Idle thinking about synthesizers: Are there any components that CAN'T be described as a collection of the following items as inputs/outputs? * Level/Voltage (-1.0 to +1.0) * Frequency (in Hz) * Trigger (boolean)

Fixed LFO? Output Level. Step Sequencer? N Level inputs, 1 Trigger input, 1 Level output Variable LFO? 1 Frequency input, 1 Level output Fixed LPF? 1 Level input, 1 Level output Variable LPF? 1 Level input, 1 Frequency input, 1 Level output

, because I know you two think about synths :)

Analog or digital? In the digital domain, I ended up with synchronous state machines, running at two rates. One rate audio path, one rate control path. Some writeup here: zwizwa.be/rai - If you're into embedded, also check out axoloti.com

Definitely! I'm planning digital for now, and would like to take what I'm working with and move it to an embedded device, once I figure some stuff out. It's mostly just a learning project for me :) Thanks for the links!

Johannes did a good job with Axoloti, finding a balance between usability and DSP geekery. It's similar to a Nord Modular. Pure data is definitely DSP geekery and definetly something to check out. I played with that a lot.
