Re: [music-dsp] 14-bit MIDI controls, how should we do Coarse and Fine?

I think that what some of this discussion is missing is the hardware side. MIDI (hardware interface) can only transmit 3125 bytes/sec, which is a drop in the bucket compared to anything modern (but is generally bulletproof when implemented correctly). I've had the misfortune to be on a team specify

Re: [music-dsp] Using an actual database for storage of DSP settings

Maybe, maybe not. One problem with sqlite is multiple setters. One tool I use at work needed to change from the default sqlite to poqtgresql because we used a new feature that had many processes attempting to access the database simultaneously. Not a problem if you're just using it to organize dat

Re: [music-dsp] What happened to that FPGA for DSP idea

Hi everyone, Some of this stuff looks an awful lot like the development of computer graphics technology. First, there were fixed pipeline software renderers. Then, as the software renderers were starting to have programmable pipelines, dedicated hardware came into use. But the hardware used the

Re: [music-dsp] Playing a Square Wave

Theo, My tl;dr answer to your question is it's difficult because even if it's digital, it's not digital. Ever. It's always analog. Like you, I'm a university EE (and Comp. Sci.) because I wanted to go into chip design. This was back in the early 80's. So maybe my classwork was different than your

Re: [music-dsp] Sound Analysis

Robert, The tonewheels are intended to be perfectly sinusoidal, though their mass stamping does introduce various differences. The execption is the lowest octave of certain models, B3 included, made at certain times, as described here: http://www.dairiki.org/HammondWiki/ToneWheel Given the inten

Re: [music-dsp] Auto-tune sounds like vocoder

I have an unproven theory about that. The vocal tract has different filtering characteristics at different pitches. If you take a vocal sound and just pitch-shift it, you're also shifting the filter characteristics, and that doesn't sound right. I imagine that some clever person could do somethin

Re: [music-dsp] An example video: C to FPGA programming

Andrew, I think that the information at http://www.clifford.at/icestorm/ would be useful to you. It describes the icestorm toolchain and uses Lattice's development boards. I've done some musical things using both the smaller and larger boards. It's a pretty inexpensive way to get started. Neil G
