This set of videos, from 1985, takes a look at The Secrets of Analog & Digital Synthesis.
It’s obviously dated, starting with the ”Listen to the sound coming from your VCR right now.” Nevertheless, there’s some solid coverage of synth basics and the videos also offer a vintage look at synths.
Little Scale, aka Sebastian Tomczak, has released SampleRider – a Max for Live instrument that uses a user-defined sample as a table for an oscillator.
Basically, a sinewave that is modulated by another sinewave sets the sample index for reading back sample points from the loaded sample. Frequency is set by incoming MIDI notes. Velocity sets volume. The user can define other parameters (e.g. modulating oscillator amount and frequency).
There are two main oscillators and two modulating oscillators. All timbral changes are created simply by reading back from the loaded sample at different points/in a different way.
Barrow shared these technical details on the piece, Solar Orbiter:
We start off with a brief intro using the Voyager XL and then the music begins with the Radias (Pads and the Lead Synth part way through the video) and the Moog Slim Phatty being used for the rhythm.
I then bring the XL in to play a moody lead synth (2 Osc’s used, the second used primarily for harmonic content). The Radias takes over later on and then we finish with Moog Slim Phatty and the Voyager XL.
