LinnStrument as a Microtonal Controller – Split Mode

Wednesday, December 7th, 2016

Here is a short demonstration video of the split mode as implemented in the original Linnstrument. By using the split mode one can access all 200 pads. With a judicious selection of synthesizer and range one can extend a tuning well beyond the current midi standard of 128 notes. The short demonstration piece uses two non-octave tunings => 5/4 divided into 4 and 5/4 divided into 8 notes respectively.

Simple Passwords (5th root of 7/6)

Simple Passwords is a proof of concept improvisation. Here I use Fractal Tune Smithy 3 to retune my Linnstrument’s output in real time to play Moog’s iPad app Animoog connected by rtpMIDI in a decidedly microtonal tuning via pitch bends. – Its not perfect as some shifts are heard in held notes,though as with my gr-20 retuning work I feel confident this will be worked out once I find the proper settings. Frankly I find this to be exciting because almost any iPad app can be played in an alternate tuning by this method.

Mt. Herschel is an practiced improvisation using pianoteq in 10 edo and my Korg MS2000 in a close to 10 edo tuning by using keyboard slope. Below is the Melodyne output of a short section of the tuning played “chromatically” with a softer timbre.

There was a preceding experiment using a different keyboard slope tuning – synthesizer only
