI
- Revert
go back to linear ordering of slices
- Global Pitch
A note that controls the global pitch (C-4 is the
default)
- Inertia
not yet implemented
- Reset position
starts playing back from position 0 in the slice
arrangement
- Mute
mutes the sound

Attributes:
Internal tempo
Pr. default liveslice will follow the buzz tempo, and will do
some calculations on bpm changes - this is not good if you use
bpm changing groovemachines. Therefore you can use this to
disable bpm sync and have liveslice define it's own bpm
Crossfade length
Each slice is faded in and out to avoid clicks in the sound.
The slices are faded in before they actually start, to avoid
getting slow attacks (on snares for instance), but maintain
accurate timing. This attribute defines the lenght of these
fades
Pitch envelope range
In semitones - up to 240 semitones ! good to turn
everything into clicks
Interpolation
0 = none (cool lofi sound)
1 = simple linear interpolation
(hermite interpolation coming up...)
First wavetable slot for export:
defines the first slot for the export function
Play preview:
remember to disable previews if you want to load waves in a
live situation
Disable double buffering:
saves CPU, display might flicker a bit - use this if you have
to use the MME driver and / or your computer is slow
Cut slices on end:
If the pitch is lowered one octave, all slices are twice as
long - this can be changed using the length envelope, or by
setting this attribute to 1 and force all slices to be muted
before the next slice starts.
