It turns out the littleBits keyboard isn’t faulty – it’s the oscillator causing the problem and it’s not a fault. The littleBits oscillator has a potentiometer labelled “pitch” and a little dial labelled “tune”. This is misleading. What the dial label should actually read is “calibrate”. I bet almost everyone using the kit thinks it’s a fine tune dial, but its real purpose is to adjust how the component maps incoming voltage to outgoing pitch. Very confusing.
Another piece using the sixteen steps of the SQ-1. This time you can hear clearly what the El Capistan is doing to the sequence. I wish the littleBits synth kit had a full ADSR envelope. It’s only attack and decay. Once you put the envelope in the chain, you lose the ability to sustain. The envelope just runs its course.
February, the darkest month of the year. Freezing temperatures. The flu. And this year, I’m working my way through a box set of soul-crushing slaughterfest “Game Of Thrones”. There’s no way I could do anything but a dirge this week.
The humble littleBits Synth Kit producing some fairly good strings. Of course, it’s the not-so-humble BigSky that’s doing most of the work. It’s set on cloud mode. And the El Capistan is mangling the wave pre-reverb to give some depth. More detune between the oscillators would give a richer sound, but for the reasons listed below wasn’t practical. Volca Beats providing barely audible drums and Volca Bass filling in the bottom end.
The biggest problem with the littleBits Synth Kit is tuning and tracking. I can have two oscillators perfectly in tune, but come back the next day and they’ll be out of whack. This is at the same room temperature and after they’ve had some voltage through them. Then there’s tracking. Regardless of conditions, an octave on the keyboard is never an octave on the oscillator. And the margin of error seems to vary depending on which oscillator module I’m using. That’s why much of this stuff I’m doing sounds out of tune half the time. There’s no way to compensate.
