Genome Mapping

Here we offer a complete list of all the genes that make up Synplant's DNA. Please

be aware that although you may find some of them similar to the controls commonly

found in other synthesizers, Synplant genes should not be confused with traditional

synthesizer parameters. Many genes have a fairly complex relationship with each other

and their scales and response ranges have been extensively tuned so that useful sounds

can be created out of random "mutations".

For example, the "sample-and-hold" effect on Oscillator B (the b_sh gene) can intro-

duce a lo-fi "decimated" sound. Whilst it can be very cool for special effects, it may

not be something that you would want on the majority of your patches. Therefore, the

b_sh gene response is tuned so that it will only activate the sample-and-hold effect

at extremely high settings.

Furthermore, the range of all gene settings is from 0.0 to 1.0, even when the underly-

ing parameters that they control may be considered "bipolar". For example, the a_mod

gene which controls the pitch envelope amount. At 0.5 it is without effect, while at 0.0

it is maximum negative effect and at 1.0 it is maximum positive effect.

Finally, keep in mind that you can only edit the base genome of the seed. The further a

branch is grown from the seed, the more it will mutate and differentiate itself from the seed.

There is no way to control the exact changes in sound that take place when a particular

branch grows. This is something that you will just have to leave to chance.

Description

env_time

Controls the total duration of the sound. Closer to 1.0 the sound will have an infinite duration,

stopped only by releasing the key.

env_loop

Controls the looping time of the Envelope. A longer loop time than env_time means no

looping will occur.

env_tilt

Decides the tilt of the Envelope. Smaller values mean quicker attack and longer decay, whilst

higher values mean slower attack and faster decay. (The same envelope is used both for

modulation and volume.)

vol_atk

Shapes the attack phase of the volume envelope. A value of 0.5 gives a linear attack. Smaller

values give a slower build up, whilst higher values are quicker. (See Figure 9 Envelope Seg-

ment Shapes.)

vol_dcy

Shapes the decay phase of the volume envelope. A value of 0.5 gives a linear decay. Smaller

values give a quicker drop whilst higher values are slower. (See Figure 9 Envelope Segment

Shapes.)

vol_sus

Sets the sustain level of the sound. A value under 0.5 means no sustain. Higher values

equate to greater sustain levels. (At 1.0, the decay phase of the volume envelope will not be

heard at all.)

mod_atk

Shapes the attack phase of the modulation envelope. A value of 0.5 gives a linear attack.

Smaller values give a slower build up, whereas higher values are quicker. (See Figure 9 Enve-

lope Segment Shapes.)

mod_dcy

Shapes the decay phase of the modulation envelope. A value of 0.5 gives a linear decay.

Smaller values give a quicker drop and as expected higher values are slower. (See Figure 9

Envelope Segment Shapes.)

mod_sh

Sets the sample-and-hold frequency of the modulation envelope. Only very high values will

activate the effect and the higher the value, the slower the sample-and-hold rate.

mod_vel

Determines how velocity affects the modulation envelope. Lower settings lower the sensitiv-

ity and at 0.0, velocity will not affect modulation at all.
