Analog Modular Control of BFD or EZDrummer with the Alesis Trigger IO

Analog Modular Control of BFD or EZDrummer with the Alesis Trigger IO

I had a lot of fun building out the Probabilistic Trigger Sequencer. It’s a great compositional tool when you need some spacey, almost predictable beats, and it got me thinking about how I could use the same analog control for something a little more dynamic. I am a BFD user, but there are quite a […]

Oscillator Framework part 2: Variable Sample Frequency Wavetables

Oscillator Framework part 2: Variable Sample Frequency Wavetables

Who doesn’t love a wavetable synth? Who in their right mind doesn’t immediately think of a wavetable synth when cataloging the possibility tied up in an Arduino? Quite a few seem to be like minded as there are numerous blog posts and even a fairly in-depth article in Wired about implenting a wavetable synth on […]

DAC output circuit

DAC output circuit

While I was working on another post, I made a few recordings of the signal straight off the Due DAC and then recorded the same through the output circuit. I just thought I might share the sounds and screeenshots of the waveforms. The DAC output circuit is shown above. It’s basically a bandpass filter. But […]

Bluetooth Pairing

The nw2s::b uses the bluetooth connection for two things. Uploading new sketches (really it’s firmware) Issuing commands to the current sketch The bluetooth module included with the nw2s::b is built by Adafruit and is very easy to set up and get running. It uses the SPP standard which most operating systems support with no additional […]

CV controlled sequencer

CV controlled sequencer

No new code to demo this week. Instead this is a new application of existing code. The melody is a sequence whose position is determined using a CV signal. To “play” the sequence, you apply a CV signal, or in my case, you just twist the input potentiometer back and forth a little at a […]
