  • Microtonal Combinators for Propellerheads Reason

    Reason lacks when it comes to microtonal scales. There is a RackExtensions for applying 12-tone temperatures called MicroTune http://res.ochenk.com/microtune/ but the tuning I mostly use has more than 12 tones in one octave. And in addition I want to play polyphone (at leat 4-voices-chords).

    Fortunately, synths like Thor and NN-XT support keyboard-tracking in their oscillators. So retuning them to my preferred scale is no problem (it is not that exact, but I can live with a minimal stretch of about 4 cents per octave). By the way, in Ableton Live the Sampler has the same option.

    For the other synths like Subtractor, Malström and some 3rd-party RackExtensions I developed 2 Combinators: one for monophonic synths and one for polyphonic synths.

    It didn't work completely without any RackExtension and after messing around with MicroTune I searched for another way. The trick is to use PitchBend in the range of one octave. (MicroTune uses PitchBend too but only in the range of one semitone).

    For the polyphonic Combinator I had to split the CV-signal in several monophonic parts because PitchBend always applies to a whole synth and not per note. This is done by the following RackExtension http://res.ochenk.com/a-series-2-modular-synth/

    The monophonic Combinator needed a way to change the PichBend-value slowly for being able to play with glide/portamento without glitches. This is done with http://hamu.se/root/rack-extensions/modslewer.html

    Then I encountered some glitches while playing the polyphonic Combinator and the monophonic one without portamento. I needed to delay the CV-gate values about 30ms, and this is done with http://www.jiggery-pokery.com/jp_re/lolth.html

    Acually the 2 Combinators are in a raw state. If anyone is interested, I can send them per mail.

    In the VST-world there are a lot of synths too that lack microtonal scaling options. All my researches for a solution failed and the only way I see here is to program a VST-plugin that does the same PitchBend-trick. But that's a far more complicated thing than routing cables in Reason.
