Hearing the differences between linear and exponential response in envelopes and amplifier (VCA) response
- I'm gonna apologize upfront, this is gonna be…one of the geekiest movies in this entire course.…However, it's a subject that trips up a lot of people.…It's the shape of envelopes, linear or exponential.…Some envelope generators, as well as some VCAs,…voltage controlled amps, have a separate switch…for linear or exponential.…What does that mean?…It has to do with how the voltage changes over time…and how the amplifier responds to that voltage.…Linear is a nice constant rate up…and a nice constant rate down.…
Exponential implies a rush up and then a rush back down.…That curve, the exponential curve, actually matches…how we hear pitch and also how we hear loudness.…So, an exponential curve would…actually be more natural for creating envelopes.…That's why many envelope generators…are actually exponential by nature.…Now as it so happens, if you have an attack that rushed up,…it's gonna sound weird, it's gonna sound…like something playing backwards.…So, envelope generators tend to actually have what's called…a logarithmic attack, where they…
This course will be based around the widely available Roland SYSTEM-500 Eurorack-standard synthesizer modules, complemented with modules from several other manufacturers. As most modules, synthesizer keyboards, and plugins are designed around the same principles, this course lets you dig deeper into synthesis and programming your sounds regardless of the equipment you own.
- Putting a system together
- Getting sound in and out
- Patching a typical synthesizer "voice"
- Tuning voltage-controlled oscillators (VCOs)
- Working with waveforms
- Using filters
- Exploring frequency modulation, waveshaping, oscillator sync, effects, and more
