Denial

When playing tracked music there's this effect called "arpeggio" where a chord is simulated by playing the notes of the chord in very small time slices over a single sound channel. Now I was wondering if this technique could also be used to play not just chords but independent notes, so to simulate a greater number of channels (e.g. 6 instead of 3).

Has this ever been tried on the VIC20?

I don't know about more voices, but people have found a way to improve each voice.

Example here: https://github.com/ThePhotoChemist/Fami ... /README.md

It works if the composition does mainly consist of fast alternating notes which are all of the same length - not as a generic technique that doubles the channels

I have a similar question about digitized speech in small time slices. I am pretty sure there would be an audible 50/60Hz hum though.

I did this for cheesy Trials. Sounds a little zx spectrun-y
