67 Subtractive virtual synthesizer - FulSynth

the Delay Unit might create unwanted situations when they are switched, cutting

down the main signal flow.

The FulSynth amplification is balanced. It takes into consideration the human

ear’s frequency response. However, volume conflicts might appear when all tools are

interacting, especially when the four possible sources are active. Both oscillators

alone are efficiency reproduced, but when the Noise Generator Unit and the LF-

Rhythm Generator are added the volume of the oscillator decreases and the main

output signal sounds too low and unclear.

The amplitude issues might also be related to the inner-communication design.

FulSynth’s signal flows from one abstraction to another through the through~/catch~

Pd functions. The amplitude seems to decrease when the channel these functions

create carries too much information. However, it is not only because of this that a Pd-

developed synthesizer seems to be less efficient in amplitude terms. In Chapter 4,

section 4.4.4, the graphics showed the amplitude level in Volts obtained for every

device. FulSynth obtains the highest level (Figure 4-XXVIII), close to 1.5V, but when

it plays at its maximum volume the sound reproduced by the soundcard is much lower

that the level obtained with any of the other three. The use the commercial analysed

devices make of the soundcard is much more efficient.

In terms of wave shaping, filtering and amplifying Arturia Minimoog gives

the best readings. However, all three devices include features that would improve

FulSynth considerably.

In Pd development terms it is absolutely possible to improve the FulSynth

programming. The FulSynth filters and envelope generators are for instance not self-

designed functions. An advanced Pd developer using electronic engineering concepts

might obtain better filtering results. Further learning in this language will create a

better FulSynth Pd synthesizer. It will be important to learn more functions and

procedures, but it will be essential to understand better the Pd-computer

communication and to see where Pd’s limitations exist. I
