GR-20 Hexaphonic 19-ET Guitar Improvisation

Description
This study entailed learning how to simultaneously play six instances of z3ta+ in 19-ET tuning with my Fender Mustang using a Roland GR-20 as the guitar to midi interface.

I improvised in an ambient-ish style and explored the fret board combinations both in both harmonic and timbrel relationships with some melodic considerations.

The GR-20 has a mode in which each string of the guitar is assigned a midi channel, channels 1 through 6. Thus hexaphonic output is possible. In this case each string’s output is sent out the GR-20 through a midi to usb adaptor into my laptop and then into Sonar 8.5. In Sonar I assign each string an instance of z3ta+ – a software synthesizer that comes with Sonar that is microtonal capable. Each of the six instances of z3ta+ have a unique preset voice assigned and has a 19-ET tuning file loaded. In the case of the high E string, channel 1, which sounded too high for me, is transposed at Sonar by -19 midi notes which yields the octave below the one I’m playing when using 19-ET.

One of the points of doing this is to make each string spatially different – in stereo-space the strings are arranged 5 3 1 2 4 6 in increments of 20%, i.e., 20, 40, 60 percent off center each side. No hard panning allows some of the stereophonic aspects of the zeta+ voices to be heard.

The video is for Feter to demonstrate the performance (such as it is) with the same set of synthesizers.

Hi Feter
I will arrange to have a video taken of another improvisation and post it to youtube. The real info is I'm finger picking classical style. And slowly at that - the most of the synth patches have slow attacks.
