A linear voltage-controlled amplifier (VCA) uses a simple mathematical relationship between control voltage input and signal level output – for example, 50% of nominal control voltage in would result in the output signal being at 50% of the level of the input signal. This, however, is not how our ears perceive loudness; a sound must be amplified by 10x in order to be perceived as twice as loud. gas finder mn This makes a linear VCA desirable for scaling control voltages, but perhaps less so for scaling audio signals. If you connect an envelope generator with an exponential output to a linear VCA, then you will get the desired aural result. Confusing? That’s why it’s great when an envelope generator or VCA has a switch or control to vary it between linear and exponential response. A linear mixer is similar to a linear VCA: “half” on the input level control equals the output having half the voltage swing as the input. t gasthuys Again, this is fine for altering control voltages, but not for mixing audio signals; in that case you want a mixer with exponential controls.

Tracking usually refers to how well an oscillator follows the pitch control voltage (CV) sent to it. As the voltage rises, the oscillator “tracks” it and produces a higher pitch. Most (but not all!) synths follow a 1 volt per octave system where a rise of 1.00 volts on the pitch input should produce exactly a doubling (one octave rise) in the oscillator’s pitch. If this is indeed what happens, the oscillator has good tracking. gasco abu dhabi address If the oscillator goes slightly out of tune, it is considered a tracking error, or to have poor tracking.

Sometimes you will find voltage-controlled filters have a “tracking” switch for a CV input where the pitch of the filter’s corner frequency only rises at 1/3, 1/2, or 2/3 of the corresponding change of the pitch input. This can prevent high notes from sounding too bright without the bass notes sounding too dull. p gaskell Sometimes you will find voltage-controlled filters have a “tracking” switch for a CV input where the pitch of the filter’s corner frequency only rises at 1/3, 1/2, or 2/3 of the corresponding change of the pitch input.

The so-called "West Coast" approach to synthesis – traditionally associated with companies such as Buchla and Serge – is often based around adding harmonics to simple waveforms, rather than removing (filtering) them from complex waveforms. This is often accomplished by using a pair of oscillators (sometimes combined into what’s called a " complex oscillator") where one modulates the frequency (FM) or amplitude (AM) of the other; another common West Coast module is a waveshaper or a wavefolder. You may also find two-stage envelope generators such as an AD or AR (often called slope generators) rather than four-stage ADSRs, as well as more of an emphasis on control voltage manipulation, A common feature is also voltage controlled amplifiers that have low-pass filters built into them, creating what’s known as a Low Pass Gate (LPG). The West Coast approach also embraces non-traditional controllers, such as touch plates and the such. gas prices going up or down Today it’s common to mix both East Coast and West Coast approaches in the same system.
