ALESIS FUSION EDITING AN ANALOG SYNTH PROGRAM
How to edit a VA synth program
To edit a VA synth (analog) program, select one as appropriate in the usual way using the data
wheel, the INC/DEC keys or a combination of the BANK keys and the A-P/1-8 keys.
For example, [ROM preset 1] K-1:
There are other examples in the ROM presets to choose from as the basis for your edit.
Whichever you choose, press the EDIT key located around the data wheel.
To edit the synthesiser parameters, press the SYNTH soft key (highlighted on the left of the
LCD in the screen shot shown below). You will see this screen:
You can now choose to edit the oscillator(s), filter, envelopes and LFO(s) using the soft keys
down the right hand side of the LCD.
Other aspects of the program can be selected using the soft keys down the left of the LCD.
This ‘How To’ tutorial follows a sequential approach - i.e. oscillators then filters then envelopes
then LFOs, mod matrix, effects. You can use the bookmarks in this PDF to skip directly to the
section you want.
For detailed information about the principles employed in Fusion’s VA synth, please refer to
the in-depth analog synthesis tutorial that is also available for download hereabouts

How to change waveforms
To change the basic waveform, press OSC and, if necessary, SELECT:
You can select the oscillator (up to three) in the EDIT OSC field (highlighted in the above
screen shot).
To change the waveform, move the cursor to the TYPE field (below the waveform display)
using the NEXT (or PREV) key by the data wheel and select from SAWTOOTH/TRIANGLE,
PULSE/SQUARE, SINE and three types of noise. You can also select EXT IN for processing
external audio inputs through Fusion’s powerful synth engine.
Select other oscillators (they need to be switched on of course) and select the waveforms as
required.
How to change oscillator pitch
Press PITCH. You will see this:
You can tune the oscillators in semitones or you can fine tune (detune) the oscillators against
each other for a richer, more chorused/ensemble sound.
RANDOM TUNE makes each note you play have a slightly different tuning (like old analogue
synths that had poor tuning stability!) and the degree of this is set using the percentage value.
At any time, press EXIT or SYNTH to return to the main menu.

How to balance / mix the oscillators
Press OUTPUT to see this screen:
Move the cursor to the OSC VOLUME field using the NEXT (or PREV) key by the data wheel
and use the data wheel to set a value as appropriate.
Select the oscillator you wish to adjust using the EDIT OSC field (highlighted in the above
screen shot)
When OPTIMIZE TO MONO is unchecked, an extra PAN parameter is shown:
This allows to ‘spread’ the three oscillators across the stereo image for a wider sound (useful for
ensemble sounds such as strings, pads, etc.).
At any time, press EXIT or SYNTH to return to the main menu.

How to quickly configure the VA synth’s oscillators
A quick way of mixing, tuning, selecting waveforms, etc., can be done in the CONFIG page:
Using the VIEW parameter (top right and highlighted in the above screen shot) you can select:
OSC ENABLE (i.e. oscillator on/off)
OSC TYPE (shown - selects the waveform)
OSC COARSE TUNE
OSC FINE TUNE
OSC RANDOM TUNE
OSC VOLUME
OSC PAN
Use the NEXT/PREV keys to navigate to the 1, 2 and 3 fields below and use the data wheel to
change the selected value.
This page is useful as you can perform these functions relative to each oscillator without
extensive page swapping.
Down the bottom of the page, you can see the VA synth’s Ring Modulator which can be
switched on or off and the source for it selected (OSC1 x OSC2, OSC2 x OSC3, OSC1 x
OSC3 or OSC1 x OSC2 x OSC3),
At any time, press EXIT or SYNTH to return to the main menu.

How to change the filter
Press FILTER. You will see this page:
The filter can be totally bypassed if you want (sometimes useful!) but moving the cursor to
TYPE allows you to select from a wide variety of different filter types:
LOW PASS
HIGH PASS
BAND PASS
BAND STOP
BAND BOOST
RP LOWPASS (a modelled filter based on a famous ‘2600’ synth classic)
VOCAL FORMANT 1, 2 and 3
The STEEP parameter allows you to set ‘slope’ of the selected filter type. The steeper the
slope, the more dramatic the filter effect (2- or 4-pole are the most commonly used filter types).
NOTE: On some of the filter types, this parameter is unavailable.
FREQUENCY sets the selected filter’s cutoff frequency. You will see that the graphic updates
as this parameter is altered. This is the most obvious control to head for as it has the most
dramatic effect .
NOTE: You can also - and more easily - affect filter cutoff using the matrix of real-time controls
on the front panel. Select the FILTER row and use Knob 1 to adjust filter cutoff in real-time.
RESONANCE emphasises the area around the cutoff frequency and your filter ‘wow’ effect will
take on more of a ‘weeeow’ characteristic.
NOTE: You can also - and more easily - affect filter cutoff using the matrix of real-time controls
on the front panel. Select the FILTER row and use Knob 2 to adjust filter resonance in real -
time.
Fusion’s filter is the key to many of the analogue sounds created in the VA synth. There are no
rules to its usage - be prepared to experiment!
At any time, press EXIT or SYNTH to return to the main menu.

