Delta Build Blog #2 (It’s Alive!)

New CPUs arrived last week (I bought a spare this time) and after a few tweaks I’m happy to report it’s alive. All four voices are now making basic sounds, in my case each voice has two oscillators, each running a saw tooth and slightly detuned. I’ve done a very simple VCF sweep with sweeping the VCA level and recorded it with some different values of resonance.

Delta VCF sweeps

This is only once voice right now, the next step will be adding very simple MIDI control and mapping of CCs to allow me to control the parameters.

Work has been progressing with the mechanical design as well, I do have some renders, but I’m not yet ready to share them. Once I’ve got all the features fully implemented on a single 4 voice card, I’ll be sharing the renders at that point. It does look stunning and unique though (yes, I’m a tease).
