Programming in early 80s synth music

'In general' is pretty hard to nail down. There is so much to say about this era I could write a book - perhaps I should ;-) Late edit - Let me add a quick TL:DR Hardware sequencers were such a pain ...

Do different synthesizers have different timbres and/or produce different harmonics for the same given waveform?

They are not identical. The differences are suble, but often audible. Different implementations of both oscillators and specific waveforms will yield slightly different timbres. The rest of the signal ...

Is it mathematically possible to create an equal temperament which matches just interval ratios?

The other answers approach this from dividing the octave and showing that equal divisions must be irrational. Another way of looking at this is to consider whether we can compose an octave by ...

What are the practical advantages of keyboards with non-weighted keys vs. weighted hammer action?

What I've found is that the acoustic piano is the most expressive when played softly. We all like loud, but anything can be loud and the ear will tune loud OUT after a while. But it pays attention ...

What's the difference between two notes played on strings of different thickness?

Technically speaking two notes with the same pitch have the same frequency as the fundamental. However this does not explain why two notes of the same frequency also called unisons, sound different ...

Why do some synthesizers have two or more oscillators?

Firstly, a single oscillator will tend to produce rather a subjectively 'thin' and static sound. This isn't always the case (as later stages, such as the filter, or a separate chorus stage, can add ...

Synthesizer: why playing a second time the same note shut down the first one?

The MIDI specification says: If an instrument receives two or more Note On messages with the same key number and MIDI channel, it must make a determination of how to handle the additional Note Ons. ...

Is it mathematically possible to create an equal temperament which matches just interval ratios?

As I understand the question, this is pure mathematics: No it is impossible. No matter, how many divisions you have, say n, the step width will always be nth root of two and therefore an irrational ...

What would happen if I played two or more notes on a monophonic modular analog synthesizer?

In a monophonic MIDI to CV module it would just send one note through. It is called note priority, and the implementation depends on the MIDI to CV module. Some modules will let you switch between ...

Can I plug a 2.5A 250V~ cable to a synth that is 100 - 240v?

The 2.5A and 250V on the cable is just the highest current (Ampere) and voltage (Volts) that it's safe to use at. Provided that your mains supply is in the range 100V to 240V then that's no problem. ...

Why does software-synthesized MIDI music sound so bad?

MIDI is not sound. The MIDI specification does not dictate what any instrument sounds like, it's up to the synthesizer to generate the sound. Free synths sound like crap, but good ones can sound as ...

Duration of a quarter note with a 3 written beside it (on a synth display)?

Synthesizer: why playing a second time the same note shut down the first one?
