Detailed Program Editing Using Filters

To realistically simulate the slight change in pitch that

occurs when a string is plucked or at the attack of a brass or

vocal sound, you can use the EG to create a subtle change in

pitch at the attack.

Portamento

Portamento makes the pitch change smoothly when you play

the next note before releasing the previous note.

The Time parameter controls how long it take the pitch to

change. As this value is increased, the pitch will change over

a longer time. With a value of 000, there will be no

portamento.

You can turn Portamento on and off via SW1 or SW2, by

assigning them to Porta.SW CC#65.

Using Filters

The filters allows you to diminish or emphasize specified

frequency areas of the sound.

The tone of the sound will depend significantly on the filter

settings.

The basic filter settings, including the routing, type, cutoff

frequency, and resonance, are set on the P3: Filter page.

Filter Routing

Each oscillator has two filters, Filter A and Filter B. The

Routing parameter controls whether one or both of the

filters are used, and if both are used, it controls how they are

connected to each other.

The Single routing uses only Filter A as a single 2-pole,

12dB/octave filter (6dB for Band Pass and Band Reject).

The Serial routing uses both Filter A and Filter B. The

oscillator first goes through Filter A, and then the output of

Filter A is processed through Filter B.

Parallel also uses both Filter A and Filter B. The oscillator

feeds both filters directly, and the outputs of the two filters

are then summed together.

The 24dB/4-pole routing merges both filters to create a

single 4-pole, 24dB/octave filter (12dB for Band Pass and

Band Reject). In comparison to Single, this option produces

a sharper roll-off beyond the cutoff frequency, as well as a

slightly more delicate resonance. Many classic analog synths

used this general type of filter.
