Ha! I’ve been hanging out in the 63-68 bpm range lately on my Digitone. But I can’t seem to do melodies and beats well right now so it’s been soundscape city for me.
I did a live show with some industrial techno guys last spring and they practically fainted with expressions of “system error!” when I told them my set started at 54bpm . It was partially so I could at times run the Machinedrum at 2x speed while keeping my initial melodies slow and heavy. And the set did speed up at one point to 153bpm.
That’s the range I really like too when I have beats going.I’m probably really 90-110. It’s laid back, but not too laid back. I try and push myself out of that range but I stray back to like 93 or 107 too easily.
(The 54 bpm song came about as a half of 108. I was running something at half speed or double speed to get extra room out of my patterns and it kindof took over).
I often multiply tempo by 2 in a song. If you multiply tempo by 1.5, you can apply a 5th pitch to samples.
I you multiply by 2^(1/12), you can add a semi-tone.
Tuned tempi :
103.125 > A tuning tempo, for rolls, retrigs
122.64 > C tuning tempo.
Etc…
The B.B.C. tuning-note is derived from an oscillator controlled by a piezo-electric crystal that vibrates with a frequency of one million Hz. This is reduced to a frequency of 1,000 Hz by electronic dividers; it is then multiplied eleven times and divided by twenty-five, so producing the required frequency of 440 Hz. As 439 Hz is a prime number a frequency of 439 Hz could not be broadcast by such means as this.
