You have already seen that many sub-sections in the V-Synth have their own dedicated envelopes. Here are a few tips to help you make

the most of them:

Typical Envelope Shapes

The ADSR envelope was originally developed to mimic the volume, pitch and tonal changes of notes played on existing acoustic and

electromechanical instruments using only a few parameters. Here is a short list of a few real instruments and how to achieve similar results

using an ADSR-type envelope:

Composite TVAs

With only four parameters, ADSRs were always a compromise. Although unable to

simulate exactly how (for instance) a real piano note decays, most modern instruments

still use ADSR envelopes because they are simple. The V-Synth has a solution to this

problem: Each oscillator has its own dedicated Sub-TVA, and the signal is sent to a main

TVA afterwards. This allows for more subtle shapes while retaining the quasi-standard

four parameters (ADSR). Remember that many of the PCM waves already have a “built

in” envelope, so this is yet another factor to be added to the equation!
