just intonation with pitchbend video

This is a YouTube video of keyboard played in 5-limit just intonation with liberal use of pitchbend using a ribbon controller. I wonder if anyone will find this particular technique of interest. I have not seen a keyboard instrument played in just intonation with pitchbend in this way elsewhere.

Thanks for posting. Looks like a Kawai MP5 and a Kurzweil K2000?
Ribbon controllers certainly are fun.

Yes, that's a Kawai MP5 keyboard. Nice smooth action with some heft to provide touch sensitivity. I find it better for synth control than for piano. That's a Kurzweil K2661 in the picture, though it is not being used in this example. The tone for the melody is being produced by a Korg Radias, a Korg Z1, and the Korg OASYS PCI -- all tunable to one-cent resolution. Unfortunately the audio quality is poor due to the camera used and engineer error (which can and will be rectified in future attempts).

The ratios of the scale used in the piece shown are 1/1, 16/15, 6/5, 4/3, 3/2, 8/5, 9/5. I love those low prime ratios! The key to the sonorities potential with this technique is that the pitch bends both begin and end on pure just intervals -- the bending is done with high-precision. This is possible to due the use of the Doepfer R2M ribbon controller carefully calibrated for accuracy of intervals.

Hi msavante,

Thanks for the details. Doepfer rocks! A bit harder to get
here in the states, unfortunately. The OASYS PCI card is a
real legend. I love its physically-modeled electric piano.
I believe Ozric Tentacles used to employ a Z1 to good effect.

Keep it up!
