Aurora Control PCB

Monday, January 28th, 2013

As mentioned previously, I dug out a control board I’d used for another project a while back and decided to use this for Aurora.Today I added the various wires needed and tested the board, so far so good. This will let me send MIDI to the voice to test things like envelopes, pitch tracking and […]

You’ll now find VacoLoco on Pinterest, I’m still finding my way around it but I thought it might be useful for sharing photos of projects and progress.

Aurora gets an LFO

Sunday, January 27th, 2013

Tonight was quite productive, I managed to add an LFO to the Aurora Voice card. It has four wave shapes; sine, sawtooth, square and random. It has a variable rate from very slow to very quick, a delay (which fades in) and the ability to restart the wave when a new key is pressed. A […]

Aurora Waveform Demos

A quick update about Aurora, I’m still working on it but there’s not much to show at the moment. I’m playing with the oscillator code so I can add a few more waveforms, but critically I’m adding variable pulse width so Aurora can have PWM. I’m also investigating how best to get a decent quality […]

JuJu, the return

Sunday, January 13th, 2013

Whilst waiting for some parts to arrive for GorF-XL and Zira, I decided to pick up an old project, JuJu. JuJu was to be a drum brain, but playing back samples from things like the Linn drum and Oberheim DMX. The problem I had with JuJu was that I wasn’t able to get the samples […]