How to change the envelope(s)
To access Fusion’s envelope generators, press ENVELOPE. You will see this screen:
Here you can set the usual attack, decay, sustain and release parameters. By default, Env 1
and 2 are always present when a new program is created - Env 1 controls amplitude and Env 2
controls the filter although a Fusion VA synth program can actually contain up to eight
envelopes. The envelope to be edited can be selected using the EDIT Env parameter
(highlighted in the above screen shot).
Move the cursor to the appropriate fields to set attack, decay, sustain and release. The times
are shown in seconds and levels shown in percentage.
All envelopes are identical.
Extra envelopes can be added by pressing ADD ENV and these can be assigned to almost
anything you want in the MOD matrix (more later). Unused or unwanted envelopes can also be
deleted using DEL ENV.
Because the envelopes are routed to other modules by way of the MOD matrix, JUMP MOD
takes you directly to the selected envelope’s connection in the matrix where you can set
modulation levels, etc., (and in the MOD matrix page, you can jump back to the selected
envelope).
At any time, press EXIT or SYNTH to return to the main menu.

Changing the envelope ‘curves’
Pressing SHAPE shows this screen:
Such is the degree of control offered by Fusion, you can set the curve or ‘shape’ of the
individual stages of each envelope generator. This allows precise control over a sound’s
articulation.
The graphic shows you the curve as the parameters are changed.
At any time, press EXIT or SYNTH to return to the main menu.

How to change the LFO(s)
Pressing LFO will show this page:
A Fusion VA synth program can contain up to six separate LFOs (although the norm is usually
one or two - one for vibrato and maybe another for, say, filter sweep). The LFO you want to edit
can be selected in the EDIT LFO field (shown highlighted in the above screen shot).
The most obvious parameters to change are TYPE (i.e. the LFO’s waveform) and/or RATE.
NOTE 1: In the case of the TYPE parameter, you can also use the SHAPE parameter below it
to change the ‘shape’ of the waveform. When SAWTOOTH/TRIANGLE is selected, the
SHAPE control changes it continuously from triangle to sawtooth:
In the case of PULSE being selected, you can alter the width of the control waveform with the
SHAPE control:
NOTE 2: In the case where SYNC is set to external MIDI clock, the RATE parameter is not
available. Instead, you can change the ‘division’ (for example, 8ths, dotted 8ths, 16ths, dotted
16ths and many more) to synchronise the LFO to the tempo of your track. When SYNC is set
to NONE (as shown above), you can use the RATE control to set the LFO rate as normal.

How to make changes to modulation
Fusion’s mod matrix is a powerful component in Fusion’s synthesis armoury and allows you to
route almost any controller to almost any destination - pitch, timbre (tone), amplitude, panning
and more. This is done in the MOD pages and pressing this will show something like this
screen:
Here, you see a list of the mod assignments and you see the source and the destination for
each one (for example, or ). To make any changes to these,
move the cursor to the modulation ‘connection’ you want to edit and press SETTINGS. You will
see this screen:
Probably the first (and maybe only!) parameter to head for is the AMOUNT parameter down the
bottom of the screen (as highlighted in the above screen shot). Use the data wheel to set a
value (to hear your changes as you adjust the parameter, repeatedly play a note on the
keyboard as you adjust the parameter).
You can, of course, change the connection’s source and/or assignment but for most ‘tweaks’,
simple adjustment of the modulation amount is usually all that’s required.
To select another modulation connection, either press EXIT to return to the ROUTES page or
move to the EDIT MOD parameter at the top of the screen and select another using the data
wheel or INC/DEC.
To ‘cancel’ a connection, either set its AMOUNT to 0.00% (press INC and DEC simultaneously)
or, in the ROUTES page, press DEL MOD. The first of these two options is safest in case you
maybe want to re-instate the mod without having to build the connection from scratch.

How to add a new mod route
If you are feeling adventurous, you might want to add your own mod routing. It’s actually not
difficult. A silly example perhaps but let’s say you want to route Envelope 1 to pitch to create
an octave sweep for a special effect.....
In the ROUTES page, press ADD MOD. You will automatically be taken to this screen:
As you can see, no assignments are made.
In the SOURCE field, use the INC key until ENVELOPE is shown:
By default, ENV1 is selected in the index field so you don’t have to change that. Now move
the cursor to the DESTINATION field:
