I did write twice to the developer asking why but have not gotten any response...
So if it is available for you I do not know, but feel that being the only application that is multitrack with a synthesizer engine that is made for making microtonal work it would be interesting for anyone that wants to work or experiment with microtonal scales.
Icing on the cake is that each track can have its own time signature and separate scales on different tracks. Having conversed and read many times that this is definitively something that there is an interest in. So here you have it-
Any scale you can think of, any time signature for any track- So go to work and bend our minds with some far out never heard before tunings in full scale polyrhythmic chaos!
( The only complete app that can work in different time signatures with different and movable clips making it extra goody for polyrhythms is Syntheogen and with smaller workaround, SunVox. With some effort you can also work with microtonal scales in SunVox but not as easy as in Quencher ( I guess ) ).
As said have not tried the app but if you do please share with us what you think of the application... firstname.lastname@example.org
